Problems solved by technology

[0003] The purpose of the present invention is to solve the technical problem that the existing flusulfuron-methyl has a poor control effect on grass weeds. In order to solve this problem, we have designed a cornfield herbicide compounded with flusulfuron-methyl, which has high safety and not only It can control weeds such as Abutilon, Amaranthus, Chenopodium, Chickweed and Polygonum that can be controlled when triflouron-methyl is used alone. The control effect of weeds, especially the synergistic control effect on gramineous weeds is very obvious. It broadens the herbicidal spectrum, improves the safety of corn, reduces the amount of pesticides, saves the cost of control, and reduces the pollution to the environment.

Embodiment Construction

[0016] The corn field herbicide compounded with triflouron-methyl, the key is: the components in the herbicide include by weight percentage: 5-80% of active ingredients, 5-15% of adjuvants, 5-80% of fillers, wherein the first The first active ingredient is flusulfuron, and the second active ingredient is atrazine, terbuthylazine / nicotinsulfuron, foramsulfuron, rimsulfuron / clofluroxyacetic acid, sodium dimethyltetrachloride, sulfonyl Any one of ketone, tembotrione, and fenflumezone, the weight ratio of the first active ingredient to the second active ingredient is (1:20) to (2:1).

[0017] The dosage form of the herbicide is a wettable powder, or a suspension, or a water-dispersible granule.

[0018] In the wettable powder, the auxiliary agent includes 1-6% of wetting agent and 1-6% of dispersant.

[0019] In the suspending agent, auxiliary agents include 1-6% of wetting agent, 1-6% of dispersant, 1-3% of thickener, 1-3% of preservative and 1-5% of antifreeze.

[0020] In the...

Abstract

The invention relates to a prosulfuron compounded corn field herbicide. A technical scheme adopted in the invention is characterized in that the herbicide comprises 5-80wt% of an effective component, 5-15wt% of an assistant and 5-80wt% of a filler, wherein the effective component comprises a first effective component and a second effective component, the first effective component is prosulfuron, the second effective component is anyone of atrazine, terbuthylazine / nicosulfuron, foramsulfuron, rimsulfuron / fluroxypyr, MCPA / sulcotrione, tembotrione and topramezone, and the weight ratio of the first effective component to the second effective component is (1:20)-(2:1). The prosulfuron compounded corn field herbicide has the advantages of high safety, improvement of the control effects on broad leaved weeds, grassy weeds and Cyperaceae weeds, obvious synergistic control effects on especially the grassy weeds, weed control spectrum widening, improvement of the safety degree to corns, drug consumption reduction, control cost saving, alleviation of the generation of the resistances of the weeds, and reduction of the pollution to the environment.

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 triflouron-methyl. 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. Flusulfuron-methyl is a herbicide for corn fields, wh...
