Control of Verticillium Wilt of Tomato Plants with ‘Cycocel’ ((2-Chloroethyl)trimethylammonium Chloride)

Abstract

IT is known that the severity of the wilt disease of tomato plants caused by Fusarium oxysporum f. lycopersici can be reduced by treating plants with one of a variety of growth regulating substances, such as indolyl-3-acetic acid, 2,4-dichlorophenoxyacetic acid, α-naphthaleneacetic acid and 2,3,5-triiodobenzoic acid1. We have found that, when applied to tomato plants in suitable concentrations, these substances also reduce the severity of the wilt disease caused by Verticillium albo-atrum, Rke. and Berth. Concentrations that were effective in this way also considerably altered the growth-form of the plant.
