The disease produces white to grey powdery growth on the upper surface of older leaves. The affected leaves curl, become chlorotic and die. In India since the last decade powdery mildew caused by Golovinomyces cichoracearum formerly called as Erysiphe cichoracearum has become one of the major diseases of sunflower. This disease causes considerable yield loss in various parts of the country.

    Wow. I did not know about the disease and it’s impact on sun flower growers. Would isolating the plant thatbis sick earlier help stop the spread of the spores. It would be fantastic tibtest how early in the progress of the disease can the spores be seen. This would enable early diagnostics with a foldscope.

    Do you have access to a farm where sunflowers grow? Would be wonderful to explore this further.

    Beautiful post – so amazing to read about all your ideas. Thanks for sharing with everyone.
