In formula, X is proxazuron-methyl when using a single dose to the fresh weight inhibition rate of target weeds；
Y is clefoxidim when using a single dose to the fresh weight inhibition rate of target weeds；
E0To the theoretical value of target weed fresh weight inhibition rate for proxazuron-methyl and when two kinds of pharmacy mix of clefoxidim；
To the measured value of target weed fresh weight inhibition rate when E is proxazuron-methyl and two kinds of pharmacy mix of clefoxidim.
If the actual control of weeds rate (E) observed in biologic test is more than to be calculated using Colby ' s method
Desired value (the E arrived0), then it represents that the effect of Herbicidal combinations is greater than the summation of each agent effectiveness, it means that composition has
Synergistic effect.
Herbicidal combinations of the invention are directed to important noxious plant (gramineae weed, broadleaf weeds, the nutgrass flatsedge of following wide spectrum
Section weeds) it is tested: rice barnyard grass (Echinochloa oryzicola), herba digitariae (Digitaria spp.) herba stellariae mediae
(Stellaria media), Amaranthus retroflexus (Amaranthus retroflexus), volume stem smartweed (Fallopia (ex
Polygonum) Convolvulus), piemarker (Abuthilon theophrasti), anti-sulfonylureas angustifolia arrowhead herb
(Sagittariatrifolia), rhizoma alismatis (Oriental Waterplantain Rhizome), anti-sulfonylureas Monochoria vaginalis
(Herb of Pygmy Arrowhead), Monochoria korsakowii (Monochoria korsakowii), Procumbent Falsepimpernel (Lindernia
Procumbens), black nightshade (Solanum nigrum L.), firefly Lin (Scirpus juncoides Roxb), anti-sulfonylureas it is different
Type nutgrass flatsedge (Cyperus difformis L.), Chenopodiaceae (Chenopodium alum L.), wild avena sativa (Avena fatua L.),
Clearvers (Galium aparine L. var. tenerum Gren.et (Godr.) Rebb.).
To the activity of barnyard grass:
To the activity of semen euphorbiae:
Fight the activity of the angustifolia arrowhead herb of sulfonylureas:
Fight the activity of the difformed galingale herb of sulfonylureas:
Test result is shown: proxazuron-methyl and clefoxidim in the range of 50:1-1:50, prevent and kill off gramineae weed,
Broadleaf weeds, sedge weed show apparent synergistic effect, effectively ensure to the anti-sulfonylurea herbicide in current part
Weeds prevention and treatment, improve the effect of antagonism weed control
In summary, Herbicidal combinations of the invention, activity when preventive effect is administered alone better than each component, pharmacodynamic test are tested
Demonstrate,proving a combination thereof has synergistic effect, expands control of weeds spectrum, the crop fields grass family, broadleaf weeds and Cyperaceae are prevented and kill off in primary application
Weeds reduce spraying times, reduce control cost, slow down the generation of Weed Resistance, good to crop safety, meet pesticidal preparations
Security requirement.Weeding is closed before can be used for rice field, corn and soybean, cereal, sunflower, potato, peanut, Cotton Fields seedling
Or postemergence weed control.
Safety effect
Under greenhouse experiment, test plant rice paddy seed is planted in plastic tank, the 4- leaf phase is grown in plastic tank.
In this stage, by individual proxazuron-methyl, clefoxidim, proxazuron-methyl+clefoxidim, proxazuron-methyl+clefoxidim
The composition of+cloquitocet_mexyl, is administered to test plant.After applying 3 weeks, evaluation herbicide is measured to the plant of crop using percentage
Toxicity.100% indicates that test plant is completely dead, and 0% indicates plant-less toxicity effect.
As can be seen that the combination of proxazuron-methyl and clefoxidim, improves proxazuron-methyl or clefoxidim and farming
The compatibility of object reduces or prevents proxazuron-methyl or clefoxidim to plant, the useful crop of the useful crop with its processing
Seed or useful crop other reproductive parts caused by damage.
Also, specific safener is suitable for the invention Herbicidal combinations.Therefore, the invention further relates to one kind for selecting
Selecting property prevents and treats the selective herbicidal composition of the weeds in useful crop especially rice crops, and the composition contains the phonetic sulphur of promazine
Grand, clefoxidim, and it is selected from cloquitocet_mexyl above-mentioned, benoxacor, fenclorim, dichlormide, mefenpyrdiethyl, double isoxazolyl benzenesulfonamides
The safeners such as acid, study on brassinolide, the composition can protect crop (rather than weeds) to make from the phytotoxicity of herbicide
With further relating to the composition in the application for preventing and treating the undesirable plant in useful crop.
