Control method of thrips pest

There are three methods to control thrips pests, which are agricultural control, physical control and pesticide control. Agricultural control should remove weeds in the field and reduce the source of insects. Physical control can be trapped and killed with a blue board. Drug control can be carried out with 48% Lesbon 2000 times, or 2.5% Caixi (doxorubicin) suspension 1000 times, or 48% polymycin (such as propofol) 5000 times, or 6% ethyl doxorubicin (such as Elushi) 1000 times.

1. Agricultural prevention and control

Remove weeds in the field and reduce the source of insects. Strengthen the management of water and fertilizer to make the plant grow healthily.

two。 Physical prevention and cure

The trapping and killing of blue board in the field is consistent with that of yellow board, and it is suspended between crop rows, which is high at or slightly higher than the growing point, with 30 to 40 pieces per mu. According to the number of insects in the field, the pests on the blue board can be cleaned up in time to achieve the best control effect. Because thrips have a strong tendency to blue, using this feature, thrips can automatically fly to the blue board, adhere firmly, so as to achieve insecticidal effect.

3. Chemical control

When the number of insects per plant is 3-5, it should be sprayed to control. You can use 48% Lesbon 2000 times, or 2.50% Caixi (doxorubicin) suspension 1000 times, or 48% doxorubicin (such as propofol) 5000 times, or 6% ethyl doxorubicin (such as Elvis) 1000 times. The spray was started from the seedling stage and was sprayed once every 5-7 days. It can also be sprayed with 1000 times of 20% permethrin EC or 2.5% bifenthrin 1000 times + 70% imidacloprid 5000 times, once every 7 to 10 days, for 2 times in a row.
