Composite weed killer special for sugarcane field

Abstract

The invention discloses a composite weed killer special for a sugarcane field, taking agroxone, diuron and ametryn as main active components, and manufactured by fully mixing following materials in a mixer according to mass percent: 10-20% of agroxone, 5-15% of diuron, 40-60% of ametryn, 1-5% of wetting agent, 1-5% of dispersant and the balance of filler. According to sugarcane weed occurrence regularity, combined with the pesticide mixing principle, the composite weed killer has wide herbicide controlling spectrum, high effect, fewer dosing times, low use cost and safety to sugarcanes; and the composite weed killer has more than 90% of annual single-dicot weed prevention effect, plays a role in soil sealing after being applied, inhibits germination of later weeds, is safe for the sugarcanes and can effectively ensure health growth of the sugarcanes.

Description

technical field [0001] The invention belongs to the pesticide formulation containing organic compounds, in particular to the pesticide containing organic compounds for controlling sugarcane annual monocot and dicotyledonous weeds. Background technique [0002] Weeds in sugarcane fields are one of the main factors affecting the high quality and high yield of sugarcane. There are many kinds of weeds in sugarcane fields, among which the gramineous weeds are the most harmful, followed by the broad-leaved weeds, and the sedge weeds are less harmful. Weeds in the field not only compete with sugarcane for water, fertilizer, light, and space, affecting the normal growth of sugarcane, but also become intermediate hosts and mediators of sugarcane diseases, insects, and rodents, inducing and aggravating sugarcane diseases, insects, and rodents. Harm, thereby reducing the yield and quality of sugarcane. [0003] Currently, atrazine, acetochlor, or a combination of the two herbicides a...

Problems solved by technology

Weeds in the field not only compete with sugarcane for water, fertilizer, light, and space, affecting the normal growth of sugarcane, but also become intermediate hosts and mediators of sugarcane diseases, insects, and rodents, inducing and aggravating sugarcane diseases, insects, and rodents. Harm, thereby reducing the yield and quality of sugarcane

[0003] Currently, atrazine, acetochlor, or a combination of the two herbicides are the most common herbicides in sugarcane fields. Atrazine has a long duration of action and is prone to phytotoxicity to crops that are sensitive to subsequent stubble. In addition, atrazine is easily washed by rainwater to make the soil weaker. Deep, seriously polluted water sources

Acetochlor is more effective against annual grass weeds, but less effective against broadleaf weeds and ineffective against perennial weeds

Glyphosate, paraquat, etc. can effectively control some malignant weeds in sugarcane fields, such as Bermudagrass, Imperatae, Cyperus cyperi, etc., but they are easy to cause phytotoxicity.

In addition, long-term single use of one herbicide can easily change the grass phase, control sensitive weeds, and develop resistant weeds with high drug resistance
