In fields naturally infested with Verticillium dahliae, metham-sodium at 400, 600 and 800 1/ha was applied to reduce the fungal population. Metham-sodium delayed and reduced disease incidence at all doses tested compared with the control; this effect was maximal at 800 1/ha. However, an optimal yield (maximum kg potato/liter metham-sodium) was obtained at 600 1/ha. © 1984, Springer Science + Business Media B.V.. All rights reserved.
