|Droplet Chart / Selection Guide||
When choosing nozzles/droplet sizes for spray applications, applicators must consider both coverage needed and drift potential. As a rule, smaller droplets provide better coverage, but larger droplets are less likely to drift.

|Nozzles: Selection and Sizing||
This fact sheet covers nozzle description, recommended use for common nozzle types, and orifice sizing for agricultural and turf sprayers. Proper selection of a nozzle type and size is essential for correct and accurate pesticide application. The nozzle is a major factor in determining the amount of spray applied to an area, uniformity of application, coverage obtained on the target surface, and amount of potential drift.

|Pest Management Guide: Home Grounds and Animals, 2017||
This 2017 Virginia Pest Management Guide provides the latest recommendations for controlling diseases, insects, and weeds for home grounds and animals. The chemical controls in this guide are based on the latest pesticide label information at the time of writing. Because pesticide labels change, read the label directions carefully before buying and using any pesticide. Regardless of the information provided here, always follow the latest product label instructions when using any pesticide.

|2017 Spray Bulletin for Commercial Tree Fruit Growers||
Integrated pest management (IPM) is the approach emphasized in this guide; some aspects of IPM are incorporated throughout, although this guide mainly deals with the chemical component of IPM. IPM combines biological control from predators with selective chemical application for maintaining pest populations below economic threshold levels. This approach requires that growers give careful consideration to the selection, application rate and timing of chemical sprays. The degree of integration achieved will vary according to the management ability, training and objectives of the orchardist. Inadequate monitoring or implementation of IPM practices will lead to unsatisfactory results. In order to encourage the biological control components of the program, growers must consider the toxicity of chemicals to predators (Table 9, page 59) in addition to their efficacy against fruit pests (Tables 7 and 8, pages 56-58).

|Importance of Farm Phosphorus Mass Balance and Management Options||
Phosphorus is a naturally occurring element that is one of 16 elements essential for plant growth and animal health. Research has documented that applying phosphorus in fertilizers or manure increases crop growth and yield on soils that are below critical agronomic levels, as measured during routine soil testing. Although the economic benefits of phosphorus fertilization on crop production are well-documented, too much of a good thing can be detrimental to the environment. Excessive soil phosphorus is a potential threat to water quality.

|Control of Brown Marmorated Stink Bug with Insecticide-Treated Window Screens||
In Virginia and other Mid-Atlantic states, the invasive brown marmorated stink bug (BMSB) has become a serious nuisance pest (Rice et al. 2014). Each fall, these insects aggregate on buildings seeking shelters in which to spend the winter months.

|Plant Injury From Herbicide Residue||
In recent years, an increased number of cases of injury from herbicide residue in straw/hay, manure, and compost have been diagnosed in the Virginia Tech Plant Disease Clinic. Growers are surprised and dismayed to learn that manure, straw, mulch, or other amendments intended to improve their garden or landscape might have such unforeseen consequences. Of particular concern to organic growers are herbicide residues.
