We examined some new fungicides for preventing tea diseases and obtained the following-re-sults.1. For the white spot disease, Dithane 1 500, 1 800 and ierlato 1 500 solutions were as effective as Bordeaux mixture. The effect of these fungicide dusts seemed to be inferior to that of the wettable powders of the same hind. Any fungicidal damage was not recognized on even younger buds. The spraying of Zerlate and Forinate gave the made tea an unpleasant smell, but others did not. Dithane spraying increased tea yield.2. For the Anthracnose, Dithane 1/400 solution, SANKIU Bordeaux, and Bordeaux mixture (0.4%) showed exceedingly and similarly powerful with one another, following these fungicides, the 1. 400 solutions of Zerlate and Fermate were shown effective. The effect of these fungicide dusts was inferior and their effective term was shorter than those of the wettable powders. Frequently, Zorlato and Fermate gave the made tea the fungicidal smell.3. For the Anthracnose, Phygone 1 300 and 1/600 solutions showed as powerful as Dithane 1 500 solution or Bordeaux mixture (0.4%).4. For the bacterial disease, Bordeaux mixture, SANKVO Bordeaux, and Dithane were recognized. their effect, but Zerlate was not.
