A herbicide that does not harm tobacco

Weeds are overgrown, and they seem to compete with tobacco in the field, which is no stranger to tobacco growers. At this time, the quickest and convenient way is to use tobacco field herbicides to control weeds in the field. So what are the herbicides that don't hurt tobacco?

Herbicides that do not harm tobacco

Herbicides that do not harm tobacco include Metolachlor, Diachlor, Quine, Pyrrolofen and so on. As long as they are used according to the instructions of the herbicide, they will not harm tobacco. Among them, Metolachlor is also called Duer, and its best application time should be carried out before weed germination, because it is mainly absorbed by young buds and transmitted upward, thus inhibiting the growth of buds and roots, which has a good effect on the control of annual Gramineae weeds.

1. Diachlor is a selective pre-bud soil treatment agent, which is also suitable for weeding in tobacco field. after absorbing the solution, weed roots and coleoptiles inhibit cell division and protein composition, so that root growth is affected and heart leaves curl and die. If the pesticide is used under the condition of dry soil, the control effect is poor, so it should be irrigated when the soil is dry or the soil is dry.

2. In the national pesticide classification standard, quinofop is a low toxic herbicide, and it is a good herbicide for tobacco field. It is absorbed by weed stems and leaves, conducts up and down in both directions, accumulates at the top and intermediate meristem, inhibits cellular fatty acid synthesis, makes weeds necrotic, the action speed of quinofop is fast, and the efficacy is relatively stable. Rain Water's environmental conditions such as temperature and humidity have little effect on it. It has a good effect on Gramineae weeds in broad-leaved crop field.
