Raspberry Beetle

Postby Nimrod103 » July 2nd, 2018, 10:02 am

Any suggestions how to combat this pest, which I get every year, mainly on summer fruiting raspberries? The karimone water traps seem to be very expensive, while all the insecticides say 28 days before harvest minimum, yet for raspberries, spray at the first fruit turning pink, which is a lot less than 28 days. I am really stuck on this one.

Apparently not all of them...
