Problems solved by technology

[0002] The application of chemical herbicides is the most effective means of weed control in farmland, but long-term, continuous high-dose application of chemical herbicides of a single species or single mode of action is likely to cause the development of weed resistance and resistance, and the single active component The weeding range of traditional herbicides is narrow, and long-term application will aggravate environmental pollution. The development of new herbicides will also cause the above problems to repeat. At the same time, the cost of developing new herbicides continues to rise

Abstract

The invention relates to the field of herbicide, and particularly relates to special herbicide for a rice field and contains penoxsulam. The herbicide comprises the following three active components: the penoxsulam, simetryn and 2-methyl-4-chlorophenoxy acetic acid or a derivative of the 2-methyl-4-chlorophenoxy acetic acid, wherein the weight ratio of the penoxsulam to the szimetrin to the 2-methyl-4-chlorophenoxy acetic acid or to the derivative of the 2-methyl-4-chlorophenoxy acetic acid is (1-10):(1-50):(1-50). According to the herbicide disclosed by the invention, the herbicidal activity is remarkably improved, also the dosage is reduced, the weed control spectrum is wide, the control efficiency is durable, and the herbicide is environmentally friendly, low in dosage, easy to degrade, high in safety with regard to and also durable in efficacy and has high safety on after-reap crops.

Description

technical field [0001] The invention relates to the field of herbicides, in particular to a special herbicide for paddy fields containing penoxsulam. Background technique [0002] The application of chemical herbicides is the most effective means of weed control in farmland, but long-term, continuous high-dose application of chemical herbicides of a single species or single mode of action is likely to cause the development of weed resistance and resistance, and the single active component Herbicides have a narrow weeding range, and long-term application increases environmental pollution. The development of new herbicides will also cause the above problems to repeat. At the same time, the cost of developing new herbicides continues to rise. In contrast, the development of high-efficiency, low-toxicity, low-residue compound and mixed varieties has the advantages of less investment and short development cycle, and has been valued by researchers at home and abroad.
