The 2018 Wisconsin Cover Crop Conference will take place on February 27 (9am-5pm) at the Holiday Inn in Steven’s Point. This will be a statewide conference geared toward helping Wisconsin farmers use cover crops more effectively. Many of the presenters will be Wisconsin grain and livestock farmers speaking from experience about what has worked and hasn’t worked in their Wisconsin cropping systems. Barry Fischer, Indiana NRCS Soil Health Specialist and renowned cover crop expert, will be the keynote for the event. A full agenda and registration information is available: http://fyi.uwex.edu/ covercrop/

2017 Wisconsin Oats and Barley Performance Tests Shawn Conley, State Soybean and Small Grains Specialist

The Wisconsin oats and barley performance trials are conducted each year to serve Wisconsin growers. Trials include released varieties, experimental lines from Wisconsin and Midwestern states, and lines from private companies. The main objective of these trials is to obtain data on how varieties perform in di erent locations and years. Growers can use this data to help choose the best varieties to plant, and breeders to decide on whether or not to release a new variety and to select parents to make new crosses. WCM-126

Weed Identification Series, Galinsoga (Quickweed) Mark Renz UW Madison Associate Professor and Extension Specialist, Chelsea Zegler UW Madison Associate Research Specialist

Due to the warm weather last week we thought we would share one more weed ID plant for the season: Quickweed aka Galinsoga. We actually have two species of this plant in Wisconsin, but they both act very similar so we decided to lump them into one category. These species have been historically common in urban areas as well as horticultural fields but I have been getting more and more reports in agronomic fields over the past 3-4 years. Quickweed is a summer annual that grows, flowers and produces seed very fast; hence the name. What makes this plant so unique is seed usually aren’t dormant so seed produced in one year can germinate in the same year. While most germination occurs through June, it can continue through the summer and in some year even into the fall. I actually saw quite a few seedlings last week from our previous warm weather. Check out the factsheet (also attached to the end of the newsletter) to learn about how to ID this species.

The Madison Field Scout Training Classes will be held on the UW Madison Campus from January 2-5, 2018. The course is designed to provide the skills necessary for proper pest identification, crop scouting techniques as well as provide complimentary baseline information for people preparing for the state CCA exam. Additional information such as crop growth and development, pest life cycle, pest damage symptoms and economic thresholds will be covered. Pest control recommendations, although discussed, will not be highlighted in detail during this course. Crops covered will include, corn, alfalfa, soybean and wheat. Click here for the course syllabus. Non-student registration fee is $225/person but does not cover campus parking. Online registration (preferred) for the Field Crop Scout School can be made at the PAT Store. Checks should be made payable to University of Wisconsin-Madison and sent to Bryan Jensen, Dept. of Entomology, 1630 Linden Dr., Madison, WI 53706.

Wisconsin Soybean Variety Performance Trials 2017

Soybean Yield Gaps Through Data Collection

Shawn Conley, State Soybean and Small Grains Specialist

Shawn Conley, State Soybean and Small Grains Specialist

The Wisconsin Soybean Performance Trials are conducted each year with the producer’s needs in mind. Our objective is to give producers the information to select varieties that will satisfy their speci c goals and are most likely to perform best under their management practices.

Dear Wisconsin Crop Producers:

To view the full article, head to the website below>>>> http://www.coolbean.info/library/documents/2017_Soybean_VT_FINAL.pdf

I am embarking on a Region‐Wide Project aimed at generating baseline producer data on current soybean management practices in Wisconsin’s production systems. This project is funded by the Wisconsin Soybean Marketing Board and the North Central Soybean Research Program (NCSRP). The project goal is to identify the key factors that preclude the State’s Soybean Producers from obtaining yields that should be potentially possible on their respective individual farms. The term used for the difference between what yield is possible on your farm each year and what you yield you actually WCM-127

achieve is called a “Yield Gap”. We are therefore asking Crop Producers in Wisconsin to provide us with yield and other agronomic data specific to their soybean production fields. With that data, we will conduct an in‐depth analysis of what on‐farm factors might be causing a Yield Gap on your farms. To date we have collected data from across the North Central soybean production region from a total of 6251 soybean fields, representing 501,837 acres!!! Talk about BIG DATA!!!

Assessment to Determine Adoption of Pollinator Protection Practices Deana Knuteson, NPM Program

The University of Wisconsin is conducting an assessment to determine practices currently being used in Wisconsin to enhance pollinators. We will use this information to direct further research and outreach efforts. Pollinators are defined as any animal that visits flowering plants and transfers pollen from flower to flower, thus aiding plant reproduction. Wisconsin based pollinators include bees, butterflies, moths, flower flies, beetles, wasps and hummingbirds. In Wisconsin, pollinator-dependent crops account for over $55 million in annual production, but at the same time Wisconsin has been at risk for honey bee colony loss. In April of 2016, Wisconsin produced the Wisconsin Pollinator Protection Plan (https://datcp.wi.gov/ Documents/PPPComplete.pdf ) which helps guide plans and practices for Wisconsin landscapes. Questions developed for this assessment are based on this Plan. We are asking you to provide information into this assessment which should take about 20 to 30 minutes. Link to the assessment can be found at: https://uwmadison.

Wisconsin DATCP Pest Bulletin, Nov 9, 2017

The 2017 Wisconsin Soybean Variety Performance Trials are posted and I wanted to give a brief update on the relative performance of RR2Y® versus Xtend® (RR2X) soybean platforms from this growing season. So how did these platforms fare in 2017? Well, the story isn’t quite as clean and straightforward as 2016, when we had record yields across the state.

2017 Weed Identification Series

Galinsoga (Quickweed) Galinsoga is a broadleaf summer annual common in urban areas and in vegetable crops. Seeds can germinate in early spring through summer. Leaves: Opposite leaves typically longer (¾ to 2 ½ in) than wide (½ to 1 ½ in). Blades have toothed/serrated margins with fine hairs. Stems: Can be simple but are usually branched and up to 2 feet tall. Stems are hairy but the degree depends on the species (hairy galinsoga has more hair). Flowers: Small flowers (1/8- 1/4 in wide) are at the end of stalks extending from where the leaf attaches to the stem. Typically, 5 white flowers (which look

like petals with 2-3 lobes) surround yellow flowers. Galinsoga flowers from June to October. Biology: Galinsoga is referred to as quickweed due to its fast growth and because seeds do not have a dormancy requirement and therefore can germinate in the same season they are produced. Similar Plants: Several species of galinsoga are common to Wisconsin including hairy and small flower galinsoga. They can be difficult to distinguish but smallflower galinsoga has smaller leaves, flowers, and less hairy stems than hairy galinsoga. Control is similar with all species.
