What are the advantages and disadvantages of agricultural electrostatic sprayers?
Minute quantity can be applied but not affordable for small farmers in developing nations due to high cost.
Electrostatic spraying is a new trend to apply pesticides with less drift potential. In recent years electrostatic spraying has been used in agriculture spraying.
Advantages
1. Researches have indicated electrostatic spraying achieves better coverage of difficult targets than conventional spraying.
2. Water consumption of that kind of sprayers is up to 10 times less than conventional spraying.
3. Electrostatic guns have very high transfer efficiency which means less money spent on
4. Electrostatic guns not only provide better finish quality, compared to conventional air spray and HVLP guns, but they also reduce VOC emissions and improve production speeds.
5. Increased spray efficiency, increased spray efficacy, lower economic costs, greater safety and less damage to the environments.
6. Since the electrostatic system saves time and provides better coverage, the overall cost per acre is less than with higher volume dilute sprayers. Electrostatic sprayers use an average of 70% less fuel and 25% less pesticide per acre than non-electrostatic dilute sprayers, and application costs average 20% less per acre.
7. Using less pesticide per acre increases worker safety and also reduces the potential for environmental damage. Pesticides applied with an electrostatic sprayer are applied directly to the target pest with minimal run-off or overspray
8. A major advantage of electrostatic sprayers is that they can save about 90% water, so its normal flow indicator should be 5-15 liters per hour, usually not more than 20 liters
9. The average electric sprayer flow of up to 60-80 liters per hour, spraying acres of land area may consume 48 liters of water. If you find that a bucket of water can be sprayed in about 10 minutes, you can basically assume it is just an ordinary electric sprayer.
Disadvantages
1. On the other hand this method has some difficulties and disadvantages. In this study, electrostatic spraying in agricultural application was evaluated. The some of the item costly.
2. Contamination of the environments
3. Leaving residue in food.
In agriculture, electrostatic spraying application is mostly adopted in crop protection to prevent pest infestation, improve product quality and to maximize yield.
