Weeds in paddy field species is a lot, and paddy field weeding is a great problem in production.Chemical method weeding is the Main Means for controlling weeds.But in recent years, already lead to a lot of weeds and develop immunity to drugs as some herbicide kind large area are used alone.Meanwhile, grass when weeds occur is mutually complicated, and the mixed life of grassy weed, broad leaved weed, dried tuber multiclass weeds, the use of single variety herbicide can not solve farmland weed, can show defect in a certain respect and limitation.
On the other hand, for rice section field crop, the herbicide of particularly rice terrace needs the selectivity with height.Although poisoning energy management of weeds will not be brought when herbicide is usually used to crop, also can produce poisoning to crop due to due to gas phase, environment, misuse etc. are various sometimes.For herbicide especially for fertility suppressive, poisoning is easily produced under conditions of moisture excess.Accordingly, it would be desirable to develop one kind also will not produce poisoning, but energy management of weeds under above-mentioned mal-condition to crop, there is between crops and weeds the herbicide of high selectivity.
Promazine Sulfometuron Methyl(Propyrisulfuron)It is by the pyrimidine radicals sulfonylurea herbicide of SUMITOMO CHEMICAL chemistry exploitation, is mainly used in rice terrace and prevents and kill off the grass family such as barnyard grass and broad leaved weed.The product consumption is low, has good preventive effect to the weeds that sulfonylurea herbicide known to some produces resistance.Promazine Sulfometuron Methyl has good preventive effect to annual and perennial paddy field weed, such as barnyard grass and ticklish Corm Eleocharitiss, Rhizoma sagittariae sagittifoliae etc..Though promazine Sulfometuron Methyl belongs to sulfonylurea herbicide, which still has good activity to the weeds that sulfonylurea herbicide known to some produces resistance.Promazine Sulfometuron Methyl is mainly used for the herbicide that early metaphase is disposably killed, and can be used to make the pesticidal preparations product such as suspending concentrate or large-scale tablet, is directly thrown to field.

Biological Examples
Pre-emergence test:
Under greenhouse experiment, test plant is seeded in Seedling alms bowl.Standard soil is used as cultivation matrix.In the bud last stage, herbicide is administered to individually or in combination soil surface.Soil surface keeps certain water yield to simulate the water yield under field test in rice terrace.The consumption of herbicide depends on optium concentration determined by under field or greenhouse experiment.Test in post-evaluation in 2 ~ 4 weeks(100% effect=plant is completely dead;0% effect=plant-less toxicity is acted on).The combination of promazine Sulfometuron Methyl and triaziflam shows, than more preferable preventive effect is administered alone, to show obvious potentiation in this test.
When the Herbicidal combinations of the present invention are applied before rudiment, can entirely prevent that weeds emerge or weed growth to cotyledon period and then stops growing and completely death after 3 ~ 4 weeks.
After seedling is tested
Using potted plant cauline leaf process method (NY/T 1155.4-2006):In the built-in quantitative soil of the polypots of high 6cm, diameter 9cm, by 15 ~ 20 sowings of seed of unifacial leaf and dicots weeds in polypots, warm indoor cultivation is placed on after the thick fine earths of 0.5 ~ 1cm of lid, treat that weeds length carries out stem and leaf spraying treatment to 2 ~ 4 leaf phases, per alms bowl spraying liquid 1mL, often process and be repeated 4 times, and process without medicament is set for compareing.Warm indoor cultivation, the growing state of routine observation target weeds, range estimation target damage symptoms and growth inhibited situation after 21d being placed in after process, and claiming aerial partss fresh weight or strain fresh weight, toxicity action of the medicament to target weeds is evaluated with target fresh weight inhibition.
Three kinds of reagents are prepared according to constant weight percentage ratio:1st, promazine Sulfometuron Methyl;2nd, triaziflam;3rd, promazine Sulfometuron Methyl+triaziflam.Afterwards by above-mentioned each reagent dilute with water, medicament diluent is obtained.
Investigation method:
Range estimation target damage symptoms and growth inhibited situation after test process 21d, and claim aerial partss fresh weight, calculate fresh weight inhibition (%).
" CalculationSynergistic and are based on to the evaluation of the mixed potentiation for applying middle display of two or more herbicidal active components
Antagonistic Response of Herbicide Combinations”(Weeds
15/1 (1967), S.R.Colby) described in Colby ' s methods determine.
In formula, X is fresh weight inhibition of the promazine Sulfometuron Methyl with certain dosage when alone to target weeds;
Y is fresh weight inhibition of the triaziflam with certain dosage when alone to target weeds;
E0For promazine Sulfometuron Methyl and theoretical value during two kinds of pharmacy mix of triaziflam to target weeds fresh weight inhibition;
E is promazine Sulfometuron Methyl and measured value during two kinds of pharmacy mix of triaziflam to target weeds fresh weight inhibition.
If the control of weeds rate (E) of the reality that observes in biologic test exceedes uses the calculated desired value (E of Colby ' s methods0), then it represents that summation of the effect of Herbicidal combinations more than each agent effectiveness, it means that compositionss have potentiation.
Important noxious plant of the Herbicidal combinations of the present invention for following wide spectrum(Grassy weed, broad leaved weed, sedge weed) 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), Herba Abutili (Abuthilon
Theophrasti), the Sagittaria trifolia L. Var. Angusti-folia(Sieb.) Kitag.(Sagittaria sagittifolia L.) of anti-sulfonylureas(Sagittariatrifolia), Rhizoma Alismatis(Oriental Waterplantain Rhizome), anti-sulfonylureas Herba monochoriae vaginaliss(Herb of Pygmy Arrowhead), Monochoria korsakowii(Monochoria korsakowii), Lindernia procumbens (Krock.) Phillcox.(Lindernia
procumbens), Herba Solani Nigri (Solanum nigrum L.), firefly Lin(Scirpus juncoides Roxb), anti-sulfonylureas Herba Cyperi Difformiss(Cyperus
Difformis L.), Herba chenopodii(Chenopodium alum L.), wild oat(Avena fatua L.), Herba Galii Teneri(Galium
aparine L. var. tenerum Gren.et (Godr.) Rebb.), Veronica persica(Veronica persica).
Activity to rice barnyard grass
Activity to Semen Euphorbiae
Activity to Herba Digitariae
The activity of the Herba Cyperi Difformiss of antagonism sulfonylureas
Activity to Veronica persica
Result of the test shows:Promazine Sulfometuron Methyl and triaziflam are 1:100-100:In the range of 1, prevent and kill off grassy weed, the broad leaved weed of anti-sulfonylureas, anti-sulfonylureas sedge weed and show obvious potentiation, which effectively ensure that the preventing and treating of the weeds to the anti-sulfonylurea herbicide in current part, improve the effect of antagonism weed control
Summary, the Herbicidal combinations of the present invention, activity when preventive effect is administered alone better than each component, the test of pesticide effectiveness verifies which is combined with potentiation, expands control of weeds spectrum, a dispenser and prevents and kill off the crop fields grass family, broad leaved weed and sedge weed, reduces spraying times, reduce cost accounting, slow down the generation of Weed Resistance, good to crop safety, meet the security requirement of pesticidal preparations.Can be used for rice field, corn and soybean, corn, Helianthi, Rhizoma Solani tuber osi, Semen arachidis hypogaeae, the closing weeding of Cotton Fields before seedling or postemergence weed control.
Safety effect
Under greenhouse experiment, test plant rice paddy seed is planted in plastic tank, the 3- leaf phases are grown in plastic tank.The water yield in plastic tank is the growth of enough crops.In this stage, by single promazine Sulfometuron Methyl, triaziflam, promazine Sulfometuron Methyl+triaziflam compositionss, be administered to test plant.After applying 3 weeks, evaluation phytotoxicity of the herbicide to crop is measured using percentage rate.100% represents that test plant is completely dead, and 0% represents plant-less toxicity effect.
It can be seen that, promazine Sulfometuron Methyl and the combination of triaziflam, improve the compatibility of promazine Sulfometuron Methyl and crops, reduce or prevent promazine Sulfometuron Methyl to the infringement caused by other reproductive parts of plant, the seed of useful crop or useful crop with its useful crop for processing, improve the safety to Oryza sativa L..
