Description
Technical field
The present invention relates to the pesticide sterilizing field, specifically, relate to a kind of bactericide of preventing and treating graw mold of tomato.
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.
Graw mold of tomato is a kind of fungal disease of the common and difficult control of open country, protection ground crop, belongs to low temperature and high relative humidity type disease, and the pathogen growth temperature is 2～30 ℃, and it is the disease high-incidence season when above that 20～25 ℃ of temperature, humidity continue 90%.Due to gray mold is infected by the Botrytis cinerea bacterium, belong to fungal disease, flower, really, leaf, stem all can fall ill.Fruit is caught an illness, and Chinese olive is injured heavily, and residual column cap or petal are many to be infected earlier; The back causes pericarp to be canescence to the fruit expansion, and the mould layer of thick grey is arranged; Be the rotten shape of water, the blade morbidity begins from blade tip, along becoming " V " shape inwardly to expand between vein; Taupe, limit have the alternate line shape line of the depth, sick strong the boundary clearly.This disease is a kind of typical aeroborne disease, can propagate with air, current and farming operation.In actual disease control process, be difficult to adopt an effective measure and thoroughly cut off source of infection; Under the situation that pathogen is invaded, also be difficult to utterly destroy pathogen, spray like medicament, be difficult to solve the pathogen in air and the dew; And smoked separately canopy can not solve on the invalid bodies such as disease leaf, sick fruit or inner pathogen by emphasis.
At present, the bactericide of control graw mold of tomato mainly contains: 30% phonetic mould thiram wettable powder, 40% phonetic mould amine suspending agent, 50% iprodione wettable powder and 50% procymidone wetting powder.But there are many shortcomings in the above-mentioned medicament that carries out when control:
1, bactericidal effect is not obvious;
2, after the sprinkling, the property of medicine takes effect slowly;
Duration of efficacy 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 graw mold of tomato of instant effect and 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 graw mold of tomato is characterized in that the composition of said bactericide comprises iprodione and procymidone, and the percentage by weight of said iprodione and procymidone is (20 ~ 5): (35 ~ 10).
As a kind of improvement:
The percentage by weight of said iprodione and procymidone is 10:25.
As further improvement:
The percentage by weight of said iprodione and procymidone is 5:35.
As further improving again:
The percentage by weight of said iprodione and procymidone is 5:10.
As further improving again:
The percentage by weight of said iprodione and procymidone is 10:30.
As further improving again:
The percentage by weight of said iprodione and procymidone is 20:25.
As further improving again:
The percentage by weight of said iprodione and procymidone is 20:10.
As further improving again:
The percentage by weight of said iprodione and procymidone is 20:35.
As further improving again:
The auxiliary agent of said bactericide is an emulsifier ABSCa, and continuous phase is water.
Said auxiliary agent A BSCa 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.Iprodione gets mechanism of action: 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.
Procymidone is interior absorption fungicide, and Botrytis and Sclerotinia fungi are had special efficacy, can prevent and treat the gray mold, stalk break of fruit tree, vegetable crop etc., and the fungi that benzimidazole is produced resistance is also effective.Protection is effective after using, the lasting period is long, can stop the scab developmenting spread.Use at crop premorbid or their early stage, can obtain promising result.Protective effect to crop is outstanding, and the lasting period is long, can effectively stop the development of scab.Protectiveness is used or use all can obtain promising result at the initial stage of a disease regardless of carrying out at premorbid.Can absorb rapidly through leaf and the root of crop after the sprinkling, therefore, also can not controlled even if directly be sprayed onto the disease of medicament part, also effective to the germ that invades deep in the plant corpus.The rain fastness of procymidone is good, and is different fully with benzimidazole medicament sterilization mechanism commonly used, therefore under the situation of benzimidazole effect of chemical control difference, uses procymidone still can obtain satisfied control efficiency.
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 procymidone are mixed and made into bactericide in proportion, utilize both different sterilization mechanisms, make the two can be complementary aspect sterilization; Learn from other's strong points to offset one's weaknesses, 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 1:2000; Crops are sprayed prevent and treat disease; Behind germ contact medicament, the iprodione in the medicament suppresses germ spore germination and mycelial growth, and procymidone can absorb rapidly through leaf and the root of crop; Hinder the synthetic of germ mycelia top normal cell wall, thus kill pathogens.
Owing to adopted technique scheme, the present invention compares with existing agricultural chemicals and has the following advantages:
