Description
Technical field
The present invention relates to the agriculture chemical compounding technical field, be specifically related to a kind of ethyl pleocidin and composite Pesticidal combination of chrysanthemum ester type compound of containing.
Background technology
Ethyl pleocidin, Spinetoram (XDE-175) are by the plain insecticides of many desinsections of a kind of novelty of Dow AgroSciences's exploitation, are the plain second generation product of many desinsections.Many desinsections element is the antibiotic insecticide that is produced by the fermentation of actinomycetes thorn saccharopolyspora strain; Form by spinosyn A and spinosyn D; Cause is with the safety of biopesticide and the quick-acting of chemical synthetic pesticide; Obtained U.S.'s " presidential green chemical challenge prize " in 1999, and beginning is registered above on 100 kinds of crops in 24 countries in this year.Though but this medicament is unsatisfactory to the insect pest control of crops such as fruit and nut to the good disinsection effect of vegetable crop.And the successful solution of ethyl pleocidin this problem, especially the pomaceous fruit heart-eating worm apple olethreutid that can not prevent and treat many desinsections element has special efficacy, its insecticidal spectrum is wider than the desinsection of manying element simultaneously.Advantages such as in addition, it also has main useful insect influence littler, and the unit are consumption is lower, and residual life is short in environment obtain 2008 " US President's green chemical challenge general ".Its composition structural formula is:
Ethyl pleocidin is spinosyn J and the spinosyn L desinsection chlorins compound more than two kinds that is produced by fermentation, in the presence of catalyzer, reactant and solvent, and the novel pesticide that the process chemical modification finally obtains.Its mechanism of action is different from traditional organic phosphor and pyrethroid insecticides acts on acetylcholinesterase and Na
+Passage, it is to act on nAChR, and is also variant with nicotinic insecticides such as Imidacloprids.It can be applied to fruit, nut, grape vine, cereal, soybean and greengrocery crop at present.Not only effective to fruit such as Lepidoptera, diptera, coleoptera, thrips and Homoptera, vegetable-crop pest-insect; And to preventing and treating the pest efficient of standard fruit-tree and nut etc.; Aspect insecticidal activity, it is plain that the insecticidal activity that ethyl pleocidin is selected various common economic crops insect pests such as tikka, beet armyworm, cabbage looper, sweet potato whitefly, leaf roller and cotton bollworm to tobacco budworm, cotten aphid, two is higher than many desinsections far away.
Beta-cypermethrin (beta cypermethrin) is an agricultural fungicides, has and tags and stomach poison function, has destroyed neural function through interacting with the insect sodium channel.The lepidoptera pest that takes place on the main control crops has strong toxicity.
Gamma cyhalothrin (Lambda-cyhalothrin); Have tag, stomach poison function; Through suppressing the conduction at insect neural axon position, insect is had the effect of walking quickly and keeping away, knocking down and killing, insecticidal spectrum is wide; Active higher; Drug effect is rapid, sprays the back resistance of rainwater washing against, but long-term the use is prone to it is produced resistance; Insect and evil mite to sucking mouth parts have certain preventive effect, are applicable to the insect of peanut, soybean, cotton, fruit tree, vegetables.
Biphenthrin (Bifenthrin) is a kind of pyrethroid Insecticidal and acaricidal agent.Have tag, stomach poison function, do not inhale in not having, fumigation action, insecticidal spectrum is wide, effect rapidly.In soil, do not move, safer to environment, be applicable to and prevent and treat insects such as lepidopterous larvae, aleyrodid, aphid, leaf miner, leafhopper, tetranychid on the crops such as wheat, cotton, fruit tree, vegetables, tealeaves that be used for worm, when mite is concurrent, province's medicine saves time.But in actual mechanical process, use the agent of Biphenthrin list separately, insect is prone to produce resistance.
