Description

A kind of bactericidal composition that contains prothioconazoles and cyazofamid
Technical field
The present invention relates to agriculture chemical compounding technical field, particularly relate to a kind of bactericidal composition that contains prothioconazoles and cyazofamid.
Background technology
Prothioconazoles is a kind of New-type wide-spectrum triazolinthione series bactericidal agent of Beyer Co., Ltd's development, its chemistry (RS)-2-(2-(1-chlorine cyclopropyl)-3-(2-chlorphenyl)-2-hydroxypropyl-1-2-dihydro-3-1,2,4-triazole-3-thioketones by name.Prothioconazoles toxicity is low, and without teratogenesis, mutagenesis type, to embryo's avirulence, to human and environment safety.Prothioconazoles is mainly used in preventing and treating cereal crop as numerous diseases such as wheat, barley, rape, peanut, paddy rice and legume crops.Almost all wheat class diseases are had to good control efficiency, as the powdery mildew of Wheat and barley, banded sclerotial blight, fusarium wilt, leaf spot, rust, stalk break, net blotch, moire disease etc.Can also prevent and treat the soil-borne disease of oily Lay and peanut, as stalk break, and main foliage disease, as gray mold, black spot, brown spot, balck shank, stalk break and rust etc.
Cyazofamid is the sulphaguanidine azoles fungicide that Japanese Ishihara Sangyo Kaisha, Ltd. produces; super protective fungicide; its chemistry chloro-2-cyano group-N of 4-by name; N-dimethyl-5-p-methylphenyl imidazoles-1-sulfonamide; cyazofamid is mitochondrial respiratory inhibitor; the all vegetative stages of oomycetes are all had to effect, and the germ that metalaxyl is produced to resistance or sensitivity all has activity.To downy mildew, epidemic disease, club root, damping off etc. have special efficacy, for the bacteria-treating on potato, grape, vegetables (cucumber, Chinese cabbage, tomato, onion, lettuce), lawn.To crop, the mankind, Environmental security.
Using chemical agent is the most effectively means of controlling plant diseases.But long-term use single chemical bactericide continuously high dose, easily cause the problems such as residual, the environmental pollution of medicament and resistance to pesticide resistance fungi development.Reasonably chemical bactericide is composite or be mixed and have expansion fungicidal spectrum, improve control efficiency, extend the optimum period for applying fertilizer, reduce dosage, reduce poisoning, reduce residual, delay Antifungal resistance and the positive feature such as drug-fast generation and development, bactericide compounded is one of the effective method the most addressing the above problem.Exploitation new product bactericide price is constantly soaring, and by contrast, exploitation is efficient with research, low toxicity, low-residual composite be mixed there is small investment, the lead time is short and be subject to domestic and international attention, the numerous and confused dynamics that develops that strengthens.We filter out prothioconazoles and cyazofamid and carry out compositely on the basis of lab screening and field trial, have obvious synergistic effect.And about the composite bactericidal composition of prothioconazoles and cyazofamid and application, there is no at present people reported.
Summary of the invention
Based on above situation, the object of the invention is to provide a kind of new and effective pesticide sterilizing composite.Be mainly used in preventing and treating the diseases such as powdery mildew on the crops such as wheat, barley, vegetables, peanut, paddy rice, banded sclerotial blight, fusarium wilt, leaf spot, rust, stalk break, downy mildew, epidemic disease, gray mold.

For examination medium :
PDA medium :potato 200g, glucose 20g, agar 20g, water 1000ml.
AEA medium :dusty yeast 5g/L, glycerine 20mL/L, MgSO 40.25g/L, NaNO 36g/L, KCl 0.5g/L, KH 2pO 41.5g/L, agar powder 20g/L, deionized water 1L.
1.3 test method
1.3.1 medicament preparation
First use the former medicine of acetone solution, according to the result of preliminary experiment, two appropriate former medicines are made into several different proportionings, then it is stand-by with acetone, each processing to be diluted to respectively to several concentration gradients.
Susceptible wheat cultivation, in pot for growing seedlings, is placed in to greenhouse and cultivates, and plant grows to three to four leaf after dates, gathers the blade of identical leaf age, for cultivation and the mensuration of wheat powdery mildew.
1.3.2 the cultivation of wheat powdery mildew and the preparation of spore suspension
Wheat powdery mildew adopts plants method to cultivate under 20 ℃, the condition of 12h alternation of light and darkness, and every 30 d turn culture 1 time.During inoculation, with the conidium on sterile water wash-out incidence of leaf, being mixed with spore concentration is l * 10 6the suspension of individual/mL.
1.3.3 strains tested sensitivity testing
Adopt leaf dish moisturizing method to carry out toxicity test.First the blade of collection is prepared into the leaf dish that diameter is 1.5cm, mix at random, be placed in respectively the series concentration liquid configuring and soak lh, 50 leaf dishes of each concentration, test is with the blank that is treated to of adding medicine not, after immersion finishes, leaf faces up and puts on the wetting blotting paper of identical liquor strength, liquid on leaf dish is blotted, the spore suspension l0L preparing is inoculated in to leaf dish central authorities, and room temperature is placed after 5 min, is placed under 20 ℃, the condition of 1 2h alternation of light and darkness and cultivates, after 10d, measure the onset area on leaf dish, calculate EC 50.
The percentage that accounts for leaf disc area according to lesion area is divided sick level
0 grade: anosis;
1 grade: sorus area accounts for below 5% of whole leaf area;
3 grades: sorus area accounts for below the 6%-10% of whole leaf area;
5 grades: sorus area accounts for below the 11%-20% of whole leaf area;
7 grades: sorus area accounts for below the 21%-50% of whole leaf area;
9 grades: sorus area accounts for the more than 50% of whole leaf area;
1.3.4 mixture toxicity test and interpretation of result
By single dose toxicity test method, according to mixed ratio, carry out the toxicity test of mixture.
If contrast lethality <5%, does not proofread and correct, contrast lethality, between 5%-20%, is proofreaied and correct by formula 2, contrast lethality >20%, and test need be reformed.
The logarithm value of drug concentration (mg/L) of take is independent variable x, and the probability value of corrected mortality of take is dependent variable y, sets up respectively virulence regression equation formula, adopts DPS software to calculate the EC of single dose and each proportioning mixture 50according to the abundant method of Sun Yun, calculate co-toxicity coefficient (CTC).Co-toxicity coefficient CTC, computing formula is as follows: (take prothioconazoles as standard medicament, its toxicity index is 100):
The EC of the toxicity index of cyazofamid (TI)=prothioconazoles 50the EC of/cyazofamid 50* 100
The EC of true toxicity index (ATI)=prothioconazoles of M 50the EC of/M 50* 100
TI * P cyazofamid of TI * P prothioconazoles+cyazofamid of theoretical toxicity index (TTI)=prothioconazoles of M
TTI * 100 of the ATI/M of the co-toxicity coefficient of M (CTC)=M
In formula:
M is prothioconazoles and the mixture of the different proportionings of cyazofamid
P prothioconazoles is prothioconazoles shared ratio in mixture
P cyazofamid is cyazofamid shared ratio in mixture.
2.1 toxicity test results
Table 1 cyazofamid and the prothioconazoles toxicity test to wheat powdery mildew
As can be seen from the table, the result of the test of different proportion proportioning shows, in active ingredient ratio, dilute respectively and all show stronger synergistic effect, wherein take prothioconazoles and cyazofamid as 1:20~20:1 time the good suggestion of synergistic effect suitable proportion 1:10~10:1 left and right mixture preparation is carried out to further field control effectiveness test, to evaluate its field practical application effect.
