Description
Technical field
The present invention relates to a kind of bactericidal composition, especially contain the bactericidal composition of Acibenzolar and a kind of pyridines bactericide, belong to the disinfectant use in agriculture field.
Background technology
Powdery mildew is the plant disease that is caused by the Erysiphaceae in the fungi (Erysiphacesae).Powdery mildew is widely distributed in the whole world, and the dicotyledon of causing harm is particularly general.The main powdery mildew of China has the Cereal powdery mildew that is caused by standing grain powdery mildew (Ery-siphe graminis); The powdery mildew of the various plants such as melon, the beans that is caused by Siberian cocklebur monofilament shell (Sphaerothecafuliginea), crudefiber crop; The grape powdery mildew that is caused by grape snag shell (Uncinula necator); The powdery mildew of more than the 80 kind of trees such as the mulberry that is caused by hazel ball pin shell (Phyllactinia corylea), pears, persimmon, walnut, chestnut, lichee, papaya papaw; Powdery mildew of the Flowers of Rosa that is caused by rose monofilament shell (Sphaerotheca pannosa) etc.
Blade produced yellow point when powdery mildew just occured, and then enlarged to develop into circle or oval scab, and the mould layer of adularescent powdery is given birth on the surface, is conidiophore and the conidium of germ, and rear scab flavescence brown is the cleistothecium of germ.Mildew is early stage disperses separately, after be unified into a large mildew, even can cover full leaf, have a strong impact on photosynthesis, eubolism is interfered, cause early ageing, output incurs loss.
Downy mildew is that vegetables produce upper a kind of most important disease.Downy mildew all can occur to each stage of results from seedling, and it is heavier to be injured with strain.The blade of mainly causing harm is developed to upper leaf by base portion.Their early stage forms light yellow subcircular to the polygonal scab on the blade face, blade back produced the mould layer of white shape when there was dampness in the air, sometimes can spread to the blade face.The later stage scab is in flakes withered, is yellowish-brown, the withered and yellow death of whole siphonal lobes when serious.The easily morbidities such as field planting is overstocked, it is too early, excessive to water after the field planting, soil moisture large, impeded drainage.Spring is early summer or the easiest generation of continuous rainy weather in autumn not.
Epidemic disease mainly refers to by the fungus-caused class disease of Phytophthora (Phytophthora), mainly cause plant flowers, really, the quick necrosis of leaf section tissue and rotting.High humidity is to affect the principal element that disease occurs and propagates.Wherein melon epidemic disease and potato late blight are important diseases.
In the control of powdery mildew, downy mildew, epidemic disease, mainly rely on the medicaments such as benzimidazole, triazole type, metalaxyl, dimethomorph, mancozeb.These medicaments are because long-term use has produced pesticide resistance in various degree, and control efficiency reduces.Simultaneously a large amount of uses of medicament have increased residue of pesticide, and the harm food security has increased the weight of environmental pollution.

Field application examples 3: the composite field control effectiveness test to capsicum epidemic disease of Acibenzolar and fluazinam
Choose the just plot of morbidity of capsicum epidemic disease.Test medicine and consumption see Table 2, and 20 square metres of each residential quarter areas are repeated in 4 residential quarters of every processing.Carry out the dispenser first time at the disease initial stage of origination, the complete stool even spraying till being sprayed onto blade and dripping, is treated to blank with clear water.Execute for the second time medicine after 7 days.The incidence of 7 days investigation capsicum epidemic diseases behind the medicine before first time medicine and for the second time.5 samplings are adopted in every residential quarter, every some investigation 2 strains, and all blades are investigated in every strain, and the percentage that accounts for whole leaf area with lesion area comes the classification record.Calculate and respectively process 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 more than 50% of whole leaf area.
The drug effect computational methods:
As can be seen from Table 3: Acibenzolar, fluazinam single dose are respectively 73.21%, 77.03% to the preventive effect of capsicum epidemic disease, and embodiment of the invention bactericidal composition all is significantly increased on preventive effect, and minimum preventive effect is 85.77%, has been up to 92.33%.The result of field trial fully shows, Acibenzolar and fluazinam are composite to have significant synergistic function afterwards to capsicum epidemic disease, and in the situation that the mu effective ingredient consumption reduces, control efficiency significantly improves.Field investigation finds that composition can also doublely be controlled pepper powdery mildew.Therefore, the present composition has the beneficial effect that reduces cost, delaying drug resistance, minimizing spraying times and residue of pesticide.
