Wheat control is a common problem in weed control in wheat fields.

Currently, only disulfuron-methyl has an ideal control effect on A. japonicus, and only herbicides containing disulfuron-methyl can control A. japonicus.

Methyldisulfuron-methyl, trade name Shima, is a wheat herbicide sold on the market by Bayer Company of Germany in 1996.

It can be used to control oats in wheat fields and look after oats.

Because of the high price, it has been mainly used to prevent and control wheat fields in recent years.

However, because Shima has been used for more than 20 years, weeds have developed strong resistance to it, especially the control effect on A. jesus. According to statistics, it is currently only about 70%.

In addition, disulfuron-methyl is not very safe for wheat during use.

Therefore, when using disulfuron-methyl in wheat fields, you should pay attention to three points:

1. Use time.

After three leaves of wheat, it is necessary to spray and control Aesthesia in time as long as the Aesthesia has emerged.

Because the wheatgrass at this time is young and has poor resistance to pesticides, the control effect is good.

2. Pay attention to the temperature when taking medication.

When using disulfuron-methyl, if the temperature is low, or if the temperature drops below 0 degrees within 7 days after use, wheat seedlings will suffer serious damage or even die.

3. Spray the pesticide evenly, without leakage or repeated spraying.

Otherwise, it will cause phytotoxicity in wheat and affect the growth of wheat.

The safety of disulfuron-methyl is very poor when used on wheat, especially high-quality strong-gluten wheat, which is more prone to phytotoxicity.

Therefore, it must be used strictly according to the technical requirements to achieve the ideal control effect.
