Description
Technical field
The present invention relates to a kind of pesticidal preparations, be specifically related to a kind of efficient miticide being main active with diafenthiuron and pyrethrin.
Background technology
Phytophagous evil demodicid mite due to its breeding cycle short, individual little, grow fast, reproductive capacity strong and is easily generated the basic bionomic strategies such as Drug resistance so that it is become and be difficult to one of harmful organism of preventing and treating.
Diafenthiuron chemical name is [1-tertiary butyl-3-(2,6-diisopropyl-4-Phenoxyphenyl) thiourea], its commodity are called methamidophos, boccaccio, are the new sulfur ureas Insecticidal and acaricidal agents of a kind of brand-new chemical constitution, have tag, stomach toxicity, interior suction and fumigation action. Diafenthiuron need under ultraviolet radiation or in polypide under the effect of mixed-functional oxidase, it is decomposed into carbodiimide derivative and just there is biological activity, carbodiimides can optionally the Fo-ATP enzyme of covalent bond mitochondrial inner membrane and Outer membrane protein and suppress mitochondrial respiratory effect, hinder the performance of neurocyte mitochondrial function in pest body, affect its Repiration and energy conversion, so that insect is ossified. The selectivity of target organisms is depended primarily on the conservative of body Mitochondria by diafenthiuron, therefore to mammal low toxicity, but be high poison to the aquatile such as Brachydanio rerio, astacus, to Apis and natural enemy insect non-selectivity.
Pyrethrin includes pyrethrin I, pyrethrin II, cineraria element I, cineraria element II, jasmine centautin I and jasmine centautin II composition. Pyrethrin directly acts on excitable membrane, the ionic conduction of interference film, the neurilemmal sodium channel of major effect, makes the disappearance process that the conduction of excitation time sodium increases delay, causes cross-film sodium ion stream to extend, cause Sensory nerve fibre and nervus motorius axle repeatedly movable, of short duration neuronal depolarization and lasting muscle contraction, thus playing paralysis insecticide nervus centralis effect, for killing insects by touching agent, good disinsection effect, action of contace poison is extremely strong, insecticide is not likely to produce Drug resistance. Natural see that light slowly decomposes except centautin, noresidue after therefore using with the pesticide of its preparation or hygienic insecticide etc., and people and animals are had no side effect, to plant and Environmental security, it is internationally recognized safest pollution-free natural insecticide. But the light stability of natural pyrethrum is poor, causing its lasting period short, natural pyrethrum is by separating and extracting in pyrethrum flowers simultaneously, and its cost is of a relatively high.
But the preventing and treating of life-time service diafenthiuron and pyrethrin, the Drug resistance making evil demodicid mite increases the weight of day by day, cause that control of pest mite dosage is big, cost is high, weak effect, environmental pollution are serious etc., therefore necessary on the basis of prior art, the prevention effect that research and development make new advances is excellent, the novel acaricide that evil demodicid mite Drug resistance is low.
Summary of the invention
Goal of the invention: the invention aims to solve the deficiencies in the prior art, it is provided that a kind of miticidal effect is excellent, and evil demodicid mite Drug resistance is low, stable in properties, the Compositional acaricide containing diafenthiuron Yu pyrethrin that cost is low.
