What herbicide does not affect the lawn?

First of all, it is necessary to make clear the types of lawn weeds. Broadleaf weeds can be removed with 2,4-D and tribenuron-methyl, and Cyperaceae can try atrazine, but the dosage needs to be tried.

Gramineae weeds in lawn are difficult to be selectively weeded because of their close genetic relationship.

Warm-season lawns in northern China generally turn yellow in winter and germinate in spring. If the lawn has been planted, consider applying pendimethalin EC with high safety as far as possible before spring sowing, and the dosage per mu should not exceed 80ml. The method can inhibit the seed germination of annual gramineous weeds and broadleaf weeds. The residual weed seeds in the soil are eliminated, and the lawn has permanent roots, which has little impact.

After the lawn is green, it should be further controlled by 2,4-D.

At the same time, most grass species are resistant to cutting, which can increase the frequency of lawn maintenance. Frequent mowing will make most broadleaf weeds unable to survive.
