Herbicide and mulch evaluations for weed management in west central Florida strawberries

James P. Gilreath, Bielinski M. Santos, Timothy N. Motis


Two trials were conducted to evaluate the effects of herbicide and mulch combinations on weed management and strawberry (Fragaria × ananassa Duch.) yields under field conditions. Treatments were established in a split-plot design with five replications. Herbicides were the main plots and mulch types the subplots. The herbicides napropamide at rates of 4.50, 6.75 or 9.00 kg·ha [sup-]; oxyfluorfen at 0.57 kg·ha[sup-] ; and napropamide + oxyfluorfen at 4.50 + 0.57 kg;ha[sup-] were applied pretransplant on pressed beds covered with either low-density polyethylene mulch or virtually impermeable film. Weedy controls were also included. Ranked weed counts were analyzed by using a Kruskal-Wallis test (P = 0.05) and fruit numbers and weights were examined with analysis of variance. Means were separated with a Fisher's protected LSD test at 5% significance. Results indicate that mulch types had no influence on weed counts and yields, whereas herbicides affected both variables. No significant herbicide by mulch interactions were found. The napropamide + oxyfluorfen treatment resulted in the highest fruit numbers and weights. This herbicide combination showed the best grass and broadleaf weed control.
