Farmers and ranchers perform job responsibilities in all types of weather conditions including excessive heat and humidity. It is important for agricultural producers to understand risks associated with working in high heat work environments, potential heat-related illnesses, precautionary steps, and appropriate medical responses.
Spotted wing drosophila (SWD) is present on a number of farms in southeastern Pennsylvania and central Maryland. Larvae have been detected in cherries at the tail end of harvest and summer raspberries, blueberries, blackberries, and primocane-fruiting raspberries where lateral canes emerged from pruning stubs.
Utilizing all means of management for SWD -- including cultural and chemical options -- is recommended. The most suitable strategies for any farm will vary with the crop and circumstances.
This new pesticide label at http://www.cdms.net/ldat/ldALN000.pdf might be helpful, especially to organic growers.
Total fertility requirements in plasticulture are not different than those in conventional open-soil culture. With a drip irrigation system, however, application can be much more precise and timed with crop development.
Dr. Randy Gardner, Professor Emertus, North Carolina State University, has recently released three tomato hybrids with late blight resistance.
This is the first confirmed report of downy mildew on cucurbits in Pennsylvania.
This week late blight was confirmed in several additional counties in both commercial production fields as well as home gardens on both tomatoes and potatoes.
In this post, Dr. John Masiunas from the University of Illinois addresses the issue of what to do when vegetable or fruit crops are injured from pesticide drift.
Sweet corn growers usually deal with fall armyworms. This year we are also seeing problems of another species, true armyworm.
Late blight has now been confirmed in Blair, Franklin, Mifflin, Lancaster and Schuylkill Counties in Pennsylvania.
The cool, wet weather conditions we've been experiencing can result in herbicide injury to sweet corn. This post covers herbicide injury symptoms, how the weather can lead to herbicide injury and what to do if herbicide injury is a problem.
To-date late blight has been confirmed on five farms in four counties and more unconfirmed outbreaks are suspected.
This past week late blight was confirmed on potato and/or tomato in Blair, Franklin and now Mifflin Co., PA.
Today late blight was confirmed on tomato and/or potato in Franklin and Blair County, PA.
Many species that overwinter in Pennsylvania apparently have done so with high survival rates. For example, we’ve seen very strong populations of several species of maggots, cucumber beetles, and asparagus beetle in April and May. However, many of our pests tend not to overwinter, but arrive as long distant migrants. We can now confirm that the long-distant migrants listed below have also been reported in May.
The cucumber beetle has turned up this week in scouting of local greenhouse cucumber crops.
In 2007, fifty eggplant scions were grafted onto tomato rootstock that was resistant to Verticillium Wilt.
