Selectivity and effectiveness of Kapina® and Kapina Plus® herbicides controlling Cyperus sp. in Zoysia japonica and Cynodon dactylon grasses
The use of herbicides in turf grasses is a promising technique, since required precautions regarding the selectivity. In order to evaluate the selectivity and effectiveness of Kapina® and Kapina Plus® herbicides in controlling Cyperus flavus and Cyperus rotundus in Zoysia japonica and Cynodon dactylon, two experiments were conducted in green house conditions. Applications were performed with a CO2 pressurized spray, using application fee of 250 L ha-1. Kapina® e Kapina Plus® herbicides, from 750 mL ha-1, showed excellent control of C. flavus and C. rotundus; as well as satisfactory selectivity for Zoysia japonica and Cynodon dactylon grasses. Kapina Plus®, from 750.0 mL ha-1, besides herbicide action, also presented viability as regulator of vegetative and development growth of Emerald grass.
