Abstract
Detached barley leaves treated with the systemic fungicide, 2,3-dihydro-5-carboxanilido-6-methyl-1,4,oxathiin (Vitavax), remained green longer than nontreated leaves. The chlorophyll content of treated leaves was slightly higher than that of nontreated ones during the first 7 days, and markedly higher 20 days after treatment. The immediate effect of the chemical was inhibition of photosynthesis and respiration. Treated leaves returned to apparently normal photosynthesis and respiration within 5 days; however, their mg dry weight/g fresh weight ratio remained lower than that of nontreated leaves, even 20 days after treatment.Keywords
