Citrus Red Mite Control on Citrus, 1983

The study was conducted on mature trees located at the LSU Citrus Research Station, Port Sulpher, LA. A randomized complete block design was used with 4 replications per treatment (individual trees served as plots). Each plot was surrounded by 4 untreated trees to serve as a buffer between treatments. Pesticides were applied on 15 Jun ’83 with a FMC Speed Sprayer operated at 1200 RPM and 250 psi and a 4 nozzle hand gun. Trees were sprayed until runoff (approx 2.5 gal/tree). Evaluations were made on 29 Jun and 13 Jul by randomly selecting 10 leaves per tree as follows: 2 leaves from each of the 4 compass directions and 2 from the center of the tree. Leaves were taken to the lab, examined under a stereo-microscope, and the number of mites recorded.
