Abstract

The invention discloses a composite plant immune resistance inducer and a preparation method thereof. The composite plant immune resistance inducer is prepared from the following raw materials in parts by weight: 10-15 parts of alginate oligosaccharide, 18-22 parts of probenazole, 8-14 parts of lentinan, 8-19 parts of compound amino acid, 5-8 parts of compound sulfate and 1-3 parts of emulsifier.The composite plant immune resistance inducer is prepared by treating and mixing the raw materials, then concentrating by a double-effect falling-film evaporator, and performing spray drying of the concentrated mixed material. Through the synergistic effect of the reasonable components, the composite plant immune resistance inducer provided by the invention not only realizes a perfect effect of preventing and controlling wheat sharp eyespot to increase the wheat yield, but also can improve the wheat quality; meanwhile, after application, the composite plant immune resistance inducer is harmless to both human and livestock, avoids environmental pollution and creates good economic and ecological benefits.

Description

technical field [0001] The invention relates to a compound plant immune inducer and a preparation method thereof, belonging to the technical field of pesticides. technical background [0002] Wheat sheath blight, also known as wheat sharp eye spot disease, has occurred in China since the early 1970s. In recent years, due to climate warming, increased application of chemical fertilizers, especially nitrogen fertilizers, and earlier wheat sowing dates and increased sowing volumes, the occurrence of wheat sheath blight has been increasing year by year, seriously threatening the high and stable yield of wheat. Wheat sheath blight is caused by Rhizoctonia graminearum (4 mycelial fusion groups including CAG-1, CAG-3, CAG-6, and AGC1) and Rhizoctonia solani (AG4 and AG5 fusion groups), and wheat yield loss There is a significant linear correlation with the severity level of sheath blight, and the yield loss increases by about 10% to 20% for each level of severity. The earlier the...
