Backpack Mistblowers

Backpack mistblowers have a small gasoline-powered engive that drives a fan similar to a leaf-blower. The liquid pesticide is in a typically 3-gallon tank. The nozzle is gravity fed, and the pesticide falls into the air-stream where it is broken into fine droplets.

Advantages:

• provides excellent coverage
• suitable for spot treatments
• control settings allow adjustment of spray volumn to suit needs
• sprays several feet to allow treatment of tall trees

Disadvantages:

• highly driftable
• is expensive for a hand-held uinit
• is heavy and noisey for the operator
• may result in pesticide exposure for the operator
• sprayer only holds a few gallons so requires frequent fill-ups
• very labor intensive

Most Effective Spray Pattern:

Treat trees from opposite directions. Treat no more than 2 rows at a time.
