How quickly is the active ingredient eliminated from soil and the environment?
Carbon 14-labeled nicarbazin studies have shown that the half-life of nicarbazin in the soil is approximately 49 weeks in field soil and 18 weeks in greenhouse soil. Studies of labeled nicarbazin in field soil plots have shown that the nicarbazin incorporated into the upper 3 inches of soil does not leach through the soil beyond 6 inches in depth and slowly degrades over time. Since this product will be delivered under free-feeding conditions, how can you be sure you are not over- or under-dosing the geese with OvoControl? It is very difficult to administer exact doses of OvoControl under free-feeding conditions such as those that will exist using bait stations or broadcast feeding. Fortunately, OvoControl has been shown to have a wide margin of safety and efficacy and the bait is formulated such that the target dose is administered in just 1 ounce of bait.
