Problems solved by technology

The current herbicides for controlling broad-leaved weeds are very low in safety for corn, and they are basically sprayed in a directional way when used, and with the extensive use of the above-mentioned herbicides, the problem of weed resistance is becoming more and more serious; Mixed one-time solution to grass broadleaf weeds in cornfields has become an urgent need

Abstract

The invention relates to the field of herbicides, and especially discloses a cornfield compounded herbicide composition. The cornfield compounded herbicide composition comprises a component A and a component B according to a weight ratio of 1-500:500-1, wherein the component A is 2,4-DB and its derivatives, and the component B is one or more of nicosulfuron, rimsulfuron and foramsulfuron. The cornfield compounded herbicide composition has the advantages of cooperative and synergistic effect, weed control spectrum enlargement, weeding activity improvement, solving of the disadvantage of bad control effect of single dosage forms on main weeds, long persistent period, guarantee of no weed harms in the whole growth period after one time dosing, safety to corns, effective reduction of the drug application cost of peasants, and economic benefit increase.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a cornfield herbicide composition containing 2,4-dichlorophenoxybutyric acid and derivatives thereof. Background technique [0002] Maize is one of the main food crops in the world, and its production spreads across all continents except Antarctica. In my country, corn is also the main food crop. The planting area of ​​corn in my country accounts for 1 / 6 of the planting area of ​​food crops, and the area is about 300 million mu. [0003] There are many kinds of weeds in cornfields. According to statistics, there are more than 200 kinds of weeds that can cause weed damage. Among them, there are more than 20 kinds that are the most common and most harmful. The main weeds are barnyardgrass, goosegrass, crabgrass, foxtail, spinach, amaranth, amaranth, purslane, Cyperus rotundum and so on. [0004] At present, herbicides in corn field are mainly divided into pre-emergence herbici...
