At present, the winter rapeseed in our province is about to enter the sowing stage. Once the oilseed rape emerges, it will be harmed by various pests. It is very important to prevent and control seedling pests. Yellow stripe jumps: Adults bite leaves into dense holes, causing rape seedlings to stop growing or die. The larvae feed on the roots and, in severe cases, can leave the entire plant yellow and die. The prevention and control method is as follows: 90% crystal trichlorfon is sprayed 1000 times to prevent adult insects, or 1000-2000 times liquid is rooted to prevent larvae. Locust: Use 10% gold fear 1500 times liquid, or 75% sharp first 1000 times liquid foliar spray.
