Problems solved by technology

[0009] Herbicide compositions containing metazapyr sulfone or imazethapyr have been reported in the literature. For example, patent 201610779173.7 and patent 201610771120.0 disclose imazamox, lactofen or imazamox, respectively. It is used for weeding in soybean fields, but the former composition cannot control all gramineous weeds in soybean fields, while the latter composition has poor control effect on some broad-leaved weeds; patent 201510712580.1 discloses the suspending agent of pyroxazole and triflumezin The composition can be applied to weeding in soybean fields, wheat fields and corn fields, but the composition has poor control effect on some broad-leaved weeds in soybean fields

Embodiment 1

[0053] Formulation Example 1: 30% Metrazazole sulfone · Imazethapyr wettable powder

[0054]

[0055] After the above-mentioned components are uniformly mixed according to the formula ratio, the wettable powder of 30% metazazole sulfone imazamox wettable powder is obtained through the conventional method of preparing wettable powder, that is, pre-mixing, jet milling, and post-mixing.

Embodiment 2

[0056] Formulation example 2: 76% metazazole sulfone imazamox wettable powder

[0057]

[0058]

[0059] After the above-mentioned components are mixed uniformly according to the formula ratio, the wettable powder is prepared by the conventional method, that is, pre-mixing, jet milling, and post-mixing, to obtain a 76% metazazole sulfone-imazethapyr wettable powder.

Embodiment 3

[0060] Formulation example 3: 32% metazazole sulfone imazamox wettable powder

[0061]

[0062] After mixing the above-mentioned components uniformly according to the formula ratio, the conventional wettable powder preparation method, ie pre-mixing, jet milling, and post-mixing, was used to obtain 32% metazazole sulfone-imazethapyr wettable powder.

Abstract

The invention discloses a herbicide composition, and particularly discloses a herbicide composition taking pyroxasulfone and imazamox as the active ingredients and used for preventing and kill weeds in a soybean field. The weight ratio of the pyroxasulfone to the imazamox in the active ingredients of the composition is 7:50 to 175:2, and the weight percentage of the active ingredients in the composition is 5-85%. The compounded herbicide can be prepared into a wettable powder, a water dispersible granule, missible oil, a dispersible oil suspension agent, a suspension agent and the like. The herbicide composition can prevent and kill various weeds in the soybean filed at the same time, the preventive effect of the weeds in the soybean field is obviously improved, the use level of the effective ingredients is low, the use cost is low, and the herbicide composition is safe for the soybean and the afterreap crop, and is an ideal herbicide.

Description

【Technical field】 [0001] The invention discloses a soybean field herbicide composition, in particular a herbicide composition for controlling soybean field weeds with pyrazafen and imazethapyr as active ingredients. 【Background technique】 [0002] Soybean is an important food crop and oil crop in my country, as well as an important non-staple food raw material, with an annual planting area of ​​nearly 10 million hectares. Soybean is often harmed by various weeds from sowing to harvest. The main weed damage areas are Northeast China, Huanghuaihai Region, Yangtze River Basin and South China. Due to the influence of climate and soil quality, the types and numbers of weeds vary among regions, and the degree of damage to soybeans is also different. The main weeds in soybean fields are: annual gramineous weeds such as barnyard grass, foxtail, crabgrass, wild oats, goosegrass, etc., annual broad-leaved weeds include cocklebur, amaranth, amaranth, nightshade, quinoa, purslane , pi...
