The last few weeks has been a dark time for our industry. We have lost some of the stalwarts of the fruit and vegetable industries. We remember: George A. Adrian, 95, Indianapolis Thomas E. Roney, 70, Greenfield Gene M. Wild, 90, Zionsville John Hilger, Ft. Wayne Abner J. Horrall, 85, Bicknell While these folks came[Read More…]

One of the first and most important parts of a good insect and mite management program is the application of an early season oil spray to control European red mites, San Jose scale, and several species of aphids.

A number of growers have experienced increasing problems with woolly apple aphids over the last several seasons. Part of the reason for the increased populations may be related to the changing spectrum of insecticides you are using to control other pests.

There are a number of different types of pheromones, but the most common type is the sex pheromone. Usually the females will[Read More…]
As the spray season approaches, it is good to remember the profound impact water quality has on the performance of pesticides used by fruit growers. Purdue Pesticides Program recently published a guide, The Impact of Water Quality on Pesticide Performance PPP-86, available at the Education Store, 1-888-EXT-INFO or www.extension.purdue.edu/store/. I highly recommend this guide to[Read More…]
The results of a historical primate behavior analysis suggest that species with fruit-filled diets evolved larger brains. A popular theory among evolutionary biologists is that we have our sociability to thank for our big brains. This “social brain hypothesis” suggests that the mental effort involved in interacting with others eventually increased our cognitive capacity. However,[Read More…]
Following a very early warm-up, temperatures cooled off the middle of March slowing crop development and bringing us back closer to normal. In southern areas, peaches are in full bloom, but only just showing a little pink in more northern areas. Apples are still in tight cluster and probably at least 10 days from full[Read More…]
Spring is in the air, and soon, ascospores, basidiospores, and conidia will be as well–Now is the time for disease management! Not sure what to spray or when to spray it? There is always the Midwest Fruit Pest Management Guide, available at: https://ag.purdue.edu/hla/Hort/Documents/ID-465.pdf For those of you who would like a different approach and layout,[Read More…]
