Description
Technical field
The present invention relates to a kind of pesticidal preparations, relate to a kind of pymetrozine suspension agent that contains vegetable oil and derivative thereof specifically.
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.
Pyrrole aphid ketone belongs to pyridines or Triazinone insecticide, is the brand-new non-insects agent of killing livestock, and is developed in 1988 by Switzerland Ciba-Geigy company the earliest, and this product shows excellent control efficiency to the sucking pest of various crop.
Utilize electricity to penetrate figure (EPG) technology research and show no matter be drop, feed or test injection, if aphid or
Plant hopper one touches pyrrole aphid ketone and almost produces the lancet blocking effect immediately, stops to get food at once, and final hungry causing death, and this process is irreversible.Therefore, pyrrole aphid ketone has excellent blocking-up insect and passes malicious function.Pyrrole aphid ketone has action of contace poison to insect, also has systemic activity simultaneously.Can also can be in plant corpus in the phloem transporting in the xylem transporting; Therefore both can be used as foliar spray, also can be used for soil treatment.Because its good transporting characteristic, the branches and leaves that after the cauline leaf spraying, newly grow also can be effectively protected.
Summary of the invention
The objective of the invention is to provides a kind of pymetrozine suspension agent that contains vegetable oil and derivative thereof to the technical problem that background technology proposes; And the preparation method and the application of this suspending agent be provided; 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.
