Blueberry Rust and Thrips

Rust

I am seeing rust sporulation on last year’s leaves on Southern Highbush Blueberries. This indicates it will be a long season of rust control if we consider that we need to protect leaves until next fall. Given that we already have green fruit this year, your options for good rust control pre-harvest will be limited to Proline (7 day PHI), Quash(7 day PHI) and Abound (0 day PHI).

Thrips

Thrips are active this year. On fields I visited last week thrips numbers were less than 1 per bloom. With temperatures in the 70’s and 80’s for the next 15 days, numbers are likely to escalate.
