Why are Plant Pro-Tec UNITS long lasting?
The garlic odor from an activated Plant Pro-Tec UNIT is evident for 6 to 8 months, a whole growing season! The garlic odor lasts a long time for two reasons: 1) The garlic odor is from concentrated garlic oil- one ounce of the garlic oil is equivalent to 200 pounds of fresh garlic! 2) We have created a slow release system. Sulfur compounds give the garlic its repelling odor, and if exposed to air, sulfur compounds oxidize. As oxidation occurs, the garlic odor dissipates. It is the same as watching an exposed apple core turn red with rust as it oxidizes. We prevent oxidation of the sulfur compounds by sealing out air with a plastic cone ( See cross section diagram, at left). The cone, however, allows the garlic odor to slowly permeate through. Without the cone the garlic odor would be evident for 1 to 2 months. With the cone the garlic odor is evident for 6 to 8 months, a whole season! Another reason the repelling garlic odor is long lasting is that the garlic formulation is not affecte
