 | How many days of protection does this provide? 2 weeks has been mentioned for the length of protection for a Fungicide application.
 Never have tried Fungicide between greenup and jointing.
 The only times that I have used a Fungicide for flag-leaf protection have been rescue treatments.
 Typically these were later than ideal.
 In situations like this forecast, it is tempting to just apply something now and again in 2 weeks.
 Eliminating the question about exact timing.
 
 I suppose that the next question should be,
 How many days between,
 A flag leaf protection application,
 And
 A head protection application.
