This article was written on April 17. Harvesting of high tunnel-grown strawberries has started from southern to central Indiana. Early cultivars in open-field plasticulture are fruiting in southern Indiana, with harvest right around the corner. The crops are generally a week earlier than last year. Late cultivars, second-year patches, and fields covered with straw in[Read More…]

All that new, succulent growth needs to be protected to prevent primary (and even secondary!) scab (Fig. 1). We’re past the point where copper can be safely used, so protectant fungicides for scab control at this stage include mancozeb, ziram and captan. As an added bonus, all of these protect against the summer rots, and[Read More…]
The Two-spotted lady beetle, Adalia bipunctata, is a common insect predator, meaning it feeds on other, smaller bugs. Native to North America and Europe, the Two-spotted lady beetle is distinguished from other lady beetles by its oblong shape and two large black spots on either of its back, as well as its large white spots[Read More…]
Overwintering strawberries in high tunnels can jumpstart plant growth in the spring and protect developing flowers from frost damage and disease. However, this protected environment is also ideal for some pests, like spider mites and aphids, that can successfully overwinter and build their populations. We conducted an experiment on ‘Chandler’ strawberry where it was grown[Read More…]
As of right now, we simply do not know if we will have crops from our woody fruit producing plants, from apples to grapes to peaches. Remember: The ability to produce fruit is determined in the spring with flower development. Any factor, whether abiotic, insect or pathogen, that interferes with flower development will impact fruit[Read More…]
Attention strawberry growers, A group of scientists are conducting a survey about growers’ current practices and opinions about agricultural mulches in their strawberry fields. They hope growers could share with the research team information about current practices and opinions about different types of agricultural mulches by completing a short online survey. The survey is located[Read More…]
The Purdue Meigs Horticulture Facility in Lafayette, Indiana just south of campus is looking lively this time of the year. All our fruit crops and trees have begun development. I know last year I said we had a warm winter and early spring but this year was much warmer and earlier. I was working fields[Read More…]
In Indiana, our ‘normal’ or average weather is one of extremes, punctuated with an occasional glorious summer day of sun and 76 degrees F. This year has been one of flooding and droughts, freezes and scorching heat. Again. With these weather extremes come physiological disorders and summer fruit rots, for those lucky enough to even[Read More…]
