Is there any way to control the ginger heart borer?

Is there any way to control the ginger heart borer? Please introduce the method when the ginger grows to about 20 cm, the first generation of heart drills begin to harm, the newly hatched larvae first harm the tender leaves, to the 3rd instar begin to decay, mostly in 2-3 nodes, often causing heart leaf wilting or the whole plant withered. The stem decay of the second generation of drillers was mostly in the middle and upper parts, especially in the middle. At present, most of the borer in the ginger field are eggs and 1-2 instar larvae, which have not yet entered the stem. The drillworm likes medium temperature and high humidity, and high temperature and drying is disadvantageous to its occurrence, especially when the ginger plant grows to 50 cm, Jiang Tian Yu closes the high humid environment, which leads to serious insect pests, so the prevention and control of drillworm should be carried out earlier. The prevention and control of drillworms can be prevented by planting trapping crops around ginger fields, which not only harm ginger, but also harm corn, sorghum and other crops. According to this characteristic, trapping crops can be planted around the ginger field purposefully, and chemical control or retting fertilizer can be removed after the adults lay eggs. At the same time, pay attention to the planting density of ginger field, remove the old and rotten leaves in time, and reduce the humidity in the field. Chemical control should be carried out in time, spraying plants with insecticides before entering the stem, and foliar spraying with cypermethrin, methamyl salt and phoxim can be used to control the damage of drillers into the stem and increase the difficulty of control.
