Controlling white mold in in lettuce
In cool, wet soils, the fungus will infect the host and produce the characteristic white fungal growth on stems of infected plants, eventually black sclerotia will develop. Control of white mold begins with preventative fungicide applications soon after transplanting.
For lettuce: Apply one of the following fungicides at transplanting and/or thinning (see labels for instruction): Cannonball (fludioxonil, 12) at 7.0 oz. 40WP/A; iprodione at 1.5 to 2.0 lb 50WP/A (2 applications per season allowed); Endura (boscalid, 7) at 8.0 to 11.0 oz. 70WP/A (suppression only, 2 applications only); Quadris (azoxystrobin, 11) at 0.40 to 0.80 fl oz./100 0 ft row 2.08F.
