These projects utilize many different plants and fish although in recent times there seems to be a leader emerging from the pack of contenders. This fish is the tilapia.

The cleanest crop from a producer’s standpoint is actually spinach, with only 0.4 pounds of pesticide used per acre in California. Spinach is fifth on the Dirty Dozen list. Conversely, the crops with most intensive pesticide use are sweet potatoes and mushrooms, with 110.3 pounds per acre and 106.1 pounds per acre, respectively. The average pesticide use intensity for the lists is quite similar: 26.2 pounds per acre for the Clean 15 and 29.8 pounds per acre for the Dirty Dozen.
