Application of mixture of CAT, Atrazine to turfgrass

—Mainly herbicidal effect to Perennial weed (Oxalis corniculata L.) on turfgrass—

Abstract

The tests and applications of herbicides CAT (2-chloro-4, 6-bis (ethylamino) -striazine) and Atrazine (2-chloro-4-ethylamino-6-isopro-pylamino-1, 3, 5, -triazine) to tnrfgrass have been carried out for years.
The mixture of CAT and Atrazine clearly showed remarkable effectiviness and similar synergistic action to perennial weed (Oxalis corniculata L.) . No injury was given to turf-grass (Zoysia matrella M.) in greenhouse test. Also in field test, both herbicidal activity and selectivity were excellent as same as in greenhouse test.
In conclusion, it was considered that the mixture of CAT and Atrazine can apply excellently to tnrfgrass.
