Ozonation in beekeeping is used to disinfect hives, frames and combs from bee disease pathogens. Treatment with moderate ozone concentrations has a beneficial effect on colony activity.
Regular ozonation reduces pathogenic microorganisms, decreases humidity in the hive air and improves gas composition. As a result, treated colonies showed an increase in marketable honey production of 25 kg per season compared to the control group.
Ozone applications in beekeeping
- Comb disinfection from chalkbrood (ascosphaerosis) pathogens
- Hive and frame treatment for foulbrood diseases
- Varroosis control in complex therapy
- Improved hive microclimate
- Beekeeping equipment disinfection
- Nosemosis and other infection prevention
- Wintering house and apiary building treatment
Chalkbrood control
| Infection level | O₃ concentration | Treatment time | Frequency |
|---|---|---|---|
| Prevention | 100-150 mg/m³ | 30-45 min | Once a month |
| Mild form | 200-250 mg/m³ | 60 min | Twice daily, 5-7 days |
| Moderate form | 250-350 mg/m³ | 60 min | Three times daily, 7-10 days |
| Severe form | 400-500 mg/m³ | 60-90 min | Four times daily, 10-14 days |
Effectiveness against various pathogens
| Pathogen/disease | O₃ concentration | Time | Effectiveness |
|---|---|---|---|
| Ascosphaera apis (chalkbrood) | 250-500 mg/m³ | 60 min | 50-77% |
| Paenibacillus larvae (American foulbrood) | 300-500 mg/m³ | 60-90 min | 85-95% |
| Melissococcus plutonius (European foulbrood) | 250-400 mg/m³ | 45-60 min | 90-98% |
| Nosema apis (nosemosis) | 200-300 mg/m³ | 30-45 min | 80-90% |
| Aspergillus (aspergillosis) | 300-500 mg/m³ | 60-90 min | 85-95% |
| Deformed wing virus | 150-250 mg/m³ | 30-45 min | 70-85% |
Stimulating effect of ozone
| Indicator | Control group | Treated group | Difference |
|---|---|---|---|
| Honey yield, kg/season | 45-50 | 70-75 | +25 kg (+50%) |
| Colony strength, frames | 8-10 | 12-14 | +40% |
| Queen egg-laying, eggs/day | 1200-1400 | 1600-1800 | +30% |
| Brood rearing | 100% | 135-140% | +35-40% |
| Wintering (losses) | 15-20% | 5-8% | -60% |
| Swarming | Frequent | Rare | 2-3 times reduction |
Comb and equipment treatment
| Treatment object | O₃ concentration | Time | Note |
|---|---|---|---|
| Combs (prevention) | 200-300 mg/m³ | 30-45 min | After honey extraction |
| Combs (disinfection) | 400-600 mg/m³ | 60-90 min | In case of diseases |
| Empty hives | 300-500 mg/m³ | 45-60 min | Before settling |
| Metal equipment | 500-700 mg/m³ | 30-45 min | Smokers, hive tools |
| Protective clothing | 300-400 mg/m³ | 30-45 min | In ozone chamber |
| Honey containers | 200-300 mg/m³ | 20-30 min | Before filling |
Seasonal ozonation calendar
| Period | Treatment type | Concentration | Purpose |
|---|---|---|---|
| Early spring (March) | Stimulating | 10-15 mg/m³ | Colony activation after wintering |
| Spring (April-May) | Preventive | 100-200 mg/m³ | Spring infection prevention |
| Summer (June-July) | Stimulating | 10-15 mg/m³ | Honey yield increase |
| After extraction (August) | Comb disinfection | 300-500 mg/m³ | Disinfection of freed combs |
| Autumn (September) | Preventive | 150-250 mg/m³ | Wintering preparation |
| Wintering house (November) | Disinfection | 400-600 mg/m³ | Wintering house treatment before placement |

Increase in marketable honey by 25 kg per colony per season with regular ozonation
Disease control
Effectiveness against chalkbrood, foulbrood, nosemosis and other infections
Improved wintering
2-3 times reduction in colony losses during wintering thanks to bee health improvement
Reduced swarming
Stimulating ozonation reduces colony tendency to swarm by 2-3 times
Economic benefit
Equipment payback in 1-2 seasons through increased apiary productivity
