3.Asparagus harvest is winding down. A rule of thumb is to discontinue harvest when the majority of spears are pencil size or smaller in diameter. (Mike Roegge, U of I)

4.In Illinois vegetable crops,the potato leaf hopper is particularly damaging to potatoes and green beans. As it feeds by inserting its stylet into leaves and sucking out plant fluids, it also injects its saliva into the plant. The saliva is toxic to plants, and leaves typically yellow and curl and plant growth is stunted. See the 2013 Midwest Vegetable Production Guide for listings of insecticides registered for use against potato leaf hopper on specific crops. ( Dr. Rick Weinzierl, U of I)

5.High tunnel growers. As discussed last week, next on our list of insect pests to know well are white flies. White flies are tiny, sap-sucking insects that are frequently abundant in vegetable and ornamental plantings. Click here for a detailed bulletin on the pest.
