Description
Technical field
The present invention relates to a kind of insecticides and application thereof, particularly, relate to a kind of fosthiazate insecticides and the application in preparation injection liquid insecticides thereof.
Background technology
Systemic insecticide be at present important, have insecticidal activity wide spectrum, a compounds that interior absorption is strong.Systemic insecticide is absorbed in the entering plant corpus, and in plant corpus, conducts through root, stem, leaf or other position of plant.Contact or get food medicament and being poisoned to death when insect is caused harm plant.Be transmitted to the dose at each position of plant, foot is poisoned to death the insect at this position of harm, and medicament does not hinder growth and development of plant.
Because systemic insecticide has interior suction, conduction in the plant body, therefore, this insecticides has and other insecticide different features; Like desinsection wide spectrum more, selectivity is stronger, can effectively kill and hide or borer pest; Do not receive the influence of rainfall, save time, saving of labor, province's medicine etc.In several low toxic pesticide kinds of applying in recent years, in the agricultural industry, brought into play huge effect.But the control efficiency of this insecticides is relatively poor, and when injection was used, the lethality of insect was generally below 65%.
Summary of the invention
The objective of the invention is provides a kind of new systemic insecticide in order to overcome the defective of existing systemic insecticide control efficiency difference.
Inventor of the present invention is unexpected under study for action to be found, through with the fosthiazate of the certain content active component as insecticides, can improve the control efficiency of the insecticides that obtains greatly, and when injection was used, the lethality of insect can reach more than 90%.Therefore, to achieve these goals, the invention provides a kind of fosthiazate insecticides; Said composition contains active component and solvent; It is characterized in that said active component contains the fosthiazate as main active, said fosthiazate accounts for the 20-100 weight % of active component total amount; Be preferably 30-90 weight %, more preferably 50-60 weight %.
Preferably, said active component also contains at least a systemic insecticide except that fosthiazate.
The weight ratio of fosthiazate and said at least a systemic insecticide except that fosthiazate is preferably 1: 0.12-2.3, more preferably 1: 0.67-1.
Preferably, said at least a systemic insecticide except that fosthiazate is at least a in carbosulfan, Imidacloprid, Acetamiprid, thiophene worm piperazine, Nitenpyram, thiophene worm amine, MTI-446, imidaclothiz, Rynaxypyr, Aphox, chlorophos, isazofos, pirimiphos-methyl, omethoate, orthene, thiophene worm quinoline, butyl pyrimidine phosphorus, fluorine worm nitrile, capillary and the pyrrole aphid ketone; Further be preferably at least a in Imidacloprid, Acetamiprid, thiophene worm piperazine, Rynaxypyr and the thiophene worm quinoline.
Fosthiazate insecticides provided by the invention, interior suction conductivity is strong, and target is strong; Effect rapidly; To longicorn, pine wood nematode, scale insect, armored scale, root-knot nematode etc. live in inside the trunk or underground pest controling effect good, when injection was used, the lethality of insect can reach more than 90%; Not dilute with water, therefore preparation and easy to use in preparation and the use; When injection was used, the medicament effective rate of utilization was high.Adopt optimal way of the present invention, fosthiazate and the composite use of other systemic insecticides have synergistic effect, have not only improved insecticidal activity, and have enlarged the desinsection scope; Delayed drug-fast development; Reduced the consumption of every kind of systemic insecticide, reduced influence environment, safer to people and animals.Fosthiazate insecticides provided by the invention can be widely used in agriculture and forestry desinsection fields such as forest, gardens, fruit tree.
Other features and advantages of the present invention will partly specify in embodiment subsequently.
