[0009] The first object of the present invention is to solve the problem that the binary compound of nicosulfuron, bromoxynil and florasulam can only control broad-leaved weeds under the complicated situation of corn field grass , but the control effect on gramineous weeds and initial broad-leaved weeds is not ideal. While expanding the herbicidal spectrum, reduce the dosage and reduce the cost of control

Abstract
The invention discloses a cornfield herbicide composition containing nicosulfuron. Active ingredients of the cornfield herbicide composition consist of nicosulfuron, bromoxynil octanoate and florasulam, wherein the nicosulfuron accounts for 0.5-20% of the weight of the composition, the bromoxynil octanoate accounts for 1-30% of the weight of the composition, and the florasulam accounts for 0.1-20% of the weight of the composition. The cornfield herbicide composition disclosed by the invention can be prepared into an agriculturally allowable dispersible oil suspending agent, a suspending agent, a water dispersible granules or wettable powder. The cornfield herbicide composition is reasonable in component compounding, shows a significant synergistic effect, improves the control effect on cornfield weeds, expands the control spectrum of the cornfield weeds, increases the fast-acting property, prolongs the persistence, and reduces the medication cost, and the prepared dosage forms have good corn safety. The composition disclosed by the invention has a relatively good control effect on grassy weeds and broadleaf weeds in a cornfield.
Description
technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to a herbicide composition, in particular to a cornfield herbicide composition containing nicosulfuron, which is suitable for controlling weeds in cornfields. The invention also relates to the preparation and processing technology of the herbicide composition. Background technique [0002] Corn is one of the three major food crops in the world. Weeds in cornfields are common and of various types, mainly broad-leaved weeds such as retroflexus, quinoa, bindweed, nightshade, amaranth, velvetleaf, amaranthus, horse Purslane, cocklebur, commelina, cow chickweed, etc.; Grass weeds such as barnyardgrass, crabgrass, foxtail, goosegrass, bermudagrass, stephenia, etc.; Cyperaceae weeds such as Cyperus cyperus. Weeds compete with corn for water, nutrients, light and space, especially affecting the normal growth of corn seedlings, and even causing severe yield reduction. Corn seedli...
