I'm devastated, the last red spider mite systemic insecticide known to me
has been discontinued. So how does the group deal with RSM.

Stick the plant out in the rain for a few months, and, if that doesn't
work, throw it away. I long since lost the battle. I suppose growing the
same individual plants for 15-45 years all together in the same
greenhouse is asking for trouble.

I'm wondering about using the biological control in the greenhouse.
