President's Message

As we enter the 2016 year, we are seeing some dramatic changes in agriculture. While we will discuss some of these trends at our Grower Meetings, I would like to address a few matters in this letter.

  1. RUMORS -There have been numerous rumors saying that TH has been sold. This is FALSE! We are still an independently owned, Wisconsin-based corporation. It is business as usual at TH this year, with the same dedicated staff as always to serve your needs.
  2. FERTILIZER - Prices continue to drop. If you haven't purchased any fertilizer yet, I would hold off for a while, as I feel the trend will continue to move downward. I know a number of fertilizer suppliers are saying that logistics will be a problem come spring. If you feel that you absolutely need to book your fertilizer now, make sure you get price protection to guard you in case of future price drops. TH never purchases fertilizer early so that we never get caught upside down. Keep in mind that we only supply fertilizer in truckload lots.  Please give us a call when you are ready to purchase and we may be able to save you some money.
  3. CREDIT - I know many growers are having challenges in getting their operating loans in place for the 2016 season. Depending on the products that you use, however, a number of the basic companies will allow you to finance their products through John Deere Finance. Often the interest is delayed or at very low rates. We do encourage you to have your financing in place for the 2016 growing season. TH has an arrangement with the banks: They don't sell chemicals and we don't loan money.
  4. CHEMICALS - More and more products are coming off-patent and, because of the competitive nature of the business, prices have dropped significantly and may continue dropping, even into planting season. While we are a distributor for the basic chemical companies, we also work with the generic and off-patent companies. This gives you additional choices for your input costs. I will be putting together a special cash-and-carry price list for the off-patent products. This list should be available the first week of March.

In conclusion, thank you for your interest in and support of TH. It is appreciated! After over 34 years in business, we feel like we know the ups and downs of working in agriculture. We are committed to helping our customers not only survive this downturn in the agricultural sector, but also to come back stronger than ever.

Best Regards,

Robert L. Zimpel

Drones and Agriculture

Scouting fields on foot may someday be a thing of the past. Soon- perhaps sooner than we think- UAV's (Unmanned Aerial Vehicles), otherwise known as drones, may be doing our scouting for us.

Over the last couple of years, interest in UAV use in agriculture has, one might say, taken off. Incredible interest has developed in these small, mobile, aerial vehicles that have the capacity to take high quality photos and videos of fields from above, providing an altogether different perspective than is able to be achieved from the ground. From these higher vantage points, farmers are quickly able to discern areas of disease, drought, and insect pressure in their fields. This in turn allows them to create a much more accurate irrigation and pesticide application plan than they are capable of doing from traditional scouting reports, something that is better for the environment and for costs. Some hope, too, that before long UAV's will be utilized in the pesticide application process itself, providing pin-point accurate applications in the field while keeping humans safely out of the application zone.

Currently, various government agencies are working alongside local farmers and UAV manufacturers to develop regulations that will clarify just what the role of UAV's in agriculture is to be. Opponents of their use cite privacy invasion as the main reason for disallowing UAV's. Proponents argue that the potential revenue to be derived from implementing UAV's is too much to pass up, and that foreign countries are already leaps-and-bounds ahead of the U.S. in utilizing this helpful technology.

Our perspective here at TH is that UAV's will soon become standard features in our precision ag era. As a way to get a jump on this up-and-coming technology we recently invested in a small UAV that we will be doing trial work with this upcoming season. We will be keeping you posted throughout the year on our progress and invite you to submit any questions you may have about UAV's and their place in your programs.

Legacy Seed Dealer Kickoff

Recently we attended the Legacy Seed Dealer Kickoff meeting. There have been a lot of changes within the seed industry this year. One small company that stands out is Legacy Seed, who had impressive growth again this year, mostly in alfalfa and cover crop sales. What is impressive is that a small regional company has put together a lineup that’s hard to beat. Legacy has added 21 new genetic corn families, including 8 new conventional hybrids from 80 to 112 days. I would say no other company has added this many.  That means some of your old favorites may be gone or going away soon.  There is some new traits to talk about from Agrisure (Syngenta)  the Artesian, which is drought tolerance and the Duracade which gives more rootworm traits.  We would also expect to see a $10-20 per bag increase this year, mostly due to the cost of production.

For Beans Legacy has 6 new varieties including a 2.0 food grade option. Most of the talk is about traits, by 2016 new herbicide trails should be released including Monsanto’s Xtend Beans (tolerant to Banvel) and Dow’s Enlist Beans (tolerant to 2-4D) and joint ventures between Syngenta and Bayer for HPPD (Callisto, Balance) to be stacked with Liberty at some point.  My thoughts go back to when glyphosate tolerant beans first came out, the learning curve was steep. Seed supply looks great, and pricing should be similar to past years.

Legacy is proud to be the only privately owned alfalfa breeding program left in the US, most of the research gets done here at Janesville WI.  They recently introduced the Aphanomyces Race 2 (APH2) resistant variety, which will significantly help around the state. They also released a new high digestible variety for 2014. Remember with all the winter-kill stocks are extremely low and there will be a price increase of $20/ bag.

Let’s not forget cover crops; Legacy’s Earth Builder Brand has a complete lineup for you to choose from. Including the Pile Driver radish and two new nematode control radishes, this will work for potatoes and carrots.  These radish’s cost less than chemical fumigants, and do not destroy soil life, and rather build soil health. That’s enough for now, but let us help you with your seed purchases for 2014.

Soil Fumigation Regulations


Time for soil fumigation, but keep in mind we have a few more changes that take affect this year. The changes have been introduced by the Environmental Protection Agency (EPA) require new safety measures for agriculture workers and those who live, or come near fields that are fumigated.

The changes impact workers, growers and land owners all over the United States this fall. The fumigant labels have become much longer. Applicators and growers will need to read and understand the new labels prior to fumigant use this fall. Advance planning is needed before starting soil fumigation because additional preparation of intended soil fumigated sites.

In 2013 applications will include all of the 2011 changes and also incorporate Buffer Zone requirements. The buffer zones are mainly for non-handlers and last for a minimum of 48 hours. Buffer zones size will be determined by application rate, field size, application equipment, and methods. In addition the certified applicator must evaluate each site and include in the FMP (fumigation management plan) these parts if applicable: 

•Posting requirements for buffer zones

•Map details for each site

•Difficult to evacuate sites

•Emergency preparedness and response

•Applicator training

•Notice to tribal and state agencies

•Safety information for communities and first responders

I have mentioned a few fumigation highlights but have not been inclusive of all the changes. Please visit EPA’s web site and read all new product labels for information about additional requirements.

Rain, rain, and more rain

As the rain continues to mount, growers are struggling to get the remaining acres of corn and soybeans into the ground in order to have a successful fall. While some fields are under water, others are dry enough to spray pre-plant herbicides on the soil followed by a timely and limited disturbance planting.

With such short time frames to spray and plant, please check that all Mini Bulk containers are working properly by running them before crunch time. Although unlikely, if there are any problems with the motors, pumps, etc. please call the office at 715-335-6343 immediately and we will usually fix the problem within the hour you call, free of charge.  The last thing we want is for you to be waiting on us when you want to spray your chemicals.

Besides headaches, this wet weather brings disease. There are many options to prevent and/or cure disease in your corn, wheat and soybeans. Please refer to our monthly newsletter under “Fungicide Forecast” for details on application timing, rates and products available.

Delays in the East...

Delays in the east…

As usual, farmers are finishing up planting in the central part of Wisconsin while the Eastern half looks to get going. Heavy rains the past week have delayed planting yet another week on the heavy clay grounds. The alfalfa fields have been burned off and corn fields that are not under water seem to be worked up and ready to go. Although it is late in the year, this is a common trend on the shore of Lake Michigan. Colder soil and air temperatures delay any activity in the ground, typically two weeks longer than those west of highway 57. As farmers plant the high ground this week, dry weather looks promising for the next few days.
