Abstract

Terbacil at 0, 0.28, 0.56, 0.84, and 1.12 kg·ha−1 was applied immediately after planting to strawberry (Fragaria xananassa Duch.) cultivars Surecrop, Honeoye, Guardian, Redchief, and Delite. Plant vigor and number of mother plants were reduced by all herbicide rates >0.28 kg·ha−1. ‘Delite’ plants were less vigorous at the time of planting than other cultivars. There were no differences between cultivars in number of rooted runners, but terbacil at rates >0.28 kg·ha−1 reduced runner rooting. Yield the year following planting was dependent on terbacil rate and cultivar. Vigorous cultivars (i.e., ‘Redchief) had superior yields. Terbacil at 0.28 kg·ha−1 was safe when applied to newly planted strawberries on soils with organic matter content of at least 1.0%. Chemical name used: 5-chloro-3-(l,l-dimethylethyl)-6-methyl-2,4(1H,3H)-pyrimidinedione (terbacil).
