IPM: 2007 Fire Blight Data

Maryblyt and Cougarblight Fireblight Predictions: Below is data generated from Maryblyt and Cougarblight using the weather data collected from the weather station out the east side of the county. Only the previous seven days of generated data plus four predicted days in red are presented from Maryblyt, and the previous three days of data, plus a predicted day in red is presented from Cougarblight.

Stage: AG= Apple Green tip; B= Bloom; PF= Petal Fall

Min/Max Temp: Minimum and Maximum Daily Temperatures

Precip: May be in the form of rain or a heavy dew. If there was a heavy dew, precip will equal .01".

Spray?: Did we elect to spray an antibiotic

EIP: Epiphytic Infection Potential-An index for infection risk given in the Maryblyt program. If EIP is <100 few, if any infections are likely to occur; an EIP of 100-150 is low, but may support an epidemic of blossom blight; an EIP of 200-250 indicates that large numbers of infections are likely should a wetting event occur,

Risk: Risk assessment given by Maryblyt (Low, Medium, High, Infection)

Cougarblight: Only predicts risk of infection when apple trees are in bloom.

If an entry is in red, then it is a prediction of what the infection risk should be given the predicted high temperature and risk for rain.

L=Low Risk of Infection

M=Marginal Risk of Infection

H=High Risk of Infection

E=Exterme Risk of Infection
