Dale Wehmeyer and his wife Lisa started Wehmeyer Seed in 1995 after 11 years of being the Manager of Missouri Foundation Seed for the University of Missouri at Columbia. They moved back to open Wehmeyer Seed Company in her hometown of Mascoutah, Illinois, so the transition was good for their family. We sat down with Dale to hear more about his company and how they work with their customers.


Tell usWehmeyer Seed District Sales Managers about the beginning of AgVenture Wehmeyer Seed.

We are an independent, family-owned seed company. The goal was to replicate Foundation Seed quality and purity standards for the broader, commercial seed production business. We began small, as do most companies, with a few hundred acres of seed production that we were raising and selling.

We partnered with AgVenture seed in 2007 because AgVenture does business differently than other seed companies. Their four core values are the reason why we know AgVenture can bring our customers more bushels and more profit:

  • Localized product selection for the best genetic adaptation
  • Enhanced seed quality and treatments
  • Local ownership, knowledge, and support
  • Their proprietary Maximum Profit System™

It is a great partnership with AgVenture! Today we raise over 17,000 acres of soybean seed and wheat seed annually at our seed plant, in addition to other locations for unique variety adaptation.

Besides AgVenture seed, what other goods/services do you offer your customers?

NEW for 2022, we are offering precision drone fungicide applications. These turn-key application services are for corn, soybeans, and wheat. We all know fungicides play an important part in high-yielding crops and our Maximum Profit System™.  Applying fungicides with a drone offers a greater ROI due to uniform flight height of 10’ above canopy, constant flight speed, and maximum coverage.

The Maximum Profit System™ is A PROVEN SYSTEM for using AgVenture’s products with year-round agronomic leadership to help you PRODUCE MORE bushels.

What sets you apart from the competition?

Small changes can make a big difference.  Here’s how we are different:  First, we are independent and family-owned.  If you want to talk to ownership, you are welcome to stop by and visit us.  Second, we regionalize seed products better than anyone.  We identify and produce the best seed for our local environments which increases yields.  Third, we back our elite genetics with enhanced seed quality and treatments.  Growers get the very best.  For growers wanting to push yields even higher, we bring them our proven Maximum Profit System™, designed to raise APH by 20%.

“I use AgVenture because of their excellent products, service, and agronomic support. When we need something they respond quickly. I can’t think of any reason why we wouldn’t use AgVenture. AgVenture stressed the importance of new technology on our farm and is helping us maximize our yield maps, soil grid maps, and fertilizer application data. I do business with AgVenture because they are very trustworthy and service oriented.”
