The chemical compound chloropicrin was very first synthesized in 1848 by Scottish chemist John Stenhouse and first applied to agriculture in 1920, when it was applied to heal tomato “soil illness.” About the up coming 10 years, it was employed to restore pineapple productiveness in Hawaii and to address soil fungal troubles in California. Above time, it commenced to be extensively applied as a fungicide, herbicide, insecticide, and nematicide.
Chloropicrin was initially applied on potato in 1940 as a wireworm suppressant and then in 1965 as a verticillium suppressant. Farmers stopped utilizing it on potato for several years, but about the last 10 years, it has found a resurgence in popularity — and for superior purpose, according to Chad Hutchinson, director of analysis at TriEst Ag Group, Inc., in his webcast “Chloropicrin Soil Fumigation in Potato Creation Methods.”
Made use of as a preplant soil treatment measure, chloropicrin suppresses soilborne pathogenic fungi and some nematodes and insects. With a 50 %-everyday living of hrs to times, it is completely digested by soil organisms right before the crop is planted, earning it safe and sound and productive. Opposite to well known perception, chloropicrin does not sterilize soil and does not deplete the ozone layer, as the compound is destroyed by daylight. Furthermore, chloropicrin has never been located in groundwater, owing to its very low solubility.
According to Hutchinson, chloropicrin-taken care of soil has a much healthier root system, improved drinking water use, and additional effective fertilizer use. Implementing chloropicrin to soil also success in larger crop produce and overall health. Hutchinson also comments on the compound’s potential to suppress a lot of common pathogens, such as the pathogen that results in typical scab and species of Verticillium, Fusarium, and Phytophthora.
Hutchinson concludes that the use of chloropicrin not only will increase output performance and profit potential for potato farmers, but it can also increase soil health, “the basis of a good crop creation system.” His presentation “Chloropicrin Soil Fumigation in Potato Creation Programs” is entirely open entry and accessible on the net.
