Abstract
The invention discloses a bactericide with tricyclazole and fluorine organism bacteria ester. The bactericide is characterized in that the weight ratio of tricyclazole to the fluorine organism bacteria ester is 1:50-20:1. The bactericide further comprises an auxiliary and a carrier. The weight of the tricyclazole and the fluorine organism bacteria ester accounts for 5-60% of the total weight of the bactericide, the weight of the auxiliary accounts for 5-30% of the total weight of the bactericide, and the balance is the carrier. Actual tests prove that the bactericide has the remarkable control effect on rice blast.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericide preventing and treating rice blast.
Background technology
Rice blast is the Major Diseases of paddy rice, and seedling morbidity is often crispaturaed withered; Also can be withered or have a strong impact on and grow when tillering stage, leaf spot lesion was many; The morbidity of rice strain stipes subjects to windbreak; Fringe neck and the morbidity of branch stalk then cause dead ears or half dead ears, lose very large.The measure of current control rice blast depends on spraying fungicide, but Pyricularia oryzae develops immunity to drugs for the most of bactericide preventing and treating rice blast in production, is wherein no lack of the medicament that Isoprothiolane, tricyclazole etc. are efficient, the lasting period is long.Therefore, the screening of pesticide new variety, novel form and the development of new complex preparation or introducing are the important measures reducing fungicide resistance risk, the service life extending them and resistance management.Select the biopesticide of high-efficiency low-toxicity simultaneously, the rational mixture of different agricultural chemicals uses and develop new high-efficiency preparation control rice blast with and have great economic benefit, social benefit and Ecological Effect
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of bactericide containing tricyclazole and fluorine nalidixic bacterium ester with the control rice blast of better control efficiency.
Of the present invention containing tricyclazole and the composite bactericide of fluorine nalidixic bacterium ester, its active ingredient is tricyclazole and fluorine nalidixic bacterium ester, and wherein the weight ratio of tricyclazole and fluorine nalidixic bacterium ester is 1:50-50:1; Also include auxiliary agent and carrier in said composition, wherein tricyclazole and fluorine nalidixic bacterium ester account for the 5%-60% of bactericide gross weight, and auxiliary agent accounts for the 5%-30% of bactericide gross weight, and all the other are carrier, and wherein said auxiliary agent is.
Of the present invention can be water dispersible granules, wetting powder or aqueous emulsion containing tricyclazole and the composite bactericide of fluorine nalidixic bacterium ester.
Bactericide of the present invention, through actual test, has significant control efficiency to rice blast.
Compound disinfectant of the present invention, compared with conventional sterilization agent, has the following advantages: 1, this kind has obvious synergistic effect to rice blast compared with single dose, can significantly improve control efficiency; 2, reduce dosage, reduce the residual of environmental pollution and agricultural product; 3, can delay the pesticide resistance of rice blast to single bactericide, 4, have prophylactic treatment effect, the lasting period is long, compared with single medicament, can reduce costs.
