I must have been 13 years old when I started working as a helper gardener with the Franciscan monastery in Corrandulla, and no this was not to be my path! It was purely a means to an end for a young lad and to be fair I had an interest in working outdoors and with plants.
The monastery had glass houses and a walled garden, it was amazing and unheard of back then in the mid 80’s. There were tomato plants in those glass houses. I cannot tell you how unbelievable it was to see tomatoes growing in Galway back then. One job I remember in particular was using a knapsack sprayer for the first time. This is a sprayer that you put on your back. The head Gardener filled up the sprayer and I was given the job of spraying the tomatoes, I was told the spray was for the plants and that was it, and off I went to do my job.
The tomatoes were doing really well, so I sprayed the plants thinking I was doing some good. The day finished and I remember it was a Friday, and I went home. On my return to work on Monday I was greeted with a less than happy monk, the plants were all dying, I guess he added the wrong chemical to the mix, it was quite probable it was Roundup. Since Roundup’s introduction in 1974, weeds have out paced the ability of chemicals to control their presence. Superweeds are now well documented such as Palmer amaranth. The chemical company’s response has been to increase the application rate of the said chemical or/and merge two herbicides such as Glyphosate and Dicamba, the second of which is now banned again.
These increased toxic cocktails are not a step in the right direction.
The entomologist Robert van den Bosch coined the term “pesticide treadmill,” a concept referring to the slow escalation in the potency of the chemicals needed to control pests and maintain crop yield. The challenge of course though is in a world now reliant more and more on GMO seeds and heavy doses of one single herbicide, how do farmers in this system produce food when it fails as it is now.
There are different possibilities, but there is little doubt that the years of cheap commodity crops being raised to feed animals may be coming to an end.
The number one reason that organic food is more expensive than conventional food is the labour required to manage weeds. Spraying a field with a chemical is easy and cheap. Having said all of that the potential benefits of moving away from chemical agriculture towards a more holistic approach to food, can be financially viable. The costs associated with less sickness, increased biodiversity, less pollution, clean water, clean soil and healthier food; these hidden costs of the impact of our current approach to agriculture could then be redistributed fairly to farmers to protect our amazing planet. Like the tomatoes in the green house, it was as I know today completely possible to grow these phenomenal plants without any synthetic chemicals whatsoever.
As always thanks for your support.
