Damage by broad mites can be quite severe on tomatoes and peppers so growers need to be prepared to protect crops with an effective miticide before these pests cause economic loss.
Since 1980 when I was a young Extension Vegetable Specialist at North Carolina State University, fresh out of the old Vegetable Crops Department at Cornell University, I have been involved in conducting applied research and extension programming on the utilization of plastics in agricultural applications.
To help growers manage basil downy mildew in Pennsylvania, the Pennsylvania Department of Agriculture approved 24(c) labels for both Subdue Maxx and Hertiage for use on transplants grown for re-sale to consumers.
The recent prolonged wet weather has created conditions favorable for the bacterial disease blackleg on potato.
Prolonged periods of leaf wetness and high relative humidity create conditions that are perfect for pathogen spread and disease development!
Although it is a littler earlier than usual to be thinking about cucurbit downy mildew in Pennsylvania, it has been confirmed on several cucurbit hosts including cucumber, cantaloupe, yellow squash, butternut squash and watermelon in several counties in South Carolina and most recently on cucumber in North Carolina.

Researchers believe that long term honey bee declines are a result of a complex set of factors. The primary suspects are: poor nutrition, pesticides, pathogens/ parasites, and poor quality genetic stock. Here we will consider recent research results describing how pesticides might affect pollinators.
Flea beetles have emerged from their overwintering homes in the shrubby or wooded areas surrounding fields and begun to feed on the first spring brassica plantings. This article from UMass Extension's Vegetable Notes (Vol.27 Number 6) has great information on flea beetle management.
When growers send in strawberry leaves for a nutrient analysis, should the petioles remain attached or be removed?
Leaf miners seem to be especially noticeable this spring in both conventional and organic fields. If you are seeing white meandering tunnels in your beet, spinach and chard leaves you are not familiar with, read on for management tips.
Celery leaf curl is a relatively new disease of celery in Pennsylvania and the U.S. In an effort to learn more about the disease, we are interested in collecting as many samples as possible in 2015.
One consistent theme over the past several years has been the specter of dealing with bacterial diseases in our tomato fields and high tunnels. Bacterial speck, spot and canker have become regular challenges for Pennsylvania and Mid-Atlantic tomato growers. In spite of these challenges, it is possible to grow profitable tomato crops in this region.
These maggots attack seeds and small seedlings. While cabbage maggot and onion maggot attack only the seeds and seedlings of their namesakes, seed corn maggot will attack many plant species. Peak flight for the first generation of seed corn maggot was May 2nd in SE PA. Maggots have been confirmed in three fields in Adams, Lehigh and Lancaster Counties. Cabbage maggot is at 25% emergence and onion maggot is not out yet.
Penn State Extension’s Black Cutworm Monitoring Network has now detected six significant flights of this migratory pest species across the state. Black cutworms are a bit more active than usual this year; thus, growers generally need to be aware of this situation and watch your fields as the spring progresses.
Project addresses barriers to using biodegradable plastic mulches.
Dr. Cassandra Swett started at University of Maryland, College Park as the new grape and small fruit pathologist in May 2014, with a split research and extension appointment. Her primary functions are to develop basic and applied information that improves management of grape and small fruit diseases, provide a resource to extension specialists and educators, and communicate information on disease management to producers.
Real time disease updates are now available for berry growers. "Follow" on line or via your smart phone!
The strawberry bloom has begun and it’s time for fruit rot protection. Our two main targets for bloom time protection of strawberries are gray mold/ Botrytis fruit rot (Botrytis cinerea), and, if you are growing susceptible varieties like Chandler, anthracnose fruit rot (Colletotrichum acutatum).
Domestic honey bees hives are down by 59% compared to 60 years ago with rapid declines over the last forty years. This long term decline was punctuated by recent average losses of 30% per winter since 2006. The populations of some native bee species may also be declining.
