Dear Editor:


The World Health Organization has warned that glyphosate, a key ingredient in Roundup, is “probably carcinogenic to humans,” and California is adding the herbicide to its list of chemicals that can cause cancer.

According to the National Pesticide Information Center, the surfactants in Roundup may also cause toxic reactions in dogs and other animals who are exposed to it, including weight loss, lethargy, excessive drooling, vomiting, and diarrhea.

We don’t have to put the health of our animal companions at risk. Improved soil health, plant nutrition, and irrigation help combat weeds. Applications of vinegar and essential oils such as clove, orange, and lemon have also shown promising results in controlling crabgrass, ground ivy, and other weeds.
