Problems solved by technology

[0004] Although both cyclotrione and flunmetrione can control weeds in paddy fields, due to the occurrence of drug resistance during use, and the scope of resistance has expanded year by year, the control effect has decreased year by year, which has led to the single component of its single component on rice. The comprehensive control effect of field weeds is low, and the purpose of weeding cannot be achieved

Embodiment 1、19

[0028] Embodiment 1, 19% suspending agent

[0029]

[0030]

[0031] Preparation method: Mix the components according to the ratio and feed, stir and mix evenly; then put the mixture into the colloid mill for initial sanding, turn on the air source to control the temperature, and enter the sand mill for 2.5-3.0 hours, and then Add high-speed homogeneous shear and stir for 10 minutes to obtain a homogeneous liquid.

Embodiment 2、26

[0032] Embodiment 2, 26.5% dispersible oil suspension concentrate

[0033]

[0034] Preparation method: Feed the above raw materials according to the proportion, stir for half an hour and mix evenly; open the valve, the mixture enters the colloid mill for initial sanding, and then enters the sand mill for sanding, and turns on the circulating water to control the temperature. According to the product characteristics, select different temperatures, sand Grind for 2.5 hours; after sand milling, stir for half an hour under high-shear homogeneous mixing to obtain a uniform liquid.

Embodiment 3、325

[0035] Embodiment 3, 32.5% microemulsion:

[0036]

[0037] Preparation method: Feed Cyclotrione, Fluorone Sulfame, emulsifier, and solvent according to the ratio, stir to dissolve and mix evenly to form an organic phase. During stirring, the temperature of the heating equipment is controlled at about 50°C, and mix and stir until the original drug is completely dissolved. , in a transparent state; then mix water and antifreeze according to the ratio to form a water phase, stir the organic phase and water phase for 30-60 minutes to mix evenly, analyze and test, carry out quality inspection of semi-finished products, mix for half an hour, settle and filter at room temperature , remove impurities and flocs, and pack after passing the inspection.

Abstract

The invention discloses a weeding composition containing tralkoxydim and triafamone, the effective components of the weeding composition are tralkoxydim and triafamone, and the mass ratio of tralkoxydim to triafamone is 4-20:15-30. The weeding composition disclosed by the invention has a synergistic effect, is mainly used for gramineous weeds in paddy fields, and has a relatively good inhibition effect on gramineous weeds, broadleaf weeds and nutgrass flatsedge, such as cymbidium sinense, Digitaria sanguinalis, moleplant seeds, green bristlegrass, Rottboellia cochinchinensis, Syzygium aromaticum, arrowhead,Eclipta prostrata, pondweed,Bidens tripartita, annualnutgrass flatsedge, Juncellus serotinus, etc. and is safe to paddy rice. The two herbicides are compounded to expand the herbicide controlling spectrum, so that the weeding composition has obvious synergistic effects and reduces the use dosage. The weeding composition has high safety, reduces the pesticide use frequency and reducethe pesticide application cost, and can also play a role in controlling weed population change, reducing weed drug resistance, maintaining agricultural ecological balance and protecting the environment, so that the compounding of the two herbicides 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 cycloclozone and flucarbazone. Background technique [0002] Cyclotrione is an ACCase inhibitor. After foliar application, it is quickly absorbed and transferred by the plant, and transferred to the growth point in the phloem, inhibiting the growth of new shoots. The weeds first lose their chlorosis, then change color and die, and generally complete within 2-3 weeks. dead. It is mainly used to control gramineous weeds in rice fields such as barnyardgrass, blue horsegrass, crabgrass, daughter of a daughter, foxtail, and cyperus, and is safe for direct-seeding rice and transplanting rice; but for broad-leaved and Cyperaceae weeds The control effect of grass is not ideal. [0003] Flucarbazone, the English common name triafamone, development code AE1887196, BSC-BX60309, CAS accession number 874195-61-6, flucarbazone is a...
