EAB or Native Borer? New Publication Shows the Difference

July 1, 2014

AMES, Iowa — The Emerald Ash Borer is an insect that, in a matter of time, will destroy all ash trees. Because the bug has begun making its way across Iowa, an Iowa State University Extension and Outreach entomologist, in collaboration with an Iowa Department of Agriculture and Land Stewardship entomologist, has written a new publication to help Iowans identify signs of the pest under the bark.

Turfgrass Rust

August 8, 2014

Rust is a fungal disease caused by several species of Puccinia.  All turfgrass species are susceptible to rust.  However, it is most commonly seen on perennial ryegrass and Kentucky bluegrass. 
 
From a distance, rust infected turf has a yellow-brown color.  Close examination of rust-infected grass blades reveals numerous yellow-orange pustules.  Rust can be easily diagnosed by walking across the lawn.  As one walks across the lawn, bright orange spores of the rust fungus rub off onto one’s shoes. 

Control of Foliar Diseases on Tomatoes

July 25, 2014

Septoria leaf spot and early blight are common foliar diseases of tomatoes in home gardens.  Fungal diseases overwinter on plant debris in the soil.  Fungal spores are splashed onto plant foliage by raindrops or splashing water and invade the plant tissue when leaf surfaces are wet.  Rainy weather in spring and early summer favors development of foliar diseases on tomatoes.

Know Your Mycotoxins

October 9, 2018

With the harvest underway throughout Iowa, rain in some parts of the state is stopping combines from securing kernels from the field. Depending on your location, disease pressure might not have been high. However, rainfall patterns  throughout the season, and even over the last several weeks, means we are not out of the woods yet. Ear rots and associated mycotoxins could be problematic as corn sits in the field awaiting harvest.

Iowa School IPM | Integrated Pest Management for Iowa Schools

School IPM programs help schools provide healthy learning environments by decreasing unnecessary or illegal pesticide use, decreasing asthma triggers (cockroach and rodent allergens, dust mites, and fungal spores), and decreasing pest occurrence and outbreaks. School IPM programs focus on pest identification, pest monitoring, prevention, education, and ecologically-based management techniques. Since its inception in 2000, school IPM programs have been documented as cost-effective and long-lasting, when compared to traditional pest control programs.

North Central IPM Center

The North Central IPM Center works to ensure coordination of efforts and resources to enhance IPM development and adoption for production agriculture, natural resources, recreational environments, and residential and public sites.
