Hi farm,
I was recently reading up on insecticides, for fun :) and i realized, most of us have, to a degree, the wrong idea about neem oil and neem based products. We usually use the terms interchangeably as i noticed and don’t really realize or underline that they’re not the same thing and some of us rather use neem oil than an extract of it because, it feels more organic. Now without copy and paste i’ll say these.
1. Neem oil and insecticides that are derivative of “NeemAzal Technical” are in no way the same thing. First of all we have to address that Azamax is just “NeemAzal Technical” diluted and bottled by GH. This is on the product description on GH site. What is NeemAzal Technical? NeemAzal Technical is the result of a colloboration between Trifolio Gmbh of Germany and Parrys of India. NeemAzal Technical is a water based extract of neem seeds, which is designed to leave the oil behind and extract only the active ingredients. These ingredients include azadirachtin A-L, other azadirachtins and azadirachtinin. These compounds belong to the chemical group of “tetranortriterpenoids”. Just rolls of the tongue :D lets just call them limonoids :) are considered safe for mammals and benefical insects.
2. The water extraction and resulting seperation of oil to create NeemAzal Technical is a choice, rather than an unevitable drawback of trying to extract the most out these seeds. This choice was made to increase the safety of the end product. Neem oil itself contains a compound called Aflatoxin. This compound does serious damage to mammals, mainly to the liver. So this water based extraction process, while extracting most of the insecticidal compounds, tetratriterpenoids, leaves the oil itself behind. So the end product is pure as it can be.
3. Then NeemAzal Technical gets mixed with organic vegetable oil that is free of aflatoxin. And voila, you have Neemazal T/S or other derivatives like Azamax. These products are one of the safest insecticides you can use on your plants and can even be used in flowering, tho not ideal (partly because of the vegetable oil used to dilute the product). This is a delicate subject for most, i’m aware, and from all my research, i came to the conclusion that, azadirachtin based products can be sprayed a month prior to harvest and the end product would be free of azadirachtin. Also should be noted that NeemAzal T/S MSDS, environmental fate and withholding period datas suggest that it can be used 3 days prior to harvest. My one month safe period is based upon another related research conducted for Canadian Forest Services. In anycase my opinion is that the best way, is taking precautions rather than going into battle, facing your problems early on, in veg.
-Also it should not go unnoticed that the said study done for Canadian Forest Services; Uptake, translocation, persistence and fate of azadirachtin in aspen plants (Populus tremuloides Michx.) and its effect on pestiferous two-spotted spider mite (Tetranychus urticae Koch), definitively concludes that the azadirachtin compounds are taken in by the roots and gets deposited in the plant tissue (roots, leaves, stems in the order concentration in ug). Thus, a soil drench for application of NeemAzal is not a bad idea either. At this type of application however, the azadirachtin in the leaves linger more than 50 days, albeit in residual amounts so, the application time should be decided taking this into account-
So all in all, whether you’re battling with an infestation or just implementing your IPM schedule, its better to go with NeemAzal or a derivative of it, rather than neem oil which contains Aflatoxin or another neem extract made by using chemicals to get higher concentrations.
I wanted to share these with you good people because, CrimsonEcho cares about your health :D. If you have any researches or anything to add to further this thread, you’re welcome to contribute and if you have any objections to what i presented here, you can do that too :)
Happy growing.
