Abstract
The invention belongs to the field of pesticides and particularly relates to an insecticidal composition for preventing and treating rice hoverflies. The effective components of the insecticidal composition provided by the invention comprise: nitenpyram and clothianidin. The effective components, namely nitenpyram and clothianidin, of the composition provided by the invention are mutually matched without conflict and have a good synergistic effect within a certain range, the prevention effect is higher than that of a single agent, and the pesticide effect is relatively durable; the insecticidal composition reduces the drug resistance, reduces the repeated use times of the pesticide, reduces the use amount of the pesticides and lowers the application cost of the pesticides; the composition provided by the invention has a special effect on insect pests such as hoverfly. Since the residual quantity of the insecticidal composition is relatively low, the insecticidal composition is relatively easy to decompose after the lasting period and relatively environmentally-friendly, and has the relatively great significance on increasing both production and income in agricultural areas.
Description
Technical field
The invention belongs to pesticide field, being specifically related to a kind of Pesticidal combination for preventing and treating paddy rice syrphus fly.
background technology
Syrphus fly, becomes polypide small-sized to large-scale.Body is wide or very thin, the speckle of the single dead color of body colour or the bright colors such as normal tool is yellow, orange, greyish white, and some kind then has the metallochromes such as indigo plant, green, copper, and outward appearance is honeybee seemingly.Head is large.Male eye symphysis, female life of having hallucinations, also has both sexes all from life.Syrphus fly (Scaeva pyrastri) ovum generally produce in aphid group for white, microscler, the netted decoration of chorion tool.
Nitenpyram, mainly act on insect nerve, similar to other anabasine compound.Clothianidin there is the insecticidal activity of wide spectrum and the lasting period long.Application dosage is 150 ~ 400 grams of active ingredient/hectares.
The synthetic method of clothianidin is: take phenol as initiation material, and first etherificate obtains phenetole, again bromination and obtained Grignard reagent, obtains trifluoroacetophenone with trifluoroacetic acid anhydride reactant; Then generate with Ethylene Oxide reagent reacting the expoxy propane replaced, and react with benzylalcohol; Object clothianidin is obtained finally by chlorination, reduction dechlorination.Clothianidin english common name: Clothianidin chemical structural type: anabasine chemical molecular formula: C6H8ClN5O2S applies: wide spectrum, systemic insecticide, be mainly used in paddy rice, vegetables, fruit tree and other crop, control Semiptera, coleoptera, diptera and some lepidoptera pest.Anabasine compound is the novel pesticide of a class highly effective and safe, high selectivity, and its effect is similar with nAChR, have tag, stomach toxicity and systemic activity.Anabasine has become a class chemical insecticide with fastest developing speed, due to they have that insecticidal spectrum is wide, consumption is low, interior suction and plant is conducted, mechanism of action novel and Environmental compatibility advanced chemical biological nature.It is made to obtain larger success.
