This is gonna be my last post on the topic because it’s not worth the argument. The only reason I even posted anything is because it blows my mind that neem gets such a bad wrap. People clearly don’t understand the difference between neem and a azadirachtin extract product. I blame that on misinformation.
Since there clearly using a azadirachtin concentrate and not a natural neem product such as oil or meal in the study you posted related to the graph, I don’t even wanna go through the trouble to get the study because it’s not going to prove anything except what I already suspected. azadirachtin concentrates can be toxic, neem is not when used properly.
Your quoting a study you never even saw, just because you saw a graph which could have meant anything. And just as I suspected , there using a azadirachtin concentrate in the study related to that graph. Your also are taking pieces of information from one study adding it to another and saying here’s my sources. Thats not science thats your opinion.
The length of time it takes for neem to break down in soil, which will vary greatly between soils, adding that to the time it takes for “ azadirachtin “ to leave leaf tissue when using a drench from a “ extract” and saying it’s logical to think that will be the amount of time residual azadirachtin stays in a plant from using neem meal makes no sense. That’s not even close to the same thing and there are lots of other variables there bro.
The other study there using neem meal at rates you would never use in growing cannabis or use in any other gardening applications as a fertilizer and there using different pesticide sprays if I recall as well.
If they used meals and oils in the same manner as any cannabis grower would and still showed concentrations of azadirachtin in the tissues for the length of time as you say, I would not say another word on the topic but they don’t.
My position is this and I’m not going to comment again. If you use neem meal in your soils and use oils correctly, azadirachtin will not be in your end product.
People using azadirachtin concentrates and using them at inappropriate times , is why neem is getting a bad wrap in the cannabis community, particularly those making cannabis extracts which adds another variable. in reality , if your using a azadirachtin extract, it’s not neem at all at that point. Neem is wonderful for your soil when used according to the directions and there isn’t a study out proving otherwise.
I demanded the said study from the canadian forest service, they emailed me a pdf of the study. They made clear in the email that there is a copyright issue and it is illegal to publish this or share it anywhere. The graph is in the study.
Plus the study itself references to many other studies which proves the efficacy of soil drench with azadirachtin against sucking pests.
The methodology is there too. They used a 20% azadirachtin solution for the experiment.
You can type your mail into the canadian forest service and get the study yourself. I dont want to go into a copyright problem here.
But there is an important part about the population densities with the treated plants and the control plants.
This is very important!
They noted a 83% decrease in the population density of spider mites on the treated plants by the 10th day in comparison to the untreated plants. Gradually rising from 3% percent at the first day of application.
83% with that measly ug/g values.
