Problems solved by technology
Therefore, corn spider mites form the peak period of damage from late July to mid-August. During this period, the main method of prevention and control is to spray high-efficiency and low-toxicity acaricides in the corn field. However, after the corn enters the closure period, the corn plants are tall and the coverage is high. , the field temperature is high, spraying pesticides brings great difficulties to operators, and it is easy to cause pesticide poisoning incidents. In addition, farmers are busy harvesting summer crops such as wheat, sunflower, and potatoes at this time, and have no time to take care of the control of corn spider mites.

Abstract
The invention discloses a fumigation agent for control corn spider mite. The effective component of the fumigation agent is composed of any two of methyl pirimiphos, dichlorvos, and pyridaben according to the weight ratio of 1:2 to 2:1. The controlled effect on the corn spider mite is prominently improved after the compounding, and the effect is better than that of single component. The fumigation agent is applied through a poisonous soil method, the leaf mites on the lower part of a corn strain can be rapidly killed, thus the diffusion of leaf mites to the upper part of the corn strain can be controlled, and the corn can successfully pass the tassel period and enter the mature period. The problem that in the prior art during the pesticide spraying process the farmers sometimes are poisoned is solved.
Description
technical field The invention belongs to the field of pesticide applications, and in particular relates to a fumigant for preventing and controlling corn spider mites. Background technique In recent years, with the adjustment of the agricultural industry structure and the continuous development of animal husbandry, the planting area of corn seed production and full-film double-furrow corn planting in Hexi, Gansu has continued to expand, and has become an important source of income for farmers. The development of the characteristic corn industrial belt, on the one hand, increases the competitiveness of Gansu agriculture and promotes the increase in production and income of Gansu agriculture; but on the other hand, it creates extremely favorable conditions for the occurrence and harm of corn spider mites, which leads to the occurrence and damage of pest mites. It is aggravating year by year, seriously affecting the healthy and stable development of the corn industry. Tetran...
