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.
Diflubenzuron Active Ingredient Molecule


Diflubenzuron is a chitin synthesis inhibitor, which is another type of insect growth regulator. The chitin synthesis inhibitors interfere with the normal synthesis of insect exoskeletons during molting or at hatching of eggs. Diflubenzuron is a non-systemic active ingredient with contact and stomach activity. It is used to control a wide range of leaf-eating insects in forestry, woody ornamentals and fruit. It controls some major pests in cotton, soy beans, citrus, tea, vegetables, rice, peanuts, tree nuts and mushrooms. Diflubenzuron also controls larvae of flies, mosquitoes, grasshoppers and migratory locusts. Due to its selectivity and rapid degradation, as well as high solubility in water and soil, diflubenzuron is less harmful to beneficial insects and thus a good candidate for integrated pest management (IPM) programs.
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.
Etofenprox Active Ingredient Molecule


Etofenprox is a very effective, low toxicity pyrethroid that acts on the nervous system of insects by disrupting their neuron sodium channels. Etofenprox is a contact-kill adulticide used to control a wide variety of insects including weevils, beetles, aphids, moths, whiteflies, thrips, borers, fleas and mosquitoes. Etofenprox is well tolerated by mammals, including cats, and is environmentally friendly.
S-hydroprene Active Ingredient Molecule


(S)-Hydroprene is another insect growth regulator that controls insects 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., roaches) it affects eggs or female fecundity. (S)-Hydroprene is mainly used to control insects such as cockroaches, stored product pests, fruit flies, drain flies and bed bugs in buildings and commercial food and non-food establishments.
Tau-fluvalinate Active Ingredient Molecule


Tau-fluvalinate is a pyrethroid insecticide/acaricide that acts on the nervous system by disrupting the neuron sodium channels. It has contact and stomach action. Fluvalinate is used to control a wide range of insects including Lepidoptera, aphids, thrips, leafhoppers, spider mites, etc. However, in the U.S. it is only used in segments other than row crop.
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.
