Ash Tree Issues
Ash flower galls are appearing on the twigs of ash throughout the state. The brown to black “balls” hang in clusters beneath the branch shoots. The galls are due to the feeding activity of the ash flower gall mite (Eriophyes fraxiniflora) and this mite only feeds on the male flowers of ash.

Infected plants were wilting and upon splitting of the lower nodes revealed brown discoloration of the pith. Root and crown rots developing in corn after the seedling stage are usually caused by Fusarium spp. and can be enhanced by injury to the roots or crown, mainly by insect feeding.

Millipedes May Be Responsible for Reduced Soybean Stands in 2020
