“…This herbicide injured potato plants when applied POST at 0.22 lb/ha in our preliminary study and has been labeled for emergency use for volunteer potato control in corn. Triclopyr injured potato when applied at rates greater than 100 g/ ha (Lobb 1989), suggesting possible options within corn. Cultivation can control volunteer potato plants, but three or four cultivations are required to eliminate them (R. A. Boydston, unpublished data).…”

Volunteer potato plants are difficult to control in rotational crops, and they harbor harmful diseases, nematodes, and insects. Five herbicide treatments were evaluated for control of volunteer potato in field corn grown under no-till and conventional tillage in 1994 and 1995. In mid-June, potato control was greater in conventionally tilled corn than no-till corn primarily due to the reservoir tillage that followed postemergence (POST) herbicide applications in the conventional system. Final potato tuber weight was not different between tillage levels in 1994 or 1995. Herbicide treatments reduced potato tuber weight 64 to 96% in no-till corn and 85 to 99% in conventionally tilled corn compared to nontreated checks. Atrazine applied preemergence at 1.1 kg ai/ha followed by dicamba plus 2,4-D applied POST at 0.28 plus 1.1 kg ae/ha, respectively, reduced potato tuber weight greater than 95% in both years and both tillage systems. Corn yield was not affected by tillage level or herbicide treatments in 1994 or 1995 and averaged 10.5 MT/ha in 1994 and 15.1 MT/ha in 1995. In a separate experiment, glyphosate, dicamba plus 2,4-D, or fluroxypyr applied at the eight-leaf stage to potato grown without a corn crop, and followed by cultivation 10 d later, reduced the number of potato tubers produced 79 to 95% compared to nontreated potato.

“…Lucus and Lobb (1987) found that yield reductions occurred when clopyralid was applied at 1000 g ai/ha, but visual symptoms occurred with rates as low as 10 g ai/ha in field grown tomatoes. Lobb (1989) reported, again for field grown tomatoes, that 50 g ai/ha of triclopyr caused significant visual effects and yield reductions. Glyphosate produced yield reductions at 500 g ai/ha and visual symptoms at 50 g ai/ha and metsulfuron significant yield reduction and visual symptoms at 0.1 g ai/ha.…”

No Observable Effect Levels were determined for four commonly used forestry herbicides on glasshouse grown tomatoes. For metsulfuron and glyphosate, NOELs based on visual symptoms were lower than those for dry weight production (ED5). For triclopyr the values were similar. The rates used for clopyralid/picloram mixtures allowed for a visual NOEL to be determined but were too high for the determination based on dry weight. The value of the NOEL varies with the method used to determine it.
