In our current research project, “Strategies for Improving Biological Control of Insect Pests for Vegetable Growers Utilizing High Tunnels”, cut flower, pepper, and tomato harvest has started. The cut flowers have been harvested for the past three weeks, since the first of June, while...

This month's weather information from Trent Ford, Illinois State Climatologist, 217-244-1330,  twford@illinois.edu.A mild May wrapped up the 4th warmest spring on record in Illinois and the warmest since 2012. The warm spring added to a very mild winter...

Out in the field, most crops have been off to a good start. There was a week or two of some downtime on planting due to the wet weather, but some of that is starting to resume. Harvest of peas, greens, and other spring vegetables is underway. Asparagus harvest is nearing the end with an early start...

Spring cover crops are mainly now reaching their end.  Many have been incorporated or terminated and either planted into or getting ready too. This is year 2 of my no-till/cover crop tomatoes and peppers in a small garden type area.  This is an extension of a research project from...

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...

I stopped by a large produce grower in my area, Maddox Sweet Corn Farm, and Ted showed me their grafted versus non-grafted heirloom tomato trial. In the photo (photo credit: D. Gucker Illinois Extension 2024), the row of tomatoes on the left and the row on the right are the same tomato variety. The...

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...

Cover crops are always on the move in April.  I said “explosion” because for many overwintering cover crops it is almost that.  Some can grow over 1” or more per day this time of year! Fall Cover Crop Mixtures Here is a quick update on some early fall planted spring...

Crops are responding to warm spring temperatures and increased daylength. The crimson clover cover crop began flowering on March 29 and by April 3 was in full flower and ready to be terminated. In our current research project, “Strategies for Improving Biological Control of Insect Pests for...

Illinois experienced its 2nd warmest winter on record, cooler only than 1932. The mild winter caused perennials to break dormancy and advance phenology weeks ahead of average. While March and April have had their characteristic temperature swings, milder weather has persisted into the spring so far...
