What pesticide is effective for controlling rice midges?

Rice midges are a common insect pest of rice. The main harmful species are the yellow, black, and green rice midges. So what pesticide should be used for rice midges to control them?

1. Main damage caused by rice midges

Rice midges breed larvae in large numbers in rice fields, severely affecting the development of the rice root system. Rice midge larvae damage the young roots and young shoots of rice, causing rice seedlings to float. Rice midge larvae also feed on the embryo and endosperm of ungerminated rice seeds, so the seeds cannot germinate, and the rice crop suffers severe losses.

2. What pesticide should be used for rice midges?

1. You can use 10-15 grams of 90% crystallized trichlorfon, add 10-15 kg of water, stir well, and spray it into the rice field when the water depth is about 4 cm;

2. Or use 5% phorate granules for control, with 1 kg per mu, mixed with 15 kg of sandy soil and broadcast.

In addition, after draining the field water, wait one day, hang a small bag containing trichlorfon at the water inlet for irrigation, and when the irrigation water reaches 3-4 cm deep, stop irrigation and block the water inlet. Keeping it this way for 12 hours can also kill rice midge larvae.

3. Other control methods for rice midges

Rice midges can also be controlled by agricultural methods. Rice seedlings can be covered with plastic film and transplanted appropriately early, which can also reduce damage from rice midges. You can also drain the field and dry it in the sun for 2-3 days, so the larvae will dry to death, further suppressing the damage from rice midges.

Besides rice midges, rice also has many other pests:

1. Exogenous pests, such as brown planthopper, white-backed planthopper, rice leaf roller, armyworm, etc.

2. Endogenous pests, such as yellow stem borer, striped stem borer, pink stem borer, small brown planthopper, rice thrips, etc.

These pests all need to be controlled. Only by solving these pests and diseases can rice grow normally, and the yield will not be greatly affected.
