Suspended seed coating agent for preventing and controlling diseases and insect pests in corn seedling stage

Abstract

The invention relates to the field of pesticide preparations, disclosed a suspension seed coating agent which comprises the active components chlorantraniliprole and thiram and has the effects of killing insects and preventing diseases. The seed coating agent is characterized by being composed of the following compositions in percent by weight: 3.0-20.0% of chlorantraniliprole, 4.0-12.0% of thiram, 1.0-4.0% of tebuconazole, 2.0-4.5% of a wetting dispersant (prepared by compounding pesticide emulsifier 34 and HY-2), 0.1-0.5% of a thickening agent, 0.1-4.0% of a film forming agent, 3.0-5.0% of an antifreezing agent, 0.1-3.0% of an aposematic agent, 0.1-1.0% of an antifoaming agent and the balance water. The seed coating agent provided by the invention has the characteristics of being convenient to prepare, uniform in coating, low in shedding rate, high in efficiency, low in toxicity, relatively safe to environment and the like, and has substantial control effect on corn seedling-stage insect diseases such as sphacelotheca reiliana, ustilago maydis, stem rot, cutworms, athetis lepigone, grub and the like, the control effect on corn seedling-stage insect diseases reaches 90% or more, and the persistent period reaches about 2 months.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a suspended seed coating agent for preventing and controlling corn seedling pests. Background technique [0002] Corn is one of the main food crops in my country, and it is also a very important feed crop. The serious occurrence of diseases and insect pests is the main factor restricting the production of corn, which not only causes great economic losses to the corn planting industry, but also has a relatively large impact on the breeding industry. big impact. The frequent occurrence of pests and diseases in the corn seedling stage caused serious seedling shortage and affected the uniformity. [0003] Seed coating agents have multiple effects such as preventing and controlling seed-borne, soil-borne and seedling pests and rodents, as well as protecting and strengthening seedlings. Seed coating technology has been widely used in developed countries abroad. The characteristic o...
