Producers: please remember to check your private applicators expiration date

Please remember to check the expiration date on your private applicators license.  Now is a great time to take the test and renew your licenses for another  5 years.  By having your license current it allows you to have access to a broader range of herbicides and insecticides. What we don’t want to have happen is for you to arrive in season looking for a specific product and being unable to purchase it due to an expired license.

The DATCP (Department of Agriculture Trade Consumer Protection) website is an pesticideexcellent source for more information on applicator testing and training. For more information on testing and training, including downloadable training manuals visit http://ipcm.wisc.edu.pat/ . A complete training schedule is available at http://www.uwex.edu/ces/cty/ .

Certification Process

Purchase private applicator training materials and inquire about applicator certification training from your local UW-Extension county agent. Visithttp://www.uwex.edu/ces/cty/ for a list of agents.

A schedule is posted on the UWEX Pesticide Applicator Training website — http://ipcm.wisc.edu/pat/events/ . Training materials cost $30 per applicator category and $10 per subcategory.  County UW-Extension agents oversee private applicator certification exams.  Certification is good for five years.  For more information, call (608) 224-4548.

Problem Weed: Little Christmas Trees

equisetumI have been asked by a lot of growers on how to get rid of the “little Christmas trees” in their soybeans and corn fields. This weed has a lot of common names; little pine trees, Christmas trees, scouring rush, horseweed and others. I refer to it as Equisetum.

This weed is extremely difficult to control. There are very few if any herbicide options available.  Purdue mentions a few that have activity but none that have control.  This plant is very primitive, it is not a broadleaf or a grass. Relatives of this species were around at the time of the dinosaurs. This plant can reproduce via underground stems and by seed.equisetum drawing

If possible keep it mowed off to inhibit reproduction and spreading. Tillage can spread this plant to some degree.  Please let us know if you have any questions on this troublesome weed.

Following are some datasheets that give you more insight on this weed and how to manage it.

Second crop Alfalfa — Light PLH and Alfalfa Weevil pressure found

We finally have a nice sunny morning, and I’m out scouting some second crop Alfalfa.  I figured we should get it   scouting second crop done today with the forecast for storms tomorrow.    The Alfalfa is at 4 to 6” tall.  We found low levels of PLH (potato leaf hopper) and Alfalfa Weevil.    But with warmer temperatures these pests can advance rapidly, so I would encourage you to keep a close eye on your second crop. 

I have included a few pictures from this morning.  For some reference materials to help you identify these pests, click on the following link  AlfalfaInsectMgt by Craig SaxePotato-Leafhopper-Adult

Corn at V2 and V3 — Time to consider pre-sidedress nitrogen testing

Our field corn is already hitting V2 and V3 in area fields. Time to be looking at what additional nitrogen is needed to make Grace sampling 5-20-15 #2target yields. Our Agronomy intern at Galesville / Arcadia, Grace Curran, was out with me today looking at area fields and pulling some pre-sidedress nitrate tests.

Below are some links to information on what this test is and why you should be looking at it.
