seems to be a lot of mis information aout here about azadirachtin.
Azadirachtin is the active ingredient in
Neem Oil and products like
Azamax and Azatrol. It is considered non-toxic to humans and has been used as an herbal remedy for ailments for centuries in India and the middle east.. Like a certain other plant extract we are familiar with.
Shoots of the Neem plant are eaten as food in India. It is absolutely not in the same class as products like Abemectin (
Avid) or Bifenazate (
Floramite) which are highly toxic.
Floramite has been proven to cause liver cancer for instance. Safety measures should be taken when applying these products and the label should be followed to the letter. If you mis-apply these products and someone gets sick you are legally responsible.
THE LABEL IS THE LAW!
You can apply these Neem extract products as the label suggests, but it will in most likelihood impact the flavor of your finished herb in a negative way if you use them right up until harvest.. It can also turn pistils red early which can increase your chance of a fugal infection.
If you must use the product late into flower it is best to discontinue use at least a week before final flush. The plant and your lights should completely break the chemical down or metabolize it in 10-14 days.
People suggesting products like
Eagle 20,
Avid, and
Floramite need to understand that those products require an applicators license in many states. If you don't have one, possession of them is illegal. If you mis-apply these products and someone gets sick from your herb you are legally responsible for a crime which in an extreme instance could be considered attempted manslaughter or worse.
I am a former exterminator. I am telling you
Azamax and Azatrol are very safe to use as long as you follow the directions on the bottle. If you are unfamiliar with how to properly apply pesticides I would stay away from the heavy products like Abemectin.
Avid might not kill you tomorrow, but it can cause you a lot of serious health problems down the road. Full respirators with a vapor filter should be worn during application as well as goggles, a hat, long sleeves, gloves, shoes, and long pants. Once you are done applying the product CHANGE CLOTHES. They are good products if you have a very heavy infestation that isn't responding to anything else. They absolutely work, but they come with some risk. The best time to apply them is ONCE very early in veg as a preventative, and only if you have a history of serious bug problems. If you spot a couple of mites don't freak out and start nuking your plants, your grow room, and yourself with heavy toxic chemicals. Stick with Neem derived products and
pyrethrins and rotate them every 4-5 days with something like
Mighty Wash or Purespray.
READ THE LABELS and follow them to the letter.
