Description
Technical field
The invention belongs to the pesticide herbicide technical field, be specifically related to a kind of Herbicidal combinations that contains Flumetsulam.
Background technology
Flumetsulam (Flumetsulam) is Flumetsulam again, and chemical name is: 2 ', 6 '-two fluoro-5-methyl (1,2,4) triazol (1,5-α) pyrimidines-2-sulfonanilide, molecular formula C

The test of pesticide effectiveness of above-mentioned different FORMULATION EXAMPLE
Above-mentioned FORMULATION EXAMPLE 1-19 is made an experiment through the method that Toxicity Determination and field efficacy combine, in order to prove the drug effect of Herbicidal combinations according to the invention.
(1) Toxicity Determination:The present invention adopts soil pouring method to carry out Toxicity Determination.
Supply the examination weeds:Confession is planted experimentally son earlier with 40 ℃ of water seed soakings, use dark gauze shading then, be placed in the culture dish that is covered with sponge, water is moistening to carry out vernalization, waits the seed back that shows money or valuables one carries unintentionally to sow.Test soil quantitatively is filled to 4/5 place of basin alms bowl.Adopt basin alms bowl bottom infiltrating irrigation mode, it is fully moistening to saturation state that soil is in.In soil surface, earthing 0.5cm after planting moves into the conventional cultivation in greenhouse with pretreated barnyard grass grass seed uniform broadcasting; Adopt the moisturizing of basin alms bowl bottom infiltrating irrigation mode, make soil moistening fully, place 30 ℃ of temperature; Cultivate in light/dark greenhouse than 14h/10h, after planting 10d carries out thinning and decides strain, and making weeds density is 20 strains/basin; Treat that weeds grow to the 2-3 leaf, carry out dispenser and handle.
Implementation method:With weed seed by per 20 as a processing, each is handled 3 times and repeats, and plants in basin.
The mensuration of indoor virulence of the present invention adopts the absolute value investigation method, according to survey data, calculates strain preventive effect that each is handled according to following formula, and result of calculation keeps behind the decimal point 2.In the formula (1): E-strain preventive effect; C-contrast weeds acrial part weeds strain number; T-processing weeds acrial part weeds strain number.
Computational methods adopt the abundant method of Sun Yun (1960) to estimate the mixture synergism effect.Calculate mixture actual measurement toxicity index according to following formula (2).In the formula (2): ATI------mixture actual measurement toxicity index; The EC50 of S---standard herbicide, unit are every liter (mg/L) of milligram; The EC50 of M---mixture, unit are every liter (mg/L) of milligram.
Calculate the theoretical toxicity index of mixture according to following formula (3).In the formula (3): TTI------the theoretical toxicity index of mixture; TI
A---A medicament toxicity index; P
A---the percentage composition of A medicament in mixture, unit are percentage (%); TI
B---B medicament toxicity index; P
B---the percentage composition of B medicament in mixture, unit are percentage (%).
Calculate the co-toxicity coefficient of mixture according to following formula (4).In the formula (4): CTC---co-toxicity coefficient; ATI---mixture actual measurement toxicity index; The theoretical toxicity index of TTI---mixture.
Statistical analysis adopts DPS software that the logarithm value of drug dose and the probability value of preventive effect are carried out regression analysis, calculates EC50, EC90 and 95% confidence limit (seeing table 1).Composite dose co-toxicity coefficient (CTC)>=120 shows as synergistic effect; CTC≤80 show as antagonism; 80＜CTC＜120 show as summation action (seeing table 2).
Subordinate list 1 is implemented the toxicity test result of medicament virulence to weeds

(2) field control effectiveness test:
1,Soybean of the present invention field drug effect implementation method: before soybean is broadcast the back seedling with the FORMULATION EXAMPLE 1-19 according to the invention processing of spraying; Observe, write down test data; Calculate the preventive effect of medicament, the result sees table 3 preventive effect of each the single agent of B component (provided in the table 3 as a comparison).
Peanut of the present invention field drug effect implementation method: carry out cauline leaf spraying processing with FORMULATION EXAMPLE 1-19 according to the invention seedling stage at peanut; Observe, write down test data; Calculate the preventive effect of medicament, the result sees table 4 preventive effect of each the single agent of B component (provided in the table 4 as a comparison).
The different FORMULATION EXAMPLE of table 4 are to the preventive effect of peanut field weed
Can find out that by table Flumetsulam and amide-type belong to the weed killer herbicide of two different effects mechanism, Flumetsulam belongs to triazolo pyrimidine class weed killer herbicide; Multiple annual and perennial broadleaf weed and nutgrass flatsedge there is special efficacy; And acetamide-group herbicides have special efficacy to barnyard grass grass and multiple grassy weed, and the grass that kills that has enlarged single agent after both make up is composed; Make standing grain, wealthy, Sha all can remove, have synergy and the effect that enlarges the weed killer herbicide scope.And through evidence, both are composite high to crop safety, and both composite co-toxicity coefficients show as synergistic effect greater than 120, have feasibility.
At last, need to prove: modification or the improvement on the basis of not departing from spirit of the present invention, made, apparent to those skilled in the art, therefore should all belong to the scope that requirement of the present invention is protected.
