Integrated control program of powdery mildew on mango trees in Egypt by foliar sprays of fungicides combined with fertilizers [electronic resource]

Includes bibliographic reference.

The powdery mildew of mango caused by Oidium mangiferae has become a serious and
widespread problem in many parts of Egypt. A field experiment was conducted for four seasons
2019-2022 to investigate the efficacy of four fungicides, COBOX 50% WP (Copper Oxchloride),
TOPAS 10% EC (Penconazole), PUNCH 40%EC (flusilazole and Carbendazim) and
KEMAZED 50%WP (Carbendazim) along with control (water spray) against mango powdery
mildew on the most popular cv. Taimour. Each fungicide was sprayed in 15-d-intervals with di potassium phosphate,
mono-potassium phosphate, and calcium phosphate alone in one season in
2019 at two governorates (Aldaqahlia and Domietta). Under ALmansoura condition, the best
treatment was TOPAS, which recorded 15.75 and 26.25% disease severity compared with control
which recorded 67.5 and 74.25% disease severity on the leaves and blooms, respectively. The
integrated control program combined the fertilizers with fungicides in three successive seasons
2020,2021 and 2022. This program was decreasing the disease and also was decreasing the
number of sprays fungicides so this study gained eco-friendly methods to control a serious
disease and cost saving and the most important is decreeing the residual effect of pesticides in
fruits.
