[0026]Chitooligosaccharide 1g, bifenthrin 10g, clothianidin 29g, polyurethane 10g, ethyl cellulose 10g, sulfonate anionic emulsifier 10g, xanthan gum (thickener) 2g, silicone (defoamer) ) 1g, benzoic acid 0.5g, rose bengal 2.0g, and water to make up the balance. The corresponding quality of the pesticide preparation and the capsule material are mixed and stirred to form an oil phase, stirred for 0.5-1 hour, and heated to 50-80° C. to obtain an oil-phase liquid. Add corresponding quality of water and additives into other reactors, stir until completely dissolved, and heat to 50-80°C to obtain a water phase liquid. Slowly add the oil phase liquid into the water phase liquid. During the adding process, use frequency conversion shearing with a rotation speed of 10,000 to 20,000 rpm. When the oil phase liquid is completely added to the water phase liquid, maintain th...

Abstract

Belonging to the field of agriculture, the invention provides a novel insecticidal composition containing chitosan oligosaccharide. The composition is characterized in that it also contains bifenthrin and thiamethoxam, and the mass percentage content ratio of the chitosan oligosaccharide, bifenthrin and thiamethoxam is 1:2-50:2-50. The composition can be made into suspension concentrates for seed dressing, seed treatment dispersible powder, seed treatment dry powder, water emulsion seed coating agents, microcapsule suspension seed coating agents, suspending agents and the like for control of plant diseases and insect pests and regulation of plant growth.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to an agricultural composition containing oligochitosan, bifenthrin and clothianidin and its application in pest control. Background technique [0002] Plant diseases and insect pests have always been one of the main factors affecting agricultural production, especially soil diseases and insect pests that are difficult to control. The nematodes of the diseased species, some nematodes attack plants from the roots of plants when the conditions are suitable, and cause diseases, and some nematodes hide in the grain chaff as larvae or adults for the winter. After the damage, the ability of the roots to absorb water and fertilizer decreased significantly, the growth of the aboveground parts was slow, the leaves at the base turned yellow after the beginning of flowering, the amount of flowers was greatly reduced, and flowering was delayed. The diseased plants were yellow and wilted in the full f...
