The wheat weeds in the region have to see Amanita, chickweed, Polygonum, vetch, spicy vegetables such as more than a dozen to see Amanita, the most serious damage to the chickweed.According to the three wheat high yield community survey, seedling per foot Amethyst to see the occurrence of 100 to 300 strains, equivalent to 60 to 800,000 per acre, serious field plots 300 to 800 per foot, and per acre 180 to 480 million, 10 to 30 times the wheat seedlings. , The general field of fresh weight per acre 850 ~ 1100 pounds of grapes, serious up to over 2000 pounds of field above the general grass damage Tianmai about 10% loss of about 60 pounds per acre; serious field loss of 2 to 4 into , Less per mu received 100 ~ 240 kg.A comprehensive prevention and treatment approach is:
