Scab and rust infection April 25-26

We recorded 12 hours of wetting at 53-62° at our AREC, Winchester April 25-26, an apple scab, quince rust and cedar-apple rust infection period. Where protection was not adequate, growers are advised to follow up with an SI fungicide to offset possible infection of blossoms, which are now very susceptible to quince rust. Extended wetting is likely tonight and during the next several days.
