Basal Rot of Prickly Pear


Basal rot of prickly pear and other cactus species usually develops near the soil line. Symptoms may include a discoloration of tissue, (yellowing or browning), a water-soaked rot, and eventual collapse of the entire plant.

Cockroaches and "The Bomb"


You've probably heard the story about cockroaches surviving a nuclear war: we die but they live! This is supposed to make you feel better when you have trouble getting rid of these critters.

So, the real truth: radiologists have found that humans can safely withstand a one-time exposure of 5 rems (A "rem" is the dosage of radiation that will cause a specific, measured amount of injury to human tissue). A lethal dose is 800 rems or more (people are exposed to about 16 rems during their lifetime).

Deicing Materials for Slick Sidewalks and Roads


Having just returned from a Thanksgiving holiday where ice has been a major problem already this winter, a discussion on deicing materials seems appropriate. Ice on sidewalks and roadways makes for a hazardous combination to people and property. Removal of compacted snow and ice with shovels or snow blowers isn't always easy or effective. The use of a chemical deicer may be needed to facilitate removal.
