Triazine resistance, however, is by far the most serious weed resistance problem for farmers in the northeastern United States. ... A biotype is a population of plants within the same species that have in common specific traits such as resistance to the triazine herbicides.

What is triazine used for?

Triazines are selective herbicides used to control a wide spectrum of grass and broadleaf weeds in cereal, oilseed, and horticultural crops. Triazine herbicides kill weeds by interfering with the electron transport chain in photosystem II (PS II).

How does triazine affect photosynthesis?

s-triazine herbicides act by inhibiting primary events in photosynthesis in the chloroplast: binding to the D-1 protein in photosynthetic electron transport. This binding stops photosynthesis.
