Consan Triple action 20 is different than Physan 20. I have not used the Physan as a foliar spray but for general disinfecting of pots and other garden related cleaning tasks. I have read where Physan 20 was sprayed in growing beds prior to planting out tomato plants with no signs of disease appearing later on. Physan dissipates 24 hours after use. Check out this website. Just enter the product name and do a search and it will give you all the information concerning it and toxicity information for the active ingredients. Ami
