Abstract
The invention discloses an ultra-low volume liquid containing silafluofen and an organophosphorus insecticide, belonging to the field of pesticides. The ultra-low volume liquid comprises the silafluofen and an active constituent (II), which are compounded into an active constituent, and the balance of a surfactant and a solvent; and the active constituent (II) is selected from any one of fenitrothion phosphorus, quinalphos, triazophos, diazinon, phoxim, fenitrothion, profenofos, chlorpyrifos, malathion, and isocarbophos. The ultra-low volume liquid disclosed by the invention is convenient to process, low in cost, good in pesticide effect, long in lasting period, high in coordinated synergism and capable of saving water, and can be used to reduce environment pollution, improve the utilization ratio and application amount of the pesticide.
Description
Technical field
The present invention relates to pesticide field, is the ultra low volume liquids of fluorine silicon chrysanthemum ester and organophosphorus insecticides specifically, mainly by ultra low volume spraying, low-gallonage spraying or ultra low volume electrostatic spray, realizes the effective control to crop pest.
Background technology
At present for easily producing the control of insect of resistance in agricultural, what main way was exploitation and existing kind without between the new composition of cross resistance or existing pesticide species is composite, the former is because required development cost is high, the cycle is long, and the speed that development rate produces less than pest resistance to insecticide far away at present.Therefore, for the different existing pesticide species of the mechanism of action, being mixed is a kind of selection of the best.If reasonable mixture ratio, can produce significant synergistic effect, make field control effect significantly be better than the effect of each single dose.On agricultural insect pests control, usually there is certain defect in the insecticide that contains single-activity composition, continuous several times is used and is not only made insect easily develop immunity to drugs, and easily cause the pollution to food and environment, by rational mixture between pesticide active ingredient, can overcome above shortcoming.The reasonably composite synergistic effect that active ingredient is produced simultaneously, can improve preventive effect, reduce effective ingredient consumption, cost-saving, delay the drug-fast generation of insect, closely can alleviate and even avoid the pollution of agricultural chemicals to food and environment, and the efficient novel pesticide of the low toxicity that the present invention researchs and develops, not only target drug effect is significantly strengthened, and very low on the impact of people, crop, non-target and environment.
Silafluofene chemical name is (4-ethoxyl phenenyl)-[3-(the fluoro-3-phenoxy group-phenyl of 4-) propyl group] dimethylsilane; Molecular formula is C25H29FO2Si, and English name is Silafluofen, and chemical structural formula is:
Silafluofene is siliceous novel organic insecticide, there is stomach toxicity and action of contace poison, without interior suction conduction, active high, stable chemical nature, the speed of knocking down is fast, insecticidal spectrum is wide, termite is shown to good repellent action, family expenses aspect, as termite preventing and controlling agent, dress material insect-proof agent, in agricultural production, can prevent and treat the insects such as plant hopper, leafhopper class, stinkbug class, rice leaf roller, locust.Silafluofene, to mammal and fish low toxicity, can be used safely in paddy field.
In the present invention, the chemical name of the related organophosphorus insecticides of active component II is as follows:
The chemical name that kills snout moth's larva phosphorus is O, O-dimethyl-O-(3-methyl-4-nitrobenzophenone) thiophosphate;
The chemical name of quinalphos is O, O-diethyl-O-(diethquinalphione) thiophosphate;
The chemical name of Hostathion is O, O-diethyl-O-(1-phenyl-1,2,4-triazole-3-group) thiophosphate;
The chemical name of diazinon is O, O-diethyl-O-[6-methyl-2-(1-Methylethyl)-4-pyrimidine radicals] thiophosphate;
The chemical name of phoxim is 0,0-diethyl-0-(benzene acetonitrile ketoxime) thiophosphate;
The chemical name of sumithion is O, O-dimethyl-O-(3-methyl-4-nitrobenzophenone) thiophosphate;
The chemical name of Profenofos is O-ethyl-O-(the bromo-2-chlorphenyl of 4-)-S-propyl dithiocarbamate phosphate;
The chemical name of chlopyrifos is O, O-diethyl-O-(3,5,6-trichloro-2-pyridyl) D2EHDTPA;
The chemical name of malathion is O, O-dimethyl-S-[1,2-bis-(ethoxy carbonyl) ethyl] phosphorodithioate; ;
The chemical name of isocarbophos is O-methyl-O-(2-isopropoxy carboxyl phenyl) thio-phosphamide.
The inventor is by studies have shown that, silafluofene with kill the ultra low volume liquids that the arbitrary pesticide active ingredient in snout moth's larva phosphorus, quinalphos, Hostathion, diazinon, phoxim, sumithion, Profenofos, chlopyrifos, malathion, isocarbophos is re-dubbed target pest had to high synergistic effect.
The solvent that ultra low volume liquids is low by screening volatility, flash-point is high, good to former medicine dissolubility, low to chemical injury of crops, viscosity is low, during dispenser, be not watered, but directly use with ultra low volume sprayer tool, low-gallonage spraying apparatus or ultra low volume electrostatic spray apparatus.Ultra low volume spraying is owing to not containing high volatile volatile composition in droplet, and its size does not have significant change with quality from leave spraying apparatus arrival target process, has reduced and has volatilized with elegant.Droplet is tiny and even, meets " biological best granula " requirement, has significantly improved deposition.Owing to using without being watered, ultra low volume liquids is suitable for water scarcity, damage by disease and insect fulminant large area occurs and the occasion of dispenser on a large scale in the palpus short time, and ultra low volume spraying simultaneously reduces operator's labour intensity greatly.
Summary of the invention
