Figure 1. Blossom end rot of tomato.

We recently received several calls reporting blossom end rot of tomatoes (Figure 1). Although blossom end rot is caused by deficient supply of calcium to the developing fruit. The occurrence of this physiological disorder often relates to inconsistent supply of water. As a general rule, vegetables require 1-1.5 acre-inches of water per week. Since there is no rain in high tunnels, all the required water should be applied through irrigation. How does one determine if enough water has been applied to vegetables? This article provides some ideas. The first information needed is the irrigated area. For example, tomatoes are growing in a 30 × 96 high tunnel with 6 beds that are about 4 feet wide. Then the irrigated area is about 2,304 square feet (6 × 4 × 96 = 2,304). An acre has 43,560 square feet. So the irrigated area is roughly 2,304 / 43,560 = 0.05 acre.[Read More…]

Three videos on in-row weeding tools (Finger weeder, Torsion weeder, Tine harrow) were developed at the Michigan State University Department of Horticulture. Each video is 20 minutes: introduces the tool, how it works, different models, show adjusting the tool in the field, and a short interview with a farmer who uses the tool. These videos can be accessed at the MSU Mechanical Weed Control Channel https://www.youtube.com/channel/UCH-k889oYbUaEznvgiDtrOQ


Produce display with FoodLink

Would you buy something if you didn’t understand how it worked or what to do with it? Likely not… Imagine a customer of yours who doesn’t know how to select, prepare or store the fresh healthful produce that you are growing and offering for sale. How likely is it that they will buy that product? Or buy it twice? What are we doing at the point of sale to encourage that purchase? Your produce may be cosmetically perfect and 100% healthful but is it able to communicate to the customer anything about its selection, use or how much their family will enjoy it if prepared properly? Most every packaged, ready to eat, value added product in the grocery store is designed to convey these messages in a loud and clear format…Have you seen the breakfast cereal aisle in the grocery store lately? Those products are conveying an undeniable “BUY ME” message and they are directly competing for customer dollars with your silent but beautiful (and healthful) produce every day. There[Read More…]

Thinking of sending samples of your vegetables to the Plant and Pest Diagnostic Lab for diagnosis or insect ID? Here are some tips to help the samples arrive in the best possible condition for testing. Fill out a sample submission form. Download at: https://ag.purdue.edu/btny/ppdl/Pages/physicalspecimens.aspx If sending more than one kind of plant or problem be sure to label each bag specifically and fill out a separate form. The PPDL is closed on weekend so if you are sending samples make sure you send them early in the week so they are not in transit over a weekend. Express delivery (next day or second day) is preferred for samples that may not hold up well. You are also welcome to deliver samples to us on campus. See our website for location, parking and other information. Information we need to make the most of your sample: Symptoms you are seeing (your main[Read More…]


One can hardly glance at the news recently without noticing an item about the health of bees and other pollinators. We can all agree on the importance pollinators play in the health of our planet and the critical role honey bees and bumble bees play in agriculture. There is no doubt that populations of honey bees in particular have been in decline over the last several years. The multiple reasons for the decline are not as clear. This article will address the role that fungicides may play in bee health. There are many possible reasons for the decline of bee populations. Pesticides have been implicated in bee declines. Most experts would agree pesticides may play a role in bee population declines. The type of pesticide that is most often implicated in bee declines are the insecticides. This makes sense: bees are insects. There is less known about the role that[Read More…]


Many pesticides for use on vegetables have varying rules for use in different states. This article will review the different classes of labels for pesticides and where to find labels online. The shorthand names for classes of labels come from the section of the Federal Insecticide, Fungicide, and Rodenticide Act that governs each class. National labels are called Section 3 labels. These labels are approved by EPA for uses throughout the country. The Master Label on file with the EPA includes all registered uses. The label on a marketed product often contains only a subset of those uses. Even with federal approval of a Section 3 label, in order to be sold and used in Indiana, the product must also be registered with the Office of the Indiana State Chemist. To find products that are registered in Indiana, visit the NPIRS public web site. http://npirspublic.ceris.purdue.edu/state/state_menu.aspx?state=IN. Search by product name, EPA[Read More…]
