With weird weather often comes weird physiological disorders (on top of our summer fruit rots). Often confused with hail injury, disease or insect damage, these physiological disorders are marring the appearance of many apples. Symptoms of bitter pit include circular or even irregular sunken spots on the fruit surface, beneath brownish or streaked dead regions…Read more about Physiological Disorders[Read More]


With harvest around the corner for many fruit crops, I thought this would be a good time to remind readers about our email lists. Various forms of social media is used by just about everyone in today’s society.  While Facebook and Twitter are much more commonly used than email, there is still a place for…Read more about Purdue Fruit and Vegetable Grower Mail Lists[Read More]


Although PristineTM was selected in 1982, its history goes back to the early days of the PRI breeding program. From an original cross of Rome Beauty with Malus floribunda 821, selections and hybridizations were made incorporating Golden Delicious, McIntosh, Starking Delicious  and Cazumat along the way. The cross that resulted in PristineTM was Coop 10…Read more about PristineTM Apple[Read More]


ReTain (AVG) is a plant growth regulator that blocks the production of ethylene. When ReTain is applied to apple, several ripening processes are slowed, including preharvest drop, fruit flesh softening, starch disappearance, and red color formation. In order for ReTain to be effective it must be applied well in advance of the climacteric rise in…Read more about Timing Retain Sprays[Read More]

Preharvest drop refers to the process where fruit fall from the tree prior to harvest. Not all apple varieties are affected, but with some, such as McIntosh and Pristine, pre-harvest drop can be extreme. Several growth regulator materials are available to growers to help reduce pre-harvest drop. These materials are often referred to as “stop-drop”…Read more about Control Of Preharvest Drop with NAA[Read More]


Early grapes are just beginning to soften and color (veraison). Summer raspberry harvest if winding down and fall bearing types are flowering. Blueberry harvest continues. Japanese beetle numbers continue to be relatively high in the Lafayette area. Peach harvest (for those fortunate to have a crop) has begun. Early apple cultivars are approaching harvest.


Making the decision on when to harvest can be a very tricky and complicated issue. The longer you intend to store the fruit, the more precise your timing needs to be.  For summer apples, most growers only intend to store fruit until their higher quality fall apples come on stream, so storage times beyond a…Read more about Determining Apple Maturity[Read More]
