Excerpt from Fungicidal Control of South American Leaf Blight of Hevea RubbertreesIn a seedling nursery, the young, blight-susceptible leaves constantly unfolding become resistant to leaf blight when approximately 2 weeks Old. If infected before reaching this age, spore-producing lesions appear after about 1 week. By main taining a protective film of Spray on all young leaves, disease damage could be eliminated, but since leaf expansion is rapid and new leaves, are emerging on some plants in a nursery at all times, very frequent spray applications would be required for complete disease control by protective spray films.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
