Pymetrozine is a member of the class of 1,2,4-triazines that is 4,5-dihydro-1,2,4-triazin-3(2H)-one substituted by a methyl group at position 6 and a (pyridin-3-ylmethylidene)amino group at position 4. It has a role as an antifeedant, an environmental contaminant, a xenobiotic and a TRPV channel modulator. It is a member of 1,2,4-triazines and a member of pyridines
Pymetrozine is an organophosphate alternative and has potential for utility in both integrated pest management (IPM) and resistance management programs because of its unique mode of action, its selectivity, and its safety to predators, parasites, and other beneficial mites and insects. Pymetrozine poses minimal risk to birds, bees, fish and aquatic invertebrates. The pymetrozine environmental fate profile indicates no major issues in the areas of soil mobility and fish bioaccumulation. Pymetrozine is not acutely toxic and is not a mutagen, neurotoxin or a teratogen. The labeled uses of Fulfill Insecticide and Endeavor Insecticide do not appear to pose a significant risk to workers or the general public
Nitenpyram is a chemical frequently used as an insecticide in agriculture and veterinary medicine. The compound is an insect neurotoxin belonging to the class of neonicotinoids which works by blocking neural signaling of the central nervous system. It does so by binding irreversibly to the nicotinic acetylcholine receptor (nACHr) causing a stop of the flow of ions in the postsynaptic membrane of neurons leading to paralysis and death. Nitenpyram is highly selective towards the variation of the nACHr which insects possess, and has seen extensive use in targeted, insecticide applications.
Known under the codename TI 304 during field testing starting in 1989, the compound's first documented commercial use was in 1995 under the name "Bestguard" as an agricultural insecticide. Later, nitenpyram was expanded for use as a flea treatment by the Novartis company under the trade name "Capstar", with a subsequent FDA approval for non-food producing animals in October 2000. The current producer of nitenpyram itself is the Sumitomo chemical company. Nitenpyram continues to be used commercially, though data from market surveys indicate a significant decrease in the global usage compared to other insecticides or neonicotinoids.
Due to its use as an insecticide and treatment of non-food producing animals, it was not deemed necessary to research the human toxicology during its main use, and, as such, not much is known about the details of nitenpyram's effects on humans. Looking at rat experiments however, the lethal amount of nitenpyram is quite high (on the order of grams) in mammals in general, whereas invertebrates will die with only micro or nanograms of the substance.
Neonicotinoids, in general, have a low degradation rate when used for agricultural purposes, which allows for long-lasting protection of the crops against plant-sucking insects and indirectly the plant diseases these insects might carry.
|Formulation type||Pymetrozine 60%+Nitenpyram 20%WDG|
|Mode of Action||
Pymetrozine 60%+Nitenpyram 20%WDG attacks the nerve system of insects and mites, causing paralysis within hours. The paralysis can not be reversed. This is active once eaten (stomach poison) although there is some contact activity. Maximum
mortality occurs in 3-4 days.
