Description
Technical field
The present invention relates to agriculture chemical compounding technical field, particularly relate to a kind of bactericidal composition that contains nitre benzene bacterium ester and tetraconazole.
Background technology
Nitre benzene bacterium ester (meptyldinocap, 2-different pungent-4,6-dinitrophenyl-2-butenoate (2,4-dinitro-6-(1-methylheptyl) phenylcrotonate, 2,4-DNOPC), CAS:131-72-6) be non-internal-absorting miticide, there is certain contact bactericidal action simultaneously.Gai Yaoyou The Dow Agrosciences, LLC. exploitation, nitre benzene bacterium ester is one of isomer with high bioactivity of separating from 6 kinds of isomer of sterilization (mite) agent karathane (dinocap, CAS:39300-45-3).Be mainly used in preventing and treating two spotted spider mite and the powdery mildew of apple, oranges and tangerines, pears, grape, cucumber, muskmelon, watermelon, pumpkin, strawberry, rose and ornamental plants, mulberry tree powdery mildew and eggplant two spotted spider mite are had to good control efficiency, also there is the effect of killing mite ovum simultaneously.
Tetraconazole (Tetraconazole; 2-(2; 4-dichlorophenyl)-3-(1H-1,2,4-triazol-1-yl) propyl group 1; 1; 2,2 ,-tetrafluoro ethyl ether) belong to second generation triazole bactericidal agent; fungicidal spectrum is wide, efficient, have protection and therapeutic action, and inhales conductive performance in having well.Be suitable for cereal crop as wheat, barley, oat, rye etc., fruit tree is as banana, grape, pears, apple etc., and vegetables are as melon, beet, ornamental plants etc.Can prevent and treat Erysiphe, Puccinia, Rhynchosporium spp．, nuclear cavity Pseudomonas and the microbial disease of Septoria as wheat powdery mildew, loose smut of wheat, wheat rust, the bunt of wheat, wheat grain husk blessing disease, barley leaf blotch, loose smut of barley, barley banded sclerotial blight, maize head smut, head smut of sorghum, melon and fruit powdery mildew, sigatoka, alternaria leaf spot of apple, pear scab and grape powdery mildew etc.Both can process by cauline leaf, and also can make seed treatment and use.
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 nitre benzene bacterium ester and tetraconazole and carry out compositely on the basis of lab screening and field trial, have obvious synergistic effect.And about the composite bactericidal composition of nitre benzene bacterium ester and tetraconazole and application, there is no at present people reported.

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;

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: (the nitre benzene bacterium ester of take is standard medicament, and its toxicity index is 100):
The EC of the toxicity index of tetraconazole (TI)=nitre benzene bacterium ester
50the EC of/tetraconazole
50* 100
The EC of true toxicity index (ATI)=nitre benzene bacterium ester of M
50the EC of/M
50* 100
TI * P tetraconazole of TI * P nitre benzene bacterium ester+tetraconazole of theoretical toxicity index (TTI)=nitre benzene bacterium ester of M
TTI * 100 of the ATI/M of the co-toxicity coefficient of M (CTC)=M
In formula:
M is nitre benzene bacterium ester and the mixture of the different proportionings of tetraconazole
P nitre benzene bacterium ester is nitre benzene bacterium ester shared ratio in mixture
P tetraconazole is tetraconazole shared ratio in mixture.
2.1 toxicity test results
Table 1 tetraconazole and the toxicity test of nitre benzene bacterium ester 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 nitre benzene bacterium ester and tetraconazole as 1:10～10:1 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.
