Late Blight Prevention Costs

Late blight prevention can cost a lot and the profit margins on a potato crop can be small, so cost containment can be important. Below is s summary of two fungicide program options - Intense with frequent expensive fungicides and Moderate on and early variety, Norkotah, and a late variety, Nugget. This is only an example and actual field conditions need to be adjusted for in any program. There is a large difference in cost between the moderate and intense programs costs, but only a $15 to $43 difference between Norkotah and Nugget costs. When one looks at the whole Norkotah and Nugget budget, they are virtually the same since Norkotahs usually have additional Ridomil (for leak control) and fertilizer costs. When one factors in the different marketing periods of Norkotahs and Nuggets, there still are strong reasons to continue growing Nuggets.
