Usually I wait until January before releasing information about the Midwest Vegetable Production Guide for Commercial Growers (ID-56).   For two reasons, however, I would like to talk about the 2017 ID-56 now. This year, we welcome Michigan growers and Michigan State University to the Midwest Vegetable Production Guide The Guide is now an 8-state publication. We expect the ID-56 to be available in mid-December this year, instead of the beginning of January. Read below to find many new changes to the 2017 ID-56. New and Revised Sections We added a chapter for Celery with the help of MSU. We added a section called Selected University Diagnostic Laboratory Services, which includes contact information for each state. We revised the organic section to list certifiers on a regional basis. The Soils and Fertility section has been modified and updated. Disease Management We updated the Disease Management section. We updated the Orondis® products[Read More…]

Aphids can be one of the most damaging and hard to control pests during the winter months in high tunnels. The first step to managing aphids is to develop a scouting plan. Aphids reproduce clonally and develop quickly leading to very large population build-up in a short period of time. Therefore scouting is recommended at least three times a week. When examining plants be sure to look at the growing point and underside of leaves, where aphids prefer to colonize (Figure 1). Outbreaks commonly begin on the outer rows or the start of the row so these are places to be sure to include when scouting. In the summer months, successful control has been achieved using a soap/mineral oil spray consisting of 1.5% castile soap and 0.25% mineral oil. Cornell University also reports grower success using the biopesticides Mycotrol O and BotaniGard. These are commercially available formulations of the aphid-attacking[Read More…]

Tomato Grafting Workshop  Date: November 14, 16,17, 2016 2:00 PM to 3:00 PM (EST) Location: Southwest Purdue Ag Center (SWPAC), 4369 N. Purdue Road, Vincennes, IN Grafting has the potential to control soilborne diseases and increase yield of high tunnel grown tomatoes. Grafted tomato transplants cost about $2-$4 per plant. High cost prevents growers using this technology. By developing a simple system, grafting tomatoes can be conducted at your own farms. To help tomato growers learn grafting technology, we plan to organize tomato grafting workshops at SWPAC this fall. The workshops will be conducted on Nov. 14, 16, 17, from 2:00 pm to 3:00 pm (EST). The workshop is free, but please call us to register and pick the day that works best for you. To ensure every participant receives adequate hands-on practice opportunity, no more than 10 participants will be accepted on each day.  To register, please call (812) 886-0198.[Read More…]


This is the final issue of the Vegetable Crops Hotline (VCH) for 2016. Now is the time for subscribers who receive a paper copy in the mail to renew. A renewal form is included with this issue.

IVGA members will have their VCH subscription renewed when they renew IVGA memberships and do not have to send in a separate renewal form for the newsletter. An IVGA membership form is included here too. Thank you very much for your support of VCH. If you have any suggestions, ideas, comments, please do not hesitate to send[Read More…]


In issue 619 and 620 of the Vegetable Crops Hotline newsletter I gave you a brief background of the materials used and methods followed during the variety evaluation. I also discussed some of the challenges we encountered while doing the trial work. The varieties evaluated included: Entry # Variety 1 Sephia (Galia type) 2 Tirreno (Italian netted cantaloupe) 3 Rawan (Ananas type) 4 Rowena (Ananas type) 5 Migdal (Galia type) 6 Magnificenza (Italian netted cantaloupe) 7 Kenza (Charentais) 8 Karameza (fully netted cantaloupe) Preliminary data will be discussed in this article. Statistical analysis of all the data has not been concluded and therefore only treatment averages are reported. Yield: One of the criteria that was set for the variety trial was that the fruit size needed to be between 2 – 4 lbs. At Meig’s Farm Magnificenza, Sephia and Kenza produced fruit that varied in weight between 3.28 and 3.96[Read More…]



With the start of pumpkin harvest, it is a good time to review important considerations for harvest and postharvest storage of pumpkins and winter squash (butternut, acorn and hubbard squash etc.). First, pumpkin and winter squash should be harvested fully mature to reach their optimal quality and fulfill their potential for long shelf lives. Characters indicating fruit maturity include loss of rind surface gloss, ground spot yellowing, and hardening of the skin to the level that it is resistant to puncture with a thumbnail. Except for some striped varieties, mature fruit should have solid external color. If fruit have to be harvested pre-mature because of plant decline, these fruit won’t store as well as mature fruit. The best practice is to harvest the fruit as soon as they are fully mature and then store under proper conditions. If mature fruit are left attached to the vines, it increases the chance[Read More…]
