1 Precautions apply to conventional, Clearfield IT (imidazolinone-tolerant), Liberty Link, Poast Protected, and Roundup
Ready hybrids because of potential adverse interactions (crop injury) between insecticides and herbicides. There is no
interaction between herbicides and any insecticide, regardless of application method, on Pioneer Clearfield IR
(imidazolinone-resistant) hybrids.
2 With Lightning, do not use Counter 15G on Clearfield IT hybrids.  Use Counter 20CR and Thimet only as banded
applications on Clearfield IT hybrids.
