Field Agronomist Introduction

My name is Josh Michel. I'm a new Field Agronomist with Iowa State that will be covering Southern / Southeast Iowa. I grew up on a farm in Eastern Iowa and went to college at Upper Iowa University. I'm currently working on finishing up my Master's Degree in Agronomy from Iowa State University. Prior to being a Field Agronomist, I worked as an Agricultural Specialist for Iowa State with Research and Demonstration Farms. Before Iowa State, I worked for DuPont Pioneer and the USDA. My wife, Sarah and I have 3 children and live in Wapello, Iowa. I look forward to meeting and working with those in my area. Please feel free to call or email me, so that I may be able to serve your needs.

Growing Season Update

Some small amounts of rain have finally provided some drought relief, but unfortunately overall, many fields are still showing moderate to high levels of drought stress. The most recent drought monitor shows that most of Southern Iowa is either in a D1 (Moderate Drought) or D2 (Severe Drought). Recently, parts of Appanoose, Davis, and Van Buren Counties have been upgraded to D3 (Extreme Drought). More information on the drought monitor can be found here

Considering the lack of rainfall, overall the corn crop still looks fair in most areas. Most corn fields are at R4 (dough stage) to R5 (dent stage). However, with grain fill currently happening, this is the time that we don't hot and dry conditions. You can read more here on the impact that drought conditions can have on corn pollination and grain fill. 

Soybeans are continuing to look good despite the limited moisture. Most soybeans are now at R4 (late pod development) to R5 (early seed development). Even though most of the soybean fields seem to be handling the drought conditions fairly well, some fields that have been under severe drought stress may start to see some pod abortions taking place as those plants are trying to decide how many pods they can fill with the limited amount of moisture.

Pastures and alfalfa fields are continuing to show signs of severe drought stress since late spring. Recent small rains and potentially cooler temperatures may help provide some ability for regrowth to happen.

Drought Meetings being held in Van Buren and Appanoose Counties



The drought conditions are causing major concerns for both crop and livestock producers. To help address those concerns, Iowa State University Extension and Outreach will be hosting a free drought meeting at the following locations. 
 
August 9, 1:30 p.m. Roberts Memorial Building, Memorial Building
(20497 Hwy 1, Keosauqua)
August 9, 6:30 p.m. Rathbun Regional Water Association Treatment Plant
(16166 Hwy J29, Centerville)
 
Meeting topics include: crop growth and development under drought conditions, discussion on feeding drought damaged crops, including issues with drought silage, and crop insurance considerations. Weather patterns and drought monitor considerations will also be discussed by the State Climatologist. FSA and NRCS representatives may also be present to share information on assistance their offices can offer.
 
No pre-registration is required, and the meeting is expected to last about 90 minutes.
Starting approximately 45 minutes before each meeting, producers may bring five representative corn stock samples for a quick nitrate assessment conducted on site prior to the start of the meeting or after the meeting depending upon time.
 
For questions about the meetings, please contact:

  • Weed management strategies for 2019 and beyond by Meaghan Anderson, field agronomist with ISU Extension and Outreach.
  • Crop market expectations by Chad Hart, associate professor in economics and extension grain markets specialist at Iowa State.

 
Attendees will also have an opportunity to discuss concerns and ask questions with each of the speakers at their respective tour stops.
 
Registration for the field day starts at 1 p.m. with the field day kicking off at 1:30 p.m. Certified Crop Advisor continuing education credits will be available. This field day is free and open to the public with no pre-registration required.

The Southeast Research and Demonstration farm is located at 3115 Louisa-Washington Rd, Crawfordsville, IA 52621.

Directions to the research farm: Go 1 1/4 miles south of Crawfordsville on Hwy 218, then 2 miles east on G-62, then 3/4 mile north. Watch for signs. 

Pest Management; What you should be scouting for... 

Potato Leafhoppers: For those with alfalfa, don't forget to continue to keep scouting for Potato Leafhopper. The dry conditions can often magnify feeding injury from potato leafhoppers. Here's a good resource for scouting and managing for potato leafhoppers. 

Twospotted Spider mite: Although they are technically not insects, another insect-related pest to be on the look out for are twospotted spider mites. The dry conditions are very favorable for spider mites.

Early symptoms of twospotted spider mite injury appear as small yellow dots or stipples on the lower leaves of the plants. Prolonged feeding causes the infested leaves to turn completely yellow, then brown, and eventually the leaf will die and fall from the plant. As you are out scouting your fields, keep your eyes open for spider mites. If you happen to find them in a field, this ICM article discusses scouting, thresholds, and management options.
