Research update from Karuna Kafle, master's student working in the Specialty Crops Entomology Lab, University of Illinois Department of Crop SciencesPlum curculio continues to be a serious concern for most peach orchards in Illinois...
WeatherJune began with much-needed rainfall, with most areas receiving 1-3 inches over three days. Temperatures remained consistent at the start of the month, ranging from 70-80°F during the day and dropping to the 50s at night, accompanied by periodic showers and storms across the...
In addition to peach harvesting in the southern part of the region of cultivars like ‘Glenglo’, ‘PF 5D Big’, and ‘Sentry’, sweet corn harvesting started the last full week of June in the St Louis Metro east. Comparatively, the northern part of the region is harvesting peaches in the ‘PF 8...
Peaches hanging in there - On Friday, May 16, tornadoes impacted several locations across Missouri, Illinois, and Kentucky. Many in surrounding areas not directly affected by the...
Apple Fruit SetFor the week of May 19, apples are currently at about 10-11 mm for most varieties this far north. The season is moving quickly and with this growth, some growers have started their first chemical thinning application for the season. I was a bit concerned about...
As of early April, most apple cultivars in northern Illinois had progressed past silver tip and were in early green tip, with some variability depending on the orchard and cultivar. By mid-April (week of April 15), certain varieties such as ‘Ida Red’ had advanced to the half-inch green stage....
A growing concern observed last year was the lack of lateral branches—or “feathers”—on young apple trees, especially in high-density training systems like tall spindle. This can lead to "blind wood"—sections of trunk without productive branches—which can limit yield and canopy development.One...
Overall, the last month has featured typical spring conditions in Central Illinois, with moderate temperatures and average precipitation. However, there were multiple severe weather events on April 2 and April 20 in the area during this period, including one confirmed tornado in Tazewell County,...

Chemical thinning is a crucial step in successful apple production that could be done in May to June, helping to manage fruit load, improve fruit size, and ensure consistent annual yields, especially on cultivars with biennial bearing tendencies. With several options available, selecting the right...
