Upcoming Commercial Pesticide Applicator Training

By Brooke Garcia & Frannie Miller

Upcoming Commercial Pesticide Applicator Training

Date: November 12-14, 2019 in Salina, KS – Webster Conference Center

Website: https://conferences.k-state.edu/commercialpesticide/

Objective: The objective of this training program is for the Kansas State University Cooperative Education Service to provide a broad, practical training program and to help Kansas commercial pesticide applicators meet the requirements for renewal certification.

ALL commercial certified pesticide applicators are required to accumulate credit hours if re-certifying through training.

In Kansas, there are two ways to receive training for renewal certification: 1) study a manual and pass an examination and 2) attend training courses approved by the Kansas Secretary of Agriculture for required re-certification credit hour (CEU) accumulation. All applicators must now accumulate the necessary credit hours required for the appropriate category/subcategory in which they are certified. If you have not accumulated the required number of credit hours (1 core hour and either 3, 5 or 7 pest management hours) and paid the certification fee ($50 per category certified in) to the Kansas Department of Agriculture (KDA) by the expiration of your current certification, you must re-exam to obtain certification.

Questions?
If you have questions regarding the renewal requirements, please call the Kansas Department of Agriculture at 785-564-6688. To view your current certification credits, go to: https://www.kellysolutions.com/ks/applicators.
If you have questions concerning this training program or if you are interested in the additional training programs that the K-State Research and Extension Program has to offer, please call Frannie Miller at (620) 241-1523.

Are you using the right gloves for pesticide safety? And a new resource to translate safety info into Spanish

With pesticides, usually we are thinking about the active ingredient that targets the problematic insect, weed, or disease. But did you know that the different “carriers” in the formulation can affect applicator safety, too?

Here is a quick article that summarizes some of the key points of selecting the right gloves for applicator safety:

If the Glove Doesn’t Fit (the job!), You Must Quit

 

Speaking of pesticide safety, the EPA recently announced a new program to help translate information into Spanish.

Large Patch Evaluation Study Update

By: Manoj Chhetri

With temperatures cooling down and days being shorter, we are already starting to see warm-season grasses, including zoysiagrass, going to sleep. At the Rocky Ford Turfgrass Research Center, located in Manhattan, KS, we have shut down the irrigation in warm-season plots.

Our zoysiagrass in the large-patch tolerant breeding plot is not cooperating with us as much as we wanted. We inoculated the field in mid-September with fresh Rhizoctonia pathogen and kept the field pretty wet to encourage fungi to flourish. However, to our dismay, we did not see much of the disease activity, except in a few poor drainage spots. With disease research, it is the type of research where we want disease pathogens to have no mercy on us. We are impatiently waiting for spring, which in fact is a more favorable time of the year for large patch activity.

We are hopeful that we have at least one or two new zoysiagrass progeny that possess greater large patch tolerance. Again, it is hard to make comparison and evaluate when we don’t have disease pressure. So far, we have narrowed down to 10 best progeny out of 60. On the positive note, we have seen more disease pressure on our non-selected progeny than in our top-ten selected progeny. This tells us that we did a good job on choosing those ten-best progeny.

This project is aiming to develop a large patch tolerant zoysiagrass that can significantly reduce cost on fungicides and protect the environment. It is a collaborative project between Texas A & M and K-State University.

Preparing for the Cold Season Ahead

By: Brooke Garcia

It seems as through Kansas only knows how to jump, skip, or hop into a new season. We had a small taste of Fall weather, and it is now feeling a lot more like winter. The landscape has most likely dramatically changed in the last few weeks. If you overseeded your lawn, you’re hopefully enjoying the green color of the freshly germinated seed. Several garden weeds are dying back. Mums are flowering and showing off their color. Maples, as well as other fall foliage, are showing off their beautiful fall color as well. Visit the Horticulture e-Newsletter for more information on some of the reasons these trees have color.

While some of our favorite landscape items are full of life and color, there are a handful of plants in the landscape that have entered dormancy or have died back. Not only have they lost their leaves or blooms, they may be ready for cutbacks. If you had annuals planted in the landscape, they may have recently died back from the recent freezing temperatures we experienced throughout Kansas. They will need to be removed from the landscape. Fall is an important time to perform a garden clean-up. For more specific information on perennial cutbacks, visit the Horticulture e-Newsletter for their recent post.

Want to know what to do with all of those leaves? Here is a previous blog post about Mow-mulching fall leaves.

It is also not too late to plant Spring-Flowering Bulbs. As long as the soil
temperatures >40 degrees Fahrenheit, the spring bulbs should continue to develop. For more information, read the article “There is Still Time to Plant Spring Flowering Bulbs” on the Horticulture e-Newsletter blog.

After you’ve completed cutbacks and bulb planting, mulching is an important task to be completed in the Fall. Not only does it “freshen” up landscape beds, it helps to retain soil moisture and protect the roots of plantings for the winter months ahead.

In addition to all of these Fall tasks, it is also important to consider general clean-up tasks that include:

  • Power-washing exterior of buildings and/or structures, as well as driveways or sidewalks
  • Container/planter re-fresh: Remove dead plantings from containers or planters. Empty used soil out of containers and store containers in a warmer/dry place. This can reduce cracking and general wear/tear.
  • Remove dead weeds from landscape
  • Remove fallen leaves/debris within landscape, and add to compost bin
  • Unscrew hose, and place hose-bib covers over hose bibs in preparation for freezing temperatures
  • Cover or store exterior furniture. Store cushions, umbrellas, etc.

This may seem like a lot of fall tasks to consider, but they are all important tasks to keep your landscape(s) looking beautiful during the fall and winter seasons. Hopefully this helps you develop your Fall clean-up program or builds onto an existing clean-up program for your landscape and garden.

Research in progress: zoysia seedhead suppression

(Megan Kennelly, KSU Plant Pathology)

I was out looking at our zoysiagrass breeding plots the other day and in a couple of plots I saw some seedhead development:

 

This was unusual, as we typically see this in spring, and it’s probably just a unique physiology of these couple of breeding lines. Anyway, this observation prompted me to mention that we are continuing KSU’s work on zoysiagrass seedhead suppression. You may have seen the articles about the prior excellent work by Dr. Hoyle and colleagues which you can view here:

Suppressing Meyer zoysiagrass seedheads

and here (academic peer-reviewed version)

https://dl.sciencesocieties.org/publications/cftm/abstracts/4/1/180012?access=0&view=pdf

We are following up on this work with additional trials to hone in on the biology and management of seedheads, fine-tuning application timings of ethephon. Stay tuned for results in the coming 1-2 years as we collect data. The project team members are PhD student Manoj Chhetri, Jack Fry, Jared Hoyle, me, and Aaron Patton (Purdue). The project is funded by the GCSAA, Heart of America Golf Course Superintendents Association, and Kansas Turfgrass Foundation.

Sharp drop in temperature may be a cause for concern in trees

Western Kansas experienced an extremely sharp drop in temperature recently. Temperatures in some areas of northwest Kansas were near 80 on Wednesday and dropped to near 20 or lower Friday morning. Unfortunately, trees were not hardened off before this happened. In other words, they were not ready for these cold temperatures.

What does this mean? You can read the whole article here in the Horticulture News. Go to this page and scroll down partway:

Cooler weather brings the return of the Mesonet Freeze Monitor

(Chip Redmond, Mary Knapp and Dan Regier; Weather Data Library/Mesonet)

Cold weather is making its appearance with frost advisories issued this last weekend and freeze warnings this week. The average freeze date in northwest Kansas is as early as the last week in September. However, southeast Kansas does not usually see freezing temperatures until the end of October. Average dates for the first occurrence of 24-degree F temperatures are even later.

Fall Fertilization and Turf Tips

(By Jared Hoyle, KSU Turfgrass Research and Extension)

Dr. Bill Kreuser, Assistant Professor and Extension Turfgrass Specialist, at the University of Nebraska – Lincoln posted some great information on fall turfgrass fertility and some other fall turfgrass tips.

Dr. Kreuser quoted, “Fall is arguably the most import season for turfgrass managers. While we’re busy preparing for a new growing season in spring and trying to survive stressful conditions in the summer, fall is the time to recover from summer, renovate, and prepare for winter. It’s a season of seeding, cultivation, weed control, and fertilization. While fall is still widely considered the most important time to fertilize turfgrass, the fertilization recommendations have evolved over the past decade.”

I couldn’t agree with him more.  There has been lots of recommendations evolve over the years and just because “this” is way it has always been done doesn’t mean it is right.  See what Dr. Kreuser has to say and check out the links below.
