An additional trial was conducted to evaluate a sequential treatment of metribuzin and fluazifop for multiple weed species control in tomatoes. In the first two trials, both quizalofop and fluazifop provided an excellent control of grass species <em>Echinochloa colona, Digitaria sanguinalis, Eleusine indica,</em> and <em>Leptochloa filiformis</em>. These weeds were controlled with quizalofop at 0.112 and 0.224 kg ai/ha and with fluazifop at 0.28 and 0.56 kg ai/ha. None of the herbicides produced any apparent injury to peppers and tomatoes. The sequential treatment of metribuzin and fluazifop, 15 days later at 0.56 kg ai/ha, was highly effective against both grass and broadleaf weeds in tomatoes. This treatment caused no apparent injury.}, number={3}, journal={The Journal of Agriculture of the University of Puerto Rico}, author={Liu, Li C. and Goyal, Megh R.}, year={1989}, month={Jul.}, pages={231–237} }
