The pressure to produce flawlessly consistent playing conditions is stressful on biological organisms, i.e., plants and people. We seek any solution to enhance plant health when backed into a corner with weak turf, poor growing environments, stress from close mowing, etc. Sometimes these solutions help, other times they have unintended consequences.
All the rage this year about Bacterial Wilt/ Decline has me wondering about these unintended consequences when it comes to our obsession with plant health. You dont understand, a competent golf turf manager said to me about 10 years ago, I use these biostimulants because I grow grass on the edge.
Today we have all types of bio-stimulants some with good solid research to support use like seaweed and some amino acids, others not so much. Many are concoctions of carbon based compounds, with unproven amino acids, vitamins, and my favorite — Organic Photosynthesis Synergizer! We use these in the name of enhancing plant health but now there is growing suspicion that many of these plant health products might be enhancing the plant all the way to Bacterial Decline.
Here is my logic. The plant has many endophytic associations with bacteria, just like we do in our gut. We are applying cocktails of compounds most of which we barely understand whats in them. Next we put the plants under stress or on the edge if you will and the concoctions we are using are stimulating the bacteria INSIDE the plant and sometimes there are bacteria such as Acidovorax that can lead to decline.
Now some panic and run for the Mycoshield because a diagnostic technician said they have bacterial wilt. Now raise your hand if you think our society needs MORE anti-biotics introduced into the environment.
You think the current palette of plant health products is causing unintended consequences, stick around for the antibiotic resistant organisms we might create by spraying tetracycline every seven days!
