In our current research project, “Strategies for Improving Biological Control of Insect Pests for Vegetable Growers Utilizing High Tunnels”, the second treatment or strategy besides establishing and overwintering cover crops is growing a row of cut flowers within the same high tunnel as...

It is starting to be potato leafhopper season in Illinois. Potato leafhoppers are pests on a variety of crops (fruit, vegetable, ornamental) and they do not overwinter here, so they migrate in from the south as the weather warms up. Potato leafhoppers feed by inserting their needle-like mouthparts...

Apples are up to 5mm fruit size and thinning of fruitlets is in progress. Prior to “traditional...

We have been on the typical March roller coaster for weather lately.  We have generally been fairly mild but have gone from a few days around 80°F to some morning lows in the upper 20s.  We have still been relatively dry for the month of March with only 1.54” of rain to date (as of 3/25/...

Our warm overall winter and above normal February temperatures signaled plants to break dormancy early, putting many of our crops, especially peaches, at risk of freeze damage. The potential for frost/freeze events from mid-March through mid to late April is typically high, putting peaches in...

Based on research by Wallis and Cox with Cornell University and with support from BASF, an Apogee Sec. 2(ee) Recommendation for Illinois apple growers is now...

Plum curculio has been a growing problem in most peach and apple orchards in Illinois. A small weevil, laying eggs inside the fruit, is quite destructive to the peaches and apples. Traditionally, we have diagnosed this problem through the crescent-shaped scar that appears on fruit as a result of...
