Conditions during July were favorable for infections by a couple of fungi that are known to cause ear rots of corn. Observations of Diplodia ear rot already have been made in some corn fields in Kentucky this year. Although conditions…

Earlier this summer, and as recently as last week, I received inquiries from different counties in Kentucky on the control of insects (i.e., rice weevil, lesser grain borer weevil, and Indian meal moth) in stored grains. Now that corn fields…
Soil mites are considered one of the major components of soil arthropod communities, although they are not well studied. Soil-inhabiting mites play an important role in litter/organic matter decomposition in three different ways: (1) direct litter decomposition, (2) organic matter…
The following plant disease highlights from the University of Kentucky Plant Disease Diagnostic Laboratories represent recent sample submissions from field crops, fruit, vegetables, and ornamentals. Diseases diagnosed on agronomic crops during the past week have included southern rust, anthracnose, Diplodia…
Trap counts for major insect pests are provided by the Kentucky IPM Program. Traps are located at the UK Research and Education Center in western Kentucky and the UK Spindletop Farm in Lexington. Below are trap counts for the current…
Fall armyworms (Spodoptera frugiperda) do not survive the winter temperatures of Kentucky and surrounding states, and every year there is a northward migration in the continental U.S. These migrant moths originate from populations that overwinter in southern Florida or southern…
Colby Guffey, Clinton County Ag & Natural Resources agent, sent digital pictures of larvae he found while investigating some unusual symptoms in silage corn. The larvae, which were tunneling in corn stalks, resembled European corn borers but were legless. In…
With the dramatic upswing in fall armyworm moth captures last week in Princeton, sweet corn producers should monitor their late plantings closely. Fall armyworm (FAW) can attack the leaves and, when available, will move to the developing ear of sweet…
Sawflies are members of the insect order Hymenoptera that includes ants, bees, and wasps. The larval stage has a caterpillar-like body that may be brightly marked with stripes or spots. Some species change significantly in appearance as they grow, making…
Late season caterpillars are out in full force. Many use camouflage or secretive behavior to avoid predators. In contrast, stinging caterpillars have brittle, hollow spines connected to venom glands. These spines easily penetrate and break off in the skin. Then,…
While fall brings wonderful weather, it also signals the start of the insect invasion period. One of the early-fall home invaders is the brown marmorated stink bug (BMSB) which clusters on the sides of buildings searching for entry points throughout…
Diseases diagnosed on agronomic crops during the past week have included Fusarium ear rot on corn; rough leaf spot, zonate leaf spot and sugarcane aphid on sweet sorghum; black shank and frogeye leaf spot on tobacco. On fruit and vegetable…
