Last week I had the opportunity to attend and speak at the Weed Science School. It was an interesting day of learning, discussion, even reflection. Dr. Amit Jhala, Weed Science Specialist, did a really nice job of organizing the day and creating opportunities to hear from University, Industry, and Nebraska Dept. of Ag (NDA) speakers in addition to providing hands-on activities. While dicamba was a topic that was discussed, we didn’t hear about EPA’s ruling till the following day that the RUP products for soybean will be re-registered. Tim Creger with NDA shared that 6 other dicamba products, most with pre-mixes, will be registered this year. He also shared there are 40 ag labeled dicamba products that are not restricted use pesticides, and as long as they aren’t registered for soybean use, he doesn’t anticipate they will become restricted use pesticides. Comparing NDA claims from 2017 to 2018, they received 95 claims (24 investigated due to lack of resources) in 2017 compared to 106 (50 investigated but only 31 resulted in full investigations due to desire of the person filing the complaint) in 2018. Of the 106 claims in 2018, 17 were non-ag related.
In last week’s column, in sharing about fall burndown apps, I had mentioned that 60% ofmarestail (horseweed) in Nebraska germinated in the fall. An updated number of 90-95% fall germination for Eastern Nebraska was shared. This once again emphasizes the importance of considering fall apps for fields with marestail pressure.
Dr. Kevin Bradley from University of Missouri shared on 7 points he’s learned from 15 years of researching waterhemp. They included: Never underestimate waterhemp (I’d say the same for palmer); Era of simple, convenient, quick control is over; Use full herbicide rates and pre-emergence herbicides with residual; Overlap pre + post applications (which we also see with palmer-put that post on a week earlier than you think you need it); Glufosinate, dicamba, and 2,4-D may work now but they’re tools being abused; New traits won’t solve the problem; and Get rid of herbicide-centric way of thinking-we need an integrated approach. He thought he was sharing something shocking in that last statement, but I’d say several of us seek an integrated system’s approach to what we do, including weed management. So ultimately, herbicides aren’t the answer for weed control and we need to be thinking about management from a system’s perspective including crop rotation, use of cover crops, residue management, seed destruction, etc. Especially as from the industry perspective presented, it takes an average of 12 years and average investment of $250 million for a new chemistry to be developed. They are seeking chemistries now that work on specific sites of action (how targets within plant) within the mode of action (specific group or chemistry number).
On November 14th, we’re hosting a Farm/Ranch Transition workshop at the 4-H building in York. This is the closest location for our area. The workshop will focus on the needs of the “sandwich generation” between parents who still own land and children who might want to join the operation, on whom farm/ranch transition and transfer often falls. The Gen2, or Sandwich Generation, will learn how to communicate with family to understand the transition and practice asking difficult questions. Legal topics will include elements of a good business entity, levels of layers for on-farm heirs control and access, and turning agreements into effective written leases. Joe Hawbaker, estate planning attorney, and Allan Vyhnalek, Nebraska Extension transition specialist, will share stories and experiences to successfully plan on the legal side. Dave Goeller, financial and transition specialist, will cover financial considerations, retirement, and compensation versus contribution. Cost is $20 per person. If more than two people are attending per operation, the cost is $15/person. Pre-register at (402) 362-5508 or email@example.com for meal count. Funding for this project was provided by the North Central Extension Risk Management Education Center, the USDA National Institute of Food and Agriculture Award Number 2015-49200-24226.
November 15th is the York County Corn Grower Banquet at Chances ‘R in York. Social time begins at 6:30 p.m. with a wonderful meal at 7:00 p.m. We will hear from Nate Blum, LEAD 36, on his international trip. We will also hear from local and state directors. Tickets are only $10 and can be obtained from any of the local Corn Grower directors or from the Extension Office at (402) 362-5508. The winner of the Yeti cooler from guessing plot yields will be announced, and those who guessed need to be present in order to have a chance to win. Plot results can be obtained from the Extension Office. Hope to see you there for a nice evening with a wonderful meal to hopefully celebrate the end of harvest season!
Crop Update: Wheat is mostly in various stages of heading through pollination in this part of the State. The wheat scab risk prediction model (http://www.wheatscab.psu.edu/) was forecasting higher potential for scab in portions of Nebraska last week with a relax in the model this week due to higher temperatures and no moisture. Please keep an eye on your growth stages, the weather, and the model for risk of scab in your wheat.
Don’t have too much in the way of corn and soybean updates other than it’s good to see guys finishing planting and getting herbicide applications down. Waterhemp and palmer range in size from emergence to 4 inches from what I was seeing this past week.
Also a reminder to install irrigation scheduling equipment soon. It’s always easier to install earlier than when plants get larger! Check out this week’s CropWatch article at https://go.unl.edu/n0u0 which shares additional information about ET gage sites; reminders and tips for installing ET gages and watermark sensors.
Wheat and Field Pea Field Days: There are 11 upcoming wheat field days throughout the State, many of them coupled with field pea/pulse/cover crop field days as well. During the field visits participants will be able to learn more about different varieties of wheat, field peas, chickpeas and forages. Depending on the location, field visits will also include demonstrations of other specialty crops (lentils, winter canola, forages, cover crops) and effects that different agronomic practices (planting dates, seeding rates, fertilizer management, etc.) have on crop yield and yield quality.
Besides field visits, the field days will feature indoor sessions with a free lunch, a 30-minute networking session, and brief research updates. Networking sessions will allow participants to meet with seed, processing, and marketing businesses critical to pulse cop industry development in Nebraska. The research updates will include: Production and marketing of pulse crops, Incorporating cover crops in wheat and field pea cropping systems, and Wheat production – management for higher yield and grain protein. Area dates/locations are listed below and all flyers with additional information can be viewed at: https://go.unl.edu/vto8.
