title: The cell-wall phosphatase of cotton (Gossypium) is inhibited by kelthane.
abstract: Kelthane [4,4'-dichloro-alpha-(trichloromethyl)benzhydrol] was previously shown to decrease the limited tolerance of susceptible varieties of cotton (Gossypium) to Verticillium wilt. Kelthane was shown in the present study to inhibit the cell-wall p-nitrophenyl phosphatase of cotton. In view of information already establishing the cell wall as a primary site of action of Verticillium wilt, the data are interpreted as suggesting an as yet undefined interaction between Kelthane, cell-wall phosphatase and verticillium-resistance mechanisms of the cell wall.
