Abstract: The quality and yield of the tea production were significantly improved after spraying TA-BR in combination with Bt. The yield could be increased by 6.76%~26.90%, the amino acids/tea polyphenols ratio was obviously reduced, while water extracted substances, the soluble sugar and vitamin C were higher than those of CK. In addition, the control effects of TA-BR in combination with Bt on the Euproctis pseudoconspersa ,Ectropis obliqua hypulina and Andraca bipunctata,which are the main tea pests,could reach above 90%, and this product is also safe for natural enemies.
