Herbicide Resistant Weeds Workshops Slated for Maryland, Virginia, and Delaware
A series of half-day workshops will be held in Maryland, Delaware and Virginia this winter for farmers interested in learning about the problems of herbicide resistant weeds and how to manage them. Hosted by University of Maryland Extension in collaboration with Virginia Tech and University of Delaware, these workshops are designed to equip farmers with the knowledge to improve weed control on their farms.
Farmers in the mid-Atlantic area are starting to see the impact of herbicide resistant weeds on their crop yields. With many problematic weeds now found throughout the region it is essential that farmers learn the key management strategies to control these weeds.
Sessions will cover integrated weed management tactics; palmer amaranth, common ragweed and marestail control strategies; and developing a weed management plan. There is no charge to attend and lunch will be provided. Pesticide (commercial and private) and CCA continuing education credits will be offered.
Workshop locations and times are listed below. Please RSVP to the respective meeting location to provide an accurate meal count.

Dicamba Training Opportunities
If you intend to apply Engenia, Xtendimax, or FeXapan this year, you need to complete the annual dicamba specific training requirement in addition to being a certified pesticide applicator. In Virginia, this training is conducted by the registrants (manufacturers), but can also be completed in another state including registrant training, state mandated training, and state approved training. Both in person and online training is acceptable. Training is not product specific; you do not have to take the training from the registrant of the product you apply.
Make sure to document your training.
Here are links to find a training event near you or complete online:
Please note that some some events require pre-registration.
The following links are under revision for 2019 but will be useful shortly:

Walk Your Fields
For greater soybean yields, one of the best things that you can do is walk your fields. Many problems reveal themselves during the summer. Actions taken or not taken can be very noticeable. By walking fields, we can see what’s working and what’s not working. Certain problems can be solved, some cannot. For those that cannot be solved this year, we can do better next season by understanding why we have the problem. Therefore, a review of how to diagnose your crop will likely beneficial.
A few years ago, I published “Troubleshooting The Soybean Crop“. Although a little dated, most of the information is still good. This publication will guide you through how to go about diagnosing problems, includes a vegetative- and reproductive-stage outline with lots of photos, and also includes a sample crop scouting and diagnostic form. You can download a view a PDF copy, or contact me – I still have a few hard copies left. By following some general guidelines, one can become quite good at diagnosing problems. Below is a summary.
First, document everything! Memories tend to fade. We often forget or overlook details. You can document by taken notes (many phone apps or iPad/tablets work well for this). Make a recording. Take pictures – this is especially useful when you need help – and send those photos to others.
PRELIMINARY FACT FINDING. You can obtain plenty of information before you even get to the field. Although I call this preliminary (as if you’ve not seen the problem), you may need to go back to the office to refresh your memory of what you did. Information that can be acquired beforehand or back in the office includes:
- Cropping History
- Soil Information
- Pest Management Information
- Tillage and Other Cultural Practices
THE FIELD VISIT
- Take all materials and equipment needed (e.g., phones, paper, shovel, plastic bags, soil probes, etc.)
- Windshield/Whole Field Investigation
- Above-Ground Inspection
- Take Appropriate Plant or Soil Samples
- Equipment Check
- Interaction with Others
- Document Everything!
ANALYSIS OF DATA AND FINDINGS
- Look-Alike Symptoms
- Interacting Factors/More Than One Problem
DRAWING A CONCLUSION. Review the facts and data. Eliminate unlikely causes. Validate likely causes. You may be able to drawn a conclusion in the field, but lab analysis may be needed.
FOLLOW UP. Revisit the field. If you took corrective action, did it work? Why or why not?
This is a very rough outline of the guide. Again, if you want a hard copy of Troubleshooting The Soybean Crop, contact me.
