Embodiment 2

[0054] Embodiment 2 of the present invention: the pesticide for preventing and treating rice blast includes tricyclazole and rice blastling, and the mass ratio of tricyclazole and rice blastling is 1:3.

Embodiment 3

[0055] Embodiment 3 of the present invention: Pesticides for preventing and treating rice blast include tricyclazole and rice blastling, and the mass ratio of tricyclazole and rice blastling is 4:1.

[0056] Embodiment 4 of the present invention: Pesticides for preventing and treating rice blast include tricyclazole and rice blastling, and the mass ratio of tricyclazole and rice blastling is 3:1.

[0057] Embodiment 5 of the present invention: Pesticides for preventing and treating rice blast include tricyclazole and rice blastling, and the mass ratio of tricyclazole and rice blastling is 2:1.

[0058] In the above-mentioned examples, tricyclazole was selected as 75% tricyclazole wettable powder (Hebei Guanlong Agrochemical Co., Ltd.); Daobunling was selected as 40% Daobunling emulsifiable concentrate (Chongqing Dongfang Pesticide Co., Ltd.) . Their mass ratio refers to the mass ratio of the active ingredients of the product.

Abstract

The invention discloses an agricultural chemical for preventing and controlling rice blast. The agricultural chemical comprises tricyclazole and isoprothiolane, wherein the mass ratio of the active ingredients of tricyclazole and isoprothiolane is (1-4): (1-3). The tricyclazole and isoprothiolane are compounded and mixed, so that the tricyclazole and the isoprothiolane have synergized action, the problem that agricultural chemical resistant rice blast germs have agricultural chemical resistance to single tricyclazole or isoprothiolane is overcome, the using amount of the agricultural chemical can be efficiently reduced, the labor intensity is reduced, the cost is saved, and the problem of abusing agricultural chemicals is solved. The agricultural chemical for preventing and controlling the rice blast is simple, wide in material source, low in cost and good in result of use.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a pesticide for preventing and treating rice blast. Background technique [0002] In recent years, my country's rice planting area has been relatively stable at more than 400 million, accounting for about 30% of the grain crop area, and the output is close to half of the total grain output. Rice blast is one of the three major diseases of rice in my country. This disease occurs in all rice producing areas in my country and can cause a large reduction in yield. Especially the early and severe panicle blast can cause white ears and even extinction. At present, in production practice, a single pesticide is generally used for the control of rice blast. Single-drug control of rice blast, the bacteria are more likely to develop resistance, which will inevitably lead to a multiplied increase in the number of control times and the amount of pesticides used in productio...
