Embodiment 1

[0020] Embodiment 1 is a dosage form preparation example, and embodiment 2 is a biological embodiment,

[0021] Example 1:

[0022] a: cream

[0023] Mix 20% active component A and 20% active component B with 10% alkylphenol polyoxyethylene ether as emulsifier and 60% toluene as solvent in the reaction kettle.

[0024] b wettable powder:

[0025] With 20 parts of weight of effective composition and 2 parts of weight of sodium dodecylbenzenesulfonate as wetting agent, 10 parts of weight of granular white carbon black as adsorbent, 5 parts of weight of sodium dodecylbenzene sulfonate as dispersant Sodium lignosulfonate and 63 parts by weight of kaolin are ultrafinely pulverized in a jet mill.

[0026] c powder:

[0027] It is prepared by mixing 10 parts by weight of the effective composition and 90 parts by weight of talcum powder as an inert substance, and pulverizing them uniformly in a high-speed pulverizer.

[0028] d Granules:

[0029] It is prepared from 20 parts by ...

Embodiment 2

[0032] Example 2, the control effect of clodinafop-propargyl and bensulfuron-methyl on weeds in wheat fields

[0033] Location: Jiangsu, Xinyi

[0034] Application period: Weed 2-3 leaf stage investigation: 30 days after application: 2008

[0035]

[0036] Conclusion: The actual control effect of clodinafop-propargyl and bensulfuron-methyl is higher than the expected theoretical control effect of the mixed use, and the herbicidal spectrum can be expanded at the same time. .

Abstract

The invention provides a weedicide composition containing clodinafop-propargyl, belonging to the improved weedicide compositions. The invention also provides a preparation method and application of the composition. The composition is a mixture of a compound (A) and bensulfuron-methyl and can effectively prevent and kill off the annual grass weeds and broadleaf weeds in the cornfields. The controleffect of the composition is obviously better than that of the single compound (A) or compound (B), thus substantially reducing the application dosage of various active substances.

Description

Technical field: [0001] The present invention relates to herbicidal compositions having improved properties. Background technique: [0002] The common name of compound (A) is clodinafop-propargyl, and its chemical name is 2-propynyl-(R)-2-4[4-(5-chloro-3-fluoro-2-pyridyloxy)phenoxy] Propionate is a wheat field herbicide. The herbicide can effectively control sagegrass, wild oats, false oats, brachiaria, crabgrass, barnyardgrass, cricket grass, multiflora ryegrass, quinoa, common bluegrass, golden foxtail, and green foxtail in wheat fields , stone grass, and false sorghum. Bensulfuron-methyl is a paddy field herbicide, which can effectively control annual broad-leaved weeds, but the mixed use of clodinafop-propargyl and bensulfuron-methyl in wheat fields has not been reported yet. Therefore, the mixed effect of clodinafop-propargyl and bensulfuron-methyl is unpredictable. Invention content: [0003] The herbicidal composition provided by the present invention is charact...
