Abstract:
Susceptibility of Anti rrhinum majus, snapdragon, to Phytophthora cactorum stem rot (2) has encouraged the application of preventive fungicide solutions to the soil immediately after seedlings are trans planted.

Eight-week-old 'White Butterfly1 and 'Christina' snapdragon seedlings were transplanted from seed flats February 13, 1979, to 10 cm clay pots with a growing medium of silt loam, peatmoss, and perlite (1:2:2 by volume) amended to optimum nutrient levels and pH (3). The same day the growing medium was drenched with various fungicides at commercially used rates (1 ,k). Treatments were as follows:
