WebAbstract. Soon after the discovery of the potent herbicidal activity of certain classes of N -alkylated diamino- s -triazines, it was recognized that they act through interference with photosynthesis. Photosynthesis has been and is still the center of the interest of plant physiologists, biochemists, and agronomists. WebAtrazine acts as a selective herbicide that inhibits photosynthesis in susceptible plants. A selective herbicide is a herbicide where the target weeds are controlled, with little or no injury to the crop. Corn, sorghum, and certain other plants are not susceptible. They absorb and metabolize atrazine without experiencing its toxic effects.
