Description
Technical field
The present invention relates to technical field of pesticide combination, particularly relate to a kind of bactericidal composition containing copper 8-hydroxyquinolinate and S-Ethyl ethylthio sulfonate.
Background technology
Copper 8-hydroxyquinolinate, for clamping together state organic copper bactericide, for preventing and treating the agricultural chemicals composition of apple tree ring spot etc.There is the features such as efficient, wide spectrum, safety, low toxicity, low-residual, to fungi, bacterial disease, all there is excellent control efficiency.The product mode of action is unique, forms fine and close diaphragm, kill pathogen in film in crop surface.Inner pathogen, suppress activity and the conduction of the main conduction thing of pathogen, thus kill pathogen.
S-Ethyl ethylthio sulfonate is a kind of highly effective bactericide with broad spectrum, can suppress tens of kinds of germs of the crops such as grain and oil, cotton, vegetables, flowers, medicinal material, tealeaves and silkworm industry, fishery.Extensively should have in water prevention seedling blight of rice disease, bakanae disease, rice blast, bacterial leaf-blight at present; Stinking smut, stripe disease; Fusarium and Verticillium wilts, fruit tree ring spot, anthracnose, leaf spot; The epidemic disease, bacterial wilt, blight dis-ease, fusarium wilt, anthracnose crops seedling stage damping off, damping off, root rot etc. of gourd, fruit and vegetable.
In the real process of agricultural production, using chemical agent is the most effective means of control plant pest, but is the generation of disease drug resistance by the problem that chemical control disease the most easily produces.In the chemical control of bacteriosis, years of researches are carried out both at home and abroad, although some antibacterium medicaments have started to enter practical stage, but the medicament of chemosynthesis has cycle long, the shortcoming such as cost is high, toxicity is large, environmental pollution is serious, can not meet the requirement of agricultural sustainable development far away.And long-term use single pesticidal preparations continuously high dose, easily cause the problems such as the remaining of medicament, environmental pollution and resistance to pesticide resistance fungi development.And by contrast, exploitation is efficient with research, low toxicity, low-residual composite and mixture has small investment, the lead time is short and be subject to domestic and international attention, numerous and confused increasing develops dynamics.We are on the basis of lab screening and field trial, filter out copper 8-hydroxyquinolinate and S-Ethyl ethylthio sulfonate carries out composite, have obvious synergistic effect.And about copper 8-hydroxyquinolinate and S-Ethyl ethylthio sulfonate composite composition pesticide and apply and there is no people at present and reported.
Summary of the invention
Based on above situation, the object of the invention is to provide a kind of new and effective composition pesticide, is mainly used in preventing and treating fruit tree putrefaction disease; Spot defoliation; Rice blast; Root rot; Cucurbits fusarium wilt; Cotton verticillium wilt; Jujube tree rust; Fruit white rot of grape; Panax pseudoginseng black spot; Tealeaves tea gall, forest rot, canker, gummosis, defoliation, woods seedling blight, dish Bacteria erwinia, avenae subsp.citrull, Xanthomonas oryzae, ring rot of apple germ, fusarium graminearum etc.

For making technical scheme of the present invention, object and advantage are clearly understood, the following specific embodiment of the present invention is described, but the present invention is not limited to these examples.The mode that effect experimental of the present invention adopts indoor biometrics and field trial to combine, if no special instructions, the ratio below mentioned is all ratio of quality and the number of copies.
Embodiment: copper 8-hydroxyquinolinate and S-Ethyl ethylthio sulfonate different ratio co-toxicity are tested.
1.1 test targets
Cucumber bacterial angular leaf spot bacterium (germ bacterial classification picks up from Jimo Yi Feng town, Qingdao of Shandong province cucumber booth, obtains through the Sheng Ce laboratory separation and purification of research and development centre of Hailir Pharmaceutical Group Co., Ltd.).
1.2 test method
The female medicine of 95% copper 8-hydroxyquinolinate, the female medicine of 98% S-Ethyl ethylthio sulfonate, is provided by Chemical Co., Ltd. Shandong Hailier.Add aqua sterilisa by purified slant tube bacterial classification, be made into former bacteria suspension, then be diluted to 107/rise bacteria suspension, for subsequent use.First be made into 1000mg/L mother liquor by after copper 8-hydroxyquinolinate and the water-soluble solution of the female medicinal sterile of S-Ethyl ethylthio sulfonate, dilute with sterile water again during use.(unit: mg/litre)
Copper 8-hydroxyquinolinate is mixed with S-Ethyl ethylthio sulfonate sets 5 assembly ratios altogether, and on the basis of preliminary experiment, each single dose and each proportioning establish 5 concentration process respectively, not contain the system of liquid for blank (maximum concentration with reference to chemicals treatment dilutes).Each concentration process repeats 4 times, under aseptic technique, each concentration gradient medicament is drawn 4ml successively respectively from low concentration to high concentration, add in the aseptic conical flask melted in advance containing 36ml sterilising medium, fully shake up, then pour into immediately in the culture dish of diameter 9cm, make corresponding pastille dull and stereotyped.Every ware add 107/rise bacterial suspension 200 μ L, then with after sterilizing triangular glass rod bacteria suspension in ware is pushed away even, be placed in 28 DEG C of insulating boxs and cultivate.Separately establish the process not containing medicament as blank.Each process repetition 4 times.
1.3 investigation method
Cultivate after 48 hours and culture dish is taken out, according to blank, observe bacteria colony count in each ware of each concentration.
Relative inhibition is calculated according to each process bacteria colony count:
1.4 synegism evaluation
The synergistic effect of pharmacy mix is evaluated according to the co-toxicity coefficient method (CTC) of Sun & Johnson (1960), namely CTC≤80 are antagonism, 80 < CTC < 120 are summation action, and CTC >=120 are synergistic effect.
Actual measurement toxicity index (ATI)=standard agent EC
50/ reagent agent EC
50* 100
In toxicity index * 100 mixture of theoretical toxicity index (the TTI)=medicament A of mixture the percentage composition+medicament B of A medicament toxicity index * 100 mixture in the percentage composition of B medicament
The theoretical toxicity index (TTI) * 100 of co-toxicity coefficient (CTC)=mixture actual measurement toxicity index (ATI)/mixture.
2.1 toxicity test results
Table 1 copper 8-hydroxyquinolinate and S-Ethyl ethylthio sulfonate are to the toxicity test of cucumber bacterial angular leaf spot bacterium
As can be seen from the table, the result of the test of different proportion proportioning shows, dilute respectively in active ingredient ratio and all show stronger synergistic effect, wherein with copper 8-hydroxyquinolinate: time S-Ethyl ethylthio sulfonate is 1:20 ~ 20:1, synergistic effect is best, suggestion carries out further field control effectiveness test to suitable proportion about 1:20 ~ 20:1 mixture preparation, to evaluate its field practical application effect.
