Embodiment 1

[0012] Example 1: 7% Nicosulfuron-fluxene oxalic acid oil suspension concentrate. Take 3.5kg of nicosulfuron, 3.5kg of fluoxalic acid, 8kg of Pluronic125, 5kg of propylene glycol, 8kg of xanthan gum, 1kg of methylated vegetable oil, and make up to 100kg of water. The oil suspension is obtained through full mixing and preparation, ball milling, adjustment and packaging.

Embodiment 2

[0013] Example 2: 8% nicosulfuron-flufenoxalic acid wettable powder, take 3.5kg nicosulfuron, 4.5kg flufenoxalic acid, 6kg dispersant NNO, 3kg wetting agent K12, and white carbon black to make up to 100kg. Wettable powder is obtained through thorough mixing, jet milling and mixing.

Embodiment 3

[0014] Example 3: 9% nicosulfuron-flufenoxalic acid water-dispersible granules, take 4kg nicosulfuron, 5kg flufenoxalic acid, 7kg D-425, 5kg EFW, 5kg ammonium sulfate, 2kg polyethylene glycol, kaolin Make up 100%, and obtain water-dispersible granules through thorough mixing, jet milling, mixing, granulation, drying and sieving.

Abstract

The invention relates to a weeding composition applied in the post-emergence period of corn, which belongs to the technical field of herbicides and aims to solve the technical problem of providing a cornfield stem leaf compound herbicide which not only can prevent and remove annual grassy weeds in cornfields, but also can prevent and remove broad leaved weeds and has no influence on corn safety and succession crops. The invention has the technical key points that the effective components thereof are nicosulfuron and flumiclorac-pentyl in the proportion by weight of 1:0.75-1.5. The herbicide of the invention has remarkable weeding effect, is obviously superior to the two single agents and has remarkable synergistic action for the broad leaved weeds. Meanwhile, the herbicide has broad weeding spectrum, can effectively prevent and remove the annual grassy weeds and the broad leaved weeds, can prevent and remove the weeds in the whole growing period of crops by being applied once, has no influence on the succession crops and is a more ideal cornfield herbicide at present.

Description

Technical field: [0001] The invention relates to a field herbicide for crops, in particular to a corn post-emergence herbicide composition. technical background: [0002] Corn is not only an important food crop in my country, but also an important feed crop. In recent years, with the development of industries such as animal husbandry, food processing, wine making and biodiesel, the market demand for corn has continued to increase. In 2009, my country's corn planting area reached 28.5 million hectares, ranking third after rice and wheat planting area, and there is still an increasing trend. Although the planting area of ​​corn is less than that of wheat, its yield exceeds that of wheat. Weeds in cornfields are common and of various types. In Huanghuaihai summer corn weeds occurred seriously, and the area of ​​weeds accounted for 82% to 96% of the planting area in this area, of which the area of ​​moderate damage was 64% to 66%. Maize seedlings are most seriously damaged b...
