When growers are asked about the top challenges in plasticulture strawberry production, frost/freeze damage are almost always at the top of the list. Anyone living in Indiana understands how unpredictable spring weather can be. This year, in southern Indiana, we experienced warm periods with average daily temperatures exceeding 60 °F in mid-February, followed by sharp…Read more about Spread out Flower Timing to Reduce Spring Frost/Freeze Risks in Plasticulture Strawberry Production[Read More]

A wet welcome to the growing season from Mother Nature. Weather this year in North Central Indiana has been characteristically dramatic. Recently, highs in the mid 80’s followed by lows in the mid 20’s not 48hrs apart. That with some warmer than average temperatures have landed us in a similarly jump-started spring as last year….Read more about Crop conditions[Read More]
Hi. As I’m sure most of you have noticed, the Japanese Beetles have arrived. We have been dealing with them in every fruit crop with the exception of our apples. The blackberries are currently being consumed by them despite a well-timed spray last week. Fire blight continues to show up in our orchard. We are…Read more about Crop conditions[Read More]
From 2022 to 2024, we evaluated the performance of 15 June-bearing strawberry cultivars grown in a plasticulture system using black and white-on-black plastic mulches at two locations in Indiana: the Southwest Purdue Agricultural Center in Vincennes, IN, and the Meigs Horticulture Research Farm in Lafayette, IN. During the experimental period, monthly average temperatures at the…Read more about Performance of 15 June-bearing Strawberry Cultivars Grown in Plasticulture System for Two Seasons in Indiana[Read More]
Hello! Fruit crop conditions are good here with the exception of our Rosalee apples. Unfortunately, they are heavily infected with fireblight. We are in the process of removing the affected trees and destroying them offsite. Some of our first raspberries are ripening up. Applications of fungicide, insecticide, and thinning chemical have been made on schedule.
This is the time of year where we receive numerous reports of off-target herbicide exposure. Grapevines and fruit trees sensitive to growth regulator herbicides, including phenoxy, benzoic, and pyridine classes of compounds. 2,4-D and dicamba are the most common products, and they are used widely in corn and soybean production. Damage can range from minimal…Read more about Tips for Avoiding Herbicide Injury[Read More]
The window for chemical thinning is rapidly closing in many parts of the state. Carbaryl can be effective up to 20 mm fruit diameter. After this stage, options become limited and we’re in a “rescue thinning” approach. Below is some information from Penn State University on rescue thinning options: Rescue Thinning Options – 20mm and…Read more about Chemical thinning[Read More]
From 2022-2024, we evaluated the performance 15 strawberry cultivars grown in plasticulture system using black and white-on-black plastic mulches (Figure 1) at two locations: Southwest Purdue Agricultural Center in Vincennes, IN (USDA hardiness zone 6b), and Meigs Purdue Agricultural Center in Lafayette, IN (USDA hardiness zone 6a). Strawberries were harvested for two seasons. Plug plants…Read more about Performance of Strawberries on Black vs. White Plastic Mulches in Indiana[Read More]
Hi! This week’s crop conditions are looking quite good despite not having any significant rain recently. Most crops have set fruit and are progressing well. The grapes received their second spray this season on the 9th. This is a busy time here at Meigs as we make raised beds for our vegetable crops and prepare…Read more about Crop conditions[Read More]
Spring is in full swing in our research high tunnels at Purdue. Overwintering strawberries that we planted in September are now in full bloom and fruits are being harvested. But as temperatures increase and crops become more productive, we also see the emergence of various insect pests. Aphids, amongst other soft-bodied insect pests (e.g., whiteflies,…Read more about Observations on the Companion Plant: Sweet Alyssum[Read More]
