Description
Technical field
The present invention relates to technical field of pesticide compounding, more particularly to a kind of for preventing and treating the sterilization group of Kiwi berry soft rot
Close object.
Background technique
Kiwi berry soft rot occurs mainly in the latter stage of ripening after kiwifruit fruit harvest, and the pulp inside fruit occurs soft
Corruption loses edible value, shows as the recess that little finger size occurs in pulp, peels off the epidermis of recessed portion, and sick portion center is milky white
Color is in around yellow green, and peripheral strong green is annular in shape, the soft corruption of pulp.Chemical prevention is the important means of control of plant disease, and
A certain single dose is long-term, single administration easily causes the drug resistance of disease, cause indirectly environmental pollution, disease it is rampant, at high cost again,
The problems such as crop safety declines.For prevention and treatment Kiwi berry soft rot, there are no more satisfactory methods at present, therefore, research one
The dedicated combination sterilization composition of kind is to control the feasible controlling mode of Kiwi berry soft rot.
Tetramycin (tetramycin) is the fermentating metabolism product of streptomysin Wuzhou subspecies of not absorbing water, containing there are many antibiotic,
Wherein macrolide tetraene antibiotic prevents and treats bacteriosis；Peptide pyrimidine nucleoside acids antibiotic prevents and treats fungal disease；Nitrogen-containing hetero
Cyclic aromatic series derivative antibiotic improves crop immunity, wide sterilization spectrum, to mastigomycetes, sac fungus and Deuteromycotina
Disease fungus known to three main kind of 26 kinds of fungi etc. has extremely strong killing effect.Be applicable in various crops a variety of fungies,
The prevention and treatment of bacteriosis.Especially to fruit tree putrefaction disease spot defoliation, bleeding disease, defoliation, rice blast, root rot, jujube
Set rust, fruit white rot of grape, Panax pseudoginseng black spot, cucurbits fusarium wilt, cotton verticillium wilt, tealeaves gall of tea, forest rot disease,
The fungal diseases special efficacys such as canker, woods seedling blight.
Tebuconazole is absorbability triazole pesticide bactericide, has and protects, treats, rooting out three zones, wide sterilization spectrum is held
The feature of effect phase length, the blade and root system that can run through plant absorb and conduct and be uniformly distributed in vivo, main logical
The demethylation for inhibiting sterol in disease fungus body is crossed, the formation of biomembrane is caused to be obstructed and play bactericidal activity.Tebuconazole energy
The a variety of rust of effectively preventing, powdery mildew, net blotch, root rot and wheat mildew are the effect pesticide sterilizings of Important Economic crop
Agent specific drug.
The bactericidal composition and application compounded about tetramycin with Tebuconazole there is no report at present.
Summary of the invention

Dark culturing in incubator.And using clear water as control.
Field control effectiveness test：The wherein compound proportion progress field control effectiveness test with synergistic effect is selected, divides 3 times and applies
Medicine, the 1st time is that Kiwi berry is beared fruit the phase, and the 2nd time is fruit expanding period, and the 3rd time is 20d before harvesting.And with 0.3% tetramycin,
80% Tebuconazole and clear water are as control.
1.4 investigation method
After 48h, colony diameter is measured with " right-angled intersection " method, calculates the EC of inhibiting rate and different proportion compound drug50, and
Calculate co-toxicity coefficient (CTC)；Field trial calculates the disease incidence and preventive effect of storage 20d different disposal after harvesting.
Inhibiting rate (%)=processing colony diameter/clear water compares colony diameter * 100；
The synergistic effect of pharmacy mix, i.e. CTC are evaluated according to the co-toxicity coefficient method (CTC) of (1960) Sun&Johnson
≤ 80 be antagonism, and 80 < CTC < 120 are summation action, and CTC >=120 are synergistic effect.
Survey toxicity index (ATI)=standard agent EC50/ reagent agent EC50*100；
Percentage composition+medicament B of A medicament in mixtures theoretical toxicity index (TTI)=medicament A 100 mixture of toxicity index *
100 mixture of toxicity index * in B medicament percentage composition；
Co-toxicity coefficient (CTC)=mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI) * 100；
Diseased fruit rate (%)=morbidity fruit number/fruit sum * 100；
Preventive effect (%)=(control group disease incidence-processing group disease incidence)/check plot diseased fruit rate * 100.
2 test results
2.1 The Toxicity Determination result
1 tetramycin of table compounds the virulence to grape seat chamber bacterium with Tebuconazole
As it can be seen from table 1 tetramycin：Tebuconazole is 1~5:It is compounded between 5~1 ratios, co-toxicity coefficient (CTC) value is big
In 120, there is synergistic function.
2.2 field efficiency test results
Field efficacy of 2 different disposal of table to Kiwi berry soft rot
As can be seen from Table 2, tetramycin compounds the disease incidence that can reduce Kiwi berry soft rot with Tebuconazole, improves field
