Predictive Weed Control With Greg Stewart of Geco Strategic Weed Management

Today’s episode features a new tool in the toolbox for farmers fighting weed pressure. As I’ve had conversations with farmers throughout the country, there is no doubt that the costs of weed control is a major pain point. This takes a lot of different forms, from the hand labor crews in California’s vegetable crops, to herbicide-resistant kochia in the middle of US and Canada to just the sheer cost of chemistry that’s impacting the bottom line of farmers everywhere, it’s certainly an area ripe for solutions. 

For the past few years, Dr. Greg Stewart has been working on a very interesting solution to use data to predict weed pressure. This is interesting because it’s addressing a major problem in weed control, but it’s also interesting because it embodies what where we all hope this “ag data revolution” is going: towards predicting problems before we experience them. This opens the door up for more proactive weed management solutions, in some cases before the crop is even planted. 

Greg is a listener to the show and he’s heard my requests over the years to not just feature founders of new technology, but also the farmers that are trying the solutions, so he offered to connect me to Rob Stone. Rob was nice enough to join me for a short interview while in the cab of a tractor, so you’ll get his perspective as well. Rob is a customer of Geco and not compensated by them in any way. He was invited on to openly share his experiences. 

Let’s dive into things here starting with an introduction to Greg. I’ll introduce rob when we cut to him mid-episode.
