Background technique

Grub is one of the common pests that harm grape plants. It is the larva of the golden tortoise shell, also known as white soil silkworm. Grubs generally harm agricultural crops and economic crops. They like to eat freshly sown seeds, roots, tubers, stems and seedlings. They are worldwide underground pests and cause great harm. When grubs harm grape plants, they mainly bite off the seedlings or chew on the roots of the seedlings, causing broken seedlings or hollow roots. The damage is the most serious in spring and autumn.

The method of killing grub mainly contains four kinds at present: (1) biological natural enemy control method: this method effect is unsatisfactory, and the shortcoming such as cost height, effective slow and production is difficult to popularize. (2) Chemical pesticide root irrigation method: This method is easy to pollute crops, thereby producing various "poisonous food", which directly endangers people's life safety. Pollution of the growth environment of the next crop will prevent the production of organic vegetables and other crops. With the increasing use of pesticides, environmental pollution is becoming more and more serious.
