11th Monilinia Update

Friday, May 20, 2016

All monitored sites in Nova Scotia, including Cape Breton are above the 40% F2 stage or will be by the end of today.

Cape Breton sites reporting:

Skye Mtn. - 46% F2
Keppoch - 42% F2
Bornish - 39.7% F2

We are still seeing active cups throughout central and eastern Nova Scotia so growers should still be protecting their buds according to infection periods.

Westchester (Kennel field) - 7 mature, 1 drying up
Higgins Mtn - 2 nearly mature, 3 mature, 1 drying up
Pigeon Hill - 2 pins, 1 nearly mature, 1 mature
Parrsboro (Airport) - 2 drying up
Harrison Settlement - 3 mature, 2 pins
Advocate - 1 mature
Mt. Pleasant - 5 mature, 3 drying up
Glasgow Mtn. - 1 mature
Amherst area - still seeing mature cups

The risk in central Nova Scotia is still high to moderate, although it is decreasing.  If fields were treated this week with Proline or Propiconazole based products (Tilt, Topas, Jade, bumper etc.) your fruit and vegetative buds should be protected well into next week.  This should get you through the Monilinia season.  The exception to this might be very late coastal fields (advocate) or interior high ground fields which still may have pressure next week.

If it has been over a week since your last application, and your plants have advanced you should consider protecting your fields, particularly for your mid-season and later developing fields.  For Proline to work well it needs to be applied before the infection period. Propiconazole based products can still be applied after the infection period and achieve good control.

We did see some scattered showers overnight and into the morning throughout central NS. Depending on the rain received in your area it may have been enough for an infection period.

The next update will be late in the day on Tuesday, May 24th.
