FIG. 1.
Relationship between the ratio of zones of inhibition and the number of carbons in the tri-n-alkyltin chlorides and the concentrations of tri-n-alkyltin chlorides. The ratio is defined as the zone of inhibition with JW436 divided by the zone of inhibition with RW2802. The solid curve (○) is for zones of inhibition at the lowest concentration and the broken curve (●) is for zones of inhibition at the highest concentration of tri-n-alkyltin chlorides.
