A lot of our tests this year at Hundley-Whaley were designed around the control of waterhemp. We are grateful to the Missouri Soybean Merchandising Council for financially supporting two studies that allows us to determine the best waterhemp herbicides on the market along with the best application times for post diphenylether herbicides.

One test includes twenty-six treatments and the other includes thirty-seven treatments. The results have been somewhat surprising. If you have ever wondered which pre-emergence herbicide does the best job of controlling waterhemp - or if you have ever wondered about the best time to apply a post emergence waterhemp control product, then you will not want to miss the 1996 Hundley-Whaley farm tour. Following the tour you should be able to answer these questions.

1. Which post emergence herbicide provided the best control of waterhemp in 1996?
2. Which incorporated and/or pre-emergence herbicide provided the best control of waterhemp in 1996?
3. What application timing and herbicide rate was best for waterhemp control in 1996?
4. Could you have saved money or made more money by knowing the answers to these questions earlier this spring?

LIBERTY LINK CORN: Several studies at the Hundley-Whaley Farm are centered around the use of Liberty and other herbicides on glufosinate tolerant, "Liberty Link", corn. This technology should be available for use on your farm in 1997. We have learned several things about Liberty this year and we would like to share our knowledge with you at the field day. We should be able to answer questions like:

1. Which weeds is Liberty strong on and which weeds are a problem for the compound to control?
2. When should Liberty be applied for best results?
3. Does Liberty fit best in a conventional till or a no-till corn production program?

HUNDLEY-WHALEY TOUR: This years tour is less than a month away. It will be held at the farm in Albany on Thursday, September 5. The first tour leaves at 9 a.m. and tours will go on throughout the day with the last tour starting at 2 p.m.

There are four separate and distinct tours this year. Each tour will carry 1 unit of CCA credit. There is no charge for any event, or the meal, at Hundley-Whaley.

If you are a regular, or if you have never attended a tour, you are welcome. You can go on one tour or all four. We will make every effort to make it worth your time.

ROUNDUP TO KILL CORN? Everyone knows that corn is very sensitive to Roundup- Right? That is a big concern for people applying Roundup to Roundup Ready beans. How much Roundup drift can corn take without damage? Would you guess a pint? Eight ounces? Less? One of the studies at the Hundley- Whaley farm this spring was designed to answer that question. Burrus BX86 corn was planted and grown to 12" tall and then treated with Roundup as a broadcast application. The high rate of Roundup was 16 ounces per acre. We cut that rate in half and continued to cut rates in half until we applied as little as little as 1/8th ounce per acre. We will harvest the plots to see if ultra low rates of Roundup decreased yields but I think you will be surprised at the rate that ceased to cause visual damage to the corn. Come to the field day of September 5 to see for yourself.

Next year we will probably run this study again but with modifications. One change will be to start making Roundup applications earlier, to smaller corn. If you have suggestions on experiments we can run, there is a place on the registration card to note them. I and the planning committee welcome your input.

NEW HERBICIDES: There are a lot of new herbicides just a year or two from being placed on the market. We have always prided ourselves for having them at Hundley-Whaley in time for north Missouri farmers to see them prior to use on their own farm. A few of the new ones are:

• Authority: A new soil applied soybean herbicide by FMC that shows excellent control of waterhemp and grass in this years plots.

• Axiom: A new soil applied product from Bayer that shows good control of waterhemp.

• Balance: A new Rhone-Poulenc herbicide that is soil applied for weed control in corn. It probably won't be available until 1998 but it is one to watch. For the last two years it has provided outstanding control water-hemp and velvetleaf control.

• Action: A new post applied herbicide from Ciba that is death on velvetleaf in corn.

• Raptor: A new herbicide from American Cyanamid. The chemistry of this herbicide is closely related to Pursuit. It looks very good in our trails but it has some of the same weaknesses as Pursuit. Those weaknesses can be overcome with tank mixes though.

VISIT WITH UNIVERSITY AND INDUSTRY REPS: Attending the Hundley-Whaley field day is a great opportunity to visit with a lot of knowledgeable people. State and regional extension specialists will be there along with most of the technical and sales people from crop protection and crop variety companies. I have never yet met any one person who has all of the answers but among the bunch that you will find at Hundley-Whaley, there will be few questions that can't be answered. Come, visit and learn from the experience.
Graves Field Update Another event to take in is the Graves Memorial Field tour on Tuesday, August 27. Extension specialist Rick Bottoms, Bob Chapple and Don Mobley work together to put on this event. This year they have seventy studies and over 2500 plots. These studies include research on nitrogen fertility, corn starter fertilizer, long term use of ammonium sulfate in corn, nitrogen credit to corn following soybeans and fall regrowth in forages. One of the tour stops will be on the long term research addressing soil erosion and different tillage systems in corn and soybeans. There will also be tour stops on corn and soybean diseases, including corn rust and gray leaf spot, soybean seed treatments and soybean cyst-nematodes. Plan to attend the Graves Memorial Field Agricultural Experiment Center Field Day on Tuesday, August 27th at 9:30 a.m. near Corning and I-29. CCA/CEU Units will be offered.
