Late spring freezes and severe winter cold regularly causes stone fruit crop losses to approach100%. With this level of irregular cropping, disease management must focus on protecting foliage to ensure a good potential crop for next year, while reducing over wintering spore loads.

Cultivars Sensation, Radiance, Ruby June were early cultivars; followed by Beauty, Fronteras. So far,…Read more about Annual Plasticulture Strawberry Update at Southwest Purdue Agriculture Center[Read More]
In the Midwest, extreme weather events are, unfortunately, regular occurrences, even in extremely unusual times. At this point, though, it just feels like a pile-on.

It didn’t take much for our own Wenjing Guan to convince me to plant some; who doesn’t love to eat fresh strawberries? We planted them back in October and I just peeked at them every couple of weeks throughout the winter,…Read more about Strawberry Observations from an Entomologist[Read More]

See the weed control chapter in the 2019-2020 Midwest Fruit Pest Management Guide…Read more about Spring Weed Management[Read More]
Staying true to global climate trends these days, March 2020 finished warmer and wetter than the 1981-2010 climate normal period. Snowfall across the state was below normal and localized flooding was a common feature. There were 3-to-5 more days than average in March where rainfall was observed (Figure 1). This has led to saturated soils…Read more about Was March any indicator of the next few months?[Read More]
Warm temperatures this week greatly encouraged strawberry growth and development. Some of the early cultivars may have entered the open blossom stage especially if they are grown with the annual plasticulture system in southern Indiana. Open flowers cannot tolerate temperatures lower than 30°F, while popcorn stage flowers (Figure 1) and tight buds may tolerant temperatures…Read more about Strawberry Growers Should be Prepared for Cold Protection[Read More]
