On the basis of above-mentioned discovery, after further study, define technical scheme of the present invention, that is: a kind of bactericidal composition containing pyrrole metsulfovax and fludioxonil, active ingredient is pyrrole metsulfovax and fludioxonil, pyrrole metsulfovax and fludioxonil ratio of weight and number is in the composition 1:10 ~ 10:1, and pyrrole metsulfovax and fludioxonil weight summation in the composition percentage by weight are 1% ~ 90%, and all the other are the pesticidal preparations auxiliary element that agriculturally can accept and allow to use.
Bactericidal composition of the present invention according to well known to a person skilled in the art method, can be processed into the application forms of the applicable agricultural uses such as aqueous emulsion, microemulsion, suspending agent, wetting powder, water dispersible granules.
Bactericidal composition of the present invention is also containing the auxiliary element of preparation needed for pesticidal preparations, comprise one or more mixing in emulsifier, wetting agent, stabilizing agent, dispersant, thickener, defoamer, antifreezing agent, disintegrant, binding agent, filler, filler, medium etc., be known substance, various auxiliary agents conventional in pesticidal preparations, can change to some extent according to different situations, be not particularly limited
Bactericidal composition of the present invention, for preventing and treating melon and graw mold of tomato, during dispenser should disease occur before or initial stage of origination use.
Bactericidal composition provided by the invention, usually adopts spray method to use, also can adopt other operation techniques agriculturally applied as required.
A kind of bactericidal composition containing pyrrole metsulfovax and fludioxonil provided by the invention has following beneficial effect:
1, bactericidal composition provided by the invention, obvious synergy or summation action is shown in certain ratio range, the control efficiency of composition to germ is significantly improved than single dose, reduce the using dosage of agricultural chemicals, decrease times for spraying, reduce drug cost, decrease the adverse effect of agricultural chemicals to ecotope.
2, bactericidal composition provided by the invention, the combination of two kinds of active ingredients, expands fungicidal spectrum, and a drug can solve multiple diseases problem, compensate for defect when single dose uses and limitation.
3, bactericidal composition provided by the invention, two kinds of active ingredient mechanism of action are not quite identical, can overcome the shortcoming that long-term single use easily produces resistance, extend the service life of medicament, to the comprehensive regulation important in inhibiting of germ resistance.
4, bactericidal composition provided by the invention, drug effect plays rapidly, and the lasting period is long, and use cost is low, easy to use, time saving and energy saving, and it applies huge economic benefit and social benefit.
