Problems solved by technology

Among them, the diseases that rice is prone to occur are mainly sheath blight and rice blast, but at present, Jinggangmycin is used to control rice sheath blight, tricyclazole is used to control rice blast, and triadimefon can only control corn sorghum. powdery mildew, etc., but there is no comprehensive control of rice sheath blight, rice blast and other diseases

Embodiment l

[0026] 10% carbendazim, 5% Jinggangmycin A, 5% tricyclazole, 2% sodium alkylnaphthalene sulfonate, 2% pull-off powder, and clay as the balance;

Embodiment 2

[0028] Carbendazim 8%, Jinggangmycin A 6%, Tricyclazole 7%, Sodium Lauryl Sulfate 4%, Naphthalene Sulfonate Formaldehyde Condensate 3%, Diatomaceous Earth as the balance;

[0029] 2. Determination of co-toxicity coefficient

[0030] The toxicity determination method and effect of the composition of carbendazim, Jinggangmycin A and tricyclazole on rice sheath blight are as follows:

[0031] The rice sheath blight fungus is isolated and cultured for 72 hours from the diseased rice plants collected in the field, and a certain amount of medicine is taken and washed with acetone

[0032] The mother liquor of each medicine is prepared according to the active ingredients of the medicine, and then diluted with sterile water to prepare a medicine solution of a corresponding concentration to prepare a culture medium.

[0033] Then the rice sheath blight bacteria were inoculated on the medium containing the medicinal liquid, and another control was set, and cultured in an incubator for ...

Embodiment 3

[0038] The preparation of Example 1 was tested with carbendazim wP and Jinggangmycin for the control of rice sheath blight.

[0039] Experimental crop: rice Application period: Rice booting stage, the early stage of sheath blight onset, the pesticide application is started, and the pesticide is applied again 9 days after the pesticide application, and the pesticide is applied twice in total.

[0040] Record:

[0041] The disease base was investigated before the application of the drug, and the development of the disease was investigated 9 days after the first application of the drug, that is, before the second application of the drug and 10 days after the second application of the drug. The survey of plots adopts sampling at 5 diagonal points, and 5 clusters of rice are taken at each point. A total of 25 clusters of rice are surveyed in each plot. Control effect.

[0042] Drug efficacy calculation method:

[0043] Disease index = ∑ [number of diseased plants (leaves) at all...

Abstract

The invention relates to a bactericide composition for preventing and treating rice diseases. The bactericide composition comprises the following components: carbendazim, validamycin A and tricyclazole with the weight ratio of 5-20% of the carbendazim, 2-10% of the validamycin A, and 2-10% of the tricyclazole. The bactericide composition provided by the invention can comprehensively prevent and treat main rice diseases of banded sclerotial blight and rice blast, with the prevention and treatment effect on the rice banded sclerotial blight reaching 86.11-87.95%, and the prevention and treatment effect on the rice blast reaching 98.95%, has certain extended effects of inhibiting the rice banded sclerotial blight and the rice blast, and can promote the production of rice and improve the yield by averagely 7.5%.

Description

technical field [0001] The present invention relates to a fungicide composition, in particular to a bactericide containing Jinggangmycin A for preventing and treating rice diseases. [0002] Fungicide composition. Background technique [0003] my country is a big agricultural country. Rice is an important food crop in China. Its production has a long history and [0004] Important position. Rice has been planted in China for more than 5,000 years, with high and stable rice yields, accounting for 10% of the country's total grain output. [0005] l / 2; rice is widely distributed, accounting for l / 4 of the country's arable land. However, rice is harmed by various pathogens in the production process, which restricts the yield and quality of rice, and in severe cases, the yield can be reduced by 40-50%. Among them, the diseases that rice is prone to occur are mainly sheath blight and rice blast, but at present, Jinggangmycin is used to control rice sheath blight, tricyclazole ...
