Abstract

The invention relates to a herbicide composition and a preparation method and application thereof. Active components in the herbicide composition comprise tembotrions and pyroxasulfone in a mass ratioof (1:10):(10:1). According to the herbicide composition, the two active components cooperate, the combined action coefficient is higher than 10, and the synergistic effect on weed control is achieved. The herbicide composition is more excellent in long-acting performance and broad spectrum, the pesticide hazard to crops can be reduced, and compared with a herbicide with a single active component, the application range is wider.

Description

technical field [0001] The present invention relates to the fields of agriculture and pesticides, in particular to a herbicide composition, its preparation method and application. Background technique [0002] The over-reliance and long-term use of chemical herbicides has led to the rapid development of weed resistance, and resistant weeds pose a serious threat to farmland weed control and agricultural development. At present, the types of chemical herbicides on the market are relatively limited, and the continuous use of a single chemical pesticide formulation not only brings serious resistance problems, but also greatly reduces the effective utilization rate of pesticides. Especially some crops such as corn are relatively sensitive to herbicides. If herbicides are not applied properly, phytotoxicity often occurs. For example, Tembotrione (Tembotrione) belongs to the HPPD (4-hydroxyphenylpyruvate dioxygenase) inhibitory herbicidal components, but the time limit for the use...
