Abstract
The invention discloses a biopesticide for controlling walnut black spot and a preparation method, belonging to the technical field of pesticides. Chinese herbal medicines, namely radix gentianae macrophyllae, cassia twig, radish, calendula officinalis, spanishneedles herb, hyperforin perforatum, thomson sreeper root or stem and kaleniczenk euphorbia herb, are subjected to grinding and ethanol extraction to obtain the biopesticide. According to field control trials, the control effect on walnut black spot is better than that of the control group; and particularly, the biopesticide is prepared from pure natural Chinese herbal medicines so as to avoid environmental pollution and residue.
Description
Technical field
The invention belongs to biological pesticide technical field, particularly relate to a kind of biopesticide and the preparation method that prevent and treat walnut black spot.
Background technology
Walnut black spot is also known as black rot, and main harm young fruit, blade, also can endanger spray.Young fruit is caught an illness, and small brown specks of really looking unfamiliar, edge is not obvious, and rear blackening in blocks reaches pulp deeply, causes whole walnut and the whole blackening of kernel or rots to come off.After almost ripe fruit is caught an illness, be first confined to exocarp, after feed through to mesocarp, cause pericarp disease portion and come off, endocarp exposes, and kernel is intact.Blade is caught an illness, first existing subcircular or the little foxiness of polygonal on vein, healing mutually after expansion, scab peripheral unboiled water stain shape haloing, later stage a few perforations, sick leaf shrinkage deformity.This disease of current control is main based on chemical pesticide, but the high residue of chemical pesticide, cause the pollution to environment.A large amount of agricultural chemicals evaporate in air, flow in water body, sedimentation is gathered in soil, pollutes farming animals fishing fruit product, and transfers in human body by the enrichment of food chain, produce harm to human body.For this reason, inventor is in prevention practice for many years, and the biopesticide control walnut black spot utilizing Chinese herbal medicine to make, not only control efficiency is good, and pollution-free, non agricultural chemical residuum, and walnut quality is good.
Summary of the invention
The object of this invention is to provide a kind of control efficiency significantly, the biopesticide of the control walnut black spot of non agricultural chemical residuum, non-environmental-pollution.
The object of the invention is to be achieved through the following technical solutions, the biopesticide of this control walnut black spot is made up of the Chinese herbal medicine of following weight portion: bark of ash 32-42 part, cassia twig 40-50 part, radish 38-44 part, pot marigold 42-50 part, railway beggarticks herb 30-36 part, hypericum perforatum 40-50 part, thomson sreeper root or stem 23-29 part, kaleniczenk euphorbia herb 33-39 part.
Preferred: bark of ash 37 parts, cassia twig 45 parts, radish 41 parts, pot marigold 46 parts, railway beggarticks herb 33 parts, hypericum perforatum 45 parts, thomson sreeper root or stem 26 parts, kaleniczenk euphorbia herb 36 parts.
Preparation method: take Chinese herbal medicine according to the weight portion of technique scheme and carry out pulverization process, crosses 50 mesh sieves after pulverizing, is distributed into lower part of screen in closed container, add appropriate amount of ethanol, just submergence herb medicine is advisable, and covers dipping, stir, place after 5 days, incline and supernatant; Add 50% ~ 75% appropriate amount of ethanol again in the dregs of a decoction, flood 5 days according to upper method, incline to, merge two liquid, stir evenly and obtain this biopesticide.
Each Chinese herbal medicine characteristic: bark of ash has stronger inhibitory action to bacillus anthracis, staphylococcus, typhoid bacillus, pneumobacillus, shigella dysenteriae, comma bacillus etc.; Cassia twig has good inhibitory action to staphylococcus albus, Shigella shigae, aerobacteria, proteus, bacillus anthracis etc.; Radish has antibacterial action widely, especially to Gram-positive bacteria; Pot marigold has antiphlogistic antibacterial effect, better to effects such as staphylococcus, streptococcus and some fungi especially, has killing action to virus; Railway beggarticks herb is inhibited to bacteriums such as staphylococcus aureuses; Hypericum perforatum has good inhibitory action to gram-positive bacteria, staphylococcus, pneumococcus, hemolytic streptococcus etc.; Thomson sreeper root or stem, kaleniczenk euphorbia herb be clearing heat and detoxicating, draw out pus by applying a plaster to the affected part, have certain antibacterial action;
Beneficial effect of the present invention: biopesticide of the present invention without poisoning, noresidue, free from environmental pollution and agricultural product, has highly effective and safe to crops, the advantage that preventive effect is good.
Field trial data
Use embodiment biopesticide 100 times, 150 times, 200 times and 72% agricultural streptomycin soluble powder, 4000 times of liquid below and contrast clear water, field control effectiveness test is carried out to walnut black spot.
Be positioned at the walnut that black spot occurred oneself planting site and carry out the test of pesticide effectiveness.Experimental field soil property is medium, and rich water is better, and management is consistent.This field trial adopts 72% agricultural streptomycin soluble powder, 4000 times of liquid; 100 times of liquid of this biopesticide, 150 times of liquid, 200 times of liquid; Clear water (CK); Totally 5 process.Each process repetition 2 times, totally 10 process communities, select growing way and the basically identical field of morbidity to start phase the 1st medication in walnut black spot, after this every 7d medication 1 time, continuous 2 times, high-pressure sprayer is used, amount of liquid medicine standard is 35kg/ mu, and every strain is all subject to medicine even, avoids liquid to drift about.After first time dispenser, second time medicine is executed at interval after 7 days, altogether dispenser twice.The 7th afternoon unified investigation walnut black spot state of an illness, calculating disease index, control efficiency after each dispenser.2 points are evenly fixed in Cha Shimei community, often 2 strains, totally 4 strains.
Investigation result:
Different disposal to the control efficiency of walnut black spot as following table:
Sum up result of the test can draw, after twice dispenser, biopesticide of the present invention to the control efficiency of walnut black spot apparently higher than 72% agricultural streptomycin soluble powder, 4000 times of liquid.The process of biopesticide 3 variable concentrations along with the increase of spraying times is in rising trend, reaches good control efficiency to the control efficiency of walnut black spot.
