Abstract
The invention relates to a biological agent for preventing the powdery mildew in pepper and the preparation method and the application thereof. The invention belongs to the technology field of biological pesticides. The agent is composed of raw egg yolk 19.5g, edible oil 1L and water 15kg. The preparation method includes: (a) taking the raw egg yolk 19.5g out and rinsing with the clear water for further use; (b) blending the egg yolk by the juice extractor, adding the edible oil 1L and blending the mixed liquid until the liquid is milk white; (c) adding the agent prepared in the method to the water 15kg and fully stirring the agent evenly. The prevention and cure effect can be achieved at more than 65% by spraying the agent on the pepper with the powdery mildew for three times. The agent has low-cost material, easy manufacture technology, good prevention effect, non-toxicity, harmlessness, non-environment pollution and good application prospect.
Description
Technical field:
The invention belongs to biological pesticide technical field, be specifically related to a kind of biologic product of preventing and treating pepper powdery mildew and its production and application.
Background technology:
Pepper powdery mildew is to be caused by Tartar's internal thread powdery mildew (Leveillula taurica (Lev.) Arn.), belongs to sac fungi, Erysiphales; No condition is that capsicum is intended the powder spore, belongs to imperfect fungus, hyphomycetales.This disease is a capsicum middle and later periods disease, has popular characteristics rapidly, and under the suitable situation of environmental condition, short-term can be able to be very popular, and is one of disease important during capsicum produces.
For a long time, pepper powdery mildew mainly relies on the chemical agent control, as triadimefon, carbendazim, sulphur colloidal suspension agent etc., cause disease to develop immunity to drugs, threaten the person poultry safety simultaneously, cause the increase of residue of pesticide, natural enemy is killed and wounded in a large number, microecological balance destroyed and environmental pollution in farmland does not meet the requirement that pollution-free vegetable produces.
Along with China joined WTO and people attention day by day to environmental and ecological protection; biological control is pollution-free with it; noresidue, no eco-toxicity and safety are good etc., and advantage plays leading role in the control of plant pest, greatly develops biopesticide China is had very important realistic meaning.Biopesticide is the important source of novel pesticide initiative, plays important effect in the biological control of plant pathogenic fungi disease.Biopesticide is easy to decompose to the person poultry safety,, is described as " nuisanceless " agricultural chemicals with environmentally compatible.Since the nineties, biopesticide has become one of focus of researching and developing in the agricultural biotechnologies industry from eighties of last century.
Summary of the invention:
The objective of the invention is provides a kind of biologic product of preventing and treating pepper powdery mildew and its production and application in order to address the above problem.
The present invention screens a kind of biologic product that pepper powdery mildew is had fine preventive and therapeutic effect from a plurality of prescriptions.(biologic product called after EGY of the present invention.) in existing bibliographical information, do not see to have and adopt egg yolk to be used for disease control with the oily prescription that mixes, particularly to the control of pepper powdery mildew.
Technical scheme provided by the invention is:
1, a kind of biologic product of preventing and treating pepper powdery mildew, form by following content and component:
Raw egg yolk 19.5g,
Edible oil 1L,
Water 15kg
2, the method for the above-mentioned preparation of preparation:
(1) prepares before the preparation; 1 of raw egg, edible oil, juice extractor.
(2) preparation process:
(a) take out raw egg yolk 19.5g, use the clear water rinsing, stand-by;
(b) with above-mentioned yolk juice extractor mixing, add the 1L edible oil, mixing to mixed liquor is a milky;
(c) preparation that method for preparing is obtained joins in the 15Kg water, stirs.
Above-mentioned steps is all carried out under normal temperature and normal pressure.
3, the application of above-mentioned preparation: with the preparation that method for preparing obtains, evenly be sprayed at the front and the back side of capsicum blade, spray area is 200m
2
Field control effectiveness test is the result show: the biologic product for preparing with said method to the control efficiency of pepper powdery mildew more than 65%.
Utilize the control to pepper powdery mildew of biologic product that the present invention produces, it is good to have control efficiency, nontoxic, harmless environmental protection, and cost of material is low, and the advantage that production technology is simple is easy to industrialization and commercialized development, has application promise in clinical practice.
Embodiment:
1, small plot experiment:
Totally 3 processing are respectively biologic product of the present invention (handling 1), positive control (handling 2), blank (handling 3), and every processing is established 3 and repeated, and each sub-district area is about 20m
2, test gross area 180m
2
Positive control: the pure and strong milk liquid of 5% own azoles (SC).
2, prepare used biologic product:
(1) prepares before the preparation; 1 of raw egg, edible oil, juice extractor.
(2) preparation process:
(a) take out raw egg yolk 19.5g, use the clear water rinsing, stand-by;
(b) with above-mentioned yolk juice extractor mixing, add the 1L edible oil, mixing to mixed liquor is a milky;
(c) preparation that method for preparing is obtained joins in the 15Kg water, stirs.
Above-mentioned steps is all carried out under normal temperature and normal pressure.
3, medicament usage amount:
(1) handle 1 (join biologic product): the above-mentioned biologic product that preparation is obtained get its 1/3, evenly be sprayed at 60m
2Capsicum face of blade and the back side (pepper powdery mildew occurs in vacuum side of blade, so the capsicum back side will be sprayed evenly).
(2) handle 2 (positive controls): with the pure and strong milk liquid of the own azoles of 3ml5%, join in the 4.5Kg water, stir, evenly be sprayed at 60m
2The capsicum face of blade and the back side.
(3) handle 3 (blanks):, evenly be sprayed at 60m with equivalent clear water 4.5Kg
2The capsicum face of blade and the back side.
4, investigation method:
Every dispenser in 7 days 1 time, 7 days investigation disease indexs after 3 dispensers.A situation arises for every duplication 10 strain pepper powdery mildews.
5, grade scale:
0 grade: the whole anosis leaf of strain;
1 grade: the sick leaf rate of whole strain is below 5%;
3 grades: the sick leaf rate of whole strain is at 6%-10%;
5 grades: the sick leaf rate of whole strain is at 11%-20%;
7 grades: the sick leaf rate of whole strain is at 21%-50%;
9 grades: the sick leaf rate of whole strain is more than 51%.
6, control efficiency computational methods:
