S-methoprene Active Ingredient Molecule


(S)-Methoprene is an insect growth regulator. Rather than killing insects, it controls them by interfering with normal hormone levels within the insect at critical development periods preventing growth and/or maturation. It is active by contact or ingestion and in some insects (e.g., fleas) it affects eggs or female fecundity. (S)-Methoprene controls a broad range of insects including diptera, hymenoptera, coleoptera, homoptera and syphonaptera. Use patterns include post-harvest grain protection, mosquito larvae control, as a preventative of flea-egg development and as a feed-through for the control of horn fly larvae in cattle manure. In the U.S., (S)-methoprene has been exempted from food tolerances by the EPA.
Piperonyl Butoxide Active Ingredient Molecule

Piperonyl Butoxide

Piperonyl Butoxide, or PBO, is a synergist. It inhibits mixed function oxidases (MFO) of the insect so that its natural detoxification system is blocked and the efficacy of applied insecticides is increased. PBO is used mainly to synergize sodium channel modulators such as pyrethrum and pyrethroids. PBO is arguably the most used synergist in the market today.
Pyrethrins Active Ingredient Molecule


The Pyrethrins story is one of a simple daisy with rare natural properties (nature’s own insecticide). Pyrethrins are actually a mix of three naturally-occurring closely-related insecticidal compounds extracted from chrysanthemum flowers, Pyrethrins I, and the 3 corresponding esters of pyrethrin acid. In the U.S.A., this mix is standardized as 50 plus or minus 2%. These compounds disrupt sodium channels in the neurons of insects causing knockdown and death, with some acarycidal activity. It is used to control a wide spectrum of insects and mites in public health, stored products, animal housing, and on domestic and farm animals.
