Abstract

The invention belongs to the technical field of pesticides, and provides a mixed herbicide containing topramezone and pethoxamid and application thereof. The mixed herbicide employs topramezone and pethoxamid as the main effective compositions, and the mass ratio of topramezone to pethoxamid is 1:15-900:1. The mixed herbicide is applied to weed in corn field, and possesses substantial effect when being applied to control and remove various gramineae, cyperaceae and broadleaf weeds which have or are about to break through the earth. Compared with a single agent, under the premise of improving the pesticide effect, the mixed herbicide delays weed resistance, is wide in weeding spectrum and long in persistent period, and is safe to corn.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a mixed herbicide comprising fentrazone and methoxam and an application thereof. Background technique [0002] Corn is one of the three major food crops in my country. The level of corn production directly affects my country's food security, farmers' income and economic development. Due to the environment of corn production, there are a lot of weeds in corn fields. Weeds not only compete with corn for nutrients, water, sunlight and space, but also easily cause diseases and insect pests. The pollen or seeds of some weeds also contain toxins, which directly affect Maize growth and human health. Therefore, weeding in cornfields is one of the key steps for high yield and high harvest of corn. There are more than 40 kinds of weeds in cornfields, including grass weeds such as barnyard grass, stephenia, crabgrass, sedges such as sedge, and polygonum, cocklebur, velvetleaf, purslane, ...
