Abstract
The plant bactericide for preventing and treating crop's diseases consists of Salvia sclarea flower extractive and assistant, and is prepared into oil emulsion, dense emulsion or microemulsion via traditional process. In the preparation, Salvia sclarea flower extractive with sclareol as effective component accounts for 0.1-80.0 wt% and the assistant accounts for 20.0-99.9 wt%. Compared with available technology, the plant bactericide of the present invention has high preventing and treating effect, environmental safety, less resistance and other advantages.
Description
Technical field: the present invention relates to a kind of bactericide that is used to prevent and treat corps diseases, belong to the field of pesticide technology.
Background technology: the crop loss that whole world every year causes because of plant disease is up to more than 12%.In China, corps diseases relies on the chemosynthesis bactericidal agent for preventing and treating always, because long-term unreasonable use has not only produced serious pesticide resistance, and posed a big pressure to environmental quality.Therefore all enjoy attention in the biological research and development of bactericide, particularly bactericide rationally of development both at home and abroad, but big breakthrough is not arranged so far, the bactericide product of China's exploitation is very few.
Bailey, J.A. wait report (Nature once, Vol.255:328～329,1975), from shepherd's purse grass platymiscium (Wicotianaglutinosa) leaf, extract the sclareol that separates and 13-epi-sclareol and give birth in the survey soybean rust and wheat leaf become rusty at stripped (25 μ g/ml) and live body (100 μ g/ml) tangible bacteriostatic activity is arranged, but under 500 μ g/ml concentration to also non-activity of wheat powdery mildew.Also there is the sclareol compounds in Salvia sclarea (Salvia sclarea) in spending, and mainly as the raw material of synthetic perfume, not having so far with the sclareol both at home and abroad is the bactericide product of active ingredient.
Summary of the invention: the object of the present invention is to provide a kind of bactericide, not only control efficiency is good, and environmentally safe.
Bactericide of the present invention mainly is made up of the extract and the auxiliary agent that with the sclareol are the Salvia sclarea flower of active ingredient.The shared mass percent of each component of this bactericide is as follows:
The Salvia sclarea flower extract 0.1～80.0% that contains sclareol
Auxiliary agent 99.9～20.0%
This bactericide of the present invention can be processed into missible oil, emulsifiable concentrate, microemulsion by conventional method.
The composition (mass percent) of Salvia sclarea sterilization missible oil
The Salvia sclarea flower extract 0.1～80.0% that contains sclareol
Emulsifier 0.1～10.0%
Solvent 99.8～10.0%
The composition (mass percent) of Salvia sclarea sterilization emulsifiable concentrate
The Salvia sclarea flower extract 0.1～40.0% that contains sclareol
Emulsifier 0.2～20.0%
Antifreeze 2.0～10.0%
Water 97.7～30.0%
The composition of Salvia sclarea bactericidal microemulsion (mass percent)
The Salvia sclarea flower extract 0.1～20.0% that contains sclareol
Emulsifier 0.2～20.0%
Antifreeze 2.0～10.0%
Water 97.7～50.0%
Compared with prior art, bactericide of the present invention has the following advantages:
1. control efficiency is good.Potted plant control wheat powdery mildew is at 100mg.L
-1During concentration, its protection effect is 94.94%, and result of treatment is 84.21%, and recommends both at home and abroad at present to be used to prevent and treat the triazole bactericidal agent propiconazole of wheat powdery mildew at 125mg.L
-1During concentration, its protection effect is 72.2%, and result of treatment is 65.33%.The explanation of control in field graw mold of tomato result of the test, 500 times of 10% Salvia sclarea missible oil dilutions, preventive effect is 88.7%, and 1500 times of preventive effects of 50% Sukeling wettable powder dilution agent are 76.4%.
2. the present invention is a bactericide, is easy to decompose in environment, and pathogen is difficult for developing immunity to drugs.Toxicity Determination result
With botrytis cinerea (Botrytis cintrea) serves as for the examination bacterium, adopts and suppresses the virulence that the mycelial growth rate method has been measured the Salvia sclarea flower extract, and its virulence equation is y=2.1520+1.5087x, 50% effective concentration (EC
50) be 77.20mg.L
-1Results from pot experiment test:
Measured of protective effect and the therapeutic action of Salvia sclarea flower extract with pot-culture method to wheat powdery mildew.With 100mg.L
-1The Salvia sclarea flower extract spraying of concentration, its protection effect is 94.94%, result of treatment is 84.21%.Record propiconazole at 125mg.L under the same terms
-1During concentration, its protection effect is 72.2%, and result of treatment is 65.33%.The field medicine effect test result:
The control in field graw mold of tomato is tested in May, 2002 and is carried out in Yang Ling demonstration area, Shaanxi Province.Respectively at May 11,15 days spraying control twice, investigation on May 20 preventive effect.The result shows that 500 times (concentration is 200 mg.L to the dilution of 10% Salvia sclarea missible oil
-1) time preventive effect be that 1500 times (concentration is 333 mg.L to 88.7%, 50% Sukeling wettable powder dilution agent
-1) time preventive effect be 76.4%.
Embodiment:
1. the Salvia sclarea dried flower is dropped into extractor, add industrial benzinum and carry out refluxing extraction, obtain the Salvia sclarea extract;
