Abstract

The present invention discloses one kind of germicide composition containing Kresoxim-ethyl and isoprothiolane and its application. The composition contains Kresoxim-ethyl and isoprothiolane in the weight ratio of 5-40 to 5-50. The composition may be used in preventing and controlling diseases of grain crop, melons, fruits and vegetable, and has wide application range, low cost and high plant disease preventing and controlling effect.

Description

A kind of bactericidal composition and application thereof that contains kresoxim-methyl and Isoprothiolane
Technical field
The present invention relates to a kind of bactericidal composition and uses thereof, especially a kind of with kresoxim-methyl and Isoprothiolane, be the bactericidal composition and the application thereof of main active.
Background technology
Kresoxim-methyl (kresoxim-methyl) is a kind of efficient, wide spectrum, new type bactericide.Diseases such as powdery mildew of strawberry, melon powdery mildew, powdery mildew of cucumber, pear scab had good preventive effect.Kresoxim-methyl not only has the bactericidal activity of wide spectrum, simultaneously with excellent protection and therapeutic action.There is not cross resistance with other bactericide commonly used, and longer than the conventional sterilization agent lasting period.Have the selectivity of height, to crop, people and animals and beneficial organism safety, pollution-free substantially to environment.Kresoxim-methyl has good active to fungus-caused multiple diseases such as imperfect fungus, sac fungi, basidiomycetes, Oomycetes, as: diseases such as grape powdery mildew, wheat rust, potato late blight, pumpkin eqpidemic disease, rice blast, especially to the powdery mildew special efficacy.Because its drug cost height uses not extensive.
Isoprothiolane (isoprothiolane) is a kind of systemic fungicide.Rice blast is had special efficacy, and rice plant can suppress the germ intrusion after absorbing, and has especially suppressed phosphide N-methyltransferase, thereby suppresses the germ growth, plays prevention and therapeutic action.Isoprothiolane for a long time, repeatedly uses on rice in China producing region and other crops, and this germ that makes strengthens gradually to its resistance, and the cost that makes Isoprothiolane prevent and treat disease increases.
Summary of the invention
The objective of the invention is at above-mentioned technical problem provide a kind of applied widely, cost is low, the effective plant sterilization composition that contains kresoxim-methyl and Isoprothiolane.
A further object of the invention provides the purposes of this bactericidal composition.
The objective of the invention is to realize by following measures:
A kind of bactericidal composition, it contains kresoxim-methyl and Isoprothiolane, and wherein the clever weight ratio of kresoxim-methyl and rice blast is 5~40: 5~50.
Described bactericidal composition, wherein kresoxim-methyl and Isoprothiolane weight ratio are 5~30: 10~50.
Described bactericidal composition, wherein kresoxim-methyl and Isoprothiolane and known auxiliary agent and excipient are re-dubbed any one formulation that allows on the agricultural chemicals.These known auxiliary agents, excipients have dispersant, diffusant, defoamer, wetting agent, disintegrant etc.
Described bactericidal composition, its formulation are pulvis, wetting powder, suspension emulsion or granule.
The application of described bactericidal composition aspect control cereal class, melon and fruit or vegetable crop disease.
Beneficial effect of the present invention:
1, the used kresoxim-methyl of the present invention is an acid amide fungicides, and Isoprothiolane is an azoles fungicide, be mixed mutually to produce low touching, but Synergistic reduces dosage, reduces cost.
2, the present composition scope of application increases, be applicable to the crop pest of control cereal class, various melon and fruit, vegetables, particularly prevent and treat crop pests such as paddy rice, wheat, capsicum, banana, mango, pineapple, cucumber, tomato, as wheat powdery mildew, pepper anthracnose, balsam pear scab, scutellum rot of orange, powdery mildew of cucumber, early blight of tomato and late blight.
