Book Description
Compendium of Cotton Diseases, Second Edition provides practical, up-to-date information on the diagnosis and control of cotton diseases worldwide. This new edition begins with an overview of the origin and evolution of cultivated cotton and a description of the growth and development of the plant, which is fundamental in disease diagnosis and effective management strategies. Expanded disease sections include detailed pathogen descriptions, characteristic symptoms that occur, the disease cycle, and control information. Includes twice as many color photographs as the first edition.Additional improvements include:-greater attention to noninfectious disorders, including nutritional disorders, herbicide injury and toxicity, and environmental stresses.-sections on common disease interactions, host plant resistance to pathogens, and general principles of disease management in integrated production systems.

Book Description
The root-knot nematode, Meloidogyne incognita, and the seedling pathogen, Thielaviopsis basicola, commonly co-exist in Arkansas cotton fields and may interact resulting in increased losses. The primary objective of this research was to evaluate the effects of soil physical parameters on these soilborne pathogens and cotton growth in controlled environmental, field, and microplot studies. Controlled environmental experiments used two soil bulk densities and four pathogen treatments: non-infested soil, soil infested with M. incognita or T. basicola and soil infested with both pathogens. The results indicated bulk density generally did not affect seedling growth or disease since soils had low penetration resistance under well-watered conditions. The combination of M. incognita with T. basicola reduced seedling stands and root volume more than either pathogen alone. Both M. incognita and T. basicola reduced root topological characters, but only M. incognita changed the root topological index. The effects of subsoiling and application of the nematicide 1,3-dichloropropene (Telone II®) on root system development and plant growth were investigated from 2009 to 2011 in a cotton field in northeastern Arkansas. Subsoiling did not consistently affect early season growth. Nematicide treatment consistently improved seedling growth for one or more parameters in 2010 and 2011. Root galling and the population of M. incognita were suppressed by Telone II®. Neither subsoiling nor nematicide application affected cotton development or root topology. The effects of a soil hard pan (HP) and M. incognita on cotton root architecture and plant growth were evaluated in a microplot study in 2010 and 2011 at Hope, Arkansas. An artificial HP was created 20 cm below the soil surface in half of the microplots. Pathogen treatments included soil infested with T. basicola plus four different M. incognita levels (0, 4, 8, 12 eggs/cm3 soil). Generally, soil HP improved seedling growth due to higher soil water contents above the HP layer. M. incognita reduced taproot length, delayed cotton maturity and reduced seed cotton yield. Root topology provides a new approach to quantify the changes caused by soilborne pathogens and soil physical factors and will help in crop management in the future.
