Chloropicrin Is a Beneficial Chemical for Potato Farmers

The chloropicrin a chemical compound was first synthesized in 1848 by Scottish chemist John Stenhouse and first utilized in agriculture in 1920 when it was used to treatment tomato “soil illness.” Over the subsequent decade, it was used to revive pineapple productiveness in Hawaii and to handle soil fungal issues in California. Over time, it started to be extensively used as a fungicide, herbicide, insecticide, and nematicide.

Chloropicrin was first used on potato in 1940 as a wireworm suppressant after which in 1965 as a verticillium suppressant. Farmers stopped utilizing it on the potato for a few years, however over the past decade, it has seen a resurgence in reputation — and for good motive, based on Chad Hutchinson, director of analysis at TriEst Ag Group, Inc., in his webcast “Chloropicrin Soil Fumigation in Potato Production Systems.”

Used as a pre-plant soil therapy measure, chloropicrin suppresses soil borne pathogenic fungi and a few nematodes and bugs. With a half-lifetime of hours to days, it’s utterly digested by soil organisms earlier than the crop is planted, making it protected and efficient. Opposite to well-liked perception, chloropicrin doesn’t sterilize soil and doesn’t deplete the ozone layer, because the compound is destroyed by daylight. Moreover, chloropicrin has by no means been present in groundwater, on account of its low solubility.

Based on Hutchinson, chloropicrin-handled soil has a more healthy root system, improved water use, and other efficient fertilizer use. Making use of chloropicrin to soil additionally ends in better crop yield and well being. Hutchinson furthermore comments on the compound’s capacity to suppress many common pathogens, together with the pathogen that causes common scab and species of Verticillium, Fusarium, and Phytophthora.

Hutchinson concludes that the usage of chloropicrin not solely will increase manufacturing effectivity and revenue potential for potato farmers; however, it may additionally enhance soil well being, “the muse of an optimistic crop manufacturing system.” His presentation “Chloropicrin Soil Fumigation in Potato Manufacturing Techniques” is open entry and accessible online.
