| This table estimates
fungicide intervals for suppressing spread of secondary scab. Use the appropriate primary
scab respray guidelines instead of this table
until ascospore releases are completed.
Rules used to estimate protection depletion are described on the
Background Information page (see link above).
Green text and yellow background indicates dates after final primary scab control sprays until the date scab control can be confirmed by scouting for presence of 2nd generation scab lesions. |
|||||
| Brown text with grey background indicates dates when 2nd generation scab lesions from the
final ascospore release have had time to begin appearing. By this point, growers will have had
opportunity to confirm the status of primary scab control. Estimates for these dates are provided only
for those situations where scab control has not been successful, and there
are enough active scab infections present to cause an unacceptable risk of
fruit scab infection. In that case,
fungicide protection is needed for at least 4 weeks until active scab lesions
exhaust their supply of spores. Depending on scab severity, market sensitivity, temperatures, rain frequency, and proximity to harvest; shorter or longer fungicide intervals to suppress spread from active scab lesions may be more appropriate than the estimates shown below. |

| The estimated date for 95+% scab ascsopore release at this site is: May 8. The estimated McIntosh fruit set date for this site is May 5. The approximate terminal bud set date for this site is June 22. | |||||
