AG NEWS TODAY

Tree-killing pest confirmed in Chickasaw, Franklin and Jones counties AgDM Newsletter-August , Keely Coppess, Julie Tack,

Laura Sternweis

DES MOINES, Iowa – Emerald ash borer has been confirmed in Chickasaw, Franklin and Jones counties for the first time, bringing the total to 69 coun-ties in Iowa where this invasive insect has been detected.

Insect samples were collected from New Hampton (Chickasaw County), Hampton (Franklin County), and Anamosa (Jones County). Officials with the Animal and Plant Health and Inspection Service (APHIS) of the U.S. Depart-

ment of Agriculture (USDA) confirmed these samples positive for EAB.

EAB is a non-native beetle that attacks and kills ash tree species. Adult bee-tles lay eggs on the bark of ash trees. Once the eggs hatch, the larvae bore beneath the bark and begin feeding on the water and nutrient-conducting

tissues. Infested trees typically die within two to four years.

Ash trees infested with EAB can exhibit canopy thinning, water sprouts from the trunk or main branches, increased woodpecker activity, serpentine (“S”-shaped) galleries under the bark, vertical bark splitting and 1/8 inch D-

shaped exit holes.

The spread of EAB is accelerated by transport of infested wood products such as firewood. People are reminded to use locally-sourced firewood to

help reduce the spread of EAB.

EAB was first discovered in southeastern Michigan near Detroit in 2002, and has now spread to 35 states. This exotic pest was first detected in Iowa in

2010.

At this calendar date, the treatment window for soil-applied preventive treat-ment measures (soil injection, soil drench, or granular application) and ba-sal bark sprays has ended. Trunk injections can be done now through the

end of August if a landowner is interested in protecting a valuable and healthy ash tree within 15 miles of a known infestation.

Thistle caterpillars, late season crop diseases and crop development will highlight the fall field day at Iowa State University’s Northern Research and Demonstration Farm Sept. 5, 2019

“Farmers and agribusiness will hear the latest on thistle caterpillar and tar spot of corn,” said Paul Kassel, field agronomist with Iowa State University Extension and Outreach. “Thistle cater-

pillar and tar spot are two new pests that have raised questions for Iowa producers in 2019.”

The program begins at 9:30 a.m. with Matt Schnabel, Northern Research Farm superintendent, giving a review of the growing season and a discussion of summer activities.

Erin Hodgson, associate professor and extension specialist in entomology at Iowa State, will dis-cuss insect issues that occurred in Iowa crops this summer, including thistle caterpillars, soy-bean gall midge and soybean aphid management for 2019.

Alison Robertson, professor and extension specialist in plant pathology and microbiology at Iowa State, will talk about late season corn diseases. Robertson will also discuss a new corn leaf dis-ease present in Iowa in 2019.Alison Robertson, professor and extension specialist in plant pathol-ogy and microbiology at Iowa State, will talk about late season corn diseases.

Paul Kassel will discuss the impact of the late planting and summer growing conditions on crop development.

Angie Rieck-Hinz, ISU Extension and Outreach field agronomist, and Karen Wilke, coordinator with The Nature Conservancy, will discuss cover crop management for 2020 and some local fund-ing options.

The farm is located at 1040 James Ave., Kanawha – about two miles south of Kanawha on County Road R35.

Registration and refreshments will begin at 9 a.m. A noon lunch will be available. The field day is free, open to the public and includes complimentary refreshments and lunch. An application has been made for Certified Crop Advisor credits.

Late August Heat Is Reminder to Keep Livestock Cool August 16, 2019, 8:16 am | Chris Kick, Jason Ross, Grant Dewell, Jennifer Bentley

The summer heat will return to most of Iowa over the coming weekend and into next week, according to the National Weather Service.

Highs are expected to approach 90 degrees Fahrenheit, and even though that’s cooler than the stretch of hot days the state saw back in July, producers should still prepare.

Each species of livestock reacts to heat differently. However, the common principle is to maintain good venti-lation, provide shade and access to clean, cool water, and limit moving animals during the hottest hours of the day. Swine care Pigs do not have sweat glands, making them especially susceptible to heat stress, according to Jason Ross, di-rector of the Iowa Pork Industry Center at Iowa State University. Swine producers commonly rely on cooling fans and evaporative cooling systems that help the animal to increase evaporative heat loss and stay cool, and keeping the system running at optimal levels is critical during periods of extreme heat. Beef cattle Compared to swine, cattle can tolerate higher temperature at lower relative humidity, because cattle can dissi-pate their body heat more effectively by sweating. However, cattle are more prone to stress when the humidity

rises, and need the same level of care as other livestock. ISU Extension and Outreach published an article in June about how beef cattle farmers should prepare.

Common solutions for cattle include access to clean, cool water, shade and good ventilation. Avoid moving cattle during the daytime and afternoon, when temperatures are at the highest, because the energy cattle ex-pend while moving will cause even more stress.
