Wheat spraying schedule

The middle and late of 1 1 in wheat seedling stage is the key period for weeding. At this time, the grass age is relatively small, the drug resistance is relatively small, and it is easier to control.

The period from late February to early March is also a good time to weed, but at this time the weeds are older and more resistant to drugs. It is necessary to increase the dosage during prevention and control, but it is easy to cause phytotoxicity, so special attention should be paid to the dosage.

Precautions:

1, when the soil is dry, we should seize the opportunity of watering the wheat field and apply the herbicide in time to ensure the efficacy of the herbicide.

2. Most herbicides need a certain amount of soil moisture to exert their efficacy. When the soil moisture content is 40%~60%, it is beneficial to exert their effects.

3. Don't use wheat herbicides in bad weather: using herbicides before and after heavy rain and before the arrival of cold air will affect the weeding effect on the one hand and easily cause phytotoxicity on the other. These are all bad weather, especially if you don't use herbicides for 7 days before the cold in late spring. Pay more attention to the weather forecast when using herbicides in winter.

4. Do not re-spray or miss spraying wheat herbicide: When using herbicide, it must be sprayed evenly. Weeds are treated unevenly where herbicides are missed or sprayed less, and the control effect is definitely not good. Remember not to spray again. Wheat is prone to yellowing and herbicide damage.
