Abstract

The invention relates to a pesticide composition which is prepared from bicyclopyrone, halosulfuron-methyl and pyridine carboxylic acid herbicide. The pyridine carboxylic acid herbicide is selected from one of aminopyralid and fluroxypyr-mepthyl. The composition is prepared from, by weight, 1-30% of bicyclopyrone, 1-30% of halosulfuron-methyl, 1-30% of the pyridine carboxylic acid herbicide and the balance pesticide auxiliaries. The pesticide composition is reasonable in component, has a synergistic effect on corn field weeds, particularly has an obvious synergistic effect on barnyard grass, purslane and euphorbia helioscopia, enlarges the single-dosage phytocidal range, and reduces weed resistance risks.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic responsive pesticide composition with flumetrazone, chlorpyrazosulfuron-methyl and pyridinecarboxylic acid herbicides as active ingredients, which is suitable for controlling annual weeds in corn fields. Background technique [0002] Bicyclopyrone, a triketone ketone herbicide, is absorbed through plant roots and leaves, and conducts in the body to inhibit hydroxyphenylpyruvate dioxygenase, resulting in the accumulation of tyrosine, plastoquinone and The biosynthesis of tocopherol stops, which in turn leads to a decrease in chlorophyll content, causing the plant meristems to lose chlorosis and cause albino death. It can prevent and control annual weeds. It can be used for pre-emergence soil surface treatment and post-emergence stem and leaf treatment. The residual period in the soil is relatively long. Short, suitable for field corn, sweet corn, silag...
