Fludioxonil, a low use rate seed treatment for the control of Fusarium on corn and potatoes

摘要

Fludioxonil has worldwide registration on major food crops such as cereals, corn, sorghum, potato, legume vegetables, and rice. It belongs to the phenylpyrrole class of chemistry and has a unique mode of action. Fludioxonil has demonstrated activityagainst several species of Fusarium that cause damping-off in corn, including F. moniliforme, F. graminearum, F. oxysporum, F. proliferatum, F. solani, and F. subglutinans. Laboratory studies with the listed Fusarium spp. show fludioxonil significantly increased seed germination by a mean of 52.1 percent compared to the standard captan. On inbred corn fludioxonil significantly increased field emergence compared to captan. Colonization of the seed was reduced by 43.9 percent, compared to captan. In trials on 9 varieties of potatoes fludioxonil showed suppression of the decay caused by Fusarium sambucinum on seed pieces, the level of suppression was superior to that given by thiophanate-methyl and mancozeb.
