Description
Technical field
The invention belongs to plant protection arts, and in particular to it is a kind of prevent and treat bacterial diseases of crops bactericidal composition and
Its purposes.
Background technique
The fungicide kind for preventing and treating bacterial diseases of crops currently on the market is very limited, mainly includes four classes: 1) nothing
Machine copper agent；The most commonly used is copper agent, such medicament is at present just gradually replaced the medicament by safety.2) agricultural strepto-
Element, kasugarnycin, Zhongshengmycin etc.；A large amount of uses of these farm antibiotics may cause human body pathogen to medical antibiosis
Element generates interaction drug resistance, so country just gradually limits or forbid the use of these antibiotic.3) Yekuzuo series is bactericidal
Agent such as Yekuzuo, zinc thiazole, Thiodiazole-copper, this kind of fungicide are that the mainstream in the chemical agent of current prevention and treatment bacterial disease produces
Product, these effect of chemical control are good and highly-safe, but these chemical control higher costs, while using more than 20 years, one
Other medicament rotations are also required in fixed degree to use.4) copper 8-quinolinolate, the medicament can prevent and treat tomato late blight, Portugal simultaneously
Up to the present the bacterial diseases such as the fungal diseases such as grape downy mildew and cucumber bacterial angular leaf spot, citrus bacterial canker disease, are
By practice examining, bacterial disease effectively newest medicament is prevented and treated.
Rare new bacillary medicament listing, the mixture for developing new bactericide and Related product have in nearly 20 years
Important meaning.Although 8-hydroxyquinoline calcium just had the reported in literature of synthesis in 2012, it does not relate to agriculture application.
We started 8-hydroxyquinoline calcium in 2015 in cucumber bacterial angular leaf spot, citrus bacterial canker disease, rice leaf spot bacteria, water
Rice bacterial stripe, Characters of Erwinia chrysanthemi pv. zeae, wild cabbage bacterial soft rot, peach Bacterial septicaemia syndrome, watermelon angular leaf spot,
It carries out studying and having applied on June 29th, 2018 using patent (application number on the bacterial diseases such as Prospect on Kiwifruit Bacterial Canker
201810699172)；Nearly 2 years mixed with some conventional bactericidal compounds progress indoor biometrics and field by quinoline calcium
Application study shows that the quinoline calcium bactericide different from these mechanisms of action has fine miscibilty and synergistic function.Quinoline
The advantages of quinoline calcium is that safety is good, protective value is good, the lasting period is long, the disadvantage is that absorbability is poor, it is slow to work；And with some interior property compared with
After good, rapid-action medicament is used cooperatively, it can not only achieve the purpose that reasonable delaying drug resistance, moreover it is possible to it is climing to play quickly control disease
Prolong, the effect of holding effect cover crop health, provides better solution from for field diseases prevention and treatment.
Summary of the invention
The purpose of the present invention is to provide a kind of compositions for preventing and treating bacterial diseases of crops, this composition is than single
The fungicide synergy of component is obvious, while reasonable delaying drug resistance, moreover it is possible to play quickly control disease sprawling, holding effect protection is made
The effect of object health provides better solution from for field diseases prevention and treatment.
Under the technical scheme is that:
A kind of composition for preventing and treating bacterial diseases of crops, the composition include A and B two kinds of active components.Wherein live
Property ingredient A be quinoline calcium, active constituent B is in kasugarnycin, Zhongshengmycin, Xinjunan acetate, zinc thiazole, Thiodiazole-copper
It is a kind of；Weight ratio between two kinds of ingredients of A and B is 1:80~80:1.
Active components A is different from the compound structure type of active constituent B, and mechanism of action is different, and no interactions are anti-between the two
Property, the two compounding can expand fungicidal spectrum, improve medicament and control effect, and can delay the production of pathogen resistance to a certain extent
It is raw.
Another object of the present invention is that providing the preparation method of above-mentioned composition and its in prevention and treatment crops bacterium
Application in venereal disease evil.
Weight ratio in above-mentioned composition between two kinds of ingredients of active components A and active constituent B is 1:80~80:1, excellent
1:40~40:1 of choosing, further preferably 1:20~20:1, further preferably 15:1-1:10 are still more preferably 10:
1-1:5。
The active components A is 8-hydroxyquinoline calcium, hereinafter referred to as quinoline calcium.
The active constituent B in kasugarnycin, Zhongshengmycin, Xinjunan acetate, zinc thiazole, Thiodiazole-copper one
Kind.
The composition also includes insecticides adjuvant.
The composition is made of the active constituent of 10%~85% parts by weight and the insecticides adjuvant of 90%~15% parts by weight.
The dosage form of the composition is any one dosage form agriculturally allowed.
The dosage form is wettable powder, suspending agent, microcapsule suspending agent, suspoemulsion, water dispersible granules, aqueous emulsion, dense
