This week, several regions of Indiana experienced excessive rainfall due to the remnants of Hurricane Beryl passing through the state. The heavy rain caused flooding in some vegetable fields. When soil water levels surpass optimal requirements, oxygen is depleted, leading to waterlogging stress for the plants. Figure 1 displays the varied responses of different crops[Read More…]

By now, most watermelons have been planted in southern Indiana, and most fields are currently in the vegetative growth stage. The earliest planted fields have begun to set fruit. In the past two weeks, I have observed herbicide damage in a few watermelon fields. Although the application rate and method were consistent with the labels[Read More…]
The seedcorn maggot, Delia platura, is one of the first pests that will cause damage to vegetables in the spring in our region. This fly, which resembles a house fly but is smaller (Figure 1), begins to emerge from the overwintering pupal stage in the soil in early spring. Upon emergence, the flies quickly aggregate[Read More…]
Are you still thinking about varieties for the upcoming season? Purdue has been keeping a record of vegetable variety trials in the Midwest since 1999. The Midwest Vegetable Trial Report series includes reports of applied research relevant to vegetable and melon production in the Midwest. Here are some abstracts of the most recent reports. Visit the Midwest Vegetable[Read More…]
Earlier this year, Rely® 280 was registered for use in transplanted cantaloupe, cucumber, pepper, summer squash, tomato, and watermelon with a supplemental label. The registration allows for the use of Rely® 280 for pre-plant burndown and post-directed applications to row middles. Previously, postemergence burndown and row middle options were limited to glyphosate (Roundup®), carfentrazone (Aim®),[Read More…]
Most of us know a temperature lower than 32°F would kill tender vegetables like tomatoes, peppers, melons, and cucumbers. Home gardeners would wait to plant those crops after the last frost passed, but commercial farmers may take the risk of planting earlier to capture early-season premium prices. Farmers use various strategies, i.e., high tunnels, low[Read More…]
We are excited to announce that the Southwest Purdue Agricultural Center Field Day is scheduled for June 28, 2023, at the Southwest Purdue Agricultural Center (SWPAC), 4669 N. Purdue Rd. Vincennes, IN. Purdue researchers and NRCS representatives will present their current research and demonstration projects in fruit and vegetable production conducted at SWPAC. The topics[Read More…]
At Southwest Purdue Ag Center (SWPAC) and Pinney Purdue Ag Center (PPAC), we demonstrate irrigation impacts on several fruiting vegetable crops. Tomato, pepper, eggplant, watermelon, and cantaloupe are planted on plastic-covered beds with drip tapes. They grow on beds side-by-side with and without irrigation. We used two approaches to schedule irrigation, one bed is irrigated based on[Read More…]
This time of year, when we are busy in the fields planting and prepping for a fruitful season, we need to be observant of the pest pressures that may be present. We have already had reports this year of cucumber beetles feeding on recently transplanted cucurbit crops, in particular melons and cucumbers. Let’s review why[Read More…]
MELCAST is a weather-based disease-forecasting program that helps growers schedule foliar fungicide applications for watermelon and cantaloupe. MELCAST stands for MELon disease for CASTer. This program, designed by Dr. Rick Latin, Emeritus Professor of Plant Pathology at Purdue University, keeps track of weather conditions so that cantaloupe and watermelon growers can apply foliar fungicides to their crops when they[Read More…]
