Li Dongzhen, Lintong District, Shaanxi Province, via SMS (137****7109) August 1 Q: After the corn field used Yu Nongsi, it is now at the heading stage. There are grasses in the field. How can I control it? Wang Zefeng, Product Manager of Cornfield, Shandong Shengbang Greenfield Chemical Co., Ltd. Answer: There are still weeds in the corn field. It is recommended that paraquat should be sprayed with a spray hood, and the nozzles should be pressed down and directed between the rows. This has no effect on the aftermath. As long as you pay attention not to spray liquid corn plants, there is no effect on the normal growth of corn. It is not advisable to choose other agents because other agents have a risk of injury to corn and the cost will be higher for farmers. Given the current growth of corn, as long as paraquat is sprayed on barnyardgrass, after the death of the aboveground parts, the leaves of corn plants can block the sunlight, and many weeds under the corn will not grow at all, so it will not affect the corn yield.
