Description
Technical field
The present invention relates to agriculture chemical compounding technical field, particularly relate to a kind of bactericidal composition that contains prothioconazoles and Prochloraz.
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 by name, 2,4-triazole-3-thioketones, prothioconazoles toxicity is low, without teratogenesis, and 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.
Prochloraz is a kind of wide-spectrum bactericide, its chemical name: N-propyl group-N-[2-(2,4,6-Trichlorophenoxy) ethyl]-imidazoles-1-formamide, the disease that various crop is caused by sac fungi and imperfect fungus has obvious preventive effect, also can be mixed with most of bactericide, bactericide, Insecticides (tech) & Herbicides (tech), all there is good control efficiency.Multiple diseases on field crop, fruit and vegetable, turf and ornamental plants is had to treatment and eradicant action.Main control gourd, fruit and vegetable anthracnose, leaf spot, also can prevent and treat bakanae disease of rice, rice blast etc.Citrus anthracnose, blossom-end rot, penicilliosis, green mould, banana anthracnose, leaf spot, mango anthracnose, leaf spot of peanut, the vegetables anthracnose such as capsicum, eggplant, muskmelon, tomato, Strawberry anthracnose, bakanae disease of rice, rice blast, sclerotinia rot of colza, leaf spot, mushroom brown spot, apple anthracnose, pear scab etc.
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 problem such as residual, environmental pollution and resistance to pesticide resistance fungi development of medicament.Reasonably the composite or mixture of chemical bactericide has expansion fungicidal spectrum, improve control efficiency, extend the optimum period for applying fertilizer, reduce dosage, reduce poisoning, reduce residual, delay the positive feature such as Antifungal resistance and 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, composite and the mixture of low toxicity, low-residual has small investment, the lead time is short and be subject to domestic and international attention, and numerous and confused increasing develops dynamics.We filter out prothioconazoles and Prochloraz and carry out compositely on the basis of lab screening and field trial, have obvious synergistic effect.And there is no at present people about the composite bactericidal composition of prothioconazoles and Prochloraz and application 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 powdery mildew, banded sclerotial blight, fusarium wilt, leaf spot, rust, stalk break, stalk break, rice blast and gourd, fruit and vegetable anthracnose, the leaf spot etc. of cereal crop.

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 DEG C, the condition of 12h alternation of light and darkness, and every 30 d turn culture 1 time.When 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 DEG C, the condition of 1 2h alternation of light and darkness and cultivates, after 10d, measure the onset area on leaf dish, calculate EC
50.
On the basis of preliminary experiment, respectively single dose prothioconazoles and Prochloraz are carried out to toxicity test in order to upper method, the two EC
50value is respectively 7.3592 ㎎/l and 12.0329 ㎎/l.
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
Carry out the toxicity test of mixture according to mixed ratio by single dose toxicity test method.
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.
Taking the logarithm value of drug concentration (mg/L) as independent variable x, taking the probability value of corrected mortality as dependent variable y, set up respectively virulence regression equation formula, adopt DPS software to calculate the LC of single dose and each proportioning mixture
50calculate co-toxicity coefficient (CTC) according to the abundant method of Sun Yun.Co-toxicity coefficient CTC, computing formula is as follows: (taking prothioconazoles as standard medicament, its toxicity index is 100):
The LC of toxicity index (the TI)=prothioconazoles of Prochloraz
50the LC of/Prochloraz
50× 100
The LC of true toxicity index (ATI)=prothioconazoles of M
50the LC of/M
50× 100
TI × P Prochloraz of TI × P prothioconazoles+Prochloraz of theoretical toxicity index (TTI)=prothioconazoles of M
TTI × 100 of the ATI/M of co-toxicity coefficient (CTC)=M of M
In formula:
M is prothioconazoles and the mixture of the different proportionings of Prochloraz
P prothioconazoles is prothioconazoles shared ratio in mixture
P Prochloraz is Prochloraz shared ratio in mixture.
2.1 toxicity test results
Table 1 Prochloraz 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, dilute respectively and all show stronger synergistic effect in active ingredient ratio, wherein taking prothioconazoles and Prochloraz 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.
3, field trial control wheat powdery mildew, the experimental result of rice blast
3.1 field trial control wheat powdery mildews
3.1.1 test method
