Many cantaloupe and watermelon growers have planted transplants in the field or will soon. A question many growers often have is when and how should one apply fungicides. Applying fungicides according to a weather-based system is easy for cantaloupe and watermelon growers. MELCAST was developed at Purdue University by Rick Latin to allow growers to…Read more about MELCAST[Read More]

Getting seedlings from the transplant tray into the field is essential for a good crop (Figure 1). Healthy transplants treated well will quickly establish themselves in the field, setting the foundation for a productive crop. Here I offer some suggestions for successful transplant establishment. Harden transplants by exposing them to higher light, cooler temperature, and…Read more about Successful Transplant Establishment[Read More]
The cool, wet weather we have been having is perfect for the root and seed maggots in early planted vegetables. I have already received calls about onion maggots. If you are planting early vegetables, check out the article in the March 17, 2015, issue of the Hotline for 2015. So, how do we define early…Read more about Root and Seed Maggots[Read More]
For most insect pests, we have some viable options to manage them organically. For years we have been looking for an organic solution for striped cucumber beetle and bacterial wilt on melons and cucumbers. It appears that we now have a viable option. There is a relatively new product, Cidetrak D, manufactured by Trece, which…Read more about Organic Control of Striped Cucumber Beetles[Read More]
As you all know, many of our vegetable crops are dependent upon pollinators to move pollen from flower to flower. The cucurbits, muskmelons, cucumbers, watermelons, pumpkins, and squash, are completely dependent on insect pollination. Eggplant, okra, lima beans, and peppers will set fruit without pollinators but can have increased yield if pollinators are present. Honey…Read more about Honey Bees and Other Pollinators[Read More]
In December 2014, I described the ‘Yearbook of Agriculture, 1928”. In that blog, I wrote about processing tomato production in 1925 and 2013 (the ‘Yearbook of Agriculture, 1928’ lists data back to 1925). Today, I would like to discuss cantaloupe and watermelon production. Unfortunately, yields posted in the “Yearbook” are in different units than in…Read more about Cucurbit Production in Indiana: 1925 and 2013[Read More]
Read more about Cucurbit Production in Indiana: 1925 and 2013Three species of seed and root maggots attack vegetables in Indiana. The seedcorn maggot feeds on seeds and seedlings of sweet corn, cucurbits, lima and snap beans, peas, and other crops. Cabbage maggots can cause serious damage to transplants of cabbage, broccoli, cauliflower, and Brussels sprouts and make the fleshy roots of radishes, turnips, and…Read more about Seed and Root Maggots[Read More]
Bacterial fruit blotch is a disease that can affect most cucurbits (see Figure 1). However, the symptoms are most often observed on watermelon. A brief description of this disease and some photos can be found here. This article will introduce new recommendations for this disease in Indiana. Details of these recommendations can be found in the Midwest Vegetable Production…Read more about Bacterial Fruit Blotch Update[Read More]
The title of this article is pretty scary. But it isn’t entirely accurate. Pumpkins won’t really rot from the inside out. In this article, I will describe one way in which pumpkins can seem to rot from the inside out. Recently, I was asked to visit a field of pumpkins where the pumpkins were soft…Read more about Pumpkins Rotting from the Inside Out[Read More]
Over the past few weeks, I have observed several watermelon fields with relatively large areas of wilted plants.There can be several reasons for such symptoms.In the article below, I will discuss late season Fusarium wilt of watermelon.In a separate article, I will discuss mature watermelon vine decline.In a separate article/blog I discussed root knot nematode.All…Read more about Late Season Fusarium Wilt of Watermelon[Read More]
