This year's starting out much heavier with forest tent caterpillars than
last year, as expected. Have done 2 sprays of BT (kurstaki). Works
amazingly well. They seem to prefer apples and plums over pears so far.
Last year my wife found a powder form of BT (by dipel) hoping what is left
over would last better than the liquid kind we can buy locally. I can
attest it does as I applied at the low dosage rate using year old powder ( 2
Tablespoon per gallon) in my solo sprayer. Next morning the ground was
littered with the bugs. First year I have used a Solo, very pleased, friend
got it for me at an auction for 5 bucks too, just sent off for the
adjustable tip. Took an hour, and 1.5 gallons to spray about 200 - 3 to
4 year old trees. Del
