Accidental use of fire ant insecticide #198120

Asked July 10, 2014, 7:46 AM EDT

Is it safe to harvest yellow squash after accidentally applying Natures Guide Fire Ant Insecticide for treatment for squash bugs. Active ingredients: Pyrethrins 0.2 %, Technical Piperonyl Butoxideb1%, Silicon Dioxide ( from Diatomceous Earth 88%, Inert Ingredients 10.8%. Per label. When I discovered mistake immediately doused plants with water and deeply watered raised bed. Thanks.

I'm not specifically familiar with that pesticide label, but based on the list of ingredients you should have no problem eating squash that have grown on these plants after they have been decontaminated.  These ingredients are commonly found in other products labeled for vegetable gardens and are not systemic--that is they do not get absorbed into the plant.  In addition, pyrethrins have a very short life on plants, hours to days.
