Abstract: Application of spray coatings in paint industry and spray of weedicide and foliar chemicals in agriculture have been common practice to get better results. There are number of methods have been introduced to give electro-static-charge to spray drift to get better coverage. In theory, negatively charged spay drift is attracting to grounded objects (positively charged) or vice versa. There are various types of electro-static nozzles designed to achieve the expected result of electro static spray. Most of the time there are specific nozzles designed for particular purposes. At the moment some electro static sprayers are built in with spray nozzle with single point electro-static discharge units. As rule of thumb, due to better results and complex design, electro static nozzles and electro static sprayers are expensive than non-electro-static-sprayers. Particularly in agriculture and horticulture industry, the cost of electro static sprayer sprayers are very high and difficult to afford for small to medium scale farmers. Multi Point Electro-Static Discharge Adaptor for Spray Nozzle will provide sustainable and low cost solution to anybody who wants to improve the efficiency and coverage of usual spray. The Multi Point Electro-Static Discharge Adaptor for Spray Nozzle consists of bunch of electric conductive materials such as carbon fibre or metals with number of pin points, covered by electric insulations such as ceramic, plastic, rubber or any other polymers and attaching mechanism to usual spray nozzle. The mentioned Multi Point Electro-Static Discharge Adaptor for Spray Nozzle can be connected to common high voltage electro static generators with proper insulation wire. The main advantages of this innovation is low cost and the user doesn't want to invest on complete electro-static sprayer which is normally very high in cost compared to same category of sprayers. Multi point discharge adapter is highly efficient in discharging negative or positive corona compared to single point discharger. Due to that low level of high voltage (< 6,OOOV) can be used with this Multi Point Electro-Static Discharge Adaptor. It will help to minimize electric hazards in field condition compared to very high voltage sprayers (> 1 O,OOOV). This innovation will improve the spray efficacy and coverage of the spray remarkably while reducing free spray drift and will reduce air pollution. And the user will have ability to change the type of high voltage generator and the voltage according to achieve desired results. As any other high voltage equipment, all the necessary precautions and safety equipment should be in placed while using and handling of this Multi Point Electro-Static Discharge Adaptor too. 6| Figure 1.
