Abstract
The invention discloses a plant pesticide for controlling tomato canker, belonging to the technical field of pesticides. The plant pesticide disclosed by the invention is prepared by the following steps: selecting Chinese herbal medicines, namely sticktight, common sage herb, radix gentianae macrophyllae, cassia twig and trichosanthes kirilowii, grinding and uniformly mixing; putting in a closed container, adding appropriate 80% ethanol and extracting; and adding some auxiliaries into the extract to obtain the plant pesticide. Field trails prove that the plant pesticide realizes a good control effect without causing residue or environmental pollution.
Description
Technical field
The present invention relates to biological pesticide technical field, particularly relate to a kind of botanical pesticide and the preparation method that prevent and treat canker of tomato.
Background technology
All can there is canker to fruiting period in tomato seedling, leaf, stem, flower, fruit can be caught an illness and be injured.Seedling Stage: many from the leaf margin of plant lower blade, there is upwards vertical volume in sick leaf, and it is sagging upwards to wilt gradually from bottom, and like lack of water, turn yellow between sick limb edge and vein, blade browning look withered.Adult plant: germ is invaded by stem, expands from phloem to marrow.Carpopodium is injured many expansion by stem germ and cause its phloem and marrow and present brown and rot, and can extend in fruit in season, cause young fruit diapause, shrinkage, deformity, makes seed abnormal and carry disease germs, sometimes from sepal surface local infection, produce necrotic plaque, Spot expansion is to fruit face.Time moist, sick fruit surface produces " bird's-eye ", single lesion diameter about 3mm.Sometimes many bird's-eyes are sticked to the established practice and are formed atypic lesion together.At present, to the control of this disease mainly based on chemical pesticide, but chemical pesticide volatile in air, flow in water body, sedimentation is gathered in soil, pollute farming animals fishing fruit product, and transfer in human body by the enrichment of food chain, harm is produced to human body.Therefore, develop a kind of novel without poisoning, noresidue, biopesticide free from environmental pollution very important for field control.
Summary of the invention
The object of this invention is to provide a kind of noresidue, non-environmental-pollution, control efficiency significantly, a kind of botanical pesticide preventing and treating canker of tomato of being made up of pure Chinese herbal medicine.
The object of the invention is to be achieved through the following technical solutions, this botanical pesticide is made up of the herbal raw material of following weight portion: beggar-ticks 32-38 part, Common Sage Herb 40-50 part, bark of ash 45-55 part, cassia twig 44-50 part, snakegourd 38-44 part.
Preferred: beggar-ticks 35 parts, Common Sage Herb 45 parts, bark of ash 50 parts, cassia twig 47 parts, snakegourd 41 parts.
Preparation method: assorted by above weight portion by Chinese herbal medicine, shatter mixing, put into closed container, adds appropriate 80% ethanol.Ultrasonic oscillation 20min, carried out twice decompress filter (first time uses double-layer leaching net, and second time uses double-layer filter paper), obtain the solution clarified, 40 DEG C of rotary evaporations, make dense dose of 1g/ml, obtain this biopesticide.For improving the attachment of invention formulation, emulsification, high osmosis, bactericidal properties, adds the tween of 0.05-0.15% biopesticide weight, the fulvic acid of 2-3% biopesticide weight.
The characteristic of each Chinese herbal medicine: beggar-ticks has good inhibitory action to Gram-positive bacteria, staphylococcus aureus etc.; Common Sage Herb is to inhibitory action such as staphylococcus aureus, sarcine, hay bacilluses; Bark of ash has good inhibitory action to bacillus anthracis, staphylococcus, pneumobacillus, dysentery coccus etc.; Cassia twig is inhibited to Escherichia coli, hay bacillus, pneumococcus, Bacterium enteritidis etc.; Snakegourd has good inhibitory action to Escherichia coli, sonne bacillus, proteus etc.
The present invention has following beneficial effect: this botanical pesticide not only control efficiency is good, and is a kind of environmentally friendly agricultural chemicals, environmentally safe, noresidue, easily decomposes, meets the requirement of the development " green agriculture " that country advocates.
Field trial data
Use embodiment biopesticide 120 times, 200 times, 250 times and the withered Garrick of green grass or young crops 150 times of liquid below and contrast clear water, field control effectiveness test is carried out to canker of tomato.
Be positioned at oneself tomato of planting site and canker occur, test in first 6 days and process of the test and do not use other agricultural chemicals.Experimental field soil property is medium, and rich water is better, and management is consistent.This field trial adopts blue or green withered Garrick 150 times of liquid; 120 times of liquid of this biopesticide, 200 times of liquid, 250 times of liquid; Clear water (CK); Totally 5 process.Each process repetition 3 times, totally 15 process communities, select growing way and the basically identical field of morbidity to start phase the 1st medication in canker of tomato, after this every 7d medication 1 time, continuous 2 times, knapsack sprayer is used, amount of liquid medicine standard is 34kg/ 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 canker of tomato state of an illness, calculating disease index, control efficiency after each dispenser.3 points are evenly fixed in Cha Shimei community, often 10 strains, totally 30 strains.
Investigation result:
Different disposal to the control efficiency of canker of tomato as following table:
Sum up result of the test can draw, after twice dispenser, botanical pesticide of the present invention to the control efficiency of canker of tomato apparently higher than the withered Garrick of green grass or young crops 150 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 canker of tomato.
Embodiment
Embodiment one: take beggar-ticks 320 grams, Common Sage Herb 400 grams, bark of ash 450 grams, cassia twig 440 grams, snakegourd 380 grams, Chinese herbal medicine is assorted by above weight portion, shatters mixing, put into closed container, add appropriate 80% ethanol.Ultrasonic oscillation 20min, carried out twice decompress filter (first time uses double-layer leaching net, and second time uses double-layer filter paper), obtain the solution clarified, 40 DEG C of rotary evaporations, make dense dose of 1g/ml, obtain this botanical pesticide.For improving the attachment of invention formulation, emulsification, high osmosis, bactericidal properties, puts into the tween of 0.05-0.15% biopesticide weight and the fulvic acid of 2-3% biopesticide weight.
Embodiment two: beggar-ticks 350 grams, Common Sage Herb 450 grams, bark of ash 500 grams, cassia twig 470 grams, snakegourd 410 grams, preparation method is with embodiment one.
