We are getting into the heart of blight season for a good chunk of Nova Scotia. Many fields are at or are approaching 40-50% F2 stage in Central Nova Scotia. (especially by the end of the weekend). The exception to this would be higher elevation fields or traditionally late fields.
The weather for Sunday is 10-15 mm of rain. Given the forecasted temperatures, if this does play out, there will be an infection period.
The entire western end of the province is beyond the 40% F2 stage and growers should be treating fields based on wet periods. Remember (Topas, Tilt, Jade and Mission) will protect open buds for 7-10 days after application. These products will also give some back action after infection. If buds are tight when a product is applied, it will not be protected if it opens up soon after.
Here is the list of reporting sites from today
Fenwick -36% F2 (1 pin)
