Corn field three-element weeding composition containing amicarbazone

Abstract

The invention discloses a corn field three-element weeding composition containing amicarbazone. Effective ingredients of the corn field three-element weeding composition include nicosulfuron, mesotrione and the amicarbazone. The mass ratio of the nicosulfuron to the mesotrione to the amicarbazone is (1-15):(10-40):(1-20). The corn field three-element weeding composition has an addition or synergistic effect. Use periods include the post-emergence 3-leaf period to the post-emergence 5-leaf period of corn seedlings, the 2-leaf period to the 4-leaf period of annual weed and the period before the 6-leaf period of perennial weed. The pesticide is applied when most of the weed germinates, the weeding effect is good, and the corn field three-element weeding composition is safe for corn. The annual weed, such as barnyard grass, Setariaviridis (L.) Beauv., Eleusine indica (L.) Gaertn, abutilon, Digitaria sanguinalis and Chenopodium albumL. hich, and the perennial weed which are popular in a corn field are prevented and removed. The corn field three-element weeding composition has the beneficial effects of being high in weeding activity, wide in weeding spectrum and convenient to use, is safe for the corn and is an environment-friendly herbicide.

Description

technical field [0001] The invention belongs to the technical field of pesticides and herbicides, and in particular relates to a three-way herbicide composition for corn fields containing amfentrazone. Background technique [0002] Corn is one of the three major food crops in the world. Because of its rapid maturity, high yield, strong cold resistance and high nutritional value, it is recognized as a golden food in the world. Especially in the past century, with the development of food science and technology, and the continuous improvement of people's awareness of health and diet, more and more attention has been paid to the nutritional significance of corn. In recent years, under the propaganda and guidance of the agricultural technology department, the chemical weeding technology of cornfields has been gradually accepted by the farmers due to its time-saving, labor-saving, economical and high-efficiency advantages. Comprehensive production capacity has played a positive r...
