LORSBAN POSTBLOOM USE FOR APPLE BORERS APPROVED

LORSBAN LABEL REVIEW

With all the back-and-forth regarding the registration status of the different Lorsban formulations this season, a number of people have expressed a bit of confusion over what is labeled for which use, and we have to admit that keeping up with the status here in NY (which always follows its own calendar) has been something of a challenge. According to the most recent information we've been able to gather, the following represents some of the specifics for use of this product on tree fruits. Please refer to the label for complete details.
