If the corn is watered after being treated with herbicide, does the herbicide still work? Scientifically, it should be determined according to the interval, and the longer the interval, the better the efficacy of the herbicide. It is best to extend the interval to more than two days, otherwise it may not be effective because the herbicide is not thoroughly absorbed by the weeds.

In addition, there is another big problem, if the interval between the herbicide and the watering time is too short, it may enter the soil after the watering herbicide dissolves, causing damage to the maize root system, resulting in drug damage.

For the closed herbicides currently used in production, the herbicides are used before weeds are unearthed after corn sowing, and the roots will be damaged by pouring herbicides into the ground after watering.

Therefore, the use of herbicides in production must be separated from watering time. However, the scientific development of agriculture still needs to prompt several problems in the use of herbicides. 1. Attention should be paid to cleaning before and after the use of herbicides. 2. Secondary dilution must be used for the use of herbicides. 3. According to the instructions of the herbicide, use the medicine according to the instructions. 4. It is best to install a protective cover in front of the sprinkler to make the liquid spray. 5. Choose the weather without wind to spray medicine. ?

Finally, it is important not to rush to use herbicide spray again until it has been determined whether the herbicide is effective. Avoid drug damage caused by repeated use of drugs due to slow efficacy.

Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
