Spraying Information

 

THE PERFORMANCE OF ANY AGRICULTURAL CHEMICAL DEPENDS UPON THE PROPER APPLICATION OF THE CORRECT AMOUNT BASED ON THE CHEMICAL MANUFACTURERS RECOMMENDATION. BE SURE THAT YOUR EQUIPMENT HAS BEEN PROPERLY CALIBRATED BEFORE SPRAYING.

IN THE FIELD
Having established the proper spray tip style and size, spraying pressure and nozzle spacing the tractor throttle setting to provide the required rig speed should be determined. Because of wheel slippage, the actual rig speed, as determined from the tables below, may differ from the speedometer readings. Mark off a distance of 100, 200, and 300 feet in a field where the spraying is to be done - and run the tractor over this distance, carefully marking the throttle setting or speedometer reading. To make measurement of the test run, begin from standing start far enough ahead of first marker so that your rig is at full speed before traveling the 100, 200, or 300 foot distances.

SPRAY COVERAGE INFORMATION
This table lists the theoretical coverage of spray patterns as calculated from the included spray angle of the spray and the distance from the nozzle orifice. These values are based on the assumption that the spray angle remains the same throughout entire spray distance. In actual practice, the tabulated spray angle does not hold for long spray distances.

AFTER SPRAYING
Rinse And Clean All The Spraying equipment - including the spray tips, being careful not to use a metal probe in the orifice. This cleaning routine is especially important after spraying wettable powders. Wash spray tips thoroughly with water or cleaning solution (appropriate for chemical sprayed). Blow out orifice clean and dry. If orifice remains clogged, clean it with a fine bristle (not wire) brush or with a toothpick. Do nor damage the orifice. Water - rinse and dry tips before storing.
