Abstract
Weed management in tomato (Solanum lycopersicum L.) continues to be a challenge for vegetable growers in Ohio. Field experiments were conducted at the North Central Agricultural Research Station in Fremont, OH in 2009 and 2010 to evaluate the tolerance of tomato to fomesafen and the efficacy of this herbicides on weed control. The crop was machine-transplanted in June 5, 2009 and June 3, 2010. The experimental design was a randomized complete block with 4 replications. Pre-transplant treatments were applied on June 4, 2009, and May 27, 2010 and included fomesafen at 280, 350, 420, 560, and 840 g ai ha-1. Crop injury and weed control were assessed visually using a linear scale in which 0 indicated no crop injury or weed control, and 100 indicated death of crop or total weed control. Plots were evaluated at 7, 14, 28, and 42 day after treatment. The crop was harvested on September 16, 2009 and September 30, 2010 and total yield per plot was determined. Minimal crop injury was observed 7 and 14 DAT in plots treated with fomesafen at 840 g ai ha-1 both years. However none of the treatments caused crop injury either years at 42 DAT. Fomesafen at the highest rate provided acceptable annual grass, common purslane, and redroot pigweed control 42 DAT. Fomesafen application did not reduce total tomato yield. Registration of fomesafen herbicide would provide tomato growers an opportunity to control weeds caused by late emergence or poor initial control following a burndown herbicide application in tomato.
