Embodiment 1

[0011] Weigh 0.01g of 60% Dianron, 0.5g of 96% Bataan, and 5g of 25% Cyanostrobin into a container, add 4000g of water, stir evenly, add 3kg of rice seeds, soak for 24h, and soak at a temperature of 20°C. After soaking the seeds for a sufficient time, the seeds were germinated until the dew white sowing. The seedling raising method was dry seedling. After the seedlings were 20 days old, they were transplanted into the field. After the rice was harvested, 200 grains of rice were randomly selected, crushed and hulled, and the rice grains with black spots were calculated.

Embodiment 2

[0013] Weigh 0.1g of 60% Dianlong, 2g of 96% Bataan, and 15g of 25% Cyanostrobin into a container, add 8000g of water, stir evenly, add 3kg of rice seeds, soak for 48h, soaking temperature is 28 ℃, soak the seeds After enough time, the seedlings were germinated to the dew white sowing. The seedlings were raised by dry seedlings. After the seedlings were 20 days old, they were transplanted into the field. After the rice was harvested, 200 grains of rice were randomly crushed and hulled, and the rice grains with black spots were counted.

Embodiment 3

[0015] Weigh 0.05g of 60% Dianron, 1.25g of 96% Bataan, and 10g of 25% Cyanostrobin into a container, add 6000g of water, stir evenly, add 3kg of rice seeds, soak for 36h, and the soaking temperature is 25°C, After soaking the seeds for a sufficient time, the seeds were germinated until the dew white sowing. The seedling raising method was dry seedling. After the seedlings were 20 days old, they were transplanted into the field. After the rice was harvested, 200 grains of rice were randomly selected, crushed and hulled, and the rice grains with black spots were calculated.

Abstract

The invention discloses a composition. The composition comprises following ingredients: 0.01-0.1g of 60% dazomet, 0.5-2g of 96% cartap, 5-15g of 25% 2-cyano-3-phenyl-3-amino ethyl acrylate, and 4,000-8,000g of water. The invention further discloses an application of the composition to the control of the black eye-spot of rice grains, as well as a method for controlling the black eye-spot of rice grains by soaking seeds. According to the invention, a technical measure of carrying out medicament soaking on rice seeds before the seeds are sowed is used for killing and controlling various pathogenic bacteria in the rice seeds, so that the aim of preventing the black eye-spot of rice grains is realized. The control effect of controlling the black eye-spot of rice grains reaches 100%.

Description

technical field [0001] The invention relates to a method for controlling the formation of black-spotted rice in rice, in particular to a method for controlling the production of black-spotted rice in rice by soaking seeds. Background technique [0002] Black-spotted rice refers to diseases that seriously affect rice quality, such as black spots and cracks on rice grains due to the harm of pathogenic microorganisms or stink bugs during the growth process of rice. The production of black spot rice seriously affects the appearance, quality and quality of rice. According to preliminary investigations, black spot rice occurs in all rice regions of the country, especially in southern rice regions. It is extremely common in early and late rice in Zhejiang Province, with a serious grain incidence rate of more than 90%. For farmers, the rice was rejected by the grain storage department, and it was difficult to sell the grain, which affected the steady growth of farmers' income. SU...
