Excerpt from The Control of Tomato Leaf-SpotThe use of Bordeaux or other copper-spray mixtures has given the most effective control of leaf-spot in the past, but the profits from spraying are variable and not always sufficient to justify the ex pense. A more effective and economical method of control lies in the use of modified field practices.The effects of tomato leaf-spot epidemics can be largely avoided by setting out large, stocky, well-hardened plants early in the spring. As the leaf-spot fungus has a high minimum sporulation tempera ture, viz, 59° F., and therefore seldom infects tomato plants in the field in the Middle Atlantic and Middle Western States, the region where it is severe, before June 15 to 30, these early plants escape more leaf-spot than the small plants commonly set late.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
