Wouldn't it be better and easier to plant new fresh bushes bio Freak?
agood chance that you will move the sawfly too I think.
new varieties, clean bushes and clean soil is the way for me.
Bushes are weakened by an attack of sawfly and will prob not be great fruit bearing plants the next year.
i had sawfly last year on top of the bulflinches pecking the buds so my crop was poor. I intended a winter spray.....still time to do it......this year and I have already netted my bushes
