Efficacy of Miticides for Late-season Control of Twospotted Spider Mite in Strawberry, 2013–2014

The efficacies of Nealta and SuffOil-X were evaluated by comparison to Acramite (a grower standard) and a nontreated check for TSM control at the Gulf Coast Research and Education Center, Wimauma, FL, in the winter–spring of 2014. “Strawberry Festival” transplants were set in the field on 8 October 2013 in plastic mulched beds, 13 inches high and 27 inches across the top, and with 4-ft bed spacing. Overhead irrigation was applied for 14 d after setting to aid in establishment of the transplants. Trickle irrigation was used for the remainder of the experiment. Plots were infested from a laboratory colony reared on lima bean with 50–100 motile TSM per plant on 26 March. The presence of predatory mites among the plots suppressed TSM …
