Embodiment 110

[0182] Embodiment 1 10% compound A emulsion in water

[0183] Add 10% compound A, 5% T-20, 3% EL-80, 1% 500#, 4% ethylene glycol, 15% caprylamide, 30% methyl oleate into the mixing tank, stir and mix to dissolve To form a uniform oil phase, under high-speed stirring, add the remaining amount of water (to make up to 100%) into the oil phase to obtain a 10% compound A water emulsion with good dispersibility.

[0184] Seal the obtained 10% water emulsion sample of Example 1 and the original drug with an ampoule bottle, and store it in a thermostat at 54±2°C for 14 days. The liquid chromatographic analysis method is used to analyze and detect the content changes of the active ingredients before and after storage. Its decomposition rate is less than 5%. The analysis results are shown in Table 1

[0185] Table 1

[0186]

[0187] The results show that in the preparation system, methyl oleate is added, so that the decomposition rate of Example 1 is significantly smaller than t...

Embodiment 2

[0188] Embodiment 2 10% compound A emulsion in water

[0189] Add 10% compound A, 2% 600#, 4% 1601, 2% 500#, 4% ethylene glycol, 20% caprylamide into the mixing kettle, stir and mix to dissolve into a uniform oil phase, under high-speed stirring, A 10% compound A water emulsion with good dispersibility can be obtained by adding the remaining amount of water (to make up to 100%) into the oil phase.

[0190] The 10% emulsion in water sample obtained in Example 2 and the original drug were sealed in ampoules, and stored in a thermostat at 54 ± 2°C for 14 days. The liquid chromatographic analysis method is used to analyze and detect the content changes of the active ingredients before and after storage. Its decomposition rate is greater than 5%. The analysis results are shown in Table 2

[0191] Table 2

[0192]

[0193] The result shows that the decomposition rate of embodiment 2 is greater than the original drug decomposition rate.

Embodiment 3

[0194] Example 3 10% Compound A Dispersible Oil Suspension Concentrate

[0195] Add 10% compound A, 5% O-3, 10% S-80, 5% T-80, 1% organic bentonite, and the remaining amount of methyl oleate (to make up to 100%) into the mixing kettle, and use high shear Stir and mix with a cutting machine, and then sand mill with a sand mill to obtain a 10% compound A dispersible oil suspension concentrate with good dispersibility.

[0196] Seal the obtained 10% dispersible oil suspension concentrate sample of Example 3 with the original medicine ampoule, and store it in a thermostat at 54±2° C. for 14 days. The liquid chromatographic analysis method is used to analyze and detect the content changes of the active ingredients before and after storage. Its decomposition rate is greater than 5%. The analysis results are shown in Table 3

[0197] table 3

[0198]

[0199] The result shows that the decomposition rate of embodiment 3 is less than the original drug decomposition rate.

Abstract

The invention belongs to the field of herbicides and in particular relates to an herbicide and application thereof. A weeding preparation comprises at least one carrier and at least one aid, the preparation has herbicide dosage forms of a water emulsion, a dispersible oil suspending agent, a dispersible oil agent, a micro emulsion, cream, a soluble liquid agent, an aqueous agent, a suspending agent, a suspension emulsion, an ultra-low capacity agent, powder, wettable powder, granules, dry water dispersible granules, a dry suspending agent, a microcapsule suspending agent, emulsion powder, effervescent granules, an effervescent tablet agent and a water dispersible tablet with the compound of the formula I as an active component. By adopting varieties of the preparation provided by the invention, weeds such as barnyard grass, green bristlegrass, sedges, water sedge, digitaria, hispid arthraxon, abutilon, zinnia elegans, amaranthus retroflexus, purslane, xanthium sibiricum, cassia tora, wild watermelon seedlings and wild soybean seedlings can be effectively controlled, a very good weeding effect can be achieved with a low dosage, and the preparation has good security for crops such ascorn, wheat and rice and can be used as a herbicide in agriculture.

Description

technical field [0001] The invention belongs to the field of herbicides, and relates to a herbicide containing isoxazoline-based uracil compounds and an application thereof. Background technique [0002] Patent WO2016095768 reports the isoxazoline-containing uracil compound A as shown in general formula I: [0003] [0004] The compound A of the general formula I has good herbicidal activity, and can effectively control barnyardgrass, foxtail, heteromorphous sedge, water sedge, crabgrass, weed grass, velvetleaf, zinnia, retroflexus, purslane, Weeds of different leaf stages such as cocklebur, black nightshade, cassia, wild watermelon seedlings, and wild soybeans can achieve good herbicidal effects at low doses. [0005] Compound A should be formulated into corresponding preparations according to the different methods of use and crops, such as water emulsion, dispersible oil suspension, dispersible oil, microemulsion, emulsifiable concentrate, soluble agent, water agent, s...
