Kaliumbicarbonat als möglicher Schwefelersatz im geschützten\ud Gemüsebau

By Martin Koller


The effect of the potassium bicarbonate product «Armicarb» was tested against powdery\ud mildew on tomato, cucumber melon, rosemary, sage and corn salad. The\ud disease reducing effect of potassium bicarbonate was comparable to sulphur for most\ud of the tested crops. With protective applications the efficacy was higher than 90 %.\ud However in melon were powdery mildew was present before the first spraying, the\ud efficacy was only 74 %. Compared to plant oils or extracts (such as fennel oil, tea tree\ud oil and lecithin) potassium bicarbonate has shown the same or better efficacy. In our\ud experiments we found no phytotoxicity caused by the potassium bicarbonate product\ud Armicarb®
