The control of weeds in the lawn is manually removed, chemical weeding, etc., but in chemical weeding spray herbicides, the impact on the surrounding environment (air, soil, etc.) and turf quality should be considered to avoid unexpected losses. Here are a few herbicides that should not be sprayed on the lawn.
1. Herbicides with long residual period, including chlorfenapyr, sulfonylurea, metsulfuron-methyl, tribenuron, etc., heterocyclics such as chlorhexidine, etc. These herbicides are in the soil. The residual period of the herbicide is longer. After 2 to 3 years, the grasses of the bluegrass will not germinate. If the tall fescue is sprayed on Chengping, it will cause yellowing, whitening and even death of the lawn. .
2. Herbicides in poisoned soils, including valerulone, simazine, and chlorpyrifos. Such spraying of herbicides in the rainy season will directly affect the growth of turf roots. If used continuously, the soil structure will be knotted and deteriorated, which will affect the development of the turf and make the lawn yellow and withered.
Third, the toxic highly toxic herbicides, including sodium pentachlorophenol, paraquat, etc., sprayed with such herbicides, can directly cause damage to the operator's body. The operator's skin is dry, peeling, chapping, and more serious damage to the liver, kidney and other internal organs.
Fourth, the herbicide that produces odor, the lawn is often planted in parks, squares and other places where people are relaxing and entertaining, and fresh air needs to be kept above the lawn. If you use green merlon, it will produce a pungent odor, and if you spray it, it will make the lawn smelly.
In addition, paraquat and Roundup are herbicides that cause the grass to die after spraying, even if it is not in the dormant period of the lawn. Fertilizing equipment can prevent the problem of uneven fertilization caused by human factors.
