Embodiment 1

[0246] Embodiment 1 (34.5% wettable powder)

[0247] Bensulfuron-methyl 4.5%, 2-(quinolin-8-yl)-carbonyl-cyclohexane-1,3-dione compound or its tautomer 30%, sodium dodecylbenzenesulfonate 2.0%, sodium lignosulfonate 10%, diatomaceous earth to make up to 100%. In this example, the 2-(quinolin-8-yl)-carbonyl-cyclohexane-1,3-dione compound or its tautomer is specifically the compound A1 given in the specification.

Embodiment 2

[0248] Embodiment 2 (37.5% wettable powder)

[0249] Clopyrazosulfuron 7.5%, 2-(quinolin-8-yl)-carbonyl-cyclohexane-1,3-dione compound or its tautomer 30%, sodium lauryl sulfate 1.5 %, sodium lignosulfonate 10%, kaolin to make up to 100%. In this example, the 2-(quinolin-8-yl)-carbonyl-cyclohexane-1,3-dione compound or its tautomer is specifically the compound A2 given in the specification.

Embodiment 3

[0250] Embodiment 3 (25.5% wettable powder)

[0251] Pyrazosulfuron-methyl 3%, 2-(quinolin-8-yl)-carbonyl-cyclohexane-1,3-dione compound or its tautomer (A3) 22.5%, alkamido taurine Salt 6%, alkylnaphthalene formaldehyde condensate 5%, sodium dodecylbenzene sulfonate 5%, kaolin to make up to 100%. In this example, the 2-(quinolin-8-yl)-carbonyl-cyclohexane-1,3-dione compound or its tautomer is specifically the compound A3 given in the specification.

Abstract

The invention provides an herbicide composition which contains a sulfonylurea herbicidal compound and 2-(quinoline-8-yl)-carbonyl-cyclohexane-1,3-diketone compound or a tautomer thereof according to a weight part ratio of 1:50-50:1. The composition can be prepared into emulsifiable concentrate, liquor, soluble concentrate, stock emulsions, microemulsion, wettable powder, suspension concentrate, oil suspended agent, water dispersible granules or soluble powder. The herbicide composition is used for controlling annual and perennial gramineous plants and broadleaf weeds of a paddy field.

Description

technical field [0001] The present invention relates to the field of agricultural herbicides, more specifically to a herbicidal compound containing sulfonylureas, 2-(quinolin-8-yl)-carbonyl-cyclohexane-1,3-dione compounds or their mutual Composition of variants and their use. Background technique [0002] Sulfonylurea herbicides have broad spectrum, extremely low dosage, strong selectivity and low acute and chronic toxicity. These herbicides inhibit acetolactate synthase, prevent the biosynthesis of branched-chain amino acids valine, leucine, and isoleucine, and cause plant cells to stop dividing and growing. The selectivity of crops is caused by the rapid inactivation metabolism of tolerant crops. The degradation of these herbicides in soil is through the joint action of urea bridge hydrolysis and microbial degradation, and herbicides are hydrolyzed faster in acidic conditions than in alkaline conditions. [0003] The inventor of the present application once disclosed in...
