Problems solved by technology

[0005] Clothianidin seed treatment and root zone application technology have been widely used, and this type of application technology has the advantages of prolonging the duration of action, reducing the risk of natural enemies and occupational exposure risk, but limited by the conduction rate, the aboveground Pest control effectiveness will be delayed, resulting in reduced availability of clothianidin and possible oxidative stress in the plant

Abstract

The invention discloses a clothianidin-containing seed treatment suspending agent and a preparation method thereof, the clothianidin-containing seed treatment suspending agent is prepared by the following steps: dissolving an effective component of clothianidin in oil, mixing with a surfactant, carrying out ultrasonic treatment in an iron solution to form a micro-emulsion, sequentially adding tannic acid and soybean meal protein isolate, and carrying out secondary coating on clothianidin, so as to obtain the clothianidin-containing seed treatment suspending agent. And finally preparing the seed treatment suspending agent containing clothianidin with an auxiliary agent. Effective components such as clothianidin and the like are subjected to secondary wrapping, the wrapping performance is good, the clothianidin and the like are mixed with seeds, the slow release performance is good, the time for reaching a target part can be consistent with the cymbal growth period of pests, the pests in the plant growth period are effectively removed, amino acid in soybean meal protein isolate is absorbed by plants, tannic acid is assisted to relieve stress response generated by pesticides, and the yield of the pesticides is increased. Amino acid and iron ions contribute to promoting plant growth, and through compounding of the insecticide and the bactericide, the control effect is improved, the dosage is reduced, so that the cost is reduced, and the environmental pollution is alleviated.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation, in particular to a seed treatment suspension containing clothianidin and a preparation method thereof. Background technique [0002] The target of clothianidin is the nicotinic acetylcholine receptor in the nervous system of insects. It has contact killing, stomach poisoning and systemic activity. It has the characteristics of high efficiency, broad spectrum, low dosage, low toxicity, long-lasting effect of pesticides, and no cross-resistance with conventional pesticides. Its novel and special molecular structure endows it with better performance than traditional neonicotinoid insecticides, and has the potential to become a large-scale insecticide worldwide. [0003] The use of seed dressing spraying method for pest control can effectively reduce labor input, save costs, and at the same time reduce environmental pollution and protect natural enemies. Therefore, in production pract...
