Growth and development in fruit crops is continuing slowly across the state due to cool temperatures and resulting low growing degree day accumulation. It’s been a rough start to spring to say the least. Frost and freeze damage from the April 15-16 events has become more obvious, and there are still risks of freezing temperatures in…Read more about Crop Conditions[Read More]


The earth’s position and movement around the sun welcomed the spring equinox on March 19th, and meteorologists in the northern hemisphere welcomed spring on March 1st.  Unfortunately, the atmosphere – particularly over the midwestern and Great Lakes states – refused to acknowledge those dates to offer us a more traditional spring.  Sure, Indiana’s spring 2020…Read more about Ready for Winter to Be Over[Read More]


Strawberries growing in the matted-row system are in the blooming stage. Open flowers cannot tolerate temperatures lower than 30°F (Figure 1). Strawberry growers should be prepared for the coming low temperatures this week. Row covers (Figure 2) can be effective in protecting strawberry flowers. In our earlier trial, 1.5 oz/sq row covers provided 4-6 degrees…Read more about Using Row Cover or Sprinkler Irrigation for Cold Protection of Strawberries[Read More]


As we’ve talked about previously, once winter chilling is fulfilled, the rate of tree growth and development is largely dependent on temperature. This is clearly evident in the data over the last 10 years (see Figure 1). In 2012, we had an extremely early and warm spring, rapid accumulation of Growing Degree Days, and very…Read more about Spring temperatures[Read More]


The recent spate of cool, wet weather has left one organism happy, Venturia inaequalis, the fungus that causes apple scab. Most of the state just underwent an extreme scab period, and unfortunately, few of us could do anything about it because of the combination of rain and wind. The revised Mill’s table (from http://www.fruit.cornell.edu/tfabp/revmills.htm )identifies…Read more about Apple Scab[Read More]


The horticultural entomology team is happy to report that we’re continuing efforts to support Indiana apple growers by monitoring tree fruit pests and reporting what we find! On April 22, 2020, we placed pheromone-baited monitoring traps for two important tree fruit pests, the codling moth and Oriental fruit moth at the Meigs Purdue Agricultural Center…Read more about Ready, Set, Monitor! Traps are set to detect key pests of tree fruit: Codling moth and Oriental fruit moth[Read More]
