Weather forecast of Lushuihe town

Dew, medicine and medicine are also arguing endlessly on this topic. Some friends think that it is more effective to spray any pesticide after rain or when the dew is wet. Some friends think that the exposure is too big, and the application effect is not good. What is it actually like? If a closed herbicide is used to kill the herbicide at this time, there will be no dew and dew. Mainly to seal weed seeds and young roots. The method has the advantages of moderate dosage, good sealing performance and basically no weeds in the later stage.

At present, most of the closed herbicides on the market work through the bud absorption of weeds, and the roots are rarely absorbed. After rain or dew, it is easier to penetrate into the soil after spraying herbicides, and the effect is better. Be careful not to use herbicides in hot weather. Herbicide can't get into weeds in high temperature weather. It can't play the role of weeding with the evaporation of temperature, so you must look at the weather forecast and choose a good weather before using it to achieve the ideal weeding effect. Theoretically, the higher the temperature, the better the herbicide effect, but the higher the temperature, the faster the herbicide evaporates and the lower the efficacy.

Herbicide sealed in advance can be sprayed after dew or dew is dry, and the herbicide is the best when there is no dew in the later stage. Weed absorbent works well in high weather, but the higher the temperature, the faster the fog medicine evaporates, which will affect the efficacy. Therefore, we should pay special attention to the weather forecast and do our homework before applying pesticide to lay the foundation for a bumper harvest.

In this period of using closed herbicides to kill herbicides, even if there is dew, there can be no dew. Mainly to seal weed seeds and young roots. The method has the advantages of moderate dosage, good sealing performance and basically no weeds in the later stage. Pay attention to avoid high temperature weather, the evaporation of drug concentration will reduce the efficacy. Herbicide after seedling should be avoided at night after rain or before morning dew. Be careful not to use herbicides in hot weather. Herbicide can't enter the weeds themselves at high temperature, and it can't play a weeding role with the evaporation of temperature, so it depends on the weather forecast and choose good weather before using it, in order to achieve the ideal weeding effect. Theoretically, the higher the temperature, the better the herbicide effect, but the higher the temperature, the faster the herbicide evaporates and the lower the efficacy.

The application method of herbicides in actual planting can not be limited to theory, nor can it be completely divorced from theory. According to many years of personal planting experience, dew may not form in the later stage except for the herbicide. Generally, after 7: 00 am, before 9: 00 am and after 5: 00 pm, the application effect is obvious during this period. Herbicides burn well in the absence of dew, and they burn well when dew is dry. In the actual process of drug injection, using herbicides such as hay is more effective than without dew.
