FORECAST SUMMARY: Wednesday, June 20:
*** Disease Update: 20 June *** John Yocum in PA reports numerous infections in plant beds in Lancaster and Chester counties. These are actively sporulating. There are few new field infections due to recent unfavorable weather. Bill Nesmith in KY also informs us that disease activity has increased (from the previous very low levels) in east-central KY.
*** With our new reports from the central NC mountains (Madison County) and southwest Ohio (Brown County), we are dropping the southern TX location from the regular forecasts. The new sites are being added.
*** A frontal system will affect the eastern U.S. during the middle and late parts of this week. The Ohio Valley, upper mid-Atlantic, and southern Appalachian Mountain regions are the main areas affected Wednesday and Thursday. In the Ohio Valley.... there is Moderate Risk Wednesday for east-central and eastern KY, southern OH, and western WV. These same areas face Strongly Moderate Risk on Thursday as conditions become more favorable. In the upper mid-Atlantic.... solar exposure should squelch any long-range transport on Wednesday, with Low Risk for southern PA. Conditions will become quite favorable on Thursday, however. HIGH RISK for southern PA growing areas on Thursday. In the southern Appalachian Mountains.... mixed conditions will dominate both days. Moderate Risk on Wednesday for the central and southern mountains of NC, extreme northeast GA, and extreme northwest SC. Low Risk elsewhere. Moderate Risk on Thursday for the central and northern NC mountains, and southwest VA. In the lower mid-Atlantic states... conditions are unfavorable for disease development both Wednesday and Thursday, with Low Risk for the central and eastern portions of NC and VA. To the south.... mixed conditions prevail in southern GA and northern FL each day. Moderate Risk in this region Wednesday and Thursday.
*** We strongly encourage growers to monitor their plants for signs of disease. Diligent scouting and prompt reporting of blue mold are essential if one wishes to derive maximum benefit from the services we provide. ***

***** NOTE: These forecasts/outlooks only apply to disease development from airborne transport of spores!!! We do not have the capability to ascertain blue mold development by other means, such as transplanting of infected seedlings, nor will we attempt to do so.
