What is the difference, in appearance, between downy mildew and powdery mildew?

Downy and powdery mildew are very similar, causing a fuzzy white or purple covering on leaves, flowers and stems. Downy mildew tends to grow on leaf undersides while powdery mildew appears on upper surfaces of leaves and on flowers. Sometimes powdery mildew causes red or purple discoloration in affected leaves.

Upper surfaces of leaves with downy mildew become pale, show angular yellow spots and sometimes wilt. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
