Abstract:
The possibilities of weed control in tea fields by chemicals have been discussed. Trials with dalapon (2,2-dichloropropionic acid) at Coonoor Experimental Station of United Planter's Association of South India proved encouraging and a fairly satisfactory control of grasses was observed. Two applications of dalapon, each at 5.35 Kg./ha. or at 5. 35 and 4:5 Kg./ha. or at 5.35 and 3.36 Kg./ha. were reasonably effective in controlling the grass weeds. No phytotoxic symptom of the chemical was observed on the tea bushes. In a separate trial the value of seven weed killers in controlling broad leaf weeds was assessed. All the chemicals have had a good effect in the control of weeds. Cornox D and Kuron were very effective in the control of dicot weeds and Paraquat was useful against both dicot and monocot weeds. No phytotoxic symptom was observed on the tea bushes following the application of these weed killers.
