1. INTRODUCTION
The sprayers of the series VRA and VCRA are machines for agricultural plant protection in
wine yards and orchards. They transfer the protection agent with an air stream to the plants.
The success of the protection depends on the protection agent, the technique of the protection
and the user. However, we must not only look the efficiency of the spraying, we must also take
care of the environment and the best results always achieved by a symbiosis of the
components.
The series VRA and VCRA sprayers are state of the art products for agricultural plants
protection, their air deflector and fan constructed to provide the best results in plant protection.
Their construction reduces also the noise, the necessary horsepower and the burden on the
user.
With the sprayers series VRA and VCRA, we can protect the plants:
a) Sprinkle 800 - 1500 l/ha
b) Spraying
- Rough spraying 400 - 800 l/ha
- Fine spraying 100 - 400 l/ha
- Very fine spraying do 100 l/ha (only with electrostatic)
In modern plant protection we rarely use high amounts of water (800 - 1500 l/ha), because it is
uneconomical- the loss of the protection agent is enormous (The droplets combine and flow of
the leaf- by 1500 l/ha almost 50 %) and the pollution (ground water).
Spraying with 400 - 800 l/ha are already treated as concentrated plant protection, where the
concentration is from two to four times.
Fine spraying 150 - 400 l/ha has a concentration from four - eight times.
Very fine spraying comes in consideration only in use of electrostatic and spraying every
second row.
The quantity of the protection agent used depends on the technique used and the habitat of the
plant. With the use of our sprayers, you will be able to reduce the luxury consumption of the
protection agent, protect the environment and increase the productivity.
