When is the best time to use herbicide? Weather change is crucial!

As long as the family has friends who grow cultivated crops in the field, they must be no stranger to herbicides. The necessary weeding work should be carried out at all times of the year to create a clean environment for fruits and vegetables. Weeds grow fast in summer and there are many in winter, which is really a headache. So do you know when it's best to use herbicide?

When is the best time to use herbicide?

The fight against herbicides mainly starts from several aspects, first of all, the weather:

1. Sunny day

When it is sunny and hot, it is recommended that you go after 4-5 o'clock in the afternoon, when the sun fades slowly during the day, and weeds will be eliminated to a certain extent after overnight absorption. Some friends may wonder why they don't call in the morning, after all, the temperature is low in the morning. In fact, weeding is not recommended in the morning. It takes a process to absorb the herbicide solution in the morning (usually about five to six hours). Before the weeds are fully absorbed, when the sun comes out at noon, the sun will accelerate the evaporation of the herbicide liquid. In this case, the amount of herbicide solution absorbed by weeds is reduced, and the weeding effect is not very good.

2. Cloudy days

When using herbicides on cloudy days, we should pay more attention to the rain. There is no direct sun in cloudy days, so the evaporation rate of herbicide solution is not as fast as in sunny days. However, it is mainly necessary to refer to the temperature of the day. If the temperature is high on a cloudy day, it is recommended that you take herbicides in the afternoon. If you want to take medicine in the morning (in the case of dew), you can also take medicine, the main reason is also similar to sunny days.

In fact, whether it is sunny or cloudy, the editor does not recommend that everyone take medicine at noon. In addition to the above factors, high temperatures at noon can easily cause heatstroke. At noon a person went to the field to weed, in case of heatstroke, it is still very dangerous.

Then there is the reason for the planting object, which is divided into retail investors and large investors:

1. Retail investors

Retail is what we call individual cultivation, retail herbicide is mainly a principle, it is not recommended to carry out at noon. And if the planting area is relatively large, it is best to do it every day, and don't think about doing it all in one day, which has little impact on the crops.

2. Large households

Large households mainly refer to co-operatives, farms and other collectives, and large households generally employ hourly workers to pay their wages according to the number of days, so that they can be managed effectively. If it is calculated according to the number of days, it will certainly not be cost-effective to play again in the afternoon. Therefore, in view of this situation, we also have to deal with it dialectically, and we can avoid the hottest time at noon.

With regard to the time of weeding, the editor will introduce you here today. Weeding has to be suitable for the land, and the most correct way will be followed.
