Description
The application is that the application number that proposed on June 1st, 2012 is 201210180211.9, name is called dividing an application of " a kind of fosthiazate insecticides and application thereof ".
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 by root, stem, leaf or other position of plant, is absorbed to enter in plant corpus, and conducts in plant corpus.Contact or take food medicament and be 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 that endangers this position, and medicament does not hinder growing of plant.
Have interior suction, conduction in the plant body due to systemic insecticide, therefore, this insecticides has the characteristics different from other insecticides, as desinsection wide spectrum more, selectivity is stronger, can effectively kill and hide or borer pest, be not subjected to the impact of rainfall, save time, saving of labor, province's medicine etc.In several low toxic pesticide kinds of applying in recent years, brought into play great function in the agricultural industry.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 poor defective of existing systemic insecticide control efficiency.
The present inventor is unexpected the discovery under study for action, by with the fosthiazate of the certain content active component as insecticides, can greatly improve the control efficiency of the insecticides that obtains, 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, described composition contains active component and solvent, it is characterized in that, described active component contains the fosthiazate as main active, and described fosthiazate accounts for the 20-100 % by weight of active component total amount, be preferably the 30-90 % by weight, more preferably the 50-60 % by weight.
Preferably, described active component also contains at least a systemic insecticide except fosthiazate.
The weight ratio of fosthiazate and described at least a systemic insecticide except fosthiazate is preferably 1:0.12-2.3, more preferably 1:0.67-1.
Preferably, described at least a systemic insecticide except fosthiazate is at least a in carbosulfan, Imidacloprid, Acetamiprid, Diacloden, Nitenpyram, clothianidin, MTI-446, imidaclothiz, Rynaxypyr, Aphox, chlorophos, isazofos, pirimiphos-methyl, omethoate, orthene, thiacloprid, butyl pyrimidine phosphorus, ethiprole, capillary and pymetrozine; At least a in Imidacloprid, Acetamiprid, Diacloden, Rynaxypyr and thiacloprid more preferably.
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 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 use procedure; 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; Reduce the consumption of every kind of systemic insecticide, reduced the impact on environment, safer to people and animals.Fosthiazate insecticides provided by the invention can be widely used in the agriculture and forestry desinsection such as forest, gardens, fruit tree field.
Other features and advantages of the present invention will partly be described in detail in embodiment subsequently.
