The northern and western corn rootworms are well-known insect pests of continuous corn grown in Iowa. Rootworms are beetle larvae that spend the spring and early summer in the soil eating roots of corn plants. Heavy populations of rootworm larvae are capable of severely stunting the growth of corn.
Tulips, daffodils, crocuses, and other spring-flowering bulbs are a welcome sight in spring. Gardeners can also enjoy spring-flowering bulbs during the winter months by forcing them indoors.
We have recently received several samples in the Plant Disease Clinic of apple and pear with severe infections of scab.
