Tomato and pepper were transplanted into pots
and watered as needed with a surface drip system.
One day before application of herbicides, the
irrigation system was turned off. To simulate
herbicide root uptake following heavy rains after a
dry period, each pot was placed in a plastic tub with
1 L of water and the appropriate herbicide rate. Pots
were left in the tub for 4 d with no additional
irrigation. After 4 d, the pots were removed from
the tubs and irrigated as needed throughout the
remainder of the experiment.
