The Aug. topic of Strawberry Chat is about plasticulture strawberry production. Our special guests were Brad Bergefurd, former Horticulture Specialist at The Ohio State University, Calvin Beasley from Beasley Orchard in Danville, IN, and Danny Vanmeter from Vanmeter Family Farm in Clarkston, KY. We discussed many important topics in plasticulture strawberry production, including site selection,[Read More…]
A major difference between drip irrigation and other irrigation methods is that drip irrigation applies water to only a portion of the soil. This works great for vegetables grown on the plastic mulch, since no irrigation water is applied between the row middles; water applied to row middles encourages weed growth. So, does the soil[Read More…]
Root-knot nematodes (RKN) are a devasting soilborne pest on a wide range of vegetables and fruits. Root-knot nematode infections result in root swellings called galls (Figure 1). Heavily infected crops by RKN display aboveground symptoms such as stunted growth, wilting, and leaf yellowing. We often found root-knot nematode causes damage to watermelons, cantaloupes, and tomatoes[Read More…]

At Southwest Purdue Ag Center (SWPAC), more than 10 inches of rain fell since July 7; over 8 inches happened since the evening of July 24. Soil water content on the unirrigated tomato/pepper/eggplant bed (12’’ under plastic mulch) increased from 10% (early July) to about 15% after 3 inches of rain on July 7-9. The[Read More…]
We received more than 8 inches of rain since the evening of July 24 at Southwest Purdue Ag Center. This article discusses a few plant physiological disorders we observed after the heavy rains. We noticed a large percentage of cracked fruit on tomatoes at the stem end (Figure 1). Fruit cracking is a physiological disorder[Read More…]
We discussed insect pests and weed control during renovation in the July episode. Our special guests are Drs. Stephen Meyers, Samantha Willden, and Mr. David Doud. Steve and Sam are researchers from Purdue. Steve is the weed scientist in the Horticulture department; Sam is a postdoc researcher in the entomology department. David is the owner[Read More…]
We observed a large amount of unmarketable pepper fruit hanging on the plants during on-farm visits and at the research farms recently. Damage appears on the sides or at the bottom of the fruit (Figure 1). The symptoms that occur at the fruit bottom are similar to tomato blossom end rot (BER), a plant physiological[Read More…]
After planting on May 16, we only received 1.4 inches of rain in June. The early-setting tomatoes on plants grown on the unirrigated bed had more than 40% fruit blossom end rot (BER) (recorded on June 23). It was 3% on plants grown in a bed that received 17 irrigation events in June and 10%[Read More…]
