Abstract
The invention discloses a penoxsulam-fentrazamide herbicide composition. The penoxsulam-fentrazamide herbicide composition is used for weeding in the paddy field. In the penoxsulam-fentrazamide herbicide composition, a weight ratio of penoxsulam to fentrazamide is in a range of 5: 1 to 1: 5, and preferably, the weight ratio is 2: 1. Compared with a single-component herbicide, the penoxsulam-fentrazamide herbicide composition obviously improves prevention and control effects, reduces a herbicide use amount, reduces adverse influences produced by herbicides on the ecological environment, has an important meaning for comprehensive control of herbicide resistance of weed, and has large economic and social benefits.
Description
technical field [0001] The invention relates to a paddy field herbicide composition, which uses penoxsulam and tetramen as active ingredients and is used for controlling annual weeds in paddy fields. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs are mixed, but also the emergence of weeds is uneven, and the seeds, young and old weeds are staggered, so the herbicide species alone When used, all will show some defects and limitations. [0003] Penoxsulam is a broad-spectrum herbicide for post-emergence paddy fields. It can effectively control barnyard grass, stephae and annual Cyperaceae weeds, and is effective against many broad-leaved weeds with a long-lasting eff...
