[0016] Patent CN201510056372.0 is a sugarcane field herbicide used for low-volume spraying. It discloses that ametryn can be compounded with chlorpyrazosulfuron-methyl and oxaflumezone respectively for sugarcane field weeding, but there is still Some weeds cannot be controlled. The combination of ametryn and chlorpyrazosulfuron can effectively control broad-leaved and sedge weeds, but the control effect on some gramineous weeds is poor. The combination can effectively control gramineous and broad-leaved weeds, but it is ineffective against sedge weeds, and the patent does not disclos

Abstract
The invention relates to a herbicide composition, in particular to a cornfield herbicide composition taking topramezone, halosulfuron-methyl and ametryn or simazine selected from a triazine herbicide as active ingredients, the weight ratio of the effective components of the topramezone to the halosulfuron-methyl to the triazine herbicide in the composition is 0.375-6 to 0.5-8 to 30-480, and the weight percentage of the effective components in the composition ranges from 10 percent to 80 percent. The compound herbicide can be prepared into conventional dosage forms such as wettable powder, water dispersible granules and suspending agents, the herbicide composition can prevent and kill off various weeds in the cornfield simultaneously, the control effect to the cornfield weeds is obviously improved, the dosage of the effective components is less, the usage cost is low, safety to corn and afterreap crops is achieved, and the herbicide composition is an ideal herbicide.
Description
【Technical field】 [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicide composition containing fenflumezone, which is used for controlling weeds in cornfields. 【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 animal husbandry, food processing industry, wine making industry and biodiesel industry, the market demand for corn continues to increase. Weeds in cornfields are common and of various types. Common weeds in cornfields in my country include crabgrass, goosegrass, barnyardgrass, foxtail, amaranth, purslane, quinoa, amaranth, velvetleaf, Cyperus cyperi, etc. When maize at the seedling stage is harmed by weeds, the plants will be short and the stems will be thin and the leaves will be yellow, which will lead to poor growth of maize in the middle and late stages and severe production reduction.
