Problems solved by technology

It is mainly used to control gramineous weeds in rice fields such as barnyardgrass, blue horsegrass, crabgrass, daughter of a daughter, foxtail, and cyperus. It is safe for direct-seeding rice and transplanting rice; but for broad-leaf and sedge The control effect is not ideal

Embodiment 1、26

[0027] Embodiment 1, 26% emulsifiable concentrate

[0028]

[0029] Preparation method: first add solvent according to the ratio and start stirring, then mix and stir the original drug and emulsifier until the original drug is dissolved, and control the temperature of the heating equipment at about 50°C during stirring. After passing the product analysis and testing, mix again for half an hour, settle and filter at room temperature to remove impurities and flocs, and obtain a uniform liquid.

Embodiment 2、28

[0030] Embodiment 2, 28.5% dispersible oil suspension concentrate

[0031]

[0032]

[0033] Preparation method: first feed the original drug, emulsifier, and methyl oleate according to the ratio, and stir for half an hour to mix evenly. Open the valve to enter the colloid mill for sanding, and turn on the circulating water to control the temperature (choose a different temperature according to the product characteristics). After sanding for 2.5 hours, mix evenly under high-shear homogeneous stirring for half an hour to obtain a uniform liquid.

Embodiment 3、42

[0034] Embodiment 3, 42.5% suspending agent:

[0035]

[0036] Preparation method: mix the components according to the ratio and feed, stir for 30 minutes to mix evenly; put it into the colloid mill for initial sanding, turn on the air source to control the temperature, and then enter the sand mill for sanding, and then enter the high-speed homogenization after 2.5-3.0 hours of sanding Stir under mass shear for 10 minutes; a homogeneous liquid is obtained.

Abstract

The invention discloses a weeding composition containing clethodim. The effective components of the weeding composition are profoxydim and an amide herbicide, wherein the mass ratio of the profoxydimto the amide herbicide is (1-20): (20-60), and the amide herbicide is selected from one of pretilachlor and butachlor. The weeding composition disclosed by the invention has a synergistic effect, andhas a relatively good inhibition effect on gramineae, broad-leaved weeds and nutgrass flatsedge such as cymbidium sinense, crab grass, moleplant seeds, green bristlegrass, stipa glauca, Trachea atrix,cyperus difformis and monochoria vaginalis in a rice field, is safe to rice, and is an environment-friendly herbicide. The two components are compounded to expand the herbicide controlling spectrum,achieve obvious synergistic effects, reduce the use dosage, achieve high safety, reduce the pesticide use frequency and reduce the pesticide application cost, and also play a role in controlling weedpopulation change, reducing weed drug resistance, maintaining agricultural ecological balance and protecting the environment, so that the compounding of the two components is worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a herbicidal composition containing cyclazone. Background technique [0002] Cyclotrione is an ACCase inhibitor. After foliar application, it is quickly absorbed and transferred by the plant. It transfers to the growth point in the phloem and inhibits the growth of new shoots. The weeds will first lose their chlorosis, then change color and die, usually 2-3 weeks completely dead inside. It is mainly used to control gramineous weeds in rice fields such as barnyardgrass, blue horsegrass, crabgrass, daughter of a thousand golds, foxtails, and tulips. It is safe for direct-seeding rice and transplanting rice; but for broad-leaved and sedge weeds The control effect is not ideal. [0003] Amide herbicides are photosynthetic system II inhibitors, which can be used in both pre-emergence and seedling stages. They are mainly absorbed by weed sprouts and young sec...
