Rice leaf roller is a common pest found on rice plants. Its larvae damage the leaves, causing them to curl, wither, and wilt. Severe infestations can significantly impact rice growth and yield. Furthermore, the physiological damage caused by the rice leaf roller reduces rice plants' ability to resist diseases, making them more susceptible to other pests and pathogens.
The high temperatures and humidity during summer provide suitable conditions for the activity and reproduction of the rice leaf roller. To effectively control the damage caused by this pest, it is recommended that growers proactively manage water and fertilizer in the fields and monitor and prevent pest and disease infestations.
Implement preventive measures:
This includes clearing away straw and weeds, which are conducive to pest breeding, and maintaining clean inter-row spaces to minimize the reproduction and spread of pests such as the rice leaf roller.
Select high-resistance rice varieties:
Choosing high-resistance rice varieties can fundamentally reduce the incidence of pests, lowering the costs of pest control and risks.
Apply fertilizers scientifically and reasonably:
Excessive fertilizer application in rice leads to excessive growth, creating favorable conditions for pests like the rice leaf roller to multiply. Therefore, fertilization should be based on actual conditions and applied appropriately.
Regularly inspect the pest situation:
As the rice plants grow, it is necessary to regularly survey the rice fields. During the peak hatching period of rice leaf roller, it is recommended to apply the pesticide Rebuild at a rate of 500-600 g/ha for foliar spray or drone application to ensure healthy rice growth.
Rebuild（Emamectin benzoate 1.5% + Indoxacarb 7.5%）
