White Mold

Figure 1 - Circular, light tan colored apothecia 2–10 mm diameter (1⁄8 to 1/4 inch) develop from black sclerotia buried to a depth of 5 cm (2 inches) and release ascospores.

Figure 2 - Ascospores colonize blossoms and other senescent plant tissue beneath and within the canopy; infected plant stems, branches and vines become watersoaked and wilted.

Figure 3 - Affected tissues become covered by white, cottony mycelia and sclerotia which darken and harden with age. Tissues dry out and bleach to a nearly white color; the epidermis easily sloughs off when rubbed.

Also affects sunflower, potato, canola and most weeds.
