Camilo Diaz Posted March 26, 2018 Share Posted March 26, 2018 I remember some news about the Thai coconuts exports being banned in many country because of high pesticides and quimics content, I see pick ups selling them cheaper everyday around and i wonder if better to avoid them? Does anybody has any concrete knowledge about it? Link to comment Share on other sites More sharing options...
Formaleins Posted March 27, 2018 Share Posted March 27, 2018 Not sure about a ban on Thai coconut exports, but there probably are NO exports. Thailand has been hit by an insect problem that is destroying its coconut plants. Thailand is now actually having to import coconuts, so there won't be much in the way of export.

uffe123 Posted March 27, 2018 Share Posted March 27, 2018 I see plenty of coconuts in my village, no one is even bothering to take them off the trees. Have several trees in my yard and full of coconuts, no one bothers to get them off the trees, i guess at 5 bath a coconut its not worth the effort. Dont know of any bug problem or use of pesticides. Maybe in the bigger plantations in the south. Link to comment Share on other sites More sharing options...
drtreelove Posted March 27, 2018 Share Posted March 27, 2018 Sr Diaz, I was puzzled by the term "quimics", until I saw the Spanish surname, and realized that you may be using the Spanish pheonetic for what Thai people call "chemi" , pui chemi is chemical fertilizer. I am not up on the current status of the Thai coconut industry, exports or regional pest infestations and chemical pesticide use. But I do know that coconut palms, wherever they grow, have a number of pest and disease issues possible. Which specific pest or pests is prevalent varies with the geographical area. Pest control methods and materials are many, one of which is stem injection of a systemic insecticide, which may or may not end up in the edible part of the nut. The coconut palm pest infestations that I have encountered in Thailand are primarily coconut rhinoceros beetle, often associated with red palm weevil infestation at the same time. These pests commonly go to ornamental palms also. And then in some regions there is coconut hispine (or hispid) beetle. Other countries are battling massive coconut scale insect pest infestations, caterpillars, and fungal disease issues. I'm not sure what all is here in Thailand at this time. Chemical fertilizers would not likely be a direct issue for food toxicity. Non-systemic contact and barrier pesticides would normally not enter the plant tissues and edibles, the hazard with these is primarily for the applicator and for damage to beneficials, natural pest predators. Pyrethroids, like cypermethrin, is the barrier spray of choice for some growers, and is less toxic for the applicator and environment than some older generation insecticides that I have seen recommended in Thailand, like chlorpyrifos, an OP. There are biological and cultural controls available for most beetle pests, for conscientious growers and communities. Systemic insecticides, usually organo-phosphates or newer generation neonicotinoids, if not closely regulated, are often used without due consideration of possible food contamination. There has been conflicting information and scientific research on this subject. But if pesticide residues are being found in the edible parts, then restrictions on imports/exports would certainly be warranted. Whether or not you should eat local coconuts from the market or roadside sales? I do. I really doubt that most local growers are using systemics insecticides, due to cost. Here's an example from the Philippines of one particular pest issue, and a controversial injectable systemic insecticide being used. https://www.scidev.net/asia-pacific/environment/news/use-of-chemical-versus-coconut-pest-stirs-hornet-s-nest.html Link to comment Share on other sites More sharing options...

My wife and I were in Chumphon and watching a couple of monkeys harvesting coconuts. I was taking pictures when one of them stops dead and looks me straight in the eye, then flips me off; yeah a monkey giving me the finger. What kind of training is that.

mike324 Posted March 27, 2018 Share Posted March 27, 2018 Peeled coconuts may have chemicals because people do dipped them in chemicals to make the skin look white and fresh for export or to be sold in supermarkets. But the ones sold on streets that are freshly peeled don't have those preserving chemicals. Pesticides do leached into coconuts from the tree but its still a very low level, but very few pesticides actually touch the coconut itself, so coconuts in general are pretty safe.

islandguy Posted March 27, 2018 Share Posted March 27, 2018 Living around lots of coconut groves, I hardly ever see any spraying of the trees. There is some spraying by growers and government agencies at the crown of the trees for the insect infestations that have taken quite a toll of the industry, but spraying for maintenance and prevention seems little done. These are all mature groves and it seems they mostly just harvest the nuts. There were a lot of trees in my area last year with orange tape around the trunks after government sponsored spraying, didn’t see any harvesting of those trees (and I hope none was done!) What is common is spraying herbicide to kill weeds on the ground, although cutting with weed whippers is also often done instead. Link to comment Share on other sites More sharing options...

I first didn't take this article too seriously, but then I noticed the link at the bottom to the parent article and video. They are using a crude stem injection technique to treat coconut palms with a highly mobile insecticide that could very well end up in the coconuts, water and flesh. It is completely irresponsible and without concern for consumers. I don't know how prevalent or widespread this is, but I wouldn't even wish it on my rude monkey to drink that coconut water. http://www.bangkokbiznews.com/news/detail/784172 Link to comment Share on other sites More sharing options...
drtreelove Posted March 27, 2018 Share Posted March 27, 2018 I got a little more information. This is a program to combat an infestation of coconut black headed caterpillar. (the larva stage of a moth). They are developing an IPM program with several modalities and materials as possibilities, including biological control agents and certain insecticides. The stem injection method is only one of the trial methods, and the material being used is emamectin benzoate, a derivative of abamectin. I've used it in closed system stem injection for certain tree pests in the US, but it's always labeled: "Do not apply to trees that may yield food consumed by humans or used in animal feed." The IPM project in the video is from Samut Songkhram. http://www.agriqua.doae.go.th/blackheadcontrol/blackhead.html https://www.matichon.co.th/news/601307 Link to comment Share on other sites More sharing options...

janclaes47 Posted March 27, 2018 Share Posted March 27, 2018 All coconut trees surrounding my house have since more than a month an orange sticker with the date written on it. I asked my son and he told me that the trees have been injected with a chemical. It must be government initiated since the land belongs to many different owners. Yet they have been harvesting the coconuts without any hesitation. Link to comment Share on other sites More sharing options...
elgenon Posted March 28, 2018 Share Posted March 28, 2018 They sell young coconuts from Thailand at Sprouts markets in California. $2.95 I think. Sometimes 2 for $5. Do they fly them or transport by ship? Link to comment Share on other sites More sharing options...
