Abstract

The invention discloses a moisture-holding sustained-release seed treating agent for controlling wheat sharp eyespot. The treating agent comprises components in parts by weight as follows: 2.5-3.3 parts of difenoconazole, 9-12 parts of a moisture-holding agent, 10-13 parts of wetting dispersants, 4-6 parts of a film-forming agent, 1-2 parts of dye, 3-5 parts of a sinking agent and 63.7-65.5 parts of a carrier, wherein the difenoconazole is a 95% raw drug, the moisture-holding agent is in the polyacrylamide type, the wetting dispersants are an emulsifier OP-10 and an NNO (naphthalenesulfonic acid/formaldehyde condensation product), the film-forming agent is polyvinyl alcohol 1788, the dye is carmine, the sinking agent is a mixture of argil and xanthan gum in the mass ratio of 3:1, and the carrier is white carbon black. The moisture-holding sustained-release seed coating has the characteristics of good film-forming property, evenness in coating, low toxicity and environment friendliness and can increase the emergence rate of wheat significantly, prolong the lasting period of the agent and increase the utilization rate of soil moisture and the yield of the wheat.

Description

technical field [0001] The invention relates to a water-retaining and slow-release seed treatment agent for preventing and treating wheat sheath blight, belonging to the technical field of agriculture. Background technique [0002] Wheat sheath blight, also known as wheat sharp eye, is mainly caused by Rhizoctonia graminearum ( Rhizoctonia cerealis ) is a soil-borne fungal disease that occurs in all major wheat-producing regions of the world. Since the 1970s, with the replacement of wheat varieties and the promotion of high-yield cultivation measures (such as early sowing, close planting, high fertilizer, etc.), the disease has commonly occurred in winter wheat areas in my country, and has become a common disease in the Huanghuaihai Plain and the Yangtze River Basin. one of the major diseases of the region. At the same time, due to the increase of mechanical cross-regional operations in my country in recent years, wheat sheath blight has gradually spread northward, and the ...
