Electrostatic Sprayers for Grape Growers
Some advantages and benefits:
How much chemical can you afford to waste?
It may surprise you, but only 15% to 20% of the spray from your conventional or air blast sprayer ends up on the plants. Nearly 60% of the chemical goes wasted onto the ground and less than 3% ends up on the undersides of leaves or other hidden areas. These percentages come from separate studies done at the Universities of Cal-ifornia, Georgia, Illinois and Chile. This means that for every 0 you spend for chemicals, only about worth ends up where you need it.
Use less, get more
With ESS systems many growers reduce their chemical amount by 1/2 and the amount of water by 20 times. But, less water doesn't mean less spray power. Figure 2 shows field test results of ESS at full and half chemical rates on grapes located at the interior of the cluster. Even at 1/2 chemical rate and 1/20th of the water, the ESS system put 3-times more on the interior grapes than the air-blast type conventional sprayer. Reduced chemical dosages work well with growth regulators too. The table grapes shown in Figure 3 had 1/2 rate applications of all chem-icals (including Gibberellic Acid and Ethrel) at only 5 to 8 gallons of water per acre.
