Nepali plants to fight potato blight
Researchers in Nepal have identified five plant extracts that are effective against late blight ( Phytophthora infestans) in potatoes. The tested plants were black mustard ( Brassica nigra), camphor ( Cinnamomum camphora), chinaberry trees ( Melia azedarach), Lantana camara and Eupatorium adenophorum. Of the five, black mustard and L camara were the most effective, having around four times the activity of the least effective species, C camphora, and twice that of the other two species tested. However, the amount of raw material needed to produce an effective fungicidal extract also varied greatly among plant species. Details of the study were published in the Nepal Journal of Science and Technology.
