effective against the Frostsapannerraupen, -VORSICHT - !!! - Never verwenden- for pear leaves die off. I have treated 2 years, fresh set of apple trees so because they had been stripped bare shortly after bud break, and I was afraid for their survival. The caterpillars have then made from the dust, although my fear was unfounded, exaggerated the trees again, and are now in good health. So if someone does not have to live off the fruit yield and can take a year crop losses in purchasing, he does not need to inject.
