Citrus Red Mite Control on Citrus in Louisiana, 1986

The study was conducted on a plot of'Washington’ navel citrus trees located at the LSU Citrus Research Station, Louisiana Agricultural Experiment Station, Port Sulpher, LA. A randomized complete block design was used with 4 replications per treatment (individual trees served as plots). Pesticides were applied on 18 Aug with a hand-held C02 pressurized sprayer delivering 0.5 1 per tree at 40 psi through a single spray nozzle containing a D-3 disc, No. 25 core, and 16 mesh strainer. Treatments were sprayed until completely covered. Evaluations were made on 26 Aug and 30 Sept by randomly selecting 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 stero-microscope, and the number of mites recorded.
