Neemproduct.Com supplies Neem Azadirachtin. Neemproduct.Com is an ISO 9000 registered unit that offers neem leaf powder, neem oil, neem cake, etc. The Neem Azadirachtin blocks the insect`s production and release of these vital hormones. Azadirachtin may also serve as a feeding deterrent for some insects. Depending on the stage of life-cycle, insect death may not occur for several days. However, upon ingestion of minute quantities, insects become quiescent and stop feeding. Residual insecticidal activity is evident for 7 to 10 days or longer, depending on insect and application rate.
