Paddy nursery is an important stage of paddy cultivation where the seeds are grown into seedlings that are then transplanted into the main paddy field. However, the nursery is vulnerable to a variety of pests and diseases that can greatly affect the quality and yield of the crop. One of the common pests that affect the paddy nursery is chewing-type insects. In this article, we will discuss the information about the control of chewing-type insect in paddy nursery.
Chewing-type insects are a type of pest that damage crops by feeding on the plant’s tissue.

These practices include using clean seeds, proper spacing of plants, timely removal of weed and regular inspection of the field by the farmer. By following these practices, the chances of pest infestation can be reduced.
In conclusion, chewing-type insects in the paddy nursery are a serious threat to crop yield and quality. Therefore, proper measures must be taken to control the pest infestation. The use of insecticides, planting resistant varieties of paddy, crop rotation, and cultural practices can all help to control chewing-type insects in the paddy nursery. Farmers must take care to choose the right method depending on the severity of the infestation and follow the proper techniques for effective control of chewing-type insects.
