Problems solved by technology

[0002] At present, there are many types of herbicides in wheat fields, but their functions are all single. Some can control broad-leaved weeds, and some can control grass weeds, but they cannot do both. It brings a certain degree of difficulty, affects the growth of wheat, and increases the amount of labor
[0003] Biflurazole has a wide herbicidal spectrum, and can control most of the broad-leaved weeds such as pig weed, wheatgrass, chickweed, broken rice shepherd, shepherd's purse, wild rape, etc., and

Embodiment 1

[0012] Embodiment 1 dry suspending agent

[0013] Active ingredient 10%-85%, wetting agent 0.1%-10%, disintegrant 0.1%-20%, dispersant and binder 5%-30%, particle size, suspending agent, dispersing agent, stabilizer and other properties Meet the requirements of national standards.

[0014] Take the original drug clodinafop-propargyl 300, difluramid 150, wetting agent 50, disintegrant 50, dispersant and binder 50, carrier 400kg, and obtain 1000kg of 40% dry suspension.

Embodiment 2

[0016] The 40% dry suspension concentrate obtained in Example 1 and the commercially available 15% clodinafop-propargyl and 58% diflumezamide were sprayed in respective wheat experimental fields respectively, and the herbicidal effects were compared as follows:

[0017] Drug type

[0018] It can be seen from the above examples that the comprehensive herbicide effect of the compound herbicide for wheat fields of the present invention is significantly enhanced, and it is worthy of vigorous promotion.

Abstract

The present invention relates to a compounded herbicide for wheat fields. The compounded herbicide contains 1 part to 99 parts of clodinafop-propargyl and 1 part to 99 parts of florasulam+flumetsulam, and also contains an optional carrier, a surfactant, a dispersant, and agricultural adjuvants. The compounded herbicide for wheat fields solves the problem of single effect in existing herbicides for wheat fields, and has both soil treatment and stem and leaf treatment effects. The compounded herbicide can control both grass weeds in wheat fields and broadleaf weeds and sedges; and is safe to wheat has no impact to after-reap crops; so the herbicidal effect is improved, crop injury is reduced, the occurrence of herbicide resistance of weeds and community succession are delayed, the dosage and environmental pollution are decreased, and at the same time, labor and money are save, thereby reducing the burden on farmers.

Description

technical field [0001] The invention relates to a herbicidal pesticide composition, in particular to a compound herbicide for wheat fields. Background technique [0002] At present, there are many types of herbicides in wheat fields, but their functions are all single. Some can control broad-leaved weeds, and some can control grass weeds, but they cannot do both. It brings certain difficulty, affects the growth of wheat, and increases the amount of labor. [0003] Biflurazole has a wide herbicidal spectrum, and can control most of the broad-leaved weeds such as pig weed, wheatgrass, chickweed, broken rice shepherd, shepherd's purse, wild rape, etc., and has a good inhibitory effect on lacquer , the efficacy of the drug is stable when applied at low temperature, and the stable efficacy can be guaranteed even when applied at a temperature of 2°C, but its control effect on gramineous weeds is relatively weak. [0004] Clodinafop-propargyl is quickly degraded into free acid ph...
