Re: Fwd: [PW] PA BLACK FLY PROGRAM-HELP!



Hi Laura,
Cornell indicates that Bt var israelensis  is likely the form used but
suggests that traditional standing water control and weed removal is
more effective. Aerial spraying of Bt is undesirable as for example in
Seattle and Vancouver were children were sprayed in school yards leading
to allergy and wound infection. Joe

Bt variety israelensis is marketed for use against black flies and
mosquitoes, fungus gnats, although unless used on a community-wide
basis, it is probably more effective to eliminate standing water and
control weeds at the edges of ponds.

Hi!
What does anyone know about this Bacillus thuringiensis insecticide that
the DEP says is derived from natuirally occuring soil bacteria to be
used against black flies? I need info soon as tomorrow morning York Co.
Commissioners are to decide if they will go into the program for next
year at the turn of $40,000. and matched with the state's $120,000!!
This is not the Nile Virus,just to get rid of pesky flies that can
"sometimes drive people indoors"!!!!

According to the newspaper article,Lancaster and Dauphin Co. have
already o.k.'d it.

Yours In Sludge (of all kinds)!
Sandy
