Urglers,

A short while ago there was a question about boiling rhubarb leaves and
using the water to get rid of blackfly.

I suggested that if the oxalic acid in the leaves was thereby disolved in
the water, the water might indeed kill off blackfly.

I now think that the water will not kill the blackfly for the leaves of my
rhubarb are a home to many of the b - - - - - things!

But on the other hand, if the water used was boiling hot . . . . . . . .!!!

Regards

Ron
