Lesions are usually water-soaked (Figure 1). In severe cases, the fruit may be affected. The lesions on fruit are often raised (Figure…Read more about Bacterial Spot of Pepper[Read More]

I often receive questions on how much water should apply to high tunnel tomatoes. Even the most experienced tomato growers could sometimes lose yield because of overlooking irrigation management. In this article, I describe a case study of how we use soil moisture sensors for irrigation management in a high tunnel tomato production system. This…Read more about A Case Study: Irrigation Management in High Tunnel Tomato Production[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 about Rely® 280 Added to Row Middle Weed Control Arsenal in Select Crops[Read More]
Tomatoes need a consistent water supply when they start to bloom and set fruit. As plants grow more foliage and have more fruits set, their water needs increase. As a result, the irrigation amount must steadily increase to maintain the consistent soil water content and the water supply to the plants. What would happen if…Read more about Tomatoes Need a Consistent Water Supply[Read More]
Tomato pith necrosis is a bacterial disease of tomatoes that occurs sporadically, usually in greenhouses or high tunnels. While this disease can kill or at least ruin marketable yield on tomatoes, the disease usually affects perhaps only a handful of plants in a greenhouse. That is, the disease does not seem to spread beyond the…Read more about Tomato pith necrosis[Read More]
At the Purdue Student Farm, we are in full swing with our Colorado Potato Beetle (CPB; Figure 1) management program. On this small farm, these beetles are a consistent threat to the potato crop. This is in part due to their limited ability to rotate, as the whole farm is smaller than the recommended rotation…Read more about Are You Scouting Your Potatoes? The Beetles Are Here![Read More]

The importance of bees for providing pollination is a regularly discussed topic in many fruit and vegetable production systems. Although tomatoes are often pollinated by wind, they too can benefit from bee pollination. Recent research suggests that tomato flowers visited by bees have a larger fruit set and produce heavier fruits. An ongoing study in…Read more about Pollination Services in Tomatoes[Read More]
