Tembotrions compound cornfield herbicide

Abstract

The invention discloses a tembotrions compound cornfield herbicide. According to the adopted technical scheme, the herbicide comprises the following components in percentage by weight: 5-80 percent of effective components, 5-15 percent of auxiliaries and 5-80 percent of filler, wherein a first effective component is tembotrions, and a second effective component is any one of atrazine, terbuthylazine / nicosulfuron, foramsulfuron, rimsulfuron / fluroxypyr, MCPA-Na / mesotrione, sulcotrione and topramezone; the weight ratio of the first effective component to the second effective component is (1:8)-(8:1). The technical effect is that multiple grassy weeds, broadleaf weeds and cyperaceae weeds which can be prevented by the independent tembotrions can be also prevented by the tembotrions compound cornfield herbicide; furthermore, a prevention effect for part of grassy weeds and part of broadleaf weeds is improved, the herbicide controlling spectrum is expanded, the safety to the corns is improved, the drug using amount is reduced, the prevention and treatment cost is reduced, and the pollution to the environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a herbicide, in particular to a corn field herbicide compounded with tembotrione. Background technique [0002] Corn is not only an important food crop in my country, but also an important feed crop and industrial raw material. With the development of industries such as animal husbandry, food processing, wine making and biodiesel, the market demand for corn continues to increase. Weeds in cornfields are common and there are many kinds. When the seedling corn is harmed by weeds, the plants will be short and the stalks will be thin and the leaves will be yellow, which will lead to poor growth of corn in the middle and later stages and a serious reduction in production. Therefore, chemical control of weeds in cornfields is widely used It is carried out in two critical periods, pre-emergence and early rise after emergence. Tetratrione is mainly used to prevent and control various gr...

Problems solved by technology

[0003] The purpose of the present invention is to solve the technical problem that existing cornfield herbicides have poor control effects on some grass weeds and broad-leaved weeds. In order to solve this problem, we have designed a cornfield herbicide compounded with tembotrione It can not only control a variety of grass weeds, broad-leaved weeds, and sedge weeds that can be controlled by tembotrione alone, but also has a synergistic effect on the control of some grass weeds and broad-leaved weeds Very significant, it broadens the herbicidal spectrum, improves the safety of corn, reduces the dosage of pesticides, and saves the cost of control
