The EPA got slammed in 2017 when it turned out that a nonionic surfactant used in Monsanto’s Roundup Ready mixture was actually more toxic than the glyphosate itself (polyethoxylated tallow amine or POEA). Sorry, your blog cannot share posts by email. Copyright © yearofthedurian.com - Powered by Love for Durian. It was developed as a sulfur-based fungicide, but has had many uses over the years, including as a treatment for human scabies and in soap for various skin conditions. So with that in mind, I was curious to see what kind of chemicals Ruenrom was selling in his shop. *Please note that this is not ALL the chemicals used on durian in Thailand. Durian (Durio zibethinus) is known as the King of Fruits and is the most highly prized fruit in Southeast Asia.Revered in Asia for its exquisite flavour and taste, its overpowering and distinctive odour makes it less popular in Western countries and cuisine. Of the three, only TM is still permitted in the United States, although who really knows why that one’s allowed. PubMed:Comparison of aroma-active compounds and sensory characteristics of durian (Durio zibethinus L.) wines using strains of Saccharomyces cerevisiae with … They wanted something more shelf-stable, longer-lasting in the field, and more effective. ERAFOSTYLAluminum tris-0-ethylphosphonate This brand is Erawan. Water is a chemical (formula H 2 O). Approved For Use on Food Crops?✅Australia✅Canada ✅European Union ✅Japan✅United States. We were lucky enough to meet Santos Ruenrom, a local “Tree Doctor” who owns an agricultural chemical shop in Rayong, Thailand. That has included everything from cyborg bugs to shouting matches in Congress. An American named Milton Schelton began synthesizing human-made versions isolated pyrethrins in the flowers (remember there are 6 separate pyrethrin chemicals). Rather than nihilistically throwing up our hands and assuming we’re all being poisoned with every bite — let’s learn about durian pesticides! Don't know who started it, but do not believe in hearsay. Actually, some natural chemicals which are allowed in organic farming can cause more problems than a weak pyratroid in the case of killing soil microorganisms. Which was probably as bad for human health as a modern day pesticides. Shipments of fresh durian to the USA, Europe, Japan, Hong Kong and Australia have been rejected due to excess residue of Carbendazim. Ruenrom knew what to do, and promptly sold her a natural anti-fungal to take care of her fungal issues. However, it is an antibiotic. What Was It Like When The Universe First Created More Matter Than Antimatter? Plant Density: 88 – 115 tree/Ha. Another Sulfactant recently been criticized is nonylphenol ethoxylates, which has been found to mimic the female hormone estrogen. PubMed:Food Compounds Activating Thermosensitive TRP Channels in Asian Herbal and Medicinal Foods. Some of the other chemicals smell fruity or like honey. You’ve already eaten fruit sprayed with Fosetyl-Al. Farmers use lots of compost along with non-organic NPK fertilizers. Which means that it’s pretty benign in the environment and to human bodies. One compound apparently smells like soup seasoning.¯\_(ツ)_/¯. The durian fruit is a good source of antioxidant vitamin-C (about 33% of RDA). Concerns about carbendazim’s toxicity were raised as early as 1996, when a Miami mother won a court case for her baby born without eyes. Fosetyl-Al is most dangerous for the workers spraying it. Even the WHO has promoted using pyrethroid insecticides to reduce insect-borne disease like malaria. If you need an organic surfactant, there’s always sugar. It’s used on everything that could possibly get root rots or stem rots and mildews, including avocados, pineapples, blueberries, cranberries, citrus, leafy greens, onions, peas, macadamia nuts, turnips…. Durians contains a lot of chemicals? This isn’t much of an issue. My work has appeared in Chemical & Engineering News, Slate and on YouTube. Soil Type: Medium – Heavy. If you’ve never smelled the durian fruit, grab some onions, turpentine, a pair of dirty gym socks and maybe your dead grandmother. This bacteria was first discovered around 1944, when it was used in humans to fight tuberculosis. I think we need to strive for healthier agriculture, not just for the consumer but for the workers and especially, the soil. The company sells a wide range of quality products in more than 100 countries through 16 subsidiaries spread throughout the world. When combined, however, these two chemicals were indistinguishable from the durian odour. Ever wondered exactly what pesticide residues might be lingering on your delicious durians? Every year, Thailand’s fruits get rejected from places like Hong Kong, Taiwan, European countries, and the USA. As an exotic fruit, durian is relished for its strong aroma and unique taste. He made a killing 😆. PubMed:Assessment of volatile and non-volatile compounds in durian wines fermented with four commercial non-Saccharomyces yeasts. Paclobutrazol was inspired by electricity companies trying to keep power lines cleared and golf courses trying to spend less money on mowing the lawn. So why not use just soap or detergent to make your active ingredient more sticky, like in Medieval Age? It also can deter rodents and small mammalian pests that don’t like the sulfurous aroma. It’s a fungicide and protects the tree against all kinds of root rots and stem rots and mildews, including the ever-pernicious and evil Phytophtora. Since they are highly toxic for soil organisms, Carbendazim has also been used on golf courses and sports arenas to kill earth worms that would otherwise leave their little muddy poos all over the top of the lawn. Sulfur doesn’t mix well with water, making it clumpy and difficult to spray – easily clogging hoses and sprayers. This is a long read — definitely for you health and agricultural nerds ONLY! By the late 1940’s, scientists already concerned about the health effects of widespread DDT use in agriculture began looking for alternatives. Thailand’s Bureau of Agricultural Commodity and Food Standards lumps the benzimidazole triad — Benomyl, Thiophenate-methyl, and Carbendazim — together when discussing pesticide residue — which the EPA DOES NOT. Ask Ethan: How Large Is The Entire, Unobservable Universe? All of this makes me wish my high school chemistry teacher had been less interested in funny cat videos and more interested in chemical bonds and hydrophobic somethings. But it turns out this souped up sulfur is more than a fertilizer. Carbendazim and Thiophenate-methyl (TM) followed in 1970 and 1973. These were followed by chemicals with strong notes of cabbage and sulfur. Surfactants are a huge family of chemicals that basically make the active ingredient stick to the leaves/roots and make whatever the fertilizer/pesticide/fungicide more effective. That would approximate how people—at least Westerners—say it smells. CARBENDAZIM (MBC) and THIOPHENATE-METHYL (TM) A 2015 study found that Carbendazim and its Auntie TM are the second most common fungicides in Thailand, which is a little scary. In the USA, the EPA classifies Validamcyin as Class IV or “Practically Non-toxic.” It breaks down very quickly (with a half-life of less than 5 hours) and doesn’t leave residue in the soil or water supplies. Pyrethrins: A family of the 6 toxic esters found in Chrysanthemum flowersPyrethrum: An essential oil made from Chrysanthemum flowers that is high in pyrethrins, usually containing a blend of all 6 esters. Systemic is very different from contact toxins which may not be absorbed by the plants, depending. Important minerals such as potassium, iron, calcium, magnesium, sodium, zinc, phosphorus are also found in durian. So the Rhizoctonia starves to death (and the crowd goes wild 🙌🙌). In the 1920’s, German scientists isolated the 6 pyrethrin esters in the daisies and learned how they work to kill insects. It breaks down quickly into other chemicals, primarily Phosphonic Acids, which are a huge class of chemicals that coincidentally include glyphosate and etephon. Thank you for the feedback Paul! Nicknamed “Fosetyl-Al,” this one is common in conventional agriculture pretty much everywhere. Durian trees: Fertigation & foliar feeding recommendation . Root stimulation is used in all agricultural crops to make plants hardier and less likely to fall over. It’s used specifically for killing spider mites – teeny bitty arachnids that damage fruit. It also contains nutrients such as phytonutrients, … The Dalmation Daisy (C. cinerariifolium) is deadly, if you’re an insect. Too much durian is poisonous? It’s a corrosive and can be really damaging for the eyes, so the EPA suggests wearing goggles when applying it to trees. Myths! 3. We want to thank him for taking the time to walk us through each product on the shelf. I studied chemistry as an undergrad at Carleton College, but it’s as they say: Those who can’t do, blog. The application of amendments, even when not strictly within what is allowed organically would not be a problem for me. The Same Reason You Would Study Anything Else, The (Mostly) Quantum Physics Of Making Colors, This Simple Thought Experiment Shows Why We Need Quantum Gravity, How The Planck Satellite Forever Changed Our View Of The Universe. Required fields are marked *. In 2008, two court cases in New Zealand were settled after more babies were born without eyes. Ethanethiol is sulfur-smell easy for anyone to pick out. But it’s unlikely that you’ll eat much lamda-cyalathrin as a residue, especially not on durian. Pesticides have been a huge topic of national debate in Thailand. The first recorded agricultural surfactant (literally soap) was mixed with *arsenic or sometimes lead* as the active ingredient and spread on food crops as an insecticide during the Medieval Ages. Chemical control is executed by scrapping the bark of the infected area and painting alliete fosetyl alluminium (alliete) or metalaxyl (Ridomil). ***I am also not an agricultural scientist. It’s well known that Paclobutrazol does not break down quickly in the soil – a perk if you don’t want to keep reapplying but a downer if you want to plant anything else around your trees and have the new crop actually grow. The chemical inhibits the production of the plant hormone Gibberellin, forcing the plant to grow a sturdier base/trunk, a stronger root system, and in general just grow really slow. All pyrethrins, synthetic or natural, are toxic to ALL invertebrates. The ones still derived from the flowers? However, if you’re a farmer reading this, maybe consider trying the natural-form of pyrethrins? But please don’t do that. The science behind the malodour lies in a rare amino acid called ethionine. Durian is an evergreen, tropical tree found in southeast Asia. The Australian Pesticides Authority says that exposure to Carbendazim can result in “irreversible male infertility.”. Surfactants function using the chemistry of water molecules. You get the idea. Durians are injected with chemicals, thus some varieties are so fleshy, very strong tasting, bitter or sweet, etc etc? The scientists made up a bunch of mixtures, leaving out aroma chemicals one by one to see if the experts could tell the difference between those and a reference durian smell. Your email address will not be published. Depending on the degree of infection, both chemicals can be used in combination such as foliar applications of fosetyl-Al and soil drenching with metaxyl. I couldn’t find a Nutrition Label for exactly which nutrients are being targeted, but I’m assuming it’s like a compost tea. The durian attracts various types of pests, and without the chemicals, most of the places growing it would not be able to turn any profit, as large quantity of fruit would perish. 1985. One of the concerns is “drift spray” where the pesticide drifts out of the field and into the neighborhood, where contact can cause skin rashes. They should be using the much much safer glyphosate. Like other antibiotics, there are fears that widespread use of Validamycin might create resistant strains of Rhizoctonia, the MRSA of the fungal world. You could, except if you choose an anionic kind, they might bind with the calcium and/or magnesium in your soil *instead* of the active chemical, giving your plant a nutrient deficiency. Durian is rich in dietary fiber, which makes it a good bulk laxative. There were 3 or 4 different brands, and each have enough miraculous benefits that I wonder if the CEO is Donald Trump. The spiky fruit grows in southeast Asia, where it is eaten both raw and cooked. Later I researched the toxicity, environmental affects, and whether or not it’s approved for use in the USA. All Rights Reserved, This is a BETA experience. So much useful information, organized in such an easily accessible format. Durian. This method by scraped away the infected durian bark and painted with fungicide. The first group of bottles we picked up had pretty pictures of fruits all over the labels. In response, netizen @syafawaniiiii explained that there are certain chemicals in durian that are similar to garlic, which gives you that feeling of eating something spicy. It turns out that not only does Paclobutrazol keep trees shorter and sturdier, it also works as a fungicide, gives a darker green color to leaves and lawns (so prettier golf courses), and even changes the way plants absorb water, making them more drought resistant! It’s all used a lot for root crops, like carrots, beets, potatoes, etc. ... only to realise a durian caused the smell, a statement on the library’s Facebook page read. Full disclosure: I’m a former employee of the American Chemical Society, which publishes the Journal of Agricultural and Food Chemistry, and a current contract writer for the society’s Reactions video series. As the weather gets drier they want to apply potassium to force/support flowering. The Bad Thing is that the US EPA has been slow about assessing their impact on the environment or really regulating them, since they are basically considered non-active ingredients. There’s a huge movement in Thailand and within the Durian Farming community toward less toxic agro-chemicals. It might be good to the feed the soil with the equivalent of agricultural yogurt after spraying with Validamycin. Together, they were indistinguishable from the durian odor reference. Several technologies such as gasification, pyrolysis, (Zhang et Food safety and health safety is on everyone’s mind today, but the agricultural chemical world is still mysterious and confusing to most of us. It’s a complex mixture. Ideally all the durian farms would be organic and we know that, on a small scale at least, it can work well. ... Prof Yeah cautioned that overuse of pesticides and chemicals might … So I really don’t feel I can say whether or not eating Phosphonic acid residue is safe or not. Validamycin is a natural toxin produced by Streptomyces hygroscopicus var. Purdue. Materials and methods Chemicals and standards Anhydrous magnesium sulfate, sodium chloride, primary and secondary amine (PSA, particle size 40 lm), graphited carbon black (GCB), and C18 sorbent (particle size 40 lm) were purchased from Supelco (Sigma–Aldrich Corp., St. Louis, USA). It seems to be non-toxic to mammals and birds, but is stated “paclobutrazol is very toxic to aquatic organisms.”, ✅Australia✅Canada ✅European Union ✅Japan✅United States. For centuries, the flower heads were dried, pounded, and sprayed in gardens and on lice-infected heads as an effective insecticide. ✅Australia✅Canada ✅European Union ✅Japan✅United States Bayer Company sells Fosetyl-Al under the name “Aliette.” You can buy it at gardening shops or even on Amazon. A Japanese university found that the high sulfur content in durians inhibits the activity of an enzyme responsible for metabolising alcohol in the liver. For example, Plantonics Fruit Special Blend from an Indian company, Gujarat Bio Organics, claims to help trees deal with the stresses of global warming and atmospheric pollution, as well as improving fruit taste, size, weight, color and overall attractiveness and creating an unforgettable taste. Propargite was first registered in the United States in 1969 by Uniroyal Chemical Co, which then was repeatedly sold and merged and sold and merged until I’m confused. Durian is banned from many public spaces in Southeast Asia due to its powerful odor. These pretty white-petaled flowers come from the Balkan Mountains in present-day Bulgaria. According to World Atlas, Thailand is #4 in the World’s Top Pesticide Consuming Countries (but still behind the USA, #2). But using Paclobutrazol has a lot of other perks too. For my own consumption the two systemic fungicides, aliete and benomil, worry me. Contemporary studies show that Thiram exposure may be damaging to the thyroid and liver. It doesn’t seem to hurt bees, and is non-irritating when rubbed on the skin of rabbits. The fiber content helps protect the colon mucous membrane by decreasing exposure time to toxins. Ethanethiol, one the chemicals found in the durian fruit, is commonly added to non-smelling gases like propane so we can easily smell dangerous leaks. Image Credit: GreenBlender. They feed them, water them, take care of their boo-boos, and try to make their trees the healthiest and most productive forms of themselves. At first glance I thought this floppy bag was just a fertilizer. Natural pyrethrins ergo pyrethrum can not be widely adopted as substitutes because they are ALOT more expensive and, more important, break down in 24 hours whereas the synthetics e.g. Molecules. A mixture of chemicals in the fruit creates its unique scent, according to Smithsonian. A mixture of chemicals in the fruit creates its unique scent, according to Smithsonian. Durian seeds are mainly composed of starch and mucilage (gum), which influence its properties and hence the potential applications. In the late 1800’s, John Zacherl made his fortune selling powdered Dalmation Daisies as an insecticide he branded Zacherlin. So the scientists have basically mixed finely ground sulfur with gold nano-particles to make it easier. Next, researchers Martin Steinhaus, Jia-Xiao Li and Peter Schieberle did tests with a panel of trained smellers. Durian (Durio zibethinus) is an exotic tropical fruit grown in Malaysia and throughout the Southeast Asian region. ✅Australia ✅Canada✅European Union ✅ United States, In the USA, this product marketed as Microthiol® Disperss®. But this bag is more than sulfur — it’s “Sulfur and Science” — and that’s hard for a layman like me to decipher if that’s a good thing. This will followed by other fungicide such as metalaxyl, fosetyl aluminium, milfuram or cyprofuram. It’s a very complicated subject since it involves adding an ingredient to an entire ecosystem — and there is so much fear about words like “pesticide” and “chemical” when as you mention isolated organic compounds can also be very harmful — like when they sprinkled arsenic or lead dust on plants in the middle ages to act as a pesticide! In the 1970’s, the US CDC (Center for Disease Control) began questioning the safety of Thiram after a study on nursery and forestry workers reported nausea, dizziness, headaches, stomach complaints, and, unsurprisingly, intolerance to alcohol. Vitamin C is a chemical (formula C 6 H 8 O 6). As mentioned previously, durian has a wealth of vitamins, nutrients, and organic chemicals that function as antioxidants. The researchers published their results in the Journal of Agricultural and Food Chemistry. Healthy soil takes care of root fungus, this is long term care of the soil that is often overlooked with little appreciation of the importance of a living soil. This means that water can mix with and suspend a chemical inside it — whether that’s a pesticide or a just a nutrient. Beginning with the post harvest, they prune the trees and apply compost and regular fertilizer to stimulate foliage growth during the rainy season. But for me, that bug fueled my imagination. The process takes time, repetition, and guesswork. Validamycin works by preventing the Rhizoctonia from producing the enzyme that converts its food to sugar, trehalase. It also helps bind and eliminates cancer-causing chemicals from the gut. Shipments of fresh durian to the USA, Europe, Japan, Hong Kong and Australia have been rejected due to excess residue of Carbendazim. I am not sure which is more currently considered more toxic, Paraquat or Round Up. One smells onion-y, the other fruit. Carbendazim binds tightly with soil and doesn’t appear to run off into water supplies — which is a relief — but it also doesn’t break down quickly. As an independent journalist, I write about what's…. Fruit farmers in southern Vietnam are injecting their produce with chemicals to make them ripen quicker and go rotten slower. Try as I might, there is just no jazzing up photos of bottles covered in Thai script into a titillating visual experience. ✅Australia✅Canada ✅European Union ✅Japan✅United States – Bonzi®, Clipper®, Coltar®, Trimmit®, Profile®. Opinions expressed by Forbes Contributors are their own. It can pay off. This is not a comprehensive list, just an explainer of what we saw in one Agro-chem shop on one day in Thailand. According to a 2009 Japanese study, durian extract strongly inhibits the enzyme aldehyde dehydrogenase (ALDH), used by the liver to break down alcohol. Durian, a fruit called the ‘king of all fruits,’ is exceedingly popular in many East Asian countries. After my own research, I would like to see farmers shift away from using these 3 chemicals specifically: Not because of residue left in the durian flesh, but because of the possible health effects on orchard workers and the environment — rivers and streams seem to take an especially hard hit. The distinctive fruit has a spiky outer covering and smells of rotten eggs. In the battle against cancer, free radicals are vitally important, because during cell metabolism, there are byproducts created, called free radicals. They were also planted in garden as companion plants to ward off the creepy-crawlers. It breaks down in sunlight in a matter of days and doesn’t dissolve easily in water. Notify me of follow-up comments by email. If you missed high school chemistry 🙋, this Youtube video by Dow Agrosciences gives a pretty good explanation of how this works. The last bottles we came to were complicated. Post was not sent - check your email addresses! Eco groups have also advised that birds and small mammals that eat seeds are more likely to be exposed to Thiram, and raised concerns about endangered species, like Attawar’s Prarie Chicken, coming into contact with Thiram. The toxins paralyze the insect by disrupting sodium transport in the nervous system, effectively giving the insect a huge body-wide Charlie Horse muscle spasm. 2-(4-tert-butylphenoxy)cyclohexyl prop-2-yne-1-sulfonate-whew, ✅Australia ✅Canada❌European Union ✅ United States. ✅Australia ✅ Canada❌European Union ✅ United States. Folates are a group of vitamins and are essential nutrients for humans. A non-profit agency, the Thailand Pesticide Alert Network, has reported that nearly 64% of Thai produce exceeds its MRL (maximum residue limits), and should be deemed unsafe. 1. Haifa Group is a world leader in the field of specialty fertilizers. If you’re interested in making a durian perfume, those two are probably a good place to start. "Durian is 10 times more profitable than palm oil," the presenter gushed. Thiram was patented in 1934 by William Tisdale, who was the Chief Pathologist for Bayer. The EPA Fact Sheet describes all three as “non-toxic” to humans, other mammals and birds, yet also notes that Carbendazim causes birth defect and infertility. It’s always good to hear from a grower’s perspective. Durian lovers in Singapore can eat the pungent fruit without fear, as the Agri-Food and Veterinary Authority has dispelled rumours that suggested … Sulfur doubles as a non-toxic pesticide and fungicide often used in organic farming for treating powdery mildews and mites, just like people use sulfur soaps for treating skin conditions like athlete’s foot, acne, and even the horror that is scabies. Durian (Durio zibethinusMurr.) Chemicals also account for the enticing smells (and thus much of the taste) of foods. If we need more nitrogen we apply aged chicken manure, etc. But from what I can gather, the different names/types of surfactants depend on whether or not the part of molecule that wants to bond with water (the hydrophilic side) is carrying a positive or negative charge.
