Description

A kind of disinsection prophylaxis poison composition based on malicious fluorine phosphorus and insecticide

Technical field

The present invention relates to agriculture chemical compounding compositions field, particularly a kind of composition pesticide containing poisonous fluorine phosphorus and insecticide, the virus disease that is mainly used in preventing and treating various crops, and the preparation of the various formulations of said composition and application technology.

Background technology

Virus disease is a class disease very rambunctious in plant disease, various crop virosis presents serious development trend in recent years, except tobacco mosaic, cucumber mosaic and tomato virus disease that tradition comparatively generally occurs, the morbidity of some diseases is exponential increase, as withered in rice stripe leaf, rice black-streaked dwarf, southern rice black-streaked dwarf.The cause of the popular harm of virus disease mainly comes from medium insect as insect propagation such as aphid, plant hopper, aleyrodids, 621 kinds, whole world known plants virus, what the insect of take was mediator is 272 kinds, and aphid, plant hopper are considered to propagate the primary vector insect of the viroses of plant.

Virus Diseases of Rice is the important disease that is distributed widely in Ge Dao district, the world, the Virus Diseases of Rice that at present China occurs mainly comprises black streak dwarf, southern rice black-streaked dwarf disease, stripe virus disease, the common disease of stunting, yellow dwarf, orange leaf disease, bunch short disease, tingia stunt disease, the short disease of knurl, careless shape dwarfing etc., in the eighties after latter stage, black streak dwarf and stripe virus disease evil swash acute rising, and the southern rice black-streaked dwarf of a large amount of outbursts is in recent years sick, in some rice district, cause crushing harm.The susceptible rice strain of paddy rice is obviously stunt, and mostly can not ear, and the incidence of disease is close to production loss rate conventionally, and the field of serious morbidity can lead to total crop failure.Rice seedling is more susceptible to tillering stage, and after jointing, resistance increases day by day.Rice field previous crops is planted susceptible host crop, and weeds in field is grown thickly, single, double season companion planting, early, middle and late ripe kind transplanting, early sowing early rice, single this thin planting, favourable rice field ecological condition is caused to the accumulation in infection insect and malicious source in capital, thereby is conducive to the generation of disease and popular.

Winter-Spring is warm, and paddy growth early stage, high-temperature drying, was conducive to pass during overwinter generation and rice growth existence and the activity of virus mediator, promoted viral propagation and spread.The Virus Diseases of Rice that the whole world is reported at present, the overwhelming majority passes poison by plant hopper or leafhopper amboceptor in persistence mode, owing to passing murder by poisoning worm, there is the property of migrating, therefore, the distribution of Virus Diseases of Rice has certain provincialism, there is harm and there is " intermittence " feature, increased the difficulty of prevention and cure of disease.Can find out, the onset condition that affects Virus Diseases of Rice is a lot, and wherein a topmost factor is vector insect.

The virus disease occurring on tobacco comprises tobacco mosaic virus (tmv) (TMV) and cucumber mosaic (CMV).TMV can survive the winter in various plants, soil compaction, and drought, the plot morbidity that field nematode is caused harm heavier is heavy.The slight friction of sick strong leaf causes microtrauma mouth, and virus can be invaded, after intrusion, in parenchyma cell, breed, after enter the whole strain of vascular bundle tissue infection.Tobacco mosaic virus (tmv) mainly occurs in Qi Zhi land for growing field crops, seedbed squaring period.Continuous cropping or malicious source is increased with solanaceous crops interplanting, the incidence of disease and occurring degree obviously increase.Between disease, healthy tree, contact touches, and uses not decomposed manure, and training is with virulent soil all can increase the weight of viral communication.Tobacco mosaic generally occurs in Ge Yan district, the world.All there is generation in cigarette district, China north and south, especially Main Tobacco-growing Regions In South be injured heavier, the general 5%-20% of the field strain incidence of disease that all can fall ill from seedling stage to harvest time, indivedual fields can be up to 90%-100%; The loss of early stage morbidity can reach 50-70%, even total crop failure.In addition, sick leaf is irregular colour after roasting solarization, and smoke is poor, and quality greatly reduces.Cucumber mosaic can be propagated by aphid and friction, and vega be take cigarette aphid, cotten aphid as main.CMV can not survive the winter on invalid body, mainly on winter hard vegetable, perennial trees and farmland weed, survives the winter, and the next spring is migrated and passed in cigarette strain by alatae.Cigarette strain prosperous long stage before buddingging is more susceptible, and after buddingging, premunition strengthens.The vega adjacent with the vegetables such as cucumber, tomato, pimento, when aphid is more, morbidity is heavy.Land for growing field crops aphid enters behind the peak of migrating about 10 days, starts to occur onset peak.
