Abstract
The invention relates to an agricultural bactericidal agent, especially relating to an agricultural bactericidal agent prepared with extract of psoralen to prevent rice blast for rice, late blight for tomato and potato, chilli epidemic disease and gray mold for cucumber and so on. The total extract of psoralen can be got by chemical extracting method, for example, extracting with ethanol of 95%, or methanol or water or organic solvent from psoralen seed powder, then condensing and getting the total extract. Dissolving the total extract in water or acetone or dimethyl sulfoxide or organic solvent to prepare mother liquid. The bactericidal agent is characterized by high efficiency, low toxicity and residual and hard for drug resistance.
Description
Technical field
The present invention relates to a kind of botanical disinfectant use in agriculture, particularly relate to a kind of extract of Psoralea corylifolia that utilizes and be used to prevent and treat the botanical disinfectant use in agriculture of multiple frequently seen plants diseases such as rice blast, tomato late blight, potato late blight, Phytophthora capsici disease, cucumber grey mold.
Background technology
Rice blast (Blast Fungus), it is one of the most serious rice disease of rice district, whole world harm, this disease all can work the mischief to paddy rice throughout the year, and its harm spreads all over each position of paddy rice, and seedling rice blast, leaf pest, pulvinus pest, joint rice blast, panicle blast, branch stalk pest and grain pest etc. are arranged.Generally cause the paddy rice underproduction 10%~20%.With China is example, and since the nineties in 20th century, all more than 3,800,000 hm2, year loss paddy reaches several hundred million kilograms to the year generation area of this disease.
Tomato late blight is a kind of destructive world vegetable disease, and countries such as the U.S., Canada, Mexico, France, Switzerland, Australia all report this disease serious harm.Provinces and cities' late blights such as China Beijing, Shanxi, Yunnan, Guizhou, Shandong, Shaanxi, Henan, Hebei generally take place.Tomato late blight was broken out in Kunming, 1990~1994 years Yunnan in 5 years altogether 3 times, and each incidence of disease all reaches 100%.In recent years along with cropping system transforms (turning to open country, spring, autumn, the plantation throughout the year of winter protection ground intersection from single spring sowing open country plantation of past) fast, tomato late blight has become the anniversary disease of frequent generation.
At present, the utilization of resistant variety and the use of chemical pesticide are still the effective measure of controlling plant diseases, but because of the unification of resistant variety, the complexity of phytopathogen biological strain heredity and pathogenic diversity and the toxicity of chemical pesticide and the pesticide resistance of pathogen, resistant variety and chemical pesticide use on producing and all are subjected to certain restriction, for this reason, the biological control of plant diseases such as rice blast, tomato late blight, potato late blight, Phytophthora capsici disease particularly the research and development of biopesticide be the needs of sustainable development of agricultural production.Botanical pesticide best embodies the characteristics of biological control, and is less to the selection pressure of environment, and is difficult for making the target bacterium to develop immunity to drugs, and therefore, the research of botanical pesticide and application will provide the approach of safer controlling plant diseases more efficiently for people.
Summary of the invention
The objective of the invention is to: in frequently seen plants, filter out the target plant that plant diseases such as rice blast, tomato late blight, potato late blight, Phytophthora capsici disease, gray mold of cucumber, cucumber anthracnose are had certain control efficiency, thereby develop botanical biological pesticide.
The objective of the invention is to be achieved through the following technical solutions:
A kind of botanical disinfectant use in agriculture of the present invention, be to utilize the total extract of Psoralea corylifolia to come controlling plant diseases, comprise multiple frequently seen plants diseases such as control rice blast, tomato late blight, potato late blight, Phytophthora capsici disease, gray mold of cucumber, cucumber anthracnose.
A kind of botanical disinfectant use in agriculture of the present invention, be that the malaytea scurfpea fruit total extract can obtain from Psoralea corylifolia with the chemical extraction method, as using Psoralea corylifolia seed powder, ethanol with 95% or methyl alcohol or water or other organic solvent extraction, and behind concentrating under reduced pressure, obtain total extract, after being melted, total extract water or acetone or dimethyl sulfoxide (DMSO) or other organic solvent be made into certain density mother liquor.
Advantage of the present invention and effect are:
1. the total extract of Psoralea corylifolia has the obvious suppression effect through the lab screening evidence to plant diseases such as rice blast, tomato late blight, potato late blight, Phytophthora capsici disease, gray mold of cucumber, cucumber anthracnoses.Simultaneously, have efficient, low toxicity, low-residual, characteristics such as be difficult for developing immunity to drugs.
2. the Psoralea corylifolia used of the present invention, all there are certain bacteriostatic activity, particularly seed in its each position.
3. Psoralea corylifolia (Fructus Psoraleae) is a leguminous plant, and hillside, small stream limit, limit, field are born in main product Sichuan, Henan, Shaanxi, Anhui, and the vegetable material source is abundant, is easy to get.Aspect controlling plant diseases, have wide application and DEVELOPMENT PROSPECT, help the sustainable development of world agriculture.
Embodiment
Part embodiment of the present invention is listed below:
Embodiment 1

Embodiment 3
With the total extract dmso solution, getting 1 part of solution joins in the culture plate, add 80 parts of culture fluids containing spore again, mixing (total extract concentration mass volume ratio 200mg/l), with the culture fluid that contains 1: 80 dimethyl sulfoxide (DMSO) with not solvent-ladenly be treated to contrast, put into incubator after the processing and cultivate, wait to contrast abundant sprouting after, in test under microscope spore germination and mycelial growth situation.
The malaytea scurfpea fruit total extract under mass volume ratio 200mg/l concentration to the inhibitory action such as the following table of several frequently seen plants pathogen spore germination:
The Psoralea corylifolia crude extract | The paddy rice rice blast | The tomato late blight | Phytophthora capsici | The cucumber grey mold | The cucumber anthrax |
Germination rate (%) | 92 | 95 | 100 | 90 | 95 |
Inhibiting rate (%) | 100 | 100 | 100 | 60 | 30 |
Claims (2)
