Abstract
The present invention relates to cultural control field, and in particular to high-tenacity pesticide, to current capsicum epidemic disease germ strong toxicity, easy the problem of making a variation, discloses a kind of high-tenacity pesticide.The pesticide is made of metalaxyl and polyvinyl alcohol, and the volume ratio of wherein metalaxyl and polyvinyl alcohol is（15‑60）：1, by that by after polyvinyl alcohol and metalaxyl combination, a kind of high-tenacity pesticide can be obtained, effectively kill capsicum epidemic disease germ.
Description
Technical field
The present invention relates to cultural control field, and in particular to high-tenacity pesticide.
Background technology
Capsicum scientific name:Capsicum annuum L., Solanaceae, Capsicum.For 1 year or limited herbaceos perennial.Fruit
It is real, in green during prematurity, to become cerise, green or purple after ripe usually in cone or oval, with it is red the most
It is common.The fruit of capsicum has pungent because pericarp contains capsaicine, can improve a poor appetite.Ascorbic content is in vegetables in capsicum
It is middle to occupy first, Mexico is originated in, is passed to China at the end of the Ming Dynasty.
Capsicum epidemic disease is the destructive disease in pepper planting, is generally occurred in China, usual dead plant rate more than 30%,
90% can be reached under serious situation.The germ of capsicum epidemic disease be epidemic disease bacterium egg spore overwintering in soil move about intrusion host,
So that pepper plant is diseased.
Capsicum epidemic disease germ has soil and the dual propagating characteristic of air, therefore its prevention and control is more difficult, and capsicum epidemic disease germ
Itself there is higher variability, easily develop immunity to drugs to pesticide.
The content of the invention
The problem of present invention is for current capsicum epidemic disease germ strong toxicity, easily variation, discloses a kind of high-tenacity pesticide.Should
Pesticide is made of metalaxyl and polyvinyl alcohol, and the volume ratio of wherein metalaxyl and polyvinyl alcohol is（15-60）：1.
Preferably, the volume ratio of metalaxyl and polyvinyl alcohol is 15:1.
Alternatively, the volume ratio of metalaxyl and polyvinyl alcohol is 20:1.
Alternatively, the volume ratio of metalaxyl and polyvinyl alcohol is 40:1.
Or, it is preferable that the volume ratio of metalaxyl and polyvinyl alcohol is 60:1.
Wherein most preferably, the volume ratio of metalaxyl and polyvinyl alcohol is 20:1.
Metalaxyl is also known as metalaxyl, has very strong virulence for capsicum epidemic disease germ, but metalaxyl easily produces
The resistance to the action of a drug.
Polyvinyl alcohol is a kind of organic compound, general white sheet, cotton-shaped or pulverulent solids, tasteless.It is dissolved in
Water, is slightly soluble in dimethyl sulfoxide (DMSO).Polyethylene is currently used as manufacture Pioloform, polyvinyl acetal pipe as a kind of important industrial chemicals
Road, vinylon synthetic fibers, fabric-treating agent, emulsifying agent, paper coating, adhesive, glue etc..
Polyvinyl alcohol and metalaxyl are combined at present, not yet had been reported that to reduce the drug-fast application of metalaxyl.
The present inventor is found surprisingly that the addition of polyvinyl alcohol can significantly reduce capsicum epidemic disease germ in once testing
For the resistance to the action of a drug of metalaxyl, so that by after polyvinyl alcohol and metalaxyl combination, a kind of high-tenacity pesticide can be obtained, is effectively killed
Go out capsicum epidemic disease germ.
Embodiment
In order to be better understood from the present invention, below we in conjunction with specific embodiments to the present invention further explained
State.
Embodiment 1
Material：First by metalaxyl（It is purchased from Jiangsu Province Nantong Ran Hua factories）500 times of dilution, is made metalaxyl solution.Polyvinyl alcohol
（It is purchased from Nanjing Bo Jiang Chemical Co., Ltd.s）1000 times of dilution.
Then medicament is mixed to form according to the composition proportion in table 1 respectively.
Table 1：
| Metalaxyl（V/mL） | Polyvinyl alcohol（V/mL） | |
| No.1 medicament | 1500 | 100 |
| No. two medicaments | 2000 | 100 |
| No. three medicaments | 4000 | 100 |
| No. four medicaments | 6000 | 100 |
The preparation of Hot Pepper Seedling：Pepper seed is seeded in flowerpot in greenhouse, plastic nutrition bowl is transferred to after 2 leaf true leaf expansion
It is interior, it is used to during plant to be planted length to 4-5 piece blades test.
Preventive and therapeutic effect：No.1 medicament, No. two medicaments, No. three medicaments, No. four medicaments are uniformly sprayed on pepper seedling respectively,
Liquid of being subject to does not drip, and sprays water as control.40-50 plants of each chemicals treatment, and reprocess three times.Second after spray
It carries out germ inoculation by the following method.
Capsicum epidemic disease germ is inoculated with：It is 5000-10000 zoospore/mL spore suspensions as connecing bacterium solution using concentration.
Connect bacterium and use spray-on process, to Hot Pepper Seedling connect bacterium with the bacterium solution that connects prepared, when spraying ensures uniform as far as possible, and connecing bacterium amount is about
1-2ml suspension/strain, connect moisturizing 24 after bacterium it is small when, Routine Management in greenhouse（20-30℃）, connect investigation morbidity in second day after bacterium
Strain number, until morbidity stabilization is stopped.
Results and discussion：The inhibitory action that one to No. four medicament of measure sprouts phytophthora capsici sporangium, and calculate poison
Concentration in power regression equation and suppression, the results show that the EC of alone metalaxyl50For 9.9778 μ g/ml, the EC of medicament one50For
5.8325 μ g/ml, the EC of medicament two50For 4.1597 μ g/ml, the EC of medicament three50For 6.6726 μ g/ml, the EC of medicament four50For
7.2596μg/ml。
As a result illustrate, compared to metalaxyl, the medicament added with polyvinyl alcohol has stronger bactericidal effect, while result
Show the proportioning of medicament two, i.e. the volume ratio of metalaxyl and polyvinyl alcohol is 20:1 is optimal proportion.
Also, by being investigated to the incidence of capsicum epidemic disease after inoculation phytophthora capsici, we have observed that, metalaxyl-poly-
Vinyl alcohol can effectively realize the prevention effect to airborne capsicum epidemic disease, and alone compared to metalaxyl, and combination is poly-
Synergy is up to 30% after vinyl alcohol.
