THE BLACK WATTLE BIOCONTROL AGENT:
Dasineura rubiformis
The release time for Dasineura rubiformis starts NOW !!! (July 2015)

It’s a midge that prevents black wattle from setting seed. It has taken off like a rocket in release sites and is fast becoming one of the most important aspects of black wattle control.
It would be great if we could get the midge firmly established in the Southern Cape so please come and pick up some galls from the GRBG nursery. They will be delivered every Monday and Wednesday for the next 3 weeks. It’s easy to release (see instructions plus other info attached) and so effective it really is a crime NOT to do it.
And it is FREE !!!!


Instructions
RELEASE OF WATTLE BIOCONTROL AGENT
