Abstract

The invention relates to a cornfield weedicide composition as well as a preparation method and application thereof and in particular relates to a preparation method and application of a weedicide composition containing nicosulfuron and benzobicyclon. The composition is composed of two effective components including the nicosulfuron and the benzobicyclon. The cornfield weedicide composition is characterized in that the mass ratio of the nicosulfuron to the benzobicyclon is (1 to 40) to (40 to 1); in the preparation, the total mass of the effective components including the nicosulfuron and the benzobicyclon accounts for 1 percent to 80 percent of the total mass of the whole preparation. According to the composition provided by the invention, a proper amount of an auxiliary agent or carrier is added and can be prepared into missible oil, wettable powder, a suspending agent, a dispersible oil suspending agent, water dispersible granules and a dry suspending agent. The cornfield weedicide composition can be used for preventing and controlling annual and perennial grassy weed and broadleaf weed of a cornfield and has a relatively good synergistic effect. The compound pesticide has high efficiency and low toxicity, and good quick-acting performance and persistence.

Description

technical field [0001] The invention relates to a cornfield herbicide composition and its preparation method and application, in particular to the preparation method and application of the herbicide composition containing nicosulfuron and bicyclic sulcotrione. Background technique [0002] Corn is the cereal crop with the widest planting range and the largest yield in the world, ranking first among the three major grains. my country is a big country in corn production and consumption. Its sown area, total output and consumption are second only to the United States, ranking second in the world. Corn is an important food crop, high-quality feed crop and important industrial raw material. Corn has strong adaptability, wide distribution, multiple uses, great potential for increasing production, and rapid development. Corn occupies an important strategic position in my country's food security. [0003] The damage of weeds in corn field is an important factor affecting the yield...
