Monilinia Blight Update for May 31st

Tuesday, May 31, 2011

Special Notes:
• Grower co-operators in various areas of the province monitor flower bud development, apothecial cup development, as well as keep track of temperature and flower bud wetness.
• The decision to control Monilinia Blight is dependent on past history of the disease in a particular field.
• Flower buds become susceptible to Monilinia Blight at the F2 stage (bud scales separating).
• Once fields reach 40-50% F2 and beyond, a fungicide is required within 72 hours of the start of an infection period.
• This application will provide 7-10 days protection.
• Refer to Monilinia factsheets for pictures of the F2 stage and temperature and wetness requirements for an infection period.

Most of Cape Breton is above the critical 40-50% F2 stage. Given the current forecast, risk for infection in Cape Breton is going to be low as we are nearing the end of the infection period in this area of the province.

Stay tuned on Friday for information regarding botrytis!

Growers should be looking at sprout fields for spring leaf-feeding insects (span worm and flea beetle)!
