Screening of Low Toxicity Chemical Fungicides for Control of Ginseng Black Spot Disease Caused by Alternaria panax
摘要
Abstract
Objective: To screen low mammalian-toxic pesticides in the library, and provide reference for the control of the leaf and stem blight disease caused by Alternaria panax Whetz in Panax ginseng. Methods: Plate-culturing method combined with the inhibition rate and toxicities were used to examine the efficiency of fungicides tested. Results: New Tono, golden mycophenolate and carbendazol existed the highest toxicity against Alternaria panax, and their EC50 values were199. 5 μg·m L-1, 181. 97 μg·m L-1and 96. 83 μg·m L-1, respectively. Then were Mancozeb, Amistar, and score with the EC50 values of 2041. 7 μg·m L-1, 3162. 3 μg·m L-1and 1258. 9 μg·m L-1, respectively. The EC50 values of the other fungicides were higher. Conclusion: New Tono showed good disease controlling potential against Alternaria panax, which can be used for the control of ginseng leaf and stem blight disease in the field after ensure the disease controlling efficacy and pesticide residue.关键词
