BAY SMY 1500 for Selective Control of Black Nightshade (Solanum nigrum) and Other Weeds in Tomato (Lycopersicon esculentum) Fields

Abstract

Black nightshade was selectively controlled along with other annual weeds in direct-seeded tomatoes by BAY SMY 1500 applied preemergence. BAY SMY 1500 was also found selective for transplanted tomatoes when applied prior to transplanting or soon after planting prior to black nightshade emergence. Black nightshade control and crop selectivity were obtained with BAY SMY 1500 at 0.75 and 1.25 kg ai ha-1applied on sandy loam and clay loam soils, respectively.
