Plants that Attract Pollinators and Natural Enemies 2015 In this presentation plants that gardeners and growers could use to attract both pollinators and natural enemies to their vegetable crops are discussed.
Disease Management - Botrytis Botrytis is the major disease on a grower's radar screen Infections can occur early in the season during bloom and later in the season from bunch closing on to harvest.
Early Season Insect Management: Flea Beetles Identification and Biology Grape Flea beetles, Altica spp. (Coleoptera: Chrysomelidae), are small (4-5 mm), oval shaped, metallic blue-purple beetles that jump when disturbed. Grape flea beetles overwinter as adults and become active on warm April days when grape buds begin to swell. Adult beetles are most numerous following mild winters.
Early Season Insect Management: Climbing Cutworms This general term applies to the larvae (caterpillars) of a large number of butterfly/moth species (Lepidoptera) in the noctuid family that feed on buds, young shoots and leaves. Cutworm damage most commonly occurs in vineyards with weeds under the trellis or mulch, and in sandy or light colored soils.
Early-Season Disease Management Growers should apply a series of protectant fungicide sprays to new shoots to protect them from several diseases, beginning shortly after bud break.

Grape Berry Moth Although the Japanese beetle is rapidly moving to the top of the list in many areas of Maryland the grape berry moth (Paralobesia viteana; GBM) has typically been the most significant insect pest in the vineyard due to its direct and indirect damage to the berries and clusters.
Japanese Beetles Japanese beetles can periodically be a significant pest in Maryland vineyards. They create large holes in the younger leaves of vines and cause severe lacing and even fruit damage in heavy infestations. The population build up is typically periodic and cyclic and may require control tactics in years of large infestations.
Tomato Plastic Mulch and Shade Study Tomato plants were transplanted on 7 May 2012 into black (grower standard), white or reflective plastic mulch. Five different varieties of tomato were used: Mt Spring+, Celebrity, Mt Fresh+, Crista and Scarlet Red. When tomato plants began to develop fruit, a 30% shade cloth was randomly placed over 6-10 plants per row.
Virus Transmission by Striped Cucumber Beetle in Pumpkins Growers in the mid-Atlantic have been complaining about early season (late June early July) virus infections of their cucurbit crops, most notably pumpkins, squash and cucumbers and much less in watermelon and cantaloupe.
High Beef Prices Ag Marketing - News Update Retail beef prices are at a 20 year high.  I have been asked why?  Why is beef so high? The reasons:
Organic Weed Control in No-Till Vegetable Systems Organic vegetable growers have a hard time managing weeds, as there are no reliable Organic Materials Review Institute (OMRI) chemicals for controlling grass or broad leaf weeds. Most of the time growers depend on tillage for weed control, but excess tillage can lead to destruction of soil structure and the loss of carbon from the soil.
