Triazine Tolerant

Triazine Tolerant (TT) canola was the first herbicide tolerant type in Australia and has been consistently adopted by growers for its high yield potential, blackleg resistance and excellent weed control. TT canola is tolerant to the triazine herbicides: atrazine (ATR), simazine (SIM), propazine (PRO) and terbuthylazine (TBA).
