Embodiment 1

[0042] Formulation Example 1 (20+5+1.5)

[0043] Weigh 20% terbuthylazine, 5% metazazone sulfone, 0.5% fenpyrazone, 1% clofenacyl, 4% alkyl sodium sulfate, 5% alkyl naphthalene sodium sulfonate, 1% bentonite, 6% Propylene glycol, 0.5% isothiazolinone, 0.5% butanol, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 26.5% terbutyzine-metrazazone-sulfone-oxazone suspension concentrate.

Embodiment 2

[0044] Formulation Example 2 (20+5+3)

[0045] Weigh 20% terbuthylazine, 5% metazazol sulfone, 3% tembotrione, 4% clofenacyl, 4% triphenylethylphenol polyoxypropylene polyoxyethylene block polymer, 3% alkyl polyoxyethylene Sodium oxyethylene ether sulfonate, 3% magnesium aluminum silicate, 0.5% carboxyethyl cellulose, 5% polyethylene glycol, 0.5% sodium benzoate, 0.5% silicone oil, and deionized water added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 28% terbutyzine-metraclofenazole-sulfone suspension concentrate.

Embodiment 3

[0046]Formulation Example 3 (20+5+1.5)

[0047] Weigh 20% terbutyzine, 5% pyrazazone sulfone, 0.5% fenfentrazone, 2% clofenacyl, 2% sodium lignosulfonate, 5% Nongru 1601#, 3% Span-60# , 1% sodium alkylsulfonate, 0.5% polyvinyl alcohol, 5% propylene glycol, methyl oleate added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 26.5% terbutyzine-metrazazone-sulfenoxazone dispersible oil suspension concentrate.

Abstract

The invention belongs to the field of pesticide compounding, and particularly relates to a ternary weeding composition containing terbuthylazine and application thereof. The ternary weeding composition comprises weeding active ingredients A, B and C. The active ingredient A is terbuthylazine, the active ingredient B is pyroxasulfone, and the active ingredient C is selected from one of topramezoneand tembotrione. The composition can be prepared into a plurality of dosage forms allowable in pesticides in practical application, and the good dosage forms comprise a suspending agent and a dispersible oil suspending agent. The composition can effectively prevent and kill various gramineous and broadleaf weeds in corn fields, and has the characteristics of expanding the weed control spectrum, reducing the use amount, reducing the cost, being safe to crops, generating a synergistic effect, solving resistant weeds and the like.

Description

technical field [0001] The invention relates to a herbicidal composition, which is composed of the first active ingredient terbuthylazine, the second active ingredient metazazone sulfone, the third active ingredient oxentrazone or one of tembotrione and an auxiliary agent, belonging to compound Dispensing pesticide technical field. Background technique [0002] Terbuthylazine, English name: Terbutylazine, Terbuthylazine is a selective systemic conduction herbicide, it can be absorbed from the root before budding, or can penetrate into the plant from the stem and leaf, and transported to the green leaves to inhibit photosynthesis, generally for Freshly sprouted weeds do better. It is suitable for corn, sorghum, soybean, pome fruit trees, citrus, grapes and other crops. It can control annual broad-leaved and gramineous weeds. The effect on broad-leaved weeds is better than that of grasses, but the effect on perennial weeds is relatively weak. Difference. [0003] Pyrazone s...
