Abstract
The invention discloses a fungicide for inhibiting potato leafroll disease, and relates to potato cultivation technology. The fungicide is characterized by comprising the following bulk drugs, by weight: 3-5% of Zhongshengmycin, 32-35% of zineb, 10-15% of dimethyl sulfoxide, 10-15% of calcium lignosulfonate, 2-5% of sodium dodecyl benzene sulfonate, 5-8% of Twain-80, 3-4% of white carbon black, 0.5-1% of fungus polysaccharide aqueous solution, and 15-19.5% of Viruside wettable powder. The invention has the following beneficial effects: the fungicide effectively controls potato leafroll disease, has easily available raw materials, low price, simple process, convenient usage, no pollution to the environment and no residue, and is a long-term biological fungicide with reasonable formula, high utilization rate of nutrient and good application effect. Application of the fungicide in potato planting solves potato resistance caused by use of traditional drug.
Description
Technical field
The present invention relates to the planting technology of potato, specifically a kind of bactericide of inhibition of potato leaf curl.
Background technology
Corium solani is most important Potyvirus venereal disease evil, and occur very general in the country of all plantation potatos, the production loss of susceptible kind can up to 90%.China is potato big producing country, due to continually developing of potato, in order to meet the growing market demand of potato, and peasant's establishing in large scale potato.
But in the real process of agricultural production, the problem that controlling disease the most easily produces is the drug-fast generation of germ.Initial symptoms is that epidemic season is caused by aphis propagation infection, and upper blade is curling, especially the base portion of leaflet.These blades are tending towards upright and are generally faint yellow.For many kinds, their color may be purple, pink or red.Forth infection may not have symptom, and some kind infects rear not symptom.Obvious slough is had in the stem tuber potato meat of high sense kind; Secondary symptom (plant grown up to from infected stem tuber be radical leaves curling, downgrade, vertical-growth and upper blade turn white.Hardening and the keratin of curling blade, their back side is purple sometimes; Andean subspecies reactions vary sample: it occurs and alternate chlorosis from edge, especially the obvious vertical growth of upper blade, usually serious dwarfing.General lower blade is not curling.Be inevitable by aphid natural propagation, the stem tuber also by infecting is propagated; Easy generation resistance; Some conventional medicaments preventing and treating early blight all need rotation use or use with other composite reagent.
The disease of resistance is agriculturally produced for control, a kind of way be release new for the new component of existing kind without cross resistance.But the new development cost of educating effect composition is high, and the construction cycle is long, and forever all produces the speed of resistance less than germ.Other method, as crop structure adjustment, different agricultural chemicals rotations etc., in the process of practical operation, is difficult to really play obvious effect.
The composition of different cultivars carries out composite, is to prevent and treat the very common way of resistance germ.Heterogeneity is carried out composite, according to the effect of practical application, judge certain composite be synergy, add and or antagonism.Compound synergic is well filled a prescription, and owing to significantly improving actual control efficiency, reduces the usage amount of agricultural chemicals, thus has delayed the drug-fast generation of germ greatly, is the important means of integrated control disease.Current Zhongshengmycin and zineb composite and apply and there is no people and reported.
Summary of the invention
The object of the present invention is to provide a kind of application of long-acting biological bactericide in potato planting reasonable, plant recovery of nutrient is high, effect is good of filling a prescription, solve after traditional medicament uses and cause potato to produce resistance.
For achieving the above object, the bactericide of a kind of inhibition of potato leaf curl of the present invention, it is characterized in that: count by weight, its bulk drug is: Zhongshengmycin 3 ~ 5%, zineb 32 ~ 35%, dimethyl sulfoxide (DMSO) 10 ~ 15%, calcium lignosulfonate 10 ~ 15%, neopelex 2 ~ 5%, Tween-80 5 ~ 8%, white carbon 3 ~ 4%, mushroom derived protein amylase 0.5 ~ 1%, virus must gram wetting powders 15 ~ 34.5%.
The preparation method of the bactericide of a kind of inhibition of potato leaf curl of the present invention, is characterized in that:
After Zhongshengmycin 3 ~ 5% is mixed with the zineb 32 ~ 35% adding dimethyl sulfoxide (DMSO) 10 ~ 15%, add dispersant calcium lignosulfonate 10 ~ 15%, wetting agent neopelex 2 ~ 5%, Tween-80 5 ~ 8% and a certain amount of aqua sterilisa again and be made into mother liquor, add white carbon 3 ~ 4%, mushroom derived protein amylase 0.5 ~ 1% again, virus must gram wetting powder 15 ~ 34.5%, breaks into 600 object wetting powders with airslide disintegrating mill; This formula is by 1800 ~ 2200 times of dilution sprayings, and after medicine, 8 ~ 14 days control efficiency are 92.3% ~ 94%.
Described potato leaf roll is infected by aphid, as black peach aphid, cotten aphid etc.; During plant strain growth, virus is by the propagation such as insect or juice, cause and infect again, high temperature is soil temperature high (> 25 DEG C) particularly, both be conducive to the breeding and the activity of biography poison that pass virulent aphis worm, and the vitality of potato block can have been reduced again, thus weaken the resistance to virus, often easily susceptible, cause potato seed to degenerate.
First the application of described prevention and controls will set up anosis potato seed breeding field, away from potato production field, and selects virus-free potato seed, and will strengthen cultivation management, promote precocious, ensure volume increase, and avoid tying potato under hot weather.Therefore, must suit measures to local conditions, begin sowing in good time, high bedding cultivation, reasonable fertile, pull out diseased plant etc.
Described Zhongshengmycin: zineb is 1:1 ~ 40 proportioning, with aqua sterilisa, mother liquor is diluted to suitable series concentration.
Described Zhongshengmycin and zineb mixture, have fine control efficiency to potato leaf roll germ.
Zhongshengmycin is a kind of novel bactericide.Belong to a kind of N-glucoside antibiotic.Its has a broad antifungal spectrum, all has good result to various bacteria, fungi.Very good effect is had to Gram-negative and positive bacterium.Protoplasm cohesion in hyphal cell can be caused to fungi, have strong inhibitory action to the sprouting of pathogen spore.With conventional dose without cross resistance.
Zineb is a kind of broad spectrum protection bactericide.Fine prevention effect is had to multiple diseases.Its effective ingredient is easily oxidized to different thiocyanation compound in water, has strong inhibitory action to the enzyme containing-sh base in pathogen.
The bactericide of a kind of inhibition of potato leaf curl of the present invention, its beneficial effect is: the present invention effectively prevents and treats potato leaf roll, and invention raw material is easy to get, cheap, technique is simple, easy to use, environmentally safe, noresidue is a kind of application of long-acting biological bactericide in potato planting reasonable, plant recovery of nutrient is high, effect is good of filling a prescription, and solves after traditional medicament uses and causes potato to produce resistance.The mechanism of action of the various compositions of bactericide of the present invention is different, mutual synergy between them, and the pesticide resistance of germ reduces, so the bactericidal effect of bactericide of the present invention is apparently higher than the bactericidal effect of single component.
