- ABSTRAK Results of an experiment to control mosses in tea with glyphosate (isopropylamino salt of N. phosphonomethyl glycine), DNOC (Dinitro-ortho Cresol), fentin acetate (triphenyl tin acetate) and manual scraping. after pruning, showed that at 6 weeks after treatment, the damage rating caused by DNOC � 0,2% com. prod. (commercial product) and fentin acetate 0,2% com. prod. could match manual scraping, while glyphosate � 0,5% com.prod. could not equalize the three treatments mentioned before. Based on rates of regeneration of mosses on the tea trunk at 6 and 12 months after treatment, DNOC was the best chemical in suppressing regeneration, followed by fentin acetate and then glyphosate. All three chemical treatments were far better than manual scraping in this respect, up till the 12th month. The glyphosate treatment had a clear suppressing effect on the emergence of primary shoots up till the 4 th week after pruning as compared with the other chemical treatments and the control, but its suppressing effect is still significantly less then manual scraping. At 8 weeks after pruning the difference of number of primary shoots among the treatments became less and at the 12th week, there was no sifnificant difference among the treatments. The total production of picked tea of 10 pluckings from the glyphosate treated tea bushes was not significantly different from the manually treated tea bushes, but they were significantly less than the other treatments. The cumulative yield of 20 pluckings showed that these differences were aleviated and only the DNOC treated bushes showed a tendency to produce higher then the others. DNOC and fentin acetate had a better killing effect on the mosses and also suppressed its regeneration better than glyphosate. Compared to manual scraping, glyphosate could be used in controling, mosses in tea without too much harm on the primary shoot formation and picked tea production and it bad a better suppressing effect on moss regeneration. Further experimentation should be conducted. Key words: lumut, semprotan glifosat, perdu teh
