ABSTRACT:
A backpack sprayer for spraying arthropods or arthropod eggs, such as beneficial mites or beneficial insect eggs, or insect eggs containing parasitoids, directly onto plants is disclosed which uses excess air generated by a compressor to produce a coarse or fine spray of an aqueous suspension containing the arthropods or eggs as they exit from a spray gun. A stir bar magnet in a spray tank, controlled by a magnetic stirrer motor, keeps the arthropods or eggs evenly suspended in an aqueous solution. The sprayer provides an economical and alternative strategy for the delivery of arthropods such as beneficial mites and eggs to agricultural commodities.
