2009-2010 Pest Management Recommendations for Field Crops

This bulletin is divided into three sections - disease and nematode control, insect control, and weed control. The recommendations are listed according to crop and then pest. In the table of recommendations given under each crop, the pesticide recommendations are given in units (pints, pounds, and so forth) of commercial products. In most cases, the amount of active ingredient to be applied is given. This information will be useful if the pesticide is commercially available at different concentrations. If a pesticide concentration differs from that recommended, determine the amount of a given formulation you need to use to apply the pesticide at the recommended rate. For example, if the recommended rate is 1 pound of active ingredient, then you should use 2 pounds of a 50 percent, wettable-powder formulation. If the formulation is a liquid, you must know the pounds of active ingredient per gallon to make this calculation.

Japanese Maple Scale Woody Ornamental Host Plants (EB-1)

Japanese maple scale (JMS), (Lopholeucaspis japonica Cockerell) (Hemiptera: Diaspididae), is a prolific pest of major concern to nursery crop producers and landscape managers in MD and the eastern United States. JMS is difficult to monitor and manage due to its small size, extended crawler emergence periods, and wide host plant range. The purpose of this fact sheet is to provide practitioners with host plant information that will help to improve and focus their monitoring efforts. All plants listed in this fact sheet are verified as hosts of Japanese maple scale from published literature or direct observations by the authors. This list should not be considered all inclusive. Due to the generalist feeding habits of JMS there are likely more hosts we have yet to identify including additional cultivars/hybrids. Authors: Paula M. Shrewsbury, Nancy M. Harding, Marie S. Rojas, and Stanton Gill; Title: Japanese Maple Scale Woody Ornamental Host Plants (EB-1)

Japanese Maple Scale: A Pest of Nursery and Landscape Trees and Shrubs (FS-967)

Unless Japanese Maple Scale (JMS) is monitored carefully and controlled early, populations of this armored scale can spread throughout a nursery or landscape to many species of woody plants and build up to levels that cause dieback and even death of infested plants.
