<pre>We are suffering badly from black sooty mould. I know this subject has
been discussed before but this may be a new slant on the problem.

I have a chalk that was obtained in China for repelling insects. It
works great on ants. Initially they don't seem to take much notice but
after about 1/2 an hour there is no sign of ants.
I tried it on the trunk of a few trees where ants were scurrying up the
tree. I put a line of this chalk around the trunk. A little later no
sign of ants.

I would like to develop a spray of some sort to spread the chalk onto a
number of trrees to see if it continues to repel the little b"s.

Anyone got any ideas. The medium for the liquid would have to be
something which did not cover the chalk with a coating as that might
smother the effect. But it needs to be something which would stick the
chalk to the trunk. If this works it could be a boon to the industry.
