Alert at three rates per acre was compared with Alert at the same rates tank-mixed with FC 435-66 petroleum oil only or with petroleum oil and one of two copper formulations against CRM. Treatments were assigned to 3 X 3 (= 9 tree) plots in a RCB design, replicated 5 times on 8-10 ft tall trees with 18 X 26 ft spacing. Treatments were applied on 24 Jul using an FMC 352-S PTO airblast sprayer with speed, nozzling and pressure adjusted to deliver the designated gpa. At each evaluation date, 20 fruit were randomly selected and examined on the center tree within each replicate using a 10 X handlens. All live CRM (except eggs) were counted in two, 1 -cm2 lens field 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) transformation for statistical analysis and untransformed means are presented in the table for comparison.
