As we welcome July, Indiana seems to be in a very wet phase. Or, at least part of the state has been. The jet stream – a narrow band of fast-flowing air near the altitudes where commercial jets fly – naturally meanders in a north-south-north ribbon around the hemispheres. Typically, these “ribbons” also shift eastward…Read more about Storm Tracks Favor Some Parts of Indiana Skipping Others[Read More]
Vegetable Crops - General
A quick glance at my vegetable garden on Thursday, June 17, revealed a lonely Japanese beetle… I dutifully squished it! This does indicate that emergence is beginning in west central Indiana. Hatch has undoubtedly been going for several days in southern counties, whereas, northern counties will soon be graced with their presence. Oh joy! Japanese…Read more about Japanese Beetles Emerging[Read More]
Southwest Purdue Ag Center held a virtual field day on June 24, 2021. Multiple projects are highlighted at the virtual field day.

Topics related to vegetable production include: Pest and pollinator considerations in melon production Herbicide…Read more about Southwest Purdue Ag Center Virtual Field Day Research Highlight[Read More]
After the heavy rains in the past a few days, flooding/waterlogging injury stands out in my farm visit this week. Regardless of tomato or cucumber, the injured plants showed leaf yellowing that occurred 2 to 3 days after waterlogging (Figure 1). The yellowing leaves are a result of chlorophyll loss, which is associated with N…Read more about Plants Recovering from Waterlogging Damage[Read More]
As spring crops finish up, areas where no crop is planned for a month or more are good candidates for a summer cover crop. A number of species reliably establish well in the summer. The best one for a particular situation will depend on the length of time available, the desired benefits, and the following…Read more about Summer Cover Crops for Vegetables[Read More]
Many years ago, I was told that to successfully use fungicides on vegetables, one must use high spray pressures and hollow cone nozzles. However, I had trouble finding any research on this topic, just rumors. So, I did my own research. Dennis Nowaskie, Superintendent at the Southwest Purdue Agricultural Center (SWPAC) built a single row…Read more about Spray Pressure, Nozzle Type and Vegetable Disease[Read More]
Abnormally dry conditions are still lingering in parts of Indiana (Figure 1) with interest growing on how much the warmer weather might exacerbate the situation. Fortunately, the climate outlooks for the next several weeks and through June are favoring above-normal precipitation (in addition to above-normal temperatures), so hopefully any dry periods will be short lived….Read more about Growing Degree-day Accumulations Still Lag While Dry Conditions Linger[Read More]
Whether the focal crops are vegetables, field corn, or soybeans, we’re hearing from growers that poor germination has been an issue this season. The cool, wet conditions we’ve had this spring have delayed seedling germination and growth, and this just happens to be the perfect scenario for seed and root maggots to do their worst…Read more about Vegetable Seedlings with Emergence Issues? Seed Corn Maggot may be to Blame.[Read More]
In a recent Hoosier Ag Today/CCSI Soil Health Podcast, Stephen Meyers of Purdue Horticulture and Dan Perkins of Perkins Good Earth Farm covered spring management of cover crops on vegetable farms. They discussed a variety of methods for terminating: flail mowing and tarping, roller-crimping, tillage, and killing with herbicide. They pointed out that decisions about…Read more about Cover Crops in May: Soil Health Podcast on Spring Management and Observations of Winter Rye at Pinney Purdue[Read More]
It seems the weather pattern may have shifted toward wetter conditions. Over the past week, Indiana has received over an inch of rain and the 7-day forecast is predicting at least another inch (Figure 1) in the central and southern parts of the state. The northern counties of Indiana, that have been in the Abnormally…Read more about More Observers Needed to Monitor Precipitation Across Indiana[Read More]
