Phytophthora infestans

Post by geordief » Fri May 28, 2010 9:31 am

Can anyone tell me the size of spore one is likely to encounter with potato blight?

The reason I ask is that I am trying to ascertain if any of the breathable membranes or sheeting (such as high-density polyethylene I think) might have holes small enough to allow them to be used as protective cover for potato plants.
I already know (I think) that horticultuaral fleece is not up to the task but wonder whether some of the commercial products such as the plastic pouches for breads and pastries (Cuisine de France) might actually be successful...

Phytophthora infestans causes severe crop losses worldwide, and the potato is probably the most important pathogen of potato and tomato today. This organization is one of those pariahs who once considered fungi, but not anymore.

The development of leaf rots or lesions varies with environmental conditions, like the temperature humidity, light intensity, and potato cultivation.
