Abstract
The invention discloses a bactericidal composition containing pyraclostrobin and procymidone. The bactericidal composition comprises active components of pyraclostrobin and procymidone in the weight ratio of 1:20-20:1, and the active components account for 5-60 wt.% of the composition. The bactericidal composition provided by the invention has high bactericidal activity, delays the emergence and development of pathogen resistance, reduces the control dosage in actual production, and has the advantages of economical performance, high efficiency, safety and environment-friendliness. The bactericidal composition can be applied to control of grape botrytis and pear black spot, and especially has substantial control effect on gray mold caused by Botrytis cinerea.
Description
Technical field
The present invention relates to disinfectant use in agriculture field, specifically the bactericidal composition of a kind of pyraclostrobin-containing and Sukeling.
Background technology
Gray mold is the common and a kind of fungal disease of more difficult control of open country, protecting field crop, and belong to low temperature and high relative humidity type disease, growth of pathogenic bacteria temperature is 20 ~ 30 DEG C, is the disease high-incidence season when temperature 20 ~ 25 DEG C, humidity continue more than 90%.Gray mold, caused by the pathogen of Botrytis cinerea infects, belongs to fungal disease, and flower, really, leaf, stem all can fall ill.The sick seedling look of gray mold is shallow, and the morbidity of blade, petiole is in canescence, and water stain shape, organization softening is to rotting, and during high humidity, there is grey mold on surface.Children's stem is many to come into being irregular water logging spot at petiole base, and very fast deliquescing is rotted, and hang contracting or folding fall, and last sick scutellum rot is withered dies of illness.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; When pathogen invades, be also difficult to utterly destroy pathogen, as medicament sprays, be difficult to solve the pathogen in air and dew; And smoke separately canopy, can not solve on the invalid body such as disease leaf, sick fruit or the pathogen of inside by emphasis.
Pyraclostrobin is a kind of methoxy acrylic bactericide, has protection, treatment, blade infiltration conduction.The mechanism of action is mitochondrial respiratory inhibitor, namely by stoping electro transfer in cytochrome synthesis.Pyraclostrobin missible oil, through field control effectiveness test result, shows there is good control efficiency to powdery mildew of cucumber, downy mildew and banana freckle, leaf spot, stalk break etc.
Chemical name: N-[2-[[1-(4-chlorphenyl) pyrazole-3-yl] oxygen methyl] phenyl]-N-methoxy carbamate methyl esters
Structural formula is as follows:
Sukeling, also known as procymidone, is a kind of dicarboximide class low toxicity bactericide, and have protection, treatment double action, use safety, the lasting period is longer.This medicine both can not be subject to infection process by cover crop, can kill again the germ having invaded plant corpus inside, and effectively can stop Spot expansion.Therefore, carry out protectiveness use or carry out therapeutic at the initial stage of a disease using and all can obtaining and be satisfied with control efficiency at premorbid.Use optimum period, is long, and systemic action is given prominence to, resistance of rainwater washing against; The disease not directly being sprayed onto medicament part also can be controlled.Structural formula is as follows:
Summary of the invention
The invention provides the bactericidal composition of a kind of pyraclostrobin-containing and Sukeling, there is bactericidal activity high, delay pathogen pesticide resistance emergence and development, and dosage total in unit are is declined, economic, efficient, environmental protection, have special efficacy preventing and treating in gray mold.
Two classes are had the bactericide of different mechanism of action by the present invention, namely methoxy acrylic bactericide pyraclostrobin and dicarboximide fungicide Sukeling combined, and be processed into the upper easy-to-use preparation of production, be used alone in two kinds of compositions and compare, there is biologically active high, dosage total in unit are declines, greatly reduce dispenser cost, delaying pathogen pesticide resistance emergence and development to a greater extent simultaneously, reduce disease fungus produces resistance risk to single bactericide, extend the service life of each component in bactericidal composition, thus realize economical, efficiently, the goal of the invention of environmental protection.
Technical scheme of the present invention is:
The bactericidal composition of a kind of pyraclostrobin-containing and Sukeling, it is characterized in that, the active component of described bactericidal composition is pyraclostrobin and Sukeling, and the mass ratio of pyraclostrobin and Sukeling is 1:20 to 20:1, and in composition, active component mass percentage is 5-60%.
Described pyraclostrobin-containing and the bactericidal composition of Sukeling, is characterized in that: described active component pyraclostrobin and the mass ratio of Sukeling are 1:10 to 10:1.
Described pyraclostrobin-containing and the bactericidal composition of Sukeling, is characterized in that: described pyraclostrobin and the mass ratio of Sukeling are 1:3-8.
Described pyraclostrobin-containing and the bactericidal composition of Sukeling, is characterized in that: described pyraclostrobin and the mass ratio of Sukeling are 1:4-6.
Described pyraclostrobin-containing and the bactericidal composition of Sukeling, is characterized in that: the formulation of described bactericidal composition is suspending agent or missible oil.
Described pyraclostrobin-containing and the bactericidal composition of Sukeling are applied on control grape grey mould and Pear black spot.
Remarkable result of the present invention and advantage are:
The present invention has higher control efficiency to grey mold disease, there is notable synergistic effect between two components; Part high price pesticide species can be replaced, and reduce dosage, effectively reduce ecological disruption and environmental pollution, and the fruit yield and quality such as grape, peach can be improved; In the present invention, pyraclostrobin and Sukeling all belong to the toxicity such as low, and to people and animals, beneficial organism, Environmental security; The pesticide resistance of germ to single medicament can be delayed.
First the EC of pyraclostrobin and Sukeling two single compound (hereinafter referred to as medicament) is measured
50(drug safety index), according to the EC of two single medicaments
50set the portfolio ratio of two medicaments by Wadley method, and according to Wadley coefficient of synergism C value, determine suitable composition ratio, then verified by the abundant method of Sun Yun.
Test objective thing is ash arrhizus bacteria, but does not limit so.Test adopts mycelial growth determination method, makes pastille medium by different disposal, and each process 4 repetitions, connect bacterium after 3 days, investigate the growth inhibitory effect of each process to ash arrhizus bacteria.By the linear regression analysis between the probit value of preventive effect and the logarithm value of serial drug concentration, obtain the EC50 of each medicament, calculate coefficient of synergism (SR) according to Wadley method, and make overall merit accordingly.SR≤0.5 represents to have antagonism, and 0.5 < SR < 1.5 represents to have summation action, and SR >=1.5 are synergistic effect.SR value calculating method is as follows:
EC
50(theoretical value)=(a+b)/(a/EC
50A+ b/EC
50B)
SR=EC
50(theoretical value)/EC
50(real value)
SR≤0.5, then two kinds of medicament mixtures have antagonistic action
SR=0.5 ~ 1.5, then two kinds of medicament mixtures have addition
SR >=1.5, then two kinds of medicament mixtures have synergistic effect
Table 1 pyraclostrobin and Sukeling composition are to the Wadley method measurement result of gray mold
Note: S is Sukeling, and B is pyraclostrobin.
Can analyze from above data, pyraclostrobin and the fungistatic effect of Sukeling composition to ash arrhizus bacteria of different proportion are different, on the whole, its ratio has synergy or addition in the scope of 1:20 to 20:1, and wherein maximum enhancing proportions is the proportioning of pyraclostrobin and Sukeling is 5:1.
Below in conjunction with embodiment, the invention will be further described, but be not limited thereto.
