Abstract

The invention relates to a herbicide composition which comprises the following active components in parts by weight: 0.1 to 95 parts of dithiopyr and 0.1 to 95 parts of metamifop. The invention also relates to application of the herbicide composition in prevention and treatment of annual and perennial broadleaf weed and grassy weed in rice fields. Compared with a singler medicament, the herbicidecomposition obviously enhances a weeding effect, displays excellent synergism, reduces the utilization quantity of the medicament, reduces the medicament cost for farmers as well as an influence on the environment, enlarges a weeding spectrum, and also effectively prolongs the generation and the development of the resistance to the single medicament.

Description

technical field [0001] The invention relates to the field of agricultural herbicides, in particular to a herbicide composition containing two active ingredients of dithiopyr and fenpyramid and an application thereof. Background technique [0002] Dithiopyr is a pyridinecarboxylic acid pre-emergent herbicide, its herbicidal activity is not affected by changes in environmental factors (temperature, soil type and moisture), it is safe for rice, and its effective period can reach 80 days. [0003] Metamifop is an aryloxyphenoxy ester (AOPP) herbicide, which can inhibit ACC enzyme and promote plant fatty acid synthesis. As an acetyl coenzyme A carboxylase (ACCase) inhibitor, it can control most annual grass weeds very well. Unlike most AOPP herbicides, fenpyramid is safe and effective for rice Control and control the main weeds in paddy fields, such as barnyardgrass, stephenia, crabgrass and goosegrass, and are mainly used for weeding in transplanted and direct seeded paddy fiel...
