Abstract
The invention discloses a method for preventing and treating bacterial leaf spots of soybeans. The method includes the steps that seeds are selected, disease and pest seeds are abandoned, and seeds of a high-yield and high-quality disease-resistant variety are planted; reasonable rotation is conducted, bacterium sources are reduced, and the resistance of soybean plants is enhanced; ploughing is conducted for cleaning stubbles, the bacterium sources are reduced, plant residues are turned underground during autumn ploughing, and the disease occurrence degree is reduced; biopesticide prepared from Chinese herbal medicine of cordyceps sinensis, caryopteris incana, nutmeg, dragonhead and melastoma polyanthum is adopted for prevention and treatment. It is proved through a field experiment that the prevention and treatment effect is good, no residue or pollution is generated, and safety and reliability are achieved.
Description
Technical field
The present invention relates to control of plant disease technical field, particularly relate to a kind of method of preventing and treating soybean bacterial leaf spot.
Background technology
Soybean bacterial leaf spot mainly contains bacterial speck and bacterial speck two kinds.Bacterial speck forms water soaked spots at first on blade, and later overstrike or black polygonal spot, there is yellow green haloing at edge.Diseased tissues is easily withered to come off, and sick leaf is broken shape.Stem and petiole produce pitchy streak by sick.Pod produces bronzing point by sick, after become irregular shape stigma, focus mostly in beanpod commissure.Germ forms brown spot on seed, above has one deck bacterial ooze.Bacterial speck symptom is similar to spot disease, and the main distinction exists: macula scab point is small and dense, and the initial stage, the haloing at edge was not obvious not in water stain shape, and there are protruding little rash in the central authorities of spot, and time serious, on leaf, many scabs mutually converge rear sheet and organize withered.At present, the control of soybean bacterial leaf spot mainly based on chemical agent, although certain control efficiency can be reached, to the pollution of environment with can not be ignored the harm that human health causes.Based on this, inventor, in long control practice, has found out the prevention and controls of a set of environmental protection based on biopesticide.
Summary of the invention
The object of this invention is to provide a kind of control efficiency significantly, the method for the control soybean bacterial leaf spot of non agricultural chemical residuum, non-environmental-pollution.
The object of the invention is to be achieved through the following technical solutions, the method for this control soybean bacterial leaf spot comprises the following steps:
(1) elite seed, eliminates sick worm grain, plantation high yield and high quality disease-resistant variety.
(2) carry out the efficent rotation change of crops, reduce germ source, strengthen soybean plant strain resistance.
(3) plough stubble-cleaning, reduce germ source, the autumn turns over and plant residue is ploughed under underground, alleviates disease occurrence degree.
(4) chemical control, the biopesticide control adopting Chinese herbal medicine to make, namely take Chinese medicine Cordyceps sinensis 250 grams, cayropteris incana 350 grams, nutmeg 360 grams, dragonhead 450 grams, manyflower melastoma herb 260 grams be pulverized and mixed, the water adding 18L, 10L, 10L respectively endures 3 times, often all over boiling 2L merging filtrate, and with multilayer gauze and Filter paper filtering, the filtrate after heating merges is concentrated into 2L and makes aqua, obtains biopesticide of the present invention.
The characteristic of each Chinese herbal medicine: Cordyceps sinensis has certain inhibitory action to common bacterium, fungi; Cayropteris incana has certain inhibitory action to staphylococcus aureus and diphtheria, typhoid fever, paratyphoid B, A type, green pus, large intestine, shigella dysenteriae etc.; But nutmeg has sterilizing function; Dragonhead has stronger inhibitory or killing effect to Bacillus influenzae, Diplococcus pneumopniae, A type and beta streptococcus, Neisser's coccus etc.; Manyflower melastoma herb has inhibitory or killing effect to hemolytic streptococcus, staphylococcus aureus, typhoid bacillus, bacterium flexneri, Pseudomonas aeruginosa etc.
Beneficial effect of the present invention: to crop without key, noresidue, free from environmental pollution and agricultural product, do not kill natural enemy, to mammal without harm such as teratogenesis, carcinogenic, mutagenesis, highly effective and safe, preventive effect is good.
Field trial data
1, in soybean planting garden, Yinan County, Shandong Province, soybean bacterial leaf spot is prevented and treated, set up experimental group, 50% sporgon missible oil group, control group: when other condition is identical, the biopesticide control that experimental group adopts Chinese herbal medicine of the present invention to make; 50% sporgon missible oil group selects the 1000 times of liquid spraying controls of 50% sporgon missible oil, and control group is clear water group.
2, primary condition: soil is clay loam, fertility is general, and managerial skills are better.
3, experimental scheme: 80,120 times of liquid, two concentration are established in biopesticide field, are watered dose 30kg/ mu.50% sporgon missible oil group reagent agent selects the 1000 times of liquid spraying controls of 50% sporgon missible oil, being watered dose 30kg/ mu, totally 4 process, repeating for 3 times, to starting to occur that the blade of scab carries out dispenser, using the spraying of sprayer quantitative and even.
4, within 7 days, start to investigate after investigation content and method dispenser, take five point samplings, fixed point adventive, determine the way of the indefinite leaf of the number of sheets, often some investigation 18 blades (6, bottom, 6, middle parts, 6, top), the classification investigation state of an illness, the statistics incidence of disease and disease index, calculate control efficiency.Severity Scaling standard: 0 grade, without scab on leaf; 1 grade, lesion area accounts for whole leaf area less than 5%; 2 grades, lesion area accounts for 6% ~ 10% of whole leaf area; 3 grades, lesion area accounts for 11 ~ 20% of whole leaf area; 4 grades, lesion area accounts for 21 ~ 25% of whole leaf area, 5 grades, and lesion area accounts for more than 50% of whole leaf area.
Disease index (%)=Σ (number of blade of sick level × this sick level) × 100/ the highest sick level × total leaf number.
Control efficiency (%)=(contrast disease index-process disease index) × 100/ contrast disease index.
5, result of the test: biopesticide 80,120 times of liquid control efficiency are respectively 84%, 79%, and all apparently higher than 50% sporgon missible oil, 1000 times of liquid, its control efficiency is 69%; Experimental group is compared with 50% sporgon missible oil group, and control efficiency is remarkable.
Embodiment
The method of this control soybean bacterial leaf spot comprises the following steps:
(1) elite seed, eliminates sick worm grain, plantation high yield and high quality disease-resistant variety.
(2) carry out the efficent rotation change of crops, reduce germ source, strengthen soybean plant strain resistance.
(3) plough stubble-cleaning, reduce germ source, the autumn turns over and plant residue is ploughed under underground, alleviates disease occurrence degree.
(4) chemical control, the biopesticide control adopting Chinese herbal medicine to make, namely take Chinese medicine Cordyceps sinensis 250 grams, cayropteris incana 350 grams, nutmeg 360 grams, dragonhead 450 grams, manyflower melastoma herb 260 grams be pulverized and mixed, the water adding 18L, 10L, 10L respectively endures 3 times, often all over boiling 2L merging filtrate, and with multilayer gauze and Filter paper filtering, the filtrate after heating merges is concentrated into 2L and makes aqua, obtains biopesticide of the present invention.
