Can wheat herbicide 0- 10 be beaten?
The minimum temperature of wheat herbicide should not be lower than 0℃, otherwise it will easily cause phytotoxicity. When the temperature rises, herbicides will be used on sunny days. Herbicide can be used when the temperature of wheat field is around 10 degree in spring. The temperature is above 0 degrees at night, and it can be played above 5 degrees on sunny days. When the temperature is above 8 degrees, choose a sunny day without wind. When the average temperature is stable above 6℃, herbicides can be used.
The lowest temperature at night is greater than 0 degrees, and you can play above 10 degrees during the day. When the average temperature is higher than 6℃, the control effect of herbicides is better. Except for a few herbicides (fomesafen, which is more resistant to low temperature), general herbicides are not ideal in low temperature weather. It is best to use it when the daily average temperature is above 8 degrees, and the higher the temperature, the better the weeding effect.
Matters needing attention in using wheat herbicide:
It is forbidden to use herbicides before bad weather such as frost, rain, snow, hail and cold current. Especially before the cold in late spring, we should pay more attention to the weather forecast when using herbicides in winter.
It takes at least 3-5 days to use herbicides when spraying pesticides such as organophosphorus or carbamate in wheat fields, otherwise it will easily lead to yellowing and leaf burning of wheat, because organophosphorus pesticides reduce the ability of wheat to degrade herbicides, and then using herbicides will easily lead to phytotoxicity.
