In the past week or so late blight has been confirmed in three additional counties in Pennsylvania.
Downy mildew is widespread on cucumbers across Pennsylvania.
Sweet Corn Growers… I have seen my corn ear worm trap numbers climb in the past 3 nights, averaging about 12 a night. That suggests a 4 day spray interval.
For organic late blight management there are two important things to re-member. The first is you cannot “cure” late blight. The other is scout frequently.
The growing season is not over yet and neither is late blight!
In-season cucurbit powdery mildew management is most effective when initiated early (one powdery mildew colony per 50 leaves).
In this past week, additional outbreaks of downy mildew on cucumber have been reported in Mifflin, Union and Lancaster Counties. It is also suspected in Snyder and Montgomery Counties.
With much of the region in drought, there is some concern about the success in trying to control certain weeds under these dry conditions.
Hot dry weather has been favorable for mite outbreaks. Generation turnover increases dramatically.

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.
