Embodiment 1

[0027] Embodiment 1: the control effect test of herbicidal composition of the present invention to weeds

[0028] The test was carried out in a wheat field in Xinxiang, Henan Province. The herbicidal composition was a water-dispersible granule formulated with 93% methylsulfuron-methyl technical and 96% acetoxyflufen technical as active ingredients, and adding appropriate amount of adjuvants. . The experimental treatments and application rates are shown in Table 1.

Embodiment 2

[0036] Embodiment 2: 20% methanedisulfone ethyl carboxy wettable powder

[0037] With 93% mesosulfuron-methyl technical and 96% aciflufen-methyl technical raw materials as active ingredients, take 60 kg of medisulfuron-methyl technical, 151 kg of disulfuron-ethyl technical, 60 kg of auxiliary agents, and 729 kg of fillers After jet milling and mixing processing, 1000kg of 20% wettable powder was obtained.

[0038] Comparing the herbicide prepared in this example with the herbicide made from a single active ingredient of mesosulfuron-methyl or aciflufen, the amount of each active ingredient in the herbicide is calculated as a standard. Under the premise that the dosage of the active ingredients is less than that of each single agent, its control effect is higher than that of a single agent, and there is no cross resistance, and it can effectively control grass weeds and broad-leaved weeds at the same time.

Embodiment 3

[0039] Embodiment 3: 30% methanedisulfone ethyl carboxy wettable powder

[0040] With 93% mesosulfuron-methyl technical and 96% aciflufen-ethyl technical raw materials as the active ingredient raw materials, take 90 kg of medisulfuron-methyl technical, 225 kg of disulfuron-ethyl technical, 80 kg of auxiliary agents, and 666 kg of fillers After jet milling and mixing processing, 1000 kg of 30% wettable powder was obtained.

[0041] Comparing the herbicide prepared in this example with the herbicide made from a single active ingredient of mesosulfuron-methyl or aciflufen, the amount of each active ingredient in the herbicide is calculated as a standard. Under the premise that the dosage of the active ingredients is less than that of each single agent, its control effect is higher than that of a single agent, and there is no cross resistance, and it can effectively control grass weeds and broad-leaved weeds at the same time.

Abstract

The invention relates to the field of pesticide preparations, and discloses an herbicide composition. The herbicide composition is composed of mesosulfuron-methyl and fluoroglycofen-ethyl. The invention further provides an herbicide with active ingredients thereof composed of the herbicide composition of the invention. The herbicide composition is composed of mesosulfuron-methyl and fluoroglycofen-ethyl, widens weed control spectrum, is capable of controlling and eliminating wheat gramineous weed and broadleaf weed simultaneously, and has obvious synergistic effect, thus, the control effect is enhanced, the dosage of effective ingredients is reduced and the application cost is lowered.

Description

technical field [0001] The invention relates to the field of pesticide formulations, in particular to a herbicidal composition. Background technique [0002] Wheat is a gramineous plant widely planted all over the world. It originated in the Middle East and is one of the most important food crops in northern my country. It is rich in starch, protein, fat, minerals, calcium, iron, thiamine, and riboflavin. Niacin, niacin and vitamin A are the food crops with the second largest output in the world. my country's perennial planting area is more than 30 million hectares, second only to rice planting area, mainly concentrated in the Huanghuaihai Plain and the Yangtze River Basin. [0003] There are many weeds in wheat fields, and weeds have occurred in varying degrees in most wheat fields in my country. Due to the variety of weeds in wheat fields, wide distribution, fast growth, high density, rapid reproduction, and strong resistance to stress, they not only compete with wheat for...
