Thiamethoxam is a new structure of second-generation nicotine-based high-efficiency and low-toxic insecticide , and pest insects have good control effect. Recently, China's pesticide network Xiaobian found on the network about the effect of thiamethoxam to control the planthopper, which has received much attention from everyone. Xiaobian also compiled relevant information from the network:
1. The chlorpyrifos and thiamethoxam 30% water emulsion has good control effect on rice planthopper, and the total corrected control effect of the drug dosage of 80mL/667m^2 after 7 and 14d is 90.4% and 86.1 respectively. %, which is equivalent to the control effect of the control agent thiamethoxam 25% water dispersible granule 3g/667m^2, which is obviously superior to the control agent chlorpyrifos 40% emulsifiable concentrate 100mL/667m^2. The agent is not only effective, but also has a long-lasting effect and good safety.
2, 40% chlorantraniliprole thiamethoxam water dispersion granules to prevent early rice pests test, 40% chlorantraniliprole thiamethoxam water dispersion granule compounding agent for the control of rice leaf roller and rice The planthopper has the characteristics of slow quick-acting, long-lasting effect, less dosage and good control effect. On the 10th day after application, the insecticidal effect on rice leaf roller was 99.3%-100%, and the insecticidal effect of rice planthopper was 70.3%-76.7%. After 16 days of application, rice leaf roller was controlled. The effect of curling is 99.2%-99.5%, and the insecticidal effect on rice planthopper is 70.9%-80.5%, especially the insecticidal and control effect of rice leaf roller is better than the local common control. Pharmacy.
3. The field efficacy test of 25% thiamethoxam WG on rice planthopper (Whitebacked planthopper and brown planthopper) was carried out on early and late rice, respectively. The results showed that 2 g/667 m225% thiamethoxam WG was used for prevention and treatment. Rice planthopper has the characteristics of high control effect, long potency and fast insecticidal action.
4. Before the corn was planted, the corn seed was coated with 35% thiamethoxam suspension seed coating agent to investigate its control effect on the corn ash. The results showed that it had good control effect on the corn ash. It has a long-term effect and is safe for corn, which can be widely promoted in corn production.
As for more research academic series, the above information is no longer introduced one by one. The above information indicates that the method of using different chlorothiazide content varies according to different crop periods, and the pesticide network Xiaobian reminds everyone to strictly follow the instructions on the use of pesticides . .
In order to prolong the durability of glass bead and prevent its spallation from paint after extruding by vehicles, these beads are coated with a special coating during the production process to increase the adhesion between glass bead and paint, so that can prolong the durability of glass bead above 20%.(It is usually used for surface treatment of Drop on glass beads).
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
