ଲକ୍ଷଣ
Yellow spots appear on the upper leaf surface in early summer and the underside of the leaf displays yellowish blisters. Later, brownish-yellow fungal threads grow on the underside of the leaves. Unlike other fungi, they do not have the form of a film or layer, but are clearly elevated. At a final stage of infection with White Pine Blister Rust, leaves fall off.

ରାସାୟନିକ ନିୟନ୍ତ୍ରଣ
There are no fungicides available to treat the White Pine Blister Rust on currants and gooseberries.
ଏହାର କାରଣ କଣ
White Pine Blister Rust is not a serious disease for alternate hosts such as currants and gooseberries, but is a very serious disease for Pines. The fungal spores are transported by wind and can be carried over very long distances. Fungi generally prefer a warm, humid climate, so locations with good ventilation are needed to dry quickly after rainfall.
ସୁରକ୍ଷାତ୍ମକ ଉପାୟ
- Leave sufficient space between plants to ensure good ventilation.
- Don’t plant currants and gooseberries in close proximity to pine trees.
- Plant less vulnerable varieties.
