We have just finished harvesting Pixie crunch from our plantings at the Purdue Meigs farm and the more I see this apple, the more I like it. Although we think of this as a relatively new apple, the original cross was made 45 years ago at Rutgers University and it was selected from a planting in West Lafayette, Indiana. Before being named Pixie Crunch, it was tested as Co-op 33. It resulted from a cross of two numbered apple selections but has both Golden Delicious and Rome in it’s pedigree. The Pixie Crunch tree is spreading and precocious. Our three year-old trees at the Meigs farm had about 80 apples per tree this year (Fig 1). Fruit size is just a little smaller than Gala and fruit finish is a dark red blush over a yellow background (Fig 2).  With open trees, most fruit will have over 75% color. What stands[Read More…]


Purdue Wine Grape Team Fall Workshop, October 6, 2016  9 am to 4 pm Dear Indiana Wine Friends, There is still time to register for our Fall Workshop on Thursday, October 6 at Purdue University.  This year’s Fall Workshop is designed for novice and seasoned wine growers and makers alike, and will provide an update on the most proficient production practices in the vineyard and winery. We will discuss topics ranging from sustainable post-harvest vineyard management to economical wine stabilization and aging practices. Participants will stop by the team’s pilot winery to discuss winemaking equipment, visit the enology lab to review must and wine analyses, and tour our research vineyard.   You should plan to arrive at the Purdue Meigs Farm at 9:00am EST for registration, coffee and donuts.  A shuttle bus will provide round-trip transportation from Meigs to the West Lafayette Purdue campus.  Lunch will be provided.  Dress casual and bring a bottle of[Read More…]

“During the past few years considerable complaint has been made in this state of the loss of apples through rotting.” George P. Clinton, 1902. It’s been quite a season for rot. High temperatures, coupled with regular rains created a perfect storm of summer rots. If you were one of the orchards with problems, you need to start thinking about what you are going to do differently next year. Black Rot: One square inch of cankered wood can produce over two million spores. 2,000,000! No protective or thorough spray can compensate for poor sanitation practices! These cankers appear on dying wood (2016 fire blight infections, opportunistic infection due to wind damage, or herbicide injury). Another great source of inoculum are windfalls, and mummies—even little mummies of thinned fruit! Black rot inoculum can be found on buds as early as October(!), just waiting for next spring. With the primary source of inoculum[Read More…]

Grape harvest continues across the state. Overall fruit quality has been excellent, but maintaining that quality with all the rain recently is challenging. Thin skinned varieties have fruit cracking and rot problems. Primocane fruiting blackberry harvest continues into its fourth week on Black magic, with APF-45 just getting started. Heritage and Caroline primocane fruiting raspberries are struggling through the heat and rain. Gray mold, spotted wing Drosophila and Japanese beetles are major concerns in brambles and growers should continue control measures. Apple harvest continues. Summer varieties are done and early fall varieties are being harvested.


I am still catching significant numbers of codling moths in my pheromone traps. That means that they are still mating and laying eggs on fruit. Even though you may be well into the harvest period, don’t forget that those later varieties still need to be protected from codling moth. Don’t forget to pay close attention to the pre-harvest intervals on whatever insecticide you choose to use.  


We just completed a new publication that will assist fruit and vegetable growers in protecting pollinators while still managing their insect pests. The title is “Protecting Pollinators in Fruit and Vegetable Production.” It can be found at https://extension.entm.purdue.edu/publications/POL-2/POL-2.html. There are two companion publications in this series, “Protecting Pollinators in Home Lawns and Landscapes” and “Protecting Pollinators: Tips for Commercial Agricultural Pesticide Applicators.” Additional publications in this series will target agronomic crop producers, folks who want to plant a pollinator garden, and how youth can help to protect pollinators.
