If a microbe switches its preference to the non-toxic twin, then residues left on food can be more toxic then the lab test indicated. It is also possible for microbes to convert a single twin form into its missing twin. Fortunately, there are safe alternatives. We improve the world starting in our homes and in our own back yards. Here are some suggestions.
Spot treat only areas with problems and use natural non-toxic pesticide alternatives.
Use native vegetation as much a possible. In the United States, check with your state Agricultural Extension Service for information about native vegetation in your area. Consider allocating a portion of your yard to a natural area. Putting boarder plants or edging the grass around it will help the area blend in with your other landscaping. This is a great way to share your yard with birds and wildlife and make the beauty and peace of nature part of your life.
