A Review of Electrostatic Spraying for Agricultural Applications

Abstract

Pesticides are toxic chemicals designed to control certain pests, diseases or weeds.

They can easily contaminate the air, ground, water sources, wild animals, birds and aquatic life

when they run-off from fields. For these aspects the application of pesticide must be done

accurately. One of the most important factors that affecting the success of application is choosing

the right equipment. New technologies on sensor and image analyzing process promoted the

success of application technique. Besides electrostatic spraying is a new trend to apply pesticides

with less drift potential. In recent years electrostatic spraying has been used in many other

applications such as painting, ink printing etc. Researches have indicated electrostatic spraying

achieves better coverage of difficult targets than conventional spraying. Water consumption of that

kind of sprayers is up to 10 times less than conventional spraying. On the other hand this method

has some difficulties and disadvantages. In this study, electrostatic spraying in agricultural

application was evaluated. Tractor mounted and mobile knapsack electrostatic sprayers were

explained and some experimental results of them were discussed.
