The sterilizing composition consists of effective components including (A) isopyrazam and (B) ethirimol or bupirimate or dimethirimol, wherein the mass ratio of the A to the B is (1:50)-(50:1). The composition is obvious in synergistic effect, high in control efficiency, suitable for preventing and treating various diseases on melons, fruits and vegetables, and particularly suitable for preventing and treating powdery mildew.
Description
Technical field
The present invention relates to a kind of bactericidal composition, relate in particular to a kind of application taking pyrazoles naphthalene bacterium amine and the phonetic phenol of second or bupirimate or dimethirimol as the bactericidal composition of main component.
Background technology
Powdery mildew is the plant disease being caused by the Erysiphaceae in fungi (Erysiphacesae).For example: the Cereal powdery mildew being caused by standing grain powdery mildew (Ery-siphe graminis); The powdery mildew of the various plants such as melon, the beans that caused by Siberian cocklebur monofilament shell (Sphaerotheca fuliginea), crudefiber crop; The grape powdery mildew being caused by grape snag shell (Uncinula necator): the powdery mildew of more than the 80 kind of trees such as the mulberry that caused by hazel ball pin shell (Phyllactinia corylea), pears, persimmon, walnut, chestnut, lichee, papaya papaw; The powdery mildew of the Flowers of Rosa being caused by rose monofilament shell (Sphaerotheca pannosa) etc.
In the control of powdery mildew, the main bactericide such as benzimidazole, triazole type, methoxy acrylate class that rely at present.These medicaments are because long-term use has produced pesticide resistance in various degree, and control efficiency reduces.In addition, the growth to crop in the time that using dosage is large of triazole type medicament has inhibitory action, easily causes poisoning.
Pyrazoles naphthalene bacterium amine (isopyrazam) is for having the pyrazol acid amide compounds of new chemical structure, molecular formula C

Embodiment
The pesticide active ingredient of different types of structure being carried out composite, is a kind of effective means that solves at present the problem such as cost and resistance in agricultural chemicals single dose application process.The pesticide active ingredient of different types of structure shows three kinds of type of action after mixing conventionally, i.e. summation action, synergistic effect and antagonism, but be specially which kind of effect, and unpredictable, only have by lot of experiments and just can know.Compound synergic is well filled a prescription, and can improve actual control efficiency, reduces the usage amount of agricultural chemicals, contributes to the generation of delaying drug resistance, is the important means of scientific prevention and cure damage by disease and insect.
The present composition has obvious synergistic function to Powdery Mildew etc., and is not only the simple addition of two kinds of pharmacy effects, and this can be clear that from the result of following toxicity test experiment very much.
Biologicall test example 1: the Toxicity Determination of composition to cucurbits powdery mildew bacterium
Subjects is powdery mildew of cucumber bacterium (Sphaerotheca fuliginea).
Test method: with reference to " the agricultural industry criteria NY/T1156.11-2008 of the People's Republic of China (PRC) ".Choose the consistent potted plant two leaf period cucumber seedlings of growth potential, under 50PSI pressure, spray with Potter spray tower, every basin 5mL.Each medicament arranges 5 concentration gradients.After 24h, carrying out inoculum density is 3 × 10
5the powdery mildew of cucumber bacterium conidial suspension of individual spore/mL.Taking the cucumber seedling that sprays equivalent clear water as blank.After inoculation, cucumber seedling being put into greenhouse cultivates.After 10d, according to the morbidity grade scale investigation disease index of powdery mildew of cucumber, and calculate control efficiency.
Powdery mildew of cucumber severity Scaling standard:
0 grade: blade is without scab;
1 grade: lesion area accounts for the area of whole blade below 5%;
3 grades: lesion area account for whole blade area 6%～10%;
5 grades: lesion area accounts for 11%～25% of whole blade area;
7 grades: lesion area accounts for 25%～50% of whole blade area;
9 grades: lesion area accounts for the more than 50% of whole blade area.
The expection effect (being theoretical control efficiency, %) of mixture of active principles use Colby formula determine and with the effect comparison of observing:
Colby formula: E=X+Y-X*Y/100
E: when active components A working concentration in composition is a, compositions contemplated effect when active component B working concentration is b.
X: effect when active components A using dosage is a.
Y: effect when active component B using dosage is b.
In the time that exceeding expection preventive effect, the actual control efficiency of observing illustrates that mixture has synergistic effect.
Toxicity test result referring to table 1 to table 3.
The composite pot experiment measurement result to powdery mildew of cucumber of table 1 pyrazoles naphthalene bacterium amine and the phonetic phenol of second
The composite pot experiment measurement result to powdery mildew of cucumber of table 2 pyrazoles naphthalene bacterium amine and bupirimate
The composite pot experiment measurement result to powdery mildew of cucumber of table 3 pyrazoles naphthalene bacterium amine and dimethirimol

Field application examples 5: the composite field control effectiveness test to powdery mildew of cucumber of pyrazoles naphthalene bacterium amine and dimethirimol
Test site Foshan.Test medicine and consumption are in table 8, and repeat 4 communities of every processing, 20 square metres of each community areas.Carry out dispenser for the first time at disease initial stage of origination, even spraying, till being sprayed onto blade and dripping, is treated to blank with clear water.After 7 days, execute medicine for the second time.Before the medicine for the first time and for the second time incidence of 7 days investigation powderys mildew of cucumber after medicine.Every community adopts 5 samplings, every some investigation two strains, and all blades are investigated in every strain, and the percentage that accounts for whole leaf area with lesion area carrys out classification record.Calculate each processing disease index and control efficiency.
Grade scale:
0 grade: without scab;
1 grade: lesion area accounts for below 5% of whole leaf area;
3 grades: lesion area accounts for the 6%-15% of whole leaf area;
5 grades: lesion area accounts for the 16%-25% of whole leaf area;
7 grades: lesion area accounts for the 26%-50% of whole leaf area;
9 grades: lesion area accounts for the more than 50% of whole leaf area.
Drug effect computational methods:
As can be seen from Table 8: pyrazoles naphthalene bacterium amine, dimethirimol single dose are respectively 76.3%, 73.2% to the preventive effect of powdery mildew of cucumber, and embodiment of the present invention bactericidal composition is all significantly increased in preventive effect, and minimum preventive effect is 85.4%, has been up to 89.9%.The result of field trial fully shows, pyrazoles naphthalene bacterium amine and dimethirimol are composite has significant synergistic function afterwards to powdery mildew of cucumber, and in the situation that mu effective ingredient consumption reduces compared with single dose, control efficiency significantly improves.Therefore, the present composition have reduce costs, the beneficial effect of delaying drug resistance, minimizing spraying times and residue of pesticide.
