Fogging and ULV (Aerosol) applications
- Spray droplets are optimally sized to improve targeting.
- No run off of chemicals compared to conventional high volume applications.
- Reduces labour costs considerably as the work is carried out more quickly.
- Avoids application of high volume spray (excess water) when disease is prevalent particularly during low light cold temperature conditions.
What is a fog application?
Typically a thermal fog has a droplet size from 0.15 - 10 micron and is characterised by a highly visible spray cloud. A standard cold ULV aerosol application produces droplet sizes of mainly 10 - 25 micron, but can produce droplets up to 50 microns through adjustment of the flow rate. A ULV aerosol application cannot be seen in the same way as a thermal fog. Fogging has extremely effective properties when it comes to pest and disease control. Such treatments can result in a quick reduction of an existing pest population when an effective fast acting insecticide is used.
A typical high volume (knapsack) spray droplet would be in the range of 100-200 micron. Fogging techniques produce far more droplets from the same volume of liquid and therefore improved pest targeting. Coverage is far more efficient, from which effective control follows (1ml of liquid would produce 556,000,000 droplets at a particle size of 15 micron).
Crop protection, disinfection, humidification, and odour control. Whatever your requirements we can match a machine to that use.
It is extremely important in many situations that good disinfection takes place, usually between crops or in animal houses. Droplets can be produced around 50 microns, which is optimal for animal house buildings with a degree of residual activity. The use of certain disinfectants when used with fogging techniques is an ideal treatment for end of season glasshouse salad crops such as tomatoes and cucumbers where diseases can be present. Ask Fargro for details.
Pest and Disease Control
Small droplet distribution is essential for many pests and diseases in order to have efficacious results. Small particles can penetrate dense foliage crops and difficult to reach situations where conventional high volume sprays fail. Quick pest knockdown with excellent crop safety can be achieved with fogging technology.
Many situations demand high humidity levels and Dynafog equipment can cater for that requirement.
