Description

A kind of Herbicidal combinations

Technical field

The present invention relates to a kind of Herbicidal combinations.The invention further relates to a kind of method for controlling undesirable plant.

Background technology

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.

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.Promazine Sulfometuron Methyl, molecular formula are C₁₆H₁₈O₅N₇SCl, its molecular structure are as follows：

（I）

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, propanil；3rd, promazine Sulfometuron Methyl+propanil.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 propanil with certain dosage when alone to target weeds；

E₀For promazine Sulfometuron Methyl and theoretical value during two kinds of pharmacy mix of propanil to target weeds fresh weight inhibition；

E is promazine Sulfometuron Methyl and measured value during two kinds of pharmacy mix of propanil 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.）.

The activity of the rice barnyard grass of resistance is produced to propanil

Activity to Semen Euphorbiae

The activity of the Sagittaria trifolia L. Var. Angusti-folia(Sieb.) Kitag.(Sagittaria sagittifolia L.) of antagonism sulfonylureas and barnyard grass against the enemy

The activity of the Herba Cyperi Difformiss of antagonism sulfonylureas

Result of the test shows：Promazine Sulfometuron Methyl and propanil are 1:1-1:In the range of 100, 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 of weeds and barnyard grass against the enemy 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 4- leaf phases are grown in plastic tank.In this stage, by single promazine Sulfometuron Methyl, propanil, promazine Sulfometuron Methyl+propanil 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 propanil, the compatibility of promazine Sulfometuron Methyl and crops is improved, reduces 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.
