Abstract
The invention discloses a synergist in a water-based pesticide and a preparation method for the synergist, and belongs to the technical field of pesticide synergists. The synergist in the water-based pesticide comprises 30%-65% by weight of a cationic type compound, 1%-10% by weight of a solvent, 1%-15% by weight of inorganic salt, 15%-25% by weight of a wetting agent and 15%-25% by weight of organic silicon. The synergist has the advantages of low residue content, easiness for degradation, good compatibility with a pesticide preparation and the like.
Description
Technical field
The present invention relates to pesticide synergistic agent technical field, particularly relate to synergist in a kind of aqueous pesticide and preparation method thereof.
Background technology
The effect of pesticide synergistic agent, mainly suppresses or weakens target (insect, weeds, germ etc.), to the anti-poisoning effect of the removing toxic substances of pesticide activity, to delay the accretion rate of medicament in controlling object, thus increase biological preventive effect.Synergist itself is non-activity also; but during with corresponding combined use of pesticides; obviously can improve that it is wetting, spread, dispersion, delay and permeance property, reduce spray liquor (air-flow) drift with the wind, prevent or alleviate the infringement to contiguous sensitive crop etc.; be beneficial to liquid blade face sprawl and stick, reduce ultraviolet to pesticidal preparations in the decomposition of active ingredient; reach and extend the drug effect term of validity, improve its biologically active, reduce consumption; reduce costs, the object of preserving the ecological environment.The drug effect quality of pesticidal preparations depends on to a great extent and selects suitable excellent auxiliary agent to realize, and good synergist several times, decades of times can not only improve the control efficiency of agricultural chemicals, also delaying drug resistance can produce, extends the lifetime of hard-won pesticide species.
The synergist of the water baseization pesticidal preparations such as current aqua is mainly: tallow amine ethoxy compound, alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether, APG, silicone based and other compounds.But existing aqua builder product exists that composition is single, aqua synergist DeGrain, quick-acting are poor, aqua builder remains height, difficult degradation, synergist unfriendly on environment and formulation products compatible poor performance, even affect pesticidal preparations physicochemical property, cause the layering of aqua formulation products and occur the problems such as flocculent undissolved substance.
Summary of the invention
In view of this, be necessary for the problems referred to above, the synergist in a kind of aqueous pesticide is provided.The present invention selects the good aqua synergist of composite effect by testing sieve, residual low, easily degrades, good with pesticidal preparations compatibility.
The technical scheme that the present invention takes is:
