Abstract

The invention relates to a weeding composition containing active components of oxaziclomefone and penoxsulam in a weight ratio of 1:20-20:1. The weeding composition can be prepared into a suspension agent, an oil suspension agent, a wettable powder and a water dispersion granule according to the application requirements, and can be applied to control of annual weeds in rice fields. The composition has control effect on weeds in rice fields better than that of each single agent, and can reduce the dosage, delay drug resistance of weeds and mitigate environmental pollution.

Description

technical field [0001] The invention relates to a pesticide herbicide composition and its application field, in particular to a herbicide composition with oxaziclozone and penoxsulam as active ingredients, which is applied to control 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 use of some herbicide varieties alone, many weeds have developed resistance. At the same time, due to the complex grass phase when weeds occur, grass weeds, broad-leaved weeds and sedge weeds and other weeds are mixed, the use of a single herbicide cannot effectively solve the weeds in the farmland, and they will all show certain aspects defects and limitations. Mixing different types of herbicides has many advantages, such as broad herbicidal spectrum, improved control effect, delaying weed resistance, saving time and labor. [0003] Oxaziclomefone, also known as Qu...
