What kind of medicine should be used to remove the resistant gold?

During this period of time, many farmers and growers have reflected that the gold in rice fields is very serious, and many fields have failed to control them, especially in the fields that have failed to control them, and the effect of supplementary treatment in the later stage seems not ideal. Next, I would like to talk about some governance suggestions on the basis of some experience in the industry.

The pre-bud herbicide has a very good control effect on Qianjin, especially the herbicide Prochlor, whose control effect is more than 90%. In the dry live broadcast, the use of closed herbicides such as pendimethalin and butachlor is also very good for the prevention and control of Qianjin. More importantly, pre-budding herbicides are also very effective in controlling sedges, such as propachlor, which has a control effect of more than 90%. Reducing the base number of these weeds is very helpful for weeding in the later stage, and in the later stage, we can reduce the use of antagonistic herbicides with cyhalofoxate, so as to ensure the control effect of cyfluoxetate. In the 4-leaf stage of seedlings, Weidaofu + cyhalofoxate spray can be used to control it, or barnyardite + cyhalofoxate can be used to control it.

Choose suitable herbicides to control Qianjin, avoid mixed herbicides such as pyrimiduron, dimethyltetrachloride, prednisone and cyanofluoxetate.

To avoid high temperature and sunny days, cyanofluoxate needs to be absorbed internally in order to play a role, if the high temperature sun is strong, the stomata of weeds are closed, it is difficult to absorb chemicals, and strong sunlight will also make cyanofluoxate photolysis.
