Abstract
The invention discloses a seed treating agent and a special pesticide composition thereof. The special pesticide composition disclosed by the invention comprises thiamethoxam and pyraclostrobin, wherein the mass ratio of thiamethoxam to pyraclostrobin is (1-10):1; the seed treating agent is prepared from the pesticide composition and an additive, specifically 10-40 percentage by mass of thiamethoxam, 1-15 percentage by mass of pyraclostrobin and the balance of the additive; the seed treating agent is a suspended seed coating or a seed treatment microcapsule suspension-suspending agent. The pesticide composition can be used for preventing and controlling insect pests with piercing sucking mouthparts like aphides, lygocoris lucorum and thrips in the cotton vegetable stage and cotton rhizoctonia, and can reduce times for spraying; the seed treating agent not only can be used for preventing and controlling insect pests with piercing sucking mouthparts like aphides, lygocoris lucorum and thrips in the cotton vegetable stage and cotton rhizoctonia, but also has the functions of improving the emergence rate of cotton, maize and peanuts and promoting the plant growth.
Description
technical field [0001] The invention relates to a seed treatment agent and a special pesticide composition thereof, belonging to the technical field of pesticides. Background technique [0002] Cotton blight occurs in all major cotton areas in my country. The bacteria can be spread by soil and seeds. After infection, the disease develops quickly and can continue to infect the surrounding cotton seedlings. After the disease occurs, the control effect is often poor. , so protective application is an effective measure to control the disease. Regarding insect pests in cotton fields, with the increase in planting area of insect-resistant cotton, piercing-sucking mouthparts such as cotton aphids and miridae have replaced cotton bollworms as the main pests in cotton fields, seriously affecting the yield and quality of cotton. By increasing the frequency of spraying to control pests, this control measure not only increases the cost of control, but also increases the amount of labo...
