Problems solved by technology
Clomazone is a carotenoid biosynthesis inhibitor. The specific target enzyme is unknown. It is a selective pre-emergence herbicide. By inhibiting the synthesis of pentadiene compounds, it hinders the biosynthesis of carotene and chlorophyll, and passes through the roots and shoots of plants. Absorption, transport upward, and spread to the leaves through the xylem. Although sensitive plants can germinate and emerge from the soil, they will become white seedlings due to lack of pigment and die in a short period of time.

The invention discloses a weeding composition containing pretilachlor and clomazone for lotus root field. The composition comprises two active ingredients and the balance of pesticide adjuvants and carriers, wherein the two active ingredients are pretilachlor and clomazone respectively; the ratio of pretilachlor to clomazone is (1-50): 1; the weight of the two active ingredients accounts for 10%-50% of the total weight of the composition. The composition is prepared into emulsified oil, emulsifiable powder or fine granules.
Description
technical field [0001] The invention belongs to the field of agricultural plant protection and relates to a lotus root field herbicide composition containing pretilachlor and clomazone. Background technique [0002] The chemical name of clomazone is: 2-(2-chlorobenzyl)-4,4-dimethylisoxazol-3-one, which belongs to the class of isoxazolone herbicides. Clomazone is a carotenoid biosynthesis inhibitor. The specific target enzyme is unknown. It is a selective pre-emergence herbicide. By inhibiting the synthesis of pentadiene compounds, it hinders the biosynthesis of carotene and chlorophyll, and passes through the roots and shoots of plants. Absorbed, transported upwards, and diffused to the leaves through the xylem, although sensitive plants can germinate and emerge from the soil, they will become white seedlings due to lack of pigment, and will die in a short period of time. Clomazone currently has preparation products: single doses are emulsifiable concentrates and microcapsu...
