Understanding Miticides

[dagnabit]

As a result, Thailand has banned the use of two insecticides in rice--Abamectin (hello, Avid!) and Cypermethrin (I'm guessing it's another generation of pyrethroids). Why? Because, they're known to be MAJOR CAUSES of planthopper outbreaks.

How's that grab ya? Been waiting to share this with those who love telling folks to use shit like Avid.

gawd forbid a leafhopper outbreak in my grow room

Since Abamectin is a natural product derived from soil bacteria , reckon it should be considered organic , has approval for lettuce and other food crops and a very short half life under lights.

Cypermethrin is a more persistant analogue of the natural pyrethrins from chrysanthenums , used extensively on strawberries here , not as scary as most on that list , not approved for mites but will kill all motile stages a few days before introduceing predators with good effect.

The mode of action pdf is well worth a read.

Urea, neonicotinoids, and pyrethroids are all 'derived' from natural biota too, yet all are prohibited in organic/bio farming, and for good reasons. Abermectin is biosythesized and should not be considered "organic".

very true foomar.
Ive read that about avid,
actually avid is approved for over 100 food crops world wide.
like it, know it or not everyone of us here is currently eating a food crop that has been treated with avid.


AVID, i use it and forbid 4F (spiromesifen), floromite.
and less toxic pesticides like volck oil.
there is nothing wrong at all using this products if done so correctly and responsibly,
just like anything else including natural controls that can and have caused serious damage if not thought out in a responsible manner.

if you don't like them fine,
but to demonize them is wrong and narrow minded any more than one would demonize some of the toxic chemicals and natural products that are used in creating life saving vaccines and quality of life enhancing drugs.

Fair enough, and it seems completely reasonable for conventional food crops or tobacco...or even "recreational grade" cannabis products.

However I think "medical grade" cannabis is a different beast all together and, as such, should be produced at a much higher standard. The very term "Medical Grade" connotes that a substance is pure, unadulterated, and of the highest possible quality. While these synthetic products can be used responsibly and correctly, they still leave residues at levels probably inappropriate for a medical grade product, especially in concentrated forms.

That said, I don't think that most folks realize that any production standards for the "production of marijuana" are not applicable to your mother plants. The "production of marijuana" begins the moment a clone is cut or a seed is wetted. Everything upstream is not considered part of the production cycle of a crop product and can be treated very differently. This is true for every crop in the world produced via clones. I find that simply keeping the mothers 100% pest free keeps pest pressure very low throughout the production process, even with thousands of plants in an enclosed facility.
