| Abstract: | Five chemical preparations, Salicylate, Viruside, Potassium oxalate, Sodium Phosphate, Sodium Hydrogen Phosphate were applied to papaya for control of Papaya Ringspot Virus Disease (PRSV). These preparations were found good for prevention against PRSV and had prevention efficiency of 71.67 %, 92.63 %, 83.72 %, 80.09 % and 76.21 % respectively on healthy plants. On infected plants Salicylate was the best in controlling PRSV, and reduced the incidence evidently. Compared with water treatment, these preparations produced obvious effect in preventing from and controlling the PRSV. |
