Who Am I?

Powdery mildew will not kill its host quickly, and fruits are not affected. Powdery mildew produces white powder-like spots that cover the upper side rather than the underside of the leaflets. With time, the dense, white mycelial network colonizes the upper surface of the leaves.

Powdery mildews favor warm and dry climates. The fungi does not need the presence of water on the leaf surface for infection to occur. However, spores need dew to germinate and can be carried by the wind.

Caution and careful notice should be taken when using any plant protection products (insecticides, fungicides, and herbicides). It is the grower’s sole responsibility to keep track of the legal uses and permissions with respect to the laws in their country and destination markets. Always read the instructions written on labels, and in a case of contradiction, work in accordance to the product label. Keep in mind that information written on the label usually applies to local markets. Pest control products intended for organic farming are generally considered to be less effective in comparison to conventional products. When dealing with organic, biologic, and to some extent a small number of conventional chemical products, a complete eradication of a pest or disease will often require several iterations of a specific treatment or combination of treatments.
