Final adjustment must be made for weed and row conditions. Nozzle sizes shown are based on field speeds of 4 to 6 miles per hour. Similar nozzle sizes are available from all manufacturers. Use of the nozzle listing above does not necessarily imply a recommendation of that brand only. Tests have shown that broadcast spray rates ranging from l5 to 40 gallons per acre give good results.
Smaller rates are more difficult to apply accurately.
This procedure determines the volume of spray your sprayer is applying. Eighty degree flat fan nozzles ranging in size from 8002E to 8005E for preemergence and 8002 to 8005 for postemergence application or their equivalent should be used. The throttle setting used both for timing the distance traveled and for collecting the spray should be the same as that to be used for spraying. Collect the spray from all nozzles on one row for the row length measured and record in fluid ounces the quantity of spray collected. Each fluid ounce of spray collected is equivalent to one gallon per acre of crop.
