Use post-emergence herbicides with caution
In view of the time and energy saving of postemergence herbicides, the use of postemergence herbicides has been greatly promoted in recent years. The people have already known this medicine and used it. Although it has been used for many years, the use of post-emergence herbicides is still inadequate. Each year will cause some problems for ordinary people. In fact, when our technicians mentioned this issue every time they went to the countryside, they could not afford enough attention so as to cause losses to themselves. According to past experience, there are mainly the following misuses: 1, spray too heavy. Excessive use of the amount caused corn seedlings not to grow yellow. Some cherishing water does not hesitate to take drugs. While ensuring the dosage of mu, it must increase the amount of water used. The amount of liquid used for mu should not be less than 40 kg in order to achieve an ideal control effect. Can not be too high concentration. 2. Blending organophosphorus pesticides. Herbicides are written on bottles that cannot be mixed with organophosphorus pesticides. However, some people do not look closely to buy medicines and use them blindly, causing damage to themselves. Single medication must be separated by more than 7 days; at the same time, avoid imidacloprid or acetamiprid agents, although the two drugs are not organophosphorus pesticides, if mixed with sprayed leaves, it is easy to produce phytotoxicity. 3, sensitive corn varieties can not spray post-emergence herbicides. For example, Shiyu No. 7 and Shiyu No. 7 seed bags can not use post-emergence herbicides, but they are still used, causing corn crops to fail to produce. So the slogan of scientific farming is not shouting. The people must farm in science. Only in this way can they produce high returns and harvests. With science and efficiency, the people must realize this. Not only the people, but also some agricultural resources dealers must improve their business standards. They must be careful and patient with the people. Only in this way can we win-win in order to guarantee a bumper harvest every year!
