Control Options

Strawberries are available in grocery stores 365 days a year. This is largely due to the fact that berries are shipped from different locations across the United States and around the world. However, in the eastern United States, fresh, locally-grown strawberries are only available at farmers markets, roadside stands, and grocery stores for several weeks during the late spring and early summer. This limited availability occurs mostly because the commercial strawberry production in the East is derived from June-bearing varieties, which have a brief production season.

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.

The black vine weevil is a widespread, entrenched pest in many nurseries in Maryland. Once it is introduced into a production nursery, BVW is extremely difficult to eliminate. While foliar damage caused by adult weevils is a cosmetic concern, larvae of the black vine weevil cause serious root injury and girdling of azaleas, rhododendrons, yews, and many conifers.
