Description
Technical field
The present invention relates to a kind of pesticidal preparations, be specifically related to a kind of imidacloprid suspending agent.
Background technology
Imidacloprid is a kind of nitro-methylene-type systemic insecticide, it is the acting body of nicotinic acid nAChR ligands, disturb the pest movements nervous system that chemical signal is transmitted malfunctioning, without the cross resistance problem, for preventing and treating sucking pest such as aphid, aleyrodid etc., it usually adds the auxiliary agents such as surfactant in use, but the improper meeting that adds of auxiliary agent affects, and even reduces the drug effect of Imidacloprid.
Water baseization is the main direction of formulations of pesticide exploitation, and suspending agent is one of wherein important formulation, and suspending agent is a kind of thermodynamic unstable system, along with passage of time, finally unavoidably the variation of state can occur, and the quality problems such as layering, the knot end occur.In order when using the suspending agent preparation, to obtain satisfied performance and biological agent, need to make reactive compound and the better combination of auxiliary agent in suspending agent.Herein, auxiliary agent is a kind of composition that improves the reactive compound biological agent, but this composition itself does not have biological agent.Particularly, auxiliary agent can promote that reactive compound is absorbed.The size of suspending agent particle diameter directly has influence on the quality of product, and particle diameter is large the quality problems such as layering, the knot end, suspensibility be low easily occur, thereby affects the performance of drug effect.At present general suspending agent 90% particle diameter is 5 microns left and right, even larger.And the main factor that affects particle diameter is the selection of the auxiliary agents such as surfactant, if auxiliary agent does not choose, be difficult to guarantee particle diameter, and drug effect is not stable in performance.
The objective of the invention is for the deficiencies in the prior art, mainly by the selection of auxiliary agent, provide that a kind of suspensibility is higher, the suspension agent composition that contains Imidacloprid that heat storage performance is more stable, drug effect is better.
