Spray volume
This is the total volume of product diluted in water or another solvent applied per unit area of the treated field.

Spray volume is a critical parameter for any spraying operation. It determines the uniformity of coverage on plant surfaces, which directly dictates the effectiveness of pest, disease, or weed control.
When selecting the application rate, it is necessary to consider the type of equipment used, the crop growth stage, and the density of the foliage. Field crops typically require low-volume spraying, whereas orchards often necessitate higher volumes for thorough canopy penetration.
A common mistake is excessive cost-cutting through drastic reductions in spray volume, which leads to poor distribution of the active ingredient and may accelerate the development of resistance. Proper nozzle calibration is also essential to avoid product wastage and ensure environmental safety.
