Abstract Nexter at three rates per acre was compared to Agri-mek + petroleum oil for efficacy against CRM in three water volumes. Treatments were assigned to 3 X 3 (=9 tree) plots in a RCB design, replicated 5 times on 10 ft tall trees with 7.5 X 25 ft spacing. Treatments were applied on 28 Jun (150 gpa), 29 Jun (200 gpa) and 30 Jun (250 gpa) using an FMC 352-S PTO airblast sprayer with speed, nozzling and pressure (160 psi) adjusted to apply the designated gpa. At each evaluation date, 20 fruit were randomly selected and examined on the center tree within each replicate using a 10X handlens. All live CRM (except eggs) were counted in two, 1-cm2 lensfields on partially shaded sides of each fruit. The two counts per fruit were combined and recorded as one observation. Data were subjected to log10(X + 1) transformations for statistical analysis and un-transformed means were presented for comparison. Cumulative mite-days and damage rating comparisons were subjected to Log10(X +1) transformations for statistical analysis and un-transformed means were presented for comparison.
