Matters needing attention in weeding wheat before winter

Weeding before wheat overwintering has many advantages, first of all, the cost is low, and then spraying chemicals in winter, the exposed area of weeds is large, which is conducive to weeds to absorb more agents and obtain better weeding effect. And the earlier weeding, the more conducive to the growth and development of wheat, conducive to the formation of strong seedlings, but weeding before winter should also pay attention to several misunderstandings, let's take a look.

Before weeding, the first thing is to choose agents, targeted selection of the corresponding agents, in order to get twice the result with half the effort. For example, for wheat fields dominated by broad-leaved weeds, we can use kanmifen dry suspensions or benzenesulfuron series product wettable powders, while for gramineous weeds, choose oxazolidin water emulsion or Shima oil suspensions.

2. Choose the correct spraying time

When to spray is also a subject of knowledge, to do three look, one look is the emergence of seedlings. The seedlings have a certain shade tolerance to herbicides in the 3-4 leaf stage, when spraying can ensure the safety of wheat seedlings, and there are few tillers of wheat at this time, which is beneficial to the absorption of weeds and avoid spraying at low temperature as far as possible. Second, look at soil moisture, if soil moisture is poor, we must increase the amount of water when applying pesticides; third, depending on the weather, try to choose the weather when the temperature is stable at 8-10 degrees and there is no wind and rain.

3. Do the second dilution well.

The herbicide in the wheat field must be diluted twice. First, it should be diluted evenly with a small amount of warm water in a small container. After adding enough water into the medicine, the herbicide can be sprayed, otherwise it will appear the phenomenon of tattoo.

4. Do not leak or re-spray

Before spraying the medicine, it is necessary to do a good job in the inspection and maintenance of medicine and equipment, ensure its normal operation, resolutely put an end to dripping, leakage, blocking and other phenomena, and operators should move forward at a uniform speed to prevent leakage or re-spraying.
