Abstract

The invention discloses a nicosulfuron-containing herbicidal composition and application thereof. The herbicidal composition is prepared from the following components: nicosulfuron, amicarbazone, and dimethyltetrachloroisooctyl ester as well as a dispersant, an emulsifier, a wetting agent, a thickening agent, an antifreeze, and a dispersion medium, wherein the dosage form belongs to a dispersed oil suspension agent. Through the combination of the three active ingredients, the herbicidal composition has an obvious synergistic effect, the use amount of pesticides is reduced, the cost and environmental pollution are reduced, the drug resistance of corn field weeds can be delayed by the application of the composition, and the control spectrum is expanded.

Description

Technical field

[0001] The invention relates to the technical field of pesticides, in particular to a herbicidal composition containing nicosulfuron and its application. Background technique

[0002] Nicosulfuron can control annual and perennial gramineous weeds and some broad-leaved weeds. Tests have shown that the weeds that are highly sensitive to medicines include turfgrass, setaria, wild oats, and amaranth; the weeds with moderate sensitivity include Polygonum benthamiana, Humulus vulgaris, Portulaca oleracea, Cocklebur, Cocklebur, and Abutilon Hemp and sedge; the less sensitive weeds are mainly Chenopodium, Solanum, Dactylis, Kochia and Mustela.

[0003] Amcarbazone is a triazolinone herbicide. It is highly effective on broadleaf weeds such as Chenopodiaceae, Amaranthaceae, and Leucanthemum. Sensitive weeds absorb this drug and destroy it by inhibiting p-hydroxyphenylpyruvate dioxidase. The formation of chlorophyll causes the chlorosis and wilting of the affected weeds. [0...

Examples

Embodiment 1
