Good, better, best? The quest for better fumigating soil (McCain Foods Findings)

Nowadays disease resistance is a primary objective for all the main breeding programmes and will be more important in the future with the increasing quest for better fumigating soil.   

CARIBOU, Maine — The largest buyer of potatoes in Aroostook County, McCain Foods, has started trials examining soil fumigation with several of its growers. McCain Foods presented their findings at the Maine Potato Conference in Caribou in January 2017.

Going back in the 1920s the use of chloropicrin took off for a wide range of crops, with common uses today in strawberries and potatoes mostly in western states. Today, Fitzpatrick-Peabody says that the range of fungicides and insecticides farmers already apply to potatoes throughout the growing season “aren’t providing adequate control for soil-borne diseases”.

We all know that chloropicrin works better in heavier soils as it volatises very quickly, enabling it to move better through more compact soils. Soils can benefit from longer exposure periods as it readily degrades into carbon dioxide, nitrogenous compounds, and chloride. These are basic nutrients which not only foster healthy root and plant growth, but feed beneficial micro-organisms found in the soil.
