Isolation and Identification of Pathogenic Bacteria of Root Rot of Haloxylon Ammodendron and Determination of Toxicity Measurement
摘要
Abstract
Haloxylon ammodendron is one of the main tree species for windbreak and sand fixation in Wuwei desert area.In order to determine the pathogen species causing root rot of Haloxylon ammodendron,the samples of root rot of Haloxylon ammodendron were collected.The root tissue of Haloxylon ammodendron was isolated and purified by tissue separation method,and identified by morphological characteristics and molecular biological determination.The results showed that the strains isolated from the diseased samples belonged to Fusarium,which were Fusarium verticillioides,Fusarium proliferatum and Fusarium clavum.Among the four fungicides,30％hymexazol had the best inhibitory effect on Fusarium proliferatum and Fusarium clavatum,and its toxicity measurement EC50 was 0.423 7 mg·L-1 and 0.855 1 mg·L-1.Difenoconazole·trifloxystrobin 40％SC had the best inhibitory effect on Fusarium verticillioides,and its toxicity measurement EC50 was 0.612 8 mg·L-1.关键词
