Book Description
Alfalfa, Medicago sativa L., is one of the best quality dairy forages and as the principal forage legume in the U.S., is grown on roughly 10 million ha. Potato leafhopper, Empoasca fabae Harris, is its most economically damaging insect in the Midwest and northeast United States. Integrated pest management (IPM) programs for E. fabae in alfalfa consist of sampling and monitoring throughout the season, foliar insecticide treatments when economic thresholds are reached, host plant resistance and the cultural control of early harvest when economic thresholds are reached within a week of a planned harvest. The work presented here gives a thorough review of E. fabae ecology and biology, migration patterns and injury to host plants. A thorough review of available pest management strategies for E. fabae in alfalfa is discussed (chapter 1). An IPM system incorporating host plant resistance and orchardgrass intercroppings as a cultural control is studied with regards to affects on E. fabae abundance and alfalfa yield and forage quality (chapter 2). Alfalfa yield loss response to E. fabae feeding is assessed in order to validate the current economic injury level and economic threshold models for both susceptible and resistant alfalfa varieties (chapter 3). Lastly, soil fertility treatments are considered as a potential cultural control tactic for managing E. fabae in response to farmer observations (chapter 4).

Book Description
Forages: The Science of Grassland Agriculture, 7th Edition, Volume II will extensively evaluate the current knowledge and information on forage agriculture. Chapters written by leading researchers and authorities in grassland agriculture are aggregated under section themes, each one representing a major topic within grassland science and agriculture. This 7th edition will include two new additional chapters covering all aspects of forage physiology in three separate chapters, instead of one in previous editions. Chapters will be updated throughout to include new information that has developed since the last edition. This new edition of the classic reference serves as a comprehensive supplement to An Introduction to Grassland Agriculture, Volume I.
