Abstract
The invention discloses a pesticide composition with active ingredients of trifloxystrobin and propamidine. The pesticide composition comprises a common assistant, trifloxystrobin and propamidine, wherein the weight part ratio of trifloxystrobin to propamidine is (9:1) to (1:7), and the total weight of trifloxystrobin and propamidine accounts for 3-90 percent of the weight of the insecticide composition. Trifloxystrobin and propamidine have a remarkable synergistic effect after being compounded, the consumption of the active ingredients of the compound pesticide is remarkably reduced in comparison with that of trifloxystrobin or propamidine, the pesticide composition is suitable for controlling crop diseases caused by pathogen fungi, especially crop gray mold caused by botrytis pathogens and crop anthracnose and damping-off caused by colletotrichum pathogens.
Description
Technical field
The composition pesticide that the present invention relates to, specifically a kind of composition pesticide containing oxime bacterium ester and propamidine.
Background technology
Oxime bacterium ester, english common name Trifloxystrobin, for methoxy acrylic series bactericidal agent, oxime bacterium ester is to 1, 4-demethylation enzyme inhibitor, benzamides, the bacterial strain that dicarboxyl amine and benzimidazole produce resistance is effective, with current existing bactericide without cross resistance, to nearly all Mycophytes (Ascomycetes, Basidiomycetes, Oomycete and Fungi Imperfecti) disease is as powdery mildew, rust, Ying's rot, net blotch, downy mildew, rice blast etc. all have good activity, remove powdery mildew, leaf spot has outside special efficacy, to rust, downy mildew, damping off, apple apple scab, sclerotinia rot of colza has good activity, to crop safety.
Propamidine, english common name Propamidine, belongs to aromatic diamidino compounds; propamidine is systemic fungicide; in plant body absorption, distribution and metabolism, protection and therapeutic action can be had, be mainly used in preventing and treating the crop gray mold caused by Botrytis pathogen.
The mixture of different pesticide species is the common methods of preventing and treating agriculture resistance disease.Screened by formulation of pesticide, filter out rational formula, can effectively improve actual control efficiency, reduce dosage, reducing costs, delay the generation of disease drug resistance, is the important means of the disease comprehensive regulation.
Oxime bacterium ester and the composite protective effect enhanced crop of propamidine, reduce the resistance risk being used alone oxime bacterium ester or propamidine and bringing simultaneously, has no oxime bacterium ester and the composite report of propamidine at present.
Summary of the invention
The technical problem that the present invention need solve be to provide a kind of efficient, low toxicity, quick-acting are good and the lasting period is long, are conducive to the composition pesticide containing oxime bacterium ester and propamidine of the disease comprehensive regulation.
For solving the problem, the technical solution adopted in the present invention is: a kind of composition pesticide containing oxime bacterium ester and propamidine, comprise usual auxiliaries and oxime bacterium ester and propamidine, oxime bacterium ester and propamidine ratio of weight and number are 9:1 ~ 1:7, and oxime bacterium ester and the percentage by weight of propamidine weight summation in composition pesticide are 3% ~ 90%.
Further: the above-mentioned composition pesticide containing oxime bacterium ester and propamidine can according to well known to a person skilled in the art method, adopt suitable insecticides adjuvant, be configured to suspending agent, dispersible oil-suspending agent, water dispersible granules, wetting powder etc. are applicable to the formulation that agriculturally uses.
The insecticides adjuvant used in composition pesticide of the present invention comprises solvent, emulsifier, wetting agent, disintegrant, stabilizing agent, dispersant, thickener, penetrating agent, pH adjusting agent, defoamer, antifreezing agent, carrier etc., and to be of value to active ingredient stable and play the known substance of drug effect in the formulation, be all various compositions that are conventional in pesticidal preparations or permission use, concrete composition and consumption are determined by test according to recipe requirements.
The frequency of administration of composition pesticide of the present invention and amount of application change with crops, insect, weather condition and have small variations, can by the object using suitable dosage reach effectively control.
Composition pesticide of the present invention is applicable to control by the fungus-caused crop pest of pathogen, anthracnose, damping off that crop gray mold, colletotrichum (Colletotrichum) pathogen that especially Botrytis (Botritis) pathogen causes cause.
Compared with prior art, the invention has the advantages that:
1, the control efficiency of composition pesticide of the present invention is significantly improved than single dose, reduces the using dosage of agricultural chemicals, reduces cost.
2, the active ingredient mechanism of action of composition pesticide of the present invention is different, and the application of composition can delay or overcome the drug-fast generation of germ, is conducive to the comprehensive regulation.
