Here, the BT was sprayed by helicopters two weeks
ago. We received info by mail that this was going to take place.
I find the caterpillars on plants but nothing has
been touched. Some are still alive but weak. Only the cherry trees carrying the
original web are chewed. Some caterpillars are still in the web, but they
are small and not very active.
Other little worms, like the green one with dark
head that is found in a terminal leaves on apple trees does not seem to be
affected.

Look for at least 24 hours before they begin to die -
normally however they cease eating almost immediately upon
consumption. We have very active BT Kurstaki that was prepared in Feb
2000.

BT-kurstaki
BT-kurstaki....I found an old bottle of this my wife
had for cabbage moths, mixed up a 1:200 ratio and sprayed tent catapillars
last night. They are still happily a chewing this sunnny morn.
Does
anyone know the storage life of this stuff (liquid in brown bottle stored
in the dark)?
On the lable are punched some difficult to decipher
numbers, how to translate?
Has anyone experience with spraying tent
catapillars....how long should I expect this bacteria to take to do them
in? _________________________________________________________________ Get
