These potent chemicals a major reason we wash our vegetables well before eating them-and an argument for buying organic. A pesticide is any product meant to repel, discourage, or kill pests-including insects but also rodents, fungi, weeds, bacteria, and microorganisms. Pesticides can take the form of bug spray, weed killer (sometimes called herbicide), and even bathroom sanitizer. Many chemical pesticides are toxic pollutants and can carry health risks if inhaled or ingested; biologically based pesticides can be safer choices, but aren't always. Other, more reliably safe alternatives include the use of companion plantings in the garden and physical rodent traps indoors. For more on pesticides, click here. |
