Problems solved by technology

[0007] Because oxyflufen is more effective in controlling broad-leaved weeds than broad-leaved weeds, the control effect on grassy weeds such as barnyardgrass with high leaf age is slightly worse, and the field duration is slightly shorter than that of broad-leaved weeds

Abstract

The invention discloses a paddy field weeding composition containing oxyfluorfen and pyraclonil, and relates to the technical field of agricultural weeding. The paddy field weeding composition comprises an effective quantity of active components, auxiliaries and excipient. The active components include the oxyfluorfen and the pyraclonil. Compared with single dosage, the paddy field weeding composition prolongs the pesticide application suitable period and widens the functional spectrum; an excellent prevention and killing effect is achieved on paddy field swart weeds such as barnyard grass, moleplant seeds and sagittaria pygmaea which cannot be prevented and killed easily; annual broadleaf weeds, sedge weeds, grassy weeds and certain perennial weeds can be killed at the same time. Besides, the lasting period is long, safety can be achieved by paddies and next-stubble crops, and thus the paddy field weeding composition is an ideal paddy field weed killer.

Description

Technical field: [0001] The invention relates to the technical field of agricultural weeding, in particular to a paddy field herbicidal composition containing oxyfluorfen and dipacenil. Background technique: [0002] Rice is one of the main food crops in my country, and it ranks first among the food crops in my country regardless of the planting area and output. There have always been a large number of weeds in the paddy fields of all rice-growing areas in my country. According to statistics, there are more than 200 species of weeds that can cause harm in paddy fields across the country, of which more than 40 are the most common, widespread, and serious. Various rice cultivation methods include transplanting, seedling throwing and direct seeding, so that the types of rice weeds continue to increase, the occurrence period is prolonged, and the damage is aggravated. [0003] In recent years, simple and long-term application of a weed control method (agricultural or chemical)...
