| Abstract | ||
| The results showed that spraying potato plants with salicylic acid 1% before the occurrence of systemic symptoms after vaccination by Potato Virus Y, gives the best results to control the virus and severity of infection , that led to retard symptoms occurrence to 15-20 days of vaccination. The spraying also improves plant properties particularly its lengths reached 47.05 cm , 145.3 gm ,25.8 gm , 48.8 gm respectively, compared with infected plants which were 25.7 cm , 37.4 gm , 5.39 gm 20.64 gm respectively. While spraying with acid after symptoms occurrence gaves negative results to control the virus. The results showed that spraying by salicylic acid 1% and fertilization by mineral fertilizer (Multfer 5%) gives positive results to control the disease , mitigate its effect on plants and improve its properties. So its lengths reached 57cm , 240.9gm ,35.7gm ,40.1gm respectively. Compared with 27.7cm , 33gm , 5.1gm ,21.7gm respectively. For the same properties of infected plants . | ||
