The safety period of chemical herbicides on sugar beets depends mainly on the degradation of certain herbicides in the soil. The rate of degradation of chemical herbicides in soil is related to climate (mainly temperature), soil organic matter content, pH, and moisture. The safety period of several commonly used herbicides for beets is now described as follows:
Pu Shite: The special herbicide for Bean Field has a long residual effect in the city and is particularly sensitive to crops such as sugar beet. The herbicide degraded slowly and remained in the soil for 36 months, during which time sugar beet could not be grown.
Bean sulfonate: Bean field herbicide, when the soil pH value is less than 1.5, the herbicide has a degradation period of 24 months in the soil, and can not grow sugar beet during this period.
Chlorsulfuron: a wheat field herbicide. When the soil pH is less than 6.5, the herbicide has a degradation period of 24 months in the soil.
Saecco and Atrazine: Cornfield herbicides, when used at a dose of more than 4 kg per hectare, cannot be grown for 12 months.
