As the summer temperatures continue to climb, it is extremely important that employers and workers become familiar with the signs, symptoms, and dangers of heat illness. By taking the proper precautions, serious injury or death can be easily prevented.
Honey bees are important pollinators. They are also considered “managed” pollinators, because people manage honey bee colonies. However, unmanaged bees, comprised of various species that exist as wild populations, also play key roles in providing pollination of cucurbit crops. The degree to which different species of bees provide pollination services varies among cucurbit crops. It also changes as the season changes, and can even vary at different times of the day.
We are seeing a surprising and somewhat widespread increase in fall armyworm. We also are seeing the beginning of a 2nd generation of corn borer. Southwestern sites are continuing to have earworm counts above threshold. Check fields for signs of fall armyworm feeding.
Water can move a pathogen from one piece of produce to a large volume of product. Keep these tips in mind to keep your produce safe.
SWD numbers are up in most PA and MD locations, except for in fall raspberries which are still largely unripe.
A number of calls have come in this year regarding blueberry plants with few leaves – though some canes often appeared nearly normal – and berries on the same plant that ranged in size from normal to very tiny.
Interview with Beth Gugino, Vegetable Pathologist on managing Bacterial Canker in Tomato.
Late blight has now been confirmed in 10 counties on tomato and/or potato and is continuing to spread quickly.
Cucurbit downy mildew has not been confirmed yet in PA but was just confirmed on cucumber in Salem Co. in southern New Jersey yesterday.
Reduced air circulation and high relative humidity means an increased likelihood of seeing leaf mold in high tunnels.
Now this the time of year that we start seeing powdery mildew on cucurbits. Now is the time to be scouting your crops!
Mothersbaugh Farm is a 4 acre farm in Spring Mills, Pennsylvania established in 1977.
Governor Tom Corbett recently signed two pieces of legislation regarding the taxation of High Tunnels in Pennsylvania. While this simplified the property tax issue, there remains substantial confusion among growers as to what is required in order to legally construct high tunnels in their local municipality. In addition, what constitutes a high tunnel, greenhouse and sales facility as they relate to other agricultural production facilities varies from township to township and borough to borough.
Although cucurbit downy mildew has not been confirmed in PA, it is still important to be scouting your fields!
The weather has been ideal for late blight resulting in an increased number of confirmed reports across Pennsylvania.
Spotted wing drosophila was found in very low numbers in traps in southeastern PA (3 males out of 40 traps using a new commercially-available SWD Lure – Trece, Inc). Two of the SWD were in an unharvested cherry block, and one was in a trap in black raspberries. No female SWD were found at these sites yet, but judging from our brief experience with this pest in PA, it won't be long. Growers of raspberries (both red and black), blackberries, and blueberries in particular should be monitoring for SWD (check traps daily if possible), and should be prepared with effective materials for control.
People are concerned about the effect pesticides have on wildlife and the environment. Specifically, there is a lot of discussion about the role pesticides play in the decline of pollinators; both honeybees and wild insects.
USDA has recently noticed that some growers are using bleach (Clorox TM) as a disinfectant in post-harvest washing systems. Disinfectants are regulated the same way as pesticides and unless the label on the bottle indicates EPA approval for washing fruits and vegetables, it is against federal law to use it for that purpose.
Downy mildew confirmed on cucumber in Maryland but not yet in PA.
No new reports so far this week.
