Description
Technical field
The present invention relates to a kind of pesticidal preparations, a kind of specifically Imidacloprid suspension formulation that contains vegetable oil and derivative thereof.
Background technology
Agricultural chemicals suspension agent is many to be dispersion medium with water, and the insoluble or former medicine of solid that is slightly soluble in water by the effect of surfactant and other auxiliary agent, evenly disperses the more stable liquid-solid phase system that form the tiny higher suspension of a kind of particle, can flow through grinding.Compare with missible oil, the advantage that avoids the use of a large amount of organic solvents is arranged; Compare with wettable powder, do not have the dust drift of dispersing in processing with when using, all lower to people and animals' toxicity and excitant, can alleviate poisoning to crop, more can in preserving transportation, not burn, safety is higher; The danger that user and entire environment are caused is quite low.Yet suspending agent is meant solid granule and is suspended in the water, dimension in use, soup spray cloth is on the plant leaf blade surface; Behind liquid evaporation; Medicament covers blade surface with the form of solid granule, when external environment changes, is easy to cause the loss of agricultural chemicals solid particle like strong wind, rainwater weather; Therefore the medicament availability is lower in use for this kind formulation, and field efficacy is also not ideal enough.
Imidacloprid is a nicotinic insecticide, has wide spectrum, efficient, low toxicity, low-residual, and insect is difficult for producing resistance, to characteristics such as people, animal, plant and natural enemies securities, and have tag, stomach toxicity and the multiple drug effect of interior suction.Behind the insect contact medicament, the nervous centralis normal conduction is obstructed, and makes its paralysis dead.Quick-acting is good, higher preventive effect is promptly arranged in 1 day behind the medicine, and residual life reached about 25 days.Drug effect and temperature are proportionate, and temperature is high, good disinsection effect.
Be mainly used in the control sucking pest, like aphid, plant hopper, aleyrodid, leafhopper, thrips; To coleoptera, diptera and lepidopterous some insect, also effective like Lissorhoptrus oryzophilus Kuschel, rice leaf beetles, rice borer, leaf miner etc.But it is invalid to nematode and two spotted spider mite.Can be used for crops such as paddy rice, wheat, corn, cotton, potato, vegetables, beet, fruit tree.
Summary of the invention
The objective of the invention is to provides a kind of Imidacloprid suspension formulation that contains vegetable oil and derivative thereof, and the preparation method and the application of this suspension formulation is provided to the technical problem that background technology proposed.It has solved the problem that the missible oil of wetting powder and low content works the mischief to people, livestock and environment, has solved the suspending agent drug effect again technically and has showed dissatisfactory problem.
The present invention has added vegetable oil and derivative thereof as oil phase component in suspending agent, have anti-evaporating, medicament is sprawled advantages such as adhesive ability is strong, permeability is strong, has therefore improved the biologically active of original formulation products, significantly improves preparation field result of use.
