Hold Off on Second White Mold Sprays in South Carolina

From Tony Keinath, Clemson Extension Plant Pathologist Last week, I advised South Carolina brassica growers to spray brassica crops to protect them from white mold, based on symptoms seen on kale and stock, a brassica winter annual, in Charleston. The initial symptoms were triggered by the cold temperatures of Dec. 16 and 17 that completed…

Considerations for Upcoming Winter Weather

Question of the Week – Spanish Moss

What year did the Spanish introduce Spanish moss to North America? This week’s question was a trick, as Spanish moss is neither Spanish nor a moss. Spanish moss (Tillandsia usneoides) is a flowering epiphyte (a plant that grows on another plant, but is not parasitic) that is native to the Southeastern US and parts of…

Spray Strategies for Strawberry Disease Control in South Carolina

Guido Schnabel, Extension Plant Pathologist Disease management is essential for growing high-quality strawberries in plasticulture. While Botrytis fruit rot (BFR) is a disease you can expect every year, Anthracnose fruit rot (AFR) and the more recently introduced Neopestalotiopsis fruit and crown rot (Neo-P) may or may not appear (Fig. 1).

Question of the Week – Yellowmargined Leaf Beetle

What is this critter hanging out on sweet alyssum? This is an adult yellowmargined leaf beetle (YMLB), which is well-known (notorious?) to many of our smaller and low-input brassica farmers, as it is very difficult to manage without conventional insecticides. It is a specialist herbivore of plants in the Brassicacea family and is a key…

Question of the Week – Scurf

What is going on with the skin of this sweetpotato? This sweetpotato has a superficial disease known as scurf (Monilochaetes infuscans). Scurf develops on the skin of the sweetpotato and is not visible on the flesh after peeling the skin. Though infected sweetpotatoes are still perfectly edible, this cosmetic defect renders them unmarketable. Scurf development…
