Spraying pesticides at a Volume Application Rate (VAR) of less than 5 L/ha for field crops and less than 50 L/ha for tree/bush crops is considered ultra-low volume (ULV).
For airborne ULV application to forest or migratory pests, VARs of 0.25 – 2 l/ha are usual. ULV spraying is a well-established spraying technique that is still employed by cotton growers. It’s also been employed in large-scale aerial spraying campaigns.
Cold ULV fogger machine
Cold ULV fogger machines, also known as ultra-low volume (ULV) ULV fogger machines, employ enormous volumes of air at low pressures to convert liquid into droplets that are distributed into the atmosphere. This fogging machine is capable of producing incredibly minute droplets. Pesticides, herbicides, fungicides, sterilizers, and disinfectants, among other chemicals, are applied using ULV machines. Each application has an appropriate droplet size, hence the size of the droplet is critical. Flying insects require droplet sizes of 5 to 20 m, leaf nematodes require droplets of 20 to 40 m, and fungi require droplets of 30 to 50 m. The term “low volume” alludes to the small amount of carrier fluid required by these machines.
Purpose of a ULV fogger machine
Pesticides or disinfectants are compressed through a specifically designed nozzle, resulting in a thin cold mist or aerosol. Electric portable models are especially suitable for indoor use because they do not emit exhaust fumes and are quieter.
Benefits of ULV fogger machine:
Cost-effective
ULVspraying is a method of applying pesticides in small amounts to provide cost-effective insect management. In this pesticide application approach, the volume of pesticide applied per acre is less than 5 liters, which is exceedingly low when compared to the traditional High Volume Technique.
Controlled Application
The insecticide liquid is broken into droplets by centrifugal energy in the rotary atomizer. The ULV fogger machine droplet diameter range produced by centrifugal nozzles is typically narrow. Thus provides a controlled application of pesticides.
Good for water scars areas
In arid terrain places where water is scarce and conventional high-volume spraying is not practical, ULV spraying is effective. Because of the specific ULV formulations, this technique is also known as waterless spraying. However, because ULV formulations are now unavailable, this method’s advantage is not being used.
Covers a maximum surface
Due to the small droplet size, and spraying with a certain pressure, the ULV fogger ensures the coverage of the maximum surface area with lesser effort. Also, small droplets ensure the optimal density of the pesticide giving better results
Controlled Droplet size
Droplet Sizes can be controlled in the ULV fogger machine. Controlling the droplet size has several advantages: when it is considerably smaller, it can penetrate small nooks and crannies and stay in the air longer; when used outside, you can choose a larger droplet size to avoid being blown away by the wind.
Varied RPMs on the same flow rate of liquid will produce different micron sizes of droplets and different throw levels, with the higher RPM (Rounds per Minute) model covering a greater distance.
Speedy Application
70 percent faster application than traditional spraying significantly reduces labour cost Fine mist dispersion reduces chemical/disinfectant used by over 65 percent compared to traditional spraying
Conclusion:
PADCORP’s ULV cold fogger employs aerosol, air-shear (mist-blowers, exhaust gas sprayers), or, better still, spinning nozzle approaches. PADCORP is a renowned ULV fogger supplier. Because the droplet size is exceedingly small, i.e. 5 -50 microns, these PADCORP ULV fogger machines are the most effective for disinfecting & sanitizing your surroundings to prevent the spread of deadly viruses.
