A randomized block design was used with 4 single-tree replicates per treatment. Materials were applied using a Hardie hand-gun (single nozzle, no. 8 disk) at 450 psi (ca. 1000 gal/acre, 10 gal/tree) using a John Bean sprayer. Naked-eye counts of live adult female mites on the adaxial surfaces of 32 leaves/tree (4 leaves from each of two 4-leaf terminals per quadrant) were made. Predator mites (mainly Euseius tularensis) were censused by counting all motile stages on both sides of 10 inferior leaves/tree.
