Do not add an extension to the boom unless the hose size for feeding the boom is also increased or the number of feeder lines is increased. Poor spray patterns have resulted when hose size was not changed. Be sure that spray lines have adequate capacity. If the hoses, connections and valves are too small, there is a drop in pressure. A flow velocity of 5 to 6 ft per second in the boom is recommended.
Sufficient agitation is necessary to keep the herbicide in suspension.
It is highly desirable to cut the agitation as the amount of solution in the tank is decreased. Some herbicides will floccuate with over-agitation. Flush spray lines with clean water after use or if spray operation is stopped for longer than 30 minutes. Some herbicides will settle out in the lines in a short period of time. Operation Crop damage can occur if the nozzles are allowed to drip during turns or when the sprayer is stopped for refilling or other reasons.
