Last Updated: 2024/11/05, Now it is the season of no-tillage potato harvest in Guangxi. In the no-tillage potato base of Baqiao Village, Shuangqiao Town, Wuming County, Guangxi, the average yield of no-tillage potato reached 25 sand kilograms per mu, which was more than 1.5 times of the national average potato yield per mu. Sun Huisheng, a famous potato expert, said that no-tillage planting covered with straw in Guangxi.

In order to control broad-leaf weeds in potato field, ethoxyflurane, pendimethalin and Acetochlor should be used to seal the soil before sowing. During the growing period of potato, there is no good safe and effective drug to control broad-leaf weeds. In the case of mastering the experience of drug use, we can consider using sulfenesulfuron and herbicide. It is understood that DuPont (Tel: 021-58672488) registered 25% sulfenesulfuron water dispersible granules for the control of annual weeds in corn and tobacco fields. it can be used to control a variety of weeds in the stems and leaves of potatoes, tomatoes, eggplants, peppers and other eggplant crops during the growing period, such as Setaria mandshurica, Setaria angustifolia, Euphorbia angustifolia, paspalum, wild oats and other Gramineae weeds, as well as authigenic wheat seedlings. Broad-leaf weeds such as Oxalis, Chenopodium, Polygonum, amaranth, mustard, Portulaca oleracea, Scutellaria angustifolia, Cyperus and other sedge. It is best to apply the pesticide when the weeds are almost all in the field and are in the stage of 2-4 leaves. In the directional uniform spray between the rows, pay attention to control the height of the sprinkler is lower than the crop growth point, so that the liquid is sprayed right between the crop rows, and the medicine can not be sprayed directly to the crop growth point, otherwise it is easy to cause drug damage. It is recommended to expand the area after a successful trial of a small area.
