Abstract
The present invention discloses one kind of germicide composition containing Kresoxim-methyl and tricyclazole and its application. The composition contains Kresoxim-methyl and tricyclazole in the weight ratio of 1-40 to 1-40. 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
Technical field
The present invention relates to a kind of bactericidal composition and uses thereof, especially a kind of is the bactericidal composition and the application thereof of main active with kresoxim-methyl and tricyclazole.
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 powdery mildew of strawberry, melon powdery mildew, powdery mildew of cucumber, pear scab special efficacy.
But the former medicine production of kresoxim-methyl is less in China, and its price is high, is difficult to prevent and treat in the farmland promote the use of aspect the disease.
Tricyclazole (tricyclazole) is a kind of efficient, interior absorption azoles fungicide, and control rice blast is had special efficacy, can suppress spore germination, by suppressing Pyricularia oryzae the infection point that forms in plant surface infection and the plant is stoped the rice blast circulation.But, because preventing and treating disease for a long time in the farmland, uses tricyclazole, reduce greatly in its drug effect aspect the control rice blast, can not be used to prevent and treat diseases such as rice blast with positive usual amounts.
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 tricyclazole.
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 tricyclazole, and wherein the weight ratio of kresoxim-methyl and tricyclazole is 1～40: 1～40.
Described bactericidal composition, wherein the weight ratio of kresoxim-methyl and tricyclazole is 3～30: 5～30.
Described bactericidal composition, wherein kresoxim-methyl and tricyclazole 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, missible oil or granule.
The application of described bactericidal composition aspect control cereal class, melon and fruit or vegetable crop damage by disease and insect.
Beneficial effect of the present invention:
1, the used kresoxim-methyl of the present invention is an acid amide fungicides, and tricyclazole 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.
