Description
Technical field
The present invention relates to pesticide field more particularly to a kind of suspending agents of the composite bactericide of jinggangmycin A and metconazole
And preparation method thereof.
Background technology
Rice sheath blight disease (Rice Sheath Blight) is one of the rice disease that distribution is wide in the world, harm is big, mesh
Before have gone up as first of three major disease of China's rice.After rice is infected by sheath blight fungus, setting percentage and mass of 1000 kernel significantly reduce, very
It can extremely cause rice strain lodging or complete stool withered, the general underproduction 5%~10% is serious up to 50%~70%.
Prevention to rice sheath blight disease relies primarily on jinggangmeisu in production and is prevented for many years, jinggangmeisu
(validamycin) it is farm antibiotics that early 1970s Shanghai pesticide research is filtered out, becomes for streptomyces hygroscopicus
Kind (S.hygroscopicus.var), including six components of A, B, C, D, E, F, jinggangmycin A is main component.But with disease
The accumulation of bacterium drug resistance, in recent years control effect be decreased obviously.
Metconazole (thifluzamide) is a kind of novel thiazole acid amide fungicides, and there is strong uptake and translocation and length to hold
Effect property.Main function is the acidohydrogenase inhibited in disease fungus tricarboxylic acid cycle, causes thalline dead.Metconazole is succinic acid
Ester dehydrogenase inhibitor, due to fluorine-containing, its competitiveness is very strong in biochemical process, is not easy once being combined with substrate or enzyme extensive
It is multiple.Metconazole is to pathomycetes such as Rhizoctonia, Puccinia, Ustilago, Tilletia, corticium, Pyrenophoras
It is active, especially there is special efficacy to Basidiomycetes fungus-caused disease such as banded sclerotial blight, damping-off etc..Metconazole is to algal fungi class
It is not active, it is bad to the disease effect caused by leaf portion pathogen.It is applied alone the metconazole single dose of high-content to be used at present simultaneously
Cost is higher.
Sharing synergy for jinggangmycin A and metconazole at present has certain research and application, still, for body with high salt
It is still not yet to be solved in industry that the particle size growth of metconazole how is resisted under the stabilization technique and high salt that are low suspension agent
Problem.
Specifically, since one of active ingredient jinggangmycin A is water-soluble active compound, sugar content is higher, is processed into suspension
Agent, which exists, is sanded viscosity increase, can not be sanded, and storage sets in the process and occurs gluing wall, the generation of generation black floccule, and
Surfactant-dispersed ability, which is damaged, under high salt causes to compound kind particle size growth with it apparent, and it is existing knot bottom occur
As seriously affecting the appearance and quality of product.
Invention content
The purpose of the present invention is to provide a kind of stability that can ensure high salt low suspension agent and effectively resistances
The jinggangmycin A of the particle size growth of metconazole and the suspending agent of composite bactericide of metconazole and preparation method thereof.
To achieve the above object, the present invention provides a kind of suspending agent of the composite bactericide of jinggangmycin A and metconazole, packet
