Abstract
In 1967 the authors reported apparent antagonistic action of ozone and 2,4-D when used as air pollutants. Continued work has shown several horticultural plants like zinnia, tomato, and elm survive otherwise lethal dosages of 2,4-D when exposed to otherwise damaging concentrations of O/sub 3/ simultaneously or shortly before or after exposure of plants to 2,4-D.
