Moderate Drought Expands in Georgia but Minor Changes Elsewhere

By Pam Knox

The latest Drought Monitor, released this morning, shows that moderate (D1) drought has doubled in size in Georgia from last week’s map due to no rain over the last week. Since the cutoff of this map, we have received 0.5 to 2.0 inches so some of this may be cut back on next week’s map, especially since more rain is expected in the next week. Elsewhere in the region there were only minor changes in the drought status from last week, including Puerto Rico.

White rot, also known as sclerotinia, is a common agricultural fungal disease caused by various virulent species of Sclerotinia. It initially affects the root system (mycelium) before spreading to the aerial parts through the dissemination of spores.

Sclerotinia is undoubtedly a disease of major economic importance, and very damaging in the event of a heavy attack.

All these attacks come from the primary inoculum stored in the soil: sclerotia. These forms of resistance can survive in the soil for over 10 years, maintaining constant contamination of susceptible host crops, causing symptoms on the crop and replenishing the soil inoculum with new sclerotia.
