Embodiment 1

[0026] Example 1: 20% cyclostrobin · cloconazole wettable powder

[0027] Cyclostrobin 4%, Paconazole 16%, NNO-1 1%, Pull open powder 3%, Sodium dodecylbenzene sulfonate 2%, Attapulgite 30%, The rest is supplemented by light calcium carbonate to 100%. The above components were thoroughly mixed, pulverized by a sand mill and sieved through a 300-mesh sieve to obtain a 20% cyclostrobin-conconazole wettable powder.

Embodiment 2

[0028] Example 2: 60% cyclostrobin · cloconazole wettable powder

[0029] Cyclostrobin 40%, Paconazole 20%, NNO-1 1%, Pull open powder 3%, Sodium dodecylbenzene sulfonate 2%, Attapulgite 30%, The rest is supplemented by light calcium carbonate to 100%. The above components were thoroughly mixed, pulverized by a sand mill and sieved through a 300-mesh sieve to obtain a 60% cyclostrobin-conconazole wettable powder.

Embodiment 3

[0030] Example 3: 40% cyclostrobin·canconazole wettable powder

[0031] Cyclostrobin 20%, Paconazole 20%, NNO-1 1%, Pull open powder 3%, Sodium dodecylbenzene sulfonate 2%, Attapulgite 30%, The rest is supplemented by light calcium carbonate to 100%. The above components were thoroughly mixed, pulverized by a sand mill and passed through a 300-mesh sieve to obtain a 40% cyclostrobin-conconazole wettable powder.

Abstract

The invention provides an application of a pesticide composition containing JS399-19 and ipconazole to prevention and treatment of rice bakanae disease and discloses a novel application of the pesticide composition to the prevention and treatment of the rice bakanae disease. The pesticide composition is prepared from the raw materials in parts by weight: 1-60 parts of JS399-19 and 1-40 parts of ipconazole. The pesticide composition provided by the invention has a remarkable synergistic effect on inhibition of the growth of germ hyphae of the rice bakanae disease, and also has a good effect on field prevention and treatment of the rice bakanae disease; and the use amount of the pesticide can be remarkably reduced, the cost is reduced, the environmental pollution is reduced and pesticide residues are reduced. The pesticide composition can be used for effectively managing the drug resistance of the rice bakanae disease on mainstream pesticides including carbendazim and prochloraz, and the drug resistance risk of the JS399-19 in agricultural production is reduced so that the effective service life is prolonged; and the pesticide composition can be used for treating seedling diseases of seedlings, caused by soil-borne fusarium and rhizoctonia, and has an application value on resistance management of the rice bakanae disease of China, and increasing social, economic and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to the use of a pesticide composition in preventing and treating bakanae disease of rice, and also relates to the use of an agricultural fungicide in preventing and treating bakanae disease of rice. Background technique [0002] Cyclostrobin (test number: JS399-19, English name: phenamacril), chemical name: ethyl 2-cyano-3-amino-3-phenylacrylate, molecular formula: C 12 h 12 N 2 o 2 , the chemical structural formula is as follows: [0003] [0004] Cyanostystrobin is a new type of cyanoacrylate selective fungicide developed by the Jiangsu Base of the National Southern Pesticide Innovation Center. Specialized inhibition. The new fungicide has obtained the Chinese invention patent, and completed the provisional pesticide registration in 2005 and the official registration in 2011. Since cyanoxystrobin entered the market, it has played an important role in the pr...
