Embodiment 148

[0033] Example 1 48% quinclosinone·clofluridinate·cyhalofop-ester emulsifiable concentrate

[0034] 30% quinclomid, 3% chlorofluoropyridine, 15% cyhalofop, 5% cyclohexanone, 15% ethyl acetate, 10% styrylphenol polyoxyethylene ether, solvent naphtha S-150 Top up to 100%. The above materials are mixed in proportion, dissolved and stirred evenly, and 48% quinclomidone·halopyridinate·cyhalofop-ester EC can be prepared.

Embodiment 2

[0035] Example 2 26% quinclomidone · clofluridinate · cyhalofop-ester dispersible oil suspension concentrate

[0036] 20% quinclomidone, 1% chlorofluoropyridine, 5% cyhalofop-methyl, 6% naphthalenesulfonate formaldehyde condensate, 12% calcium dodecylbenzenesulfonate, 2.5% xanthan gum, vegetable Seed oil makes up to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare 26% quinclozone·halopyridin·cyhalofop-ester dispersible oil suspension concentrate.

Abstract

The invention discloses a weeding composition containing dichloroquinolone, florpyrauxifen and cyhalofop-butyl. Effective active components are composed of dichloroquinolone, florpyrauxifen and cyhalofop-butyl, and the weight ratio of dichloroquinolone to florpyrauxifen to cyhalofop-butyl is 30-300: 5: 5-85. The weeding composition is mainly applied in controlling weeds in rice field. In comparison with a single dosage or a binary combination, the weeding composition has the following advantages: the weeding effect is obviously raised; weeding spectrum is widened; persistent period is long; and the product is safe to rice.

Description

technical field [0001] The present invention relates to a pesticide composition and its application field, in particular to a synergistic herbicidal composition with quinclomidone, chlorfluopyridine and cyhalofop-methyl as effective active ingredients. Used in the control of weeds in paddy fields. Background technique [0002] Dichloroquinone (quintrione): chemical name is 2-(3,7-dichloroquinolin-8-yl) carbonyl-cyclohexanone-1,3-dione, CAS number is 1350901-36-8, is A new type of herbicide independently developed by my country, the mechanism of action is HPPD inhibitor. It has high biological activity on the main autumn weeds such as barnyardgrass, barnyardgrass, barnyardgrass, bald barnyardgrass, barnyardgrass, crabgrass, sedge, moshangcai, special-shaped sedge, broken rice sedge, etc. The grass has special effects, and has a certain inhibitory effect on Cormina auricularis and Amaranthus auricularia. It can be used in rice fields to control a variety of Gramineae, broad-l...
