The safe use of wheat herbicides is a very important issue. Next, we will share some tips and methods for the use of wheat herbicides. We hope everyone can safely use them.

Farmers need to make final guarantees on the efficacy of herbicides in terms of their medication technology.

First, farmers should pay attention to the timing of drug use.

There are two problems in the choice of medication time. The first problem is that the farmers want to wait until all the weeds are out and apply again. In fact, this is a misunderstanding. From the perspective of common sense, “October confinement” is a certain number. The unearthed ones after that year should not wait until the weeds before the frost become “fine”. The second is the restriction of soil moisture, which is similar to the frequency of rainfall and rainfall after mid-to-late June 2011 to mid-to-late September. This indicates that the application of wheat field herbicide before the winter of 2012 will become a critical time. On the contrary, if the winter is dry, weeding before winter is not particularly critical. For example, before the winter drought in 2011, many farmers did not apply their medicine. Today, the author gives a reference standard for pesticide application in drought years. That is, if the wheat seedlings in the morning are exposed to heavy dew, indicating that soil moisture is acceptable, the pesticide can be applied.

Second, the correct use of medication and water consumption. In fact, this is a basic issue that is also a commonplace problem, but it still needs to be emphasized. First, farmers have drug use inertia. For example, in order to ensure the effectiveness of insecticides and fungicides, they need to add a large number of doses outside the technical recommendations. Herbicides, however, cannot do this for the simple reason that pests and crops are two species. However, wheat and weeds are closely related to each other and are prone to phytotoxicity. Second, the problem of water consumption, generally all herbicides require two barrels of water (ie, about 60 pounds). In practice, many farmers prefer to use a bucket of water ( About 30 pounds or less, imagine, can this guarantee efficacy?

Third, the restrictions on the external conditions of spraying are lifted to improve the efficacy of the drug. One of the peripheral conditions is the application of temperature, this issue does not seem important, but the author often received a telephone call asking the temperature of the application. Farmers must pay attention to the fact that there are not many species applied at low temperatures, for example, such as metamphidicarb can be applied below 5°C, and other products are required to apply above 8°C, especially for inosoxim. Amine compound products should be applied at the temperature of another component, that is, above 8°C. The second problem is the use of medical devices. With the increase in the cost of labor, the use of highly effective spraying devices has been put into use. Especially when the amount of water does not meet the requirements, many people feel that the effect of mechanical spraying and weeding is less than that of manual weeding. As a result, under the premise of increasing labor costs, it is impossible to require no spray equipment. The most effective way is to ensure the amount of water. The third is not to re-spray or spray.

Fourth, high-value-added crop rotations are very important for safety. This type of crop is especially high value-added crops such as peanuts and peppers. Do not use sulfonylurea herbicides such as tribenuron-methyl as much as possible. The author believes that even if some of the weeds are rebounded (such as a rebound rate of less than 8%), such as the use of oxazolium oxalate and 2a-4-chloro- compound products, it is always a hundred times more powerful than the lower jaw. In other words, the safety of squatting is more important than the rebound of some weeds. In order to ensure the efficacy of this type of herbicide, please pay attention to the basic conditions of clear windlessness and water consumption of not less than 60 pounds per mu. It is recommended to use a special product for the Longsheng wheat field. The product is highly safe and can be used throughout the growing period of wheat.
