2, the impact of wheat stubble. At present, most of the wheat fields are harvested mechanically, and the wheat straw wheat stalks are all scattered in the field. The height of the wheat stalks is generally about 20 cm, and the corn is sown without cockroaches. The herbicide sprayed on the wheat stalks and wheat stalks are mostly adhered to the soil. Surfaces and weeds receive less liquid and do not act to close the ground and kill grass.
3. Drought effects. Summer corn sowing period is high temperature season, more drought and less rain, the herbicide evaporates quickly after spraying herbicide, it is difficult to form a film on the surface, high temperature and drought also hinder the delivery and conduction of the agent in the weed body, affecting the normal effect of the drug. Play.
4, the drug is late. At present, the herbicides in corn fields that have been promoted are mostly used in the control of weeds before the 5-leaf stage. However, due to various reasons, the control period is missed, causing the weeds to grow up and the resistance to herbicides to be enhanced, resulting in poor control effect.
5. The grass is left in the wheat field. The control of weeds in some wheat fields is not complete, resulting in the weeds growing up to the corn field. Generally, the special herbicide for corn has no control effect on this, and some grasses have no control effect.
6, the amount of liquid is small. Many farmers save labor and labor. When spraying herbicides, the amount of water added is too small. Generally, about 15 kilograms of liquid per acre is used, which does not form a film on the ground, thus affecting the exertion of the efficacy.
7, improper application methods. One is that the suspending herbicide is used without being sufficiently shaken, which affects the herbicidal effect. The second is to use the forward-style spraying method, so that the liquid that has just been sprayed to the surface is trampled or stuck away when the film has not been formed, so that the foot part continues to grow grass. The third is that the spraying is uneven, there is a phenomenon of leakage or re-spraying, and the grass is continued without spraying the medicine. Fourth, it is sprayed around noon in fine weather, and the liquid evaporates quickly and the efficacy is low. The fifth is the use of windy days, some pesticides fall into the field, and the effective dose is reduced. Thereby affecting the effect of controlling weeds.

1. The drug selection is not accurate. Because the peasant masses are unclear about the types of weeds and the herbicide-killing objects, they cannot apply medicine to the grass, causing some weeds to have poor or no control effect.
