Abstract
The invention discloses a bactericide for controlling apple altermaria leaf spots, which is characterized in that the bactericide comprises iprodione and tebuconazole; the weight percentage of iprodione to tebuconazole is (40 to 10):(20 to 5); and in addition, the bactericide is characterized by obvious sterilization effect, quick effectiveness of drug properties, long duration of drug action and no residues compared with conventional bactericides by adopting the technical scheme.
Description
Technical field
The present invention relates to the pesticide sterilizing field, specifically, relate to a kind of bactericide of preventing and treating alternaria leaf spot of apple.
Background technology
Advocating today green and the protection environment, multiple high poison and high residue chemicals are limited the quantity of or are stopped production.According to investigations, the whole world pathogenic microorganism (fungi, strong bacterium, rickettsia, mycoplasma, virus, algae etc.) harmful to plant has more than 80,000 kinds.Plant disease brings about great losses to agricultural, and global crops reduce the about 500Mt of output thus every year on average.Serious famine once repeatedly took place to cause because of certain plant disease is popular in history, even a large amount of populations calamity hungry to death.Using bactericide is a kind of cost-effective method of controlling plant diseases.Organic mercury, organo-arsenic and some organochlorine bactericide gradually are eliminated because of toxicity or problem of environmental pollution.The systemics of a new generation further enlarges the market of bactericide owing to control efficiency improves.
Common in the crop spot defoliation have an alternaria leaf spot of apple, and the alternaria leaf spot of apple apple leaf sheet of at first mainly causing harm is that new red magnitude marshal is the important disease of apple; Secondly, cause the apple early leaf fall, cause that tree vigo(u)r is weak, fruit output and quality reduce, and storage period is also infected other germs easily, causes rotten.During wet weather, sick portion positive and negative all can grow blackish green to black mustiness thing, i.e. conidiophore of germ and conidium.
At present, be chemical control to the main control of alternaria leaf spot of apple, lay special stress on protecting early stage blade, be based on preventing.But but medicament commonly used have safe and sound life 70% wetting powder, 70% mancozeb wet-milling, 10% Polyoxin wet-milling, 50% iprodione wettable powder, 80% give birth to greatly (mancozeb) but wet-milling, 90% 3 second aluminium phosphate, 50% iprodione wettable powder and 12.5% tebuconazole suspension concentrates.
But above-mentioned medicament has many shortcomings when control:
1, bactericidal effect is not obvious;
2, spraying the back property of medicine takes effect slowly;
The duration of spraying the back drug effect is short.
Summary of the invention
The technical problem that the present invention will solve is to overcome above-mentioned defective, provide a kind of bactericidal effect obviously, the bactericide of the long control alternaria leaf spot of apple of instant effect, duration of efficacy.
For addressing the above problem, the technical scheme that the present invention adopted is:
A kind of bactericide of preventing and treating alternaria leaf spot of apple is characterized in that the composition of said bactericide comprises iprodione and Tebuconazole, and the percentage by weight of said iprodione and Tebuconazole is (40 ~ 10): (20 ~ 5).
As a kind of improvement:
The percentage by weight of said iprodione and Tebuconazole is 20:10.
As further improvement:
The percentage by weight of said iprodione and Tebuconazole is 30:15.
As further improving again:
The percentage by weight of said iprodione and Tebuconazole is 40:20.
As further improving again:
The percentage by weight of said iprodione and Tebuconazole is 10:5.
As further improving again:
The percentage by weight of said iprodione and Tebuconazole is 30:10.
As further improving again:
The auxiliary agent of said bactericide is an emulsifier ABSCa, and the continuous phase of said bactericide is water.
Said ABSCa accounts for 10～20% of bactericide gross weight.
Iprodione is dicarboximide class high-efficiency broad spectrum, contact killing type bactericide, is applicable to diseases such as crop early defoliation disease, gray mold, early blight such as the multiple fruit tree of control, vegetables, melon and fruit class, other title iprodione or Sang Dien.The mechanism of action of iprodione: iprodione can CKIs kinases, control signal in the cell of many cell functions, comprise that carbohydrate combines to get into the interference effect of fungal cell's component.Therefore; It both can suppress the sprouting and the generation of fungal spore, also can suppress mycelial growth, and was promptly all influential to pathogen each developmental stage in the history of life; Spore, mycelium, sclerotium are worked simultaneously; Suppress germ spore germination and mycelial growth, porous hardly in plant corpus belongs to protective fungicide.This medicament has bactericidal action preferably to Botrytis cinerea genus, nuclear disk genus, neurospora, bulbil genus, clump stalk spore accessory.
Tebuconazole is a kind of efficient, wide spectrum, interior absorption triazole bactericidal agent, has protection, treats, roots out three big functions, and fungicidal spectrum is wide, the lasting period is long.These article are used to prevent and treat stalk break, and not only preventive effect is good, and have characteristics such as resistant to lodging, that production-increasing function is obvious.Mechanism of action to germ is the demethylation that suppresses ergosterol on its cell membrane, makes germ can't form cell membrane, thus kill pathogens.
The chemical name of ABSCa is a calcium dodecyl benzene sulfonate, is undertaken after alkylated reaction becomes detergent alkylate by polypropylene tetramer and benzene, and through sulfonation with the calcium hydroxide neutralization and get, solid is slightly soluble in water, is the emulsifier of preparing agricultural chemicals again.
Iprodione and Tebuconazole by the bactericide of must mixed processing, are utilized both different sterilization mechanisms, learn from other's strong points to offset one's weaknesses separately; Not only do not have to reduce the property of medicine separately, and guaranteeing that using medicine all is under the prerequisite of low toxicity, gets into crop inside fast and sets about killing pathogenic bacteria from mechanism of different; And can form layer protecting film in crop surface, and make germ be difficult to invade, duration of efficacy is long; Thereby play cover crop, killing pathogenic bacteria, the effect of increasing both production and income.
In use, get this bactericide, after the dilution proportion of water with 1:5000 ~ 6000; Crops are sprayed prevent and treat disease; Behind germ contact medicament, the iprodione in the medicament suppresses germ spore germination and mycelial growth, and Tebuconazole then suppresses the demethylation of ergosterol on its cell membrane; Make germ can't form cell membrane, thus kill pathogens.
Owing to adopted technique scheme, the present invention compares with existing bactericide and has the following advantages:
1. bactericidal effect is obvious, and the spot defoliation of control apple has good effect;
2. spray back property of medicine instant effect;
3. longer duration behind the spray medicine is long to the crop protection phase;
4. noresidue, the composition that people and animals is not harmful to.
Below in conjunction with embodiment the present invention is further specified.
