Technical Field

The invention relates to the field of pesticides, and particularly relates to a combined bactericide for preventing and treating false smut.

Background

The false smut is also called green smut, which usually occurs on middle and late rice, but more commonly occurs on hybrid rice and high-quality rice, and the disease mainly damages the ear and can reduce the yield by 10-20%. Along with the increase of japonica rice planting and nitrogen fertilizer application level, false smut gradually rises from secondary diseases to main diseases. False smut not only affects yield, but also its pathogen is a substance containing poison to human, livestock and poultry and pathogenic pigment C9H 607. For such diseases, the application of chemical agents is currently the most effective means. The commonly used medicaments are conventional medicaments such as thiophanate methyl, validamycin, triazolone, carbendazim and the like, and because the medicaments are popularized in a large area from the last 70 th century, chemical bactericides with single varieties or action modes are continuously used for a long time at high dosage, and the problems of medicament residue, environmental pollution, drug-resistant fungus development and the like are easily influenced. According to the research in 2003 of agricultural institute of Zhenjiang, Jiangsu, the resistance of Ustilaginoidea virens to carbendazim in Yangtze river is increased by 2-3 times on average compared with that in 1995, and the adverse factors such as increased application amount, increased application times, reduced control effect and the like are brought as the result.

Disclosure of Invention

The invention aims to provide a composite bactericide for preventing and treating false smut, which has better bactericidal effect and obvious prevention and treatment effect.

The invention aims to realize that the combined bactericide for preventing and treating false smut comprises 15 ~ 30% of coumoxystrobin, 10 ~ 25% of prochloraz, 5-12% of tricyclazole, 5 ~ 35% of an auxiliary agent and the balance of filler according to weight percentage.

As a further improvement of the invention, the auxiliary agent comprises 2-10% of wetting agent, 1-10% of dispersing agent, 1-5% of binding agent and 1-5% of disintegrating agent, and the filling material at least comprises one of clay, kaolin or bentonite, so as to obtain the water dispersible granule of the composite bactericide for preventing and treating false smut of rice.

As a further improvement of the invention, the wetting agent is saposhn, the dispersing agent is sodium dodecyl sulfate, the binder is gum arabic, and the disintegrating agent is ammonium sulfate.

As a further improvement of the invention, the auxiliary agent comprises 1-8% of emulsifier, 1-5% of antifreeze, 0.1-2% of thickener and 3-15% of solvent, and the filler is water, so as to obtain the suspending agent of the combined bactericide for preventing and treating false smut of rice.

As a further improvement of the invention, the emulsifier is calcium alkyl benzene sulfonate, the antifreezing agent is ethylene glycol, the thickener is hydrogenated rosin glyceride, and the solvent is toluene.
