Abstract

Water lettuce (Pistia stratiotes L.) was susceptible to applications of 6,7-dihydrodipyrido(1,2-a:2’,1′-c)pyrazidiinium salt (diquat). The most satisfactory rates of application were 1.0 to 1.5 lb/A of diquat. The addition of a surfactant did not increase the effectiveness of diquat. Several other chemicals gave unsatisfactory control of water lettuce.
