bayer advanced shouldn't be used past early veg IMO (it is systemic .... do you want to be smoking that shit?) DE can and should be used at all stages, it will keep crawlers/fliers down a bit + it feeds extra minerals to the roots as you water it in and it breaks down (just wear proper mask/gear when applying so you don't breath it in). you might also want to try a 5%
pyrethrin drowning (this partially worked for me. but the met52 was what did it long term)
I cannot say this enough: research, research, research. too many people get lazy and don't research the product they are buying. if anyone is going to consume/smoke/injest the end product, then as a grower, we MUST do proper due diligence on the products we put into and on our lovely girls. every product has a data sheet with information that you need to know. it's science, not word of mouth "this helped me".
Pesticides can be classified based upon their biological mechanism function or application method. Most pesticides work by poisoning pests. A
systemic pesticide moves inside a plant following absorption by the plant. With insecticides and most fungicides, this movement is usually upward (through the xylem) and outward. Increased efficiency may be a result. Systemic insecticides, which poison pollen and nectar in the flowers, may kill bees and other needed pollinators.
