Abstract

Additional fertilization with actosol macroelements, actosol microelements and/or compost; significantly reduced the incidence of onion downy mildew disease(ODM) on both tested onion cultivars (Giza 6 and Giza 20). Increasing the fertilizer dose gave more disease reduction and improved growth characteristics, photosynthetic pigments, water relations and yield production. Generally, the best results were obtained when actosol macroelements (10 ml/l) was applied. Application of plant water extracts on onion plants at intervals of 15 days, significantly decreased the infection with the fungus. Both of neem or mint plant extracts at conc. 10 % showed the best results for disease reduction, growth characteristics, photosynthetic pigments, water relations and yield production. The best yield production was obtained by the application of actosol macroelements and /or neem plant extract.
