α-Substituted benzylamino-s-triazines were synthesized, and their phytotoxic activity and phytotoxic symptom against paddy weeds and transplanted rice seedlings were evaluated. Some of these compounds exhibited potent phytotoxicity against the weeds, high selectivity between the rice and the weeds, and had different phytotoxic properties to atrazine and simetryn. Among these compounds, 2-chloro-4-ethylamino-6-α-methylbenzylamino-s-triazine (2), 2-chloro-4-ethylamino6-α-ethylbenzylamino-s-triazine (3), 2-chloro-4-diethylamino-6-α-methylbenzylamino-s-triazine (17), and 2-chloro-4-diisopropylamino-6-α-methylbenzylamino-s-triazine (19) were found to have high phytotoxic activity and selectivity. The phytotoxic symptom of these compounds was mainly growth inhibition to the weeds. Two of these, the diethylamino (17) and diisopropylamino (19) compounds, showed growth inhibition activity without burning the leaf of rice plants at high doses.
