Rice leaf roller is a common pest on rice, mostly occurring from early to mid-July to mid-August. Its larvae can harm the leaves, causing the rice leaves to curl, dry out, and wilt, and in severe cases, it can affect the growth and yield of rice. In addition, the damage caused by rice leaf roller to rice can reduce its disease resistance, making it more susceptible to other pests and pathogens.
The high temperature and humidity in summer are conducive to the activity and reproduction of rice leaf roller. In order to effectively curb the harm of rice leaf roller, it is recommended that farmers do a good job of field water and fertilizer management and pest and disease monitoring and prevention in advance.
Measures for prevention and control of rice leaf roller:
1. Implement preventive control.
This includes cleaning up rice straw and weeds and other plants that are prone to breeding pests, keeping the rows clean and tidy, to reduce the breeding and spread of pests such as rice leaf roller.
2. Choose high disease and pest resistant rice varieties.
The selection of high disease and pest resistant rice varieties can fundamentally reduce the incidence of pests, reduce prevention and control costs and risks.
3. Fertilization should be scientific and reasonable.
Excessive fertilization of rice can lead to excessive growth, which can further create conditions for the large-scale reproduction of pests such as rice leaf roller. Therefore, fertilization should be done reasonably according to the actual situation.
4. Regularly check for pests and deal with problems in time.
As rice grows and develops, it is necessary to regularly inspect the fields. During the peak hatching period of eggs, use the pesticide - Echolo at a rate of 500~600ml/ha for foliar spraying or drone application to ensure the steady growth of rice.
