Responses of Purple Nutsedge, Certain Weeds and Sugar Cane of Thiocarbamate Herbicides^*

Abstract

Soil incorporated herbicides, EPTC, vernolate and pebulate not only gave fairly good control of purple nutsedege, large crabgrass as well as certain broadleaved weeds but also persisted for a long time under the heavy rainfall. The activity was superior in the order of vernolate, EPTC and pebulate at the same dosage. Sugar cane, variety N: CO 310, was slightly damaged by the herbicides in both emergence and initial growth of shoot, but root elongation and rooting was not reduced but somewhat enhanced. Granular vernolate at 300g/ha in active ingredient is practicable for weeding in sugar cane with variety N: CO. 310.
