According to the method, the prevention and control steps are simple, the design is reasonable, efficient and safe, the implementation performance is high, the prevention and control efficiency is high, the result repeatability is good, the yield per unit of crops and the income of farmers can be increased under the condition of not increasing prevention and control cost, the technical applicable range is wide, and the economic and ecological benefits are remarkable.
Description
Technical field
The invention belongs to viral diseases of plants Control Technology field, and in particular to a kind of field thrips and tomato spotted wilf viruses
The preventing control method of category disease.
Background technology
Tospovirus（Tospovirus）Belong to bunyaviridae（Bunyaviridae）.Bunyaviridae
There are 5 category.Tospovirus virus is unique virus for contaminating plant in the section.The main virus mediator that passes is thrips
（Thrips）.Tospovirus virus disease extensively occurs in worldwide, and Tospovirus virus can soak
Dye diversified economy crop is such as：Fructus Lycopersici esculenti, Fructus Capsici, Rhizoma Solani tuber osi, Nicotiana tabacum L., silkworm and mulberry, Fructus actinidiae chinensiss, Semen sojae atricolor, Semen arachidis hypogaeae etc., the outburst of the virus with
Prevalence brings CR Critical loss to crop production.It is mainly single use chemical agent prevention and control to the prevention and control of the disease at present to pass
Virus mediator thrips, easily cause agriculture it is residual exceeded and also easily cause thrips Drug resistance enhancing, be food safety and ecological environment
Potential threat.In consideration of it, therefore, exploitation is a kind of from Synthetical prevention angle, set up a kind of efficient stable prevention and control thrips and
The method of its Tospovirus virus disease propagated is very important.
The content of the invention
It is an object of the invention to provide the preventing control method of a kind of field thrips and Tospovirus disease.
The object of the present invention is achieved like this, including disease prevention and control, prosperous long initial stage disease after selection of land, pretreatment, transplanting
The steps such as prevention and control, results, specifically include：
A, selection of land：Field of the Virus carried rate of crop rotation field, field crops and weeds less than 2.5 ‰ is selected, for Virus carried rate
Field higher than 2.5 ‰ sprays insecticide and diseases prevention medicament by removing the malicious host of doubtful band so that field host is with malicious rate
Less than 2.5 ‰；
B, pretreatment：Including field pretreatment and plantling pretreatment, field pretreatment is killed including field thrips and posted with virus
Main removing, plantling pretreatment is that worm and Viral diagnosis are carried out to plantling, is selected nontoxic without worm tobacco seedlings, spray on plants resistance
Transplanted after derivant；
Disease prevention and control after C, transplanting：2 ~ 4 days after transplanting, spray on plants resistance inductors are strengthening disease resistance of plant；
D, prosperous long initial stage disease prevention and control：Blue insect-sticking plate is hung up in field, per mu hangs up 3 ~ 5, according to thrips population dynamic
Insecticide or release Predatory Mites or sprinkling muscardine are sprayed in time；It was found that there is spotted wilt diseased plant, eliminate remove in time, and spray on plants
Resistance inductors are strengthening disease resistance of plant；
E, results：Harvested immediately after maturation.
The present invention can effectively prevent and treat the Tospovirus disease for passing malicious thrips and its propagation, and Synthetical prevention effect is reachable
76.3% ~ 84.3%.Prevention and control step of the present invention is simple, reasonable in design, highly effective and safe, and exploitativeness is strong, prevention and control efficiency high, as a result
It is reproducible, crop yield can be improved in the case where prevention and control cost is not increased, is increased farmers' income, technology is applied widely,
Economic benefit and ecological benefits are notable.
Specific embodiment
With reference to case study on implementation, the present invention is further illustrated, but never in any form to the present invention limited
System, based on present invention teach that any conversion for being made or replacement, belong to protection scope of the present invention.
Field thrips of the present invention and the preventing control method of Tospovirus disease, including selection of land, pretreatment, shifting
The step such as disease prevention and control, prosperous long initial stage disease prevention and control, results, specifically includes after cultivation：
A, selection of land：Field of the Virus carried rate of crop rotation field, field crops and weeds less than 2.5 ‰ is selected, for Virus carried rate
Field higher than 2.5 ‰ sprays insecticide and diseases prevention medicament by removing the malicious host of doubtful band so that field host is with malicious rate
Less than 2.5 ‰；
B, pretreatment：Including field pretreatment and plantling pretreatment, field pretreatment is killed including field thrips and posted with virus
Main removing, plantling pretreatment is that worm and Viral diagnosis are carried out to plantling, selects nontoxic without worm tobacco seedlings, sprays AHO5000
Times liquid or 3% super quick 3000-5000 times of liquid of protein particle agent or 8% 1200-1600 times of liquid of Ningnanmycin water preparation or 2% amino-oligosacchride

Disease prevention and control after C, transplanting：2 ~ 4 days after transplanting, AHO5000 times of liquid or 3% super quick 3000-5000 times of protein particle agent are sprayed
Liquid or 8% 1200-1600 times of liquid of Ningnanmycin water preparation or 2% 1000-1200 times of liquid of amino-oligosaccharide water preparation or 0.5% lentinan
The plant resistance to environment stress derivants such as 300-500 times of liquid of water preparation are strengthening disease resistance of plant；
D, prosperous long initial stage disease prevention and control：Blue insect-sticking plate is hung up in field, per mu hangs up 3 ~ 5, according to thrips population dynamic
Insecticide or release Predatory Mites or sprinkling muscardine are sprayed in time；It was found that there is spotted wilt diseased plant, eliminate remove in time, and spray
AHO5000 times of liquid or 3% super quick 3000-5000 times of liquid of protein particle agent or 8% 1200-1600 times of liquid of Ningnanmycin water preparation or 2% ammonia
The plant resistance to environment stress derivant such as 1000-1200 times of liquid of base oligosaccharide water preparation or 0.5% 300-500 times of liquid of lentinan water preparation is strengthening
Disease resistance of plant；
E, results：Harvested immediately after maturation.
Carry out to plantling worm and Viral diagnosis described in step B is to carry out inspection sampling observation, observation of plant to plantling
Thrips is whether there is on seedling leaf, and is inspected by random samples by the 3 ~ 5% of plantling total amount, detection band poison rate, recall rate is less than the 2 ‰ of sampling observation quantity
Can be transplanted.
