Distribution and Integrated Management of Root Rot of Pea in Malakand Division

Jahangir Khan, Mumtaz Khan and Muhammad Amin

Abstract:
Aphanomyces euteiches, Fusarium oxysporium f.sp. pisi, F. solani f.sp. pisi ans Rhizoctonia solani were isolated from 135 infected root specimens collected from eight commerical pea fields at Malakand Division, Pakistan. However, A. euteiches was isolated most frequenty, followed by F. oxysporium f.sp pisi with frequency of 45.92 and 33.33 percent, respectively. For the first time, A. euteiches was recorded on pea from Pakistan as an important component of the root complex. All the isolated fungi were tested for pathogenicity on pea seedings of the variety "climax" and found virulent. The fungicides, benlate, ridomil and captan significantly reduced the incidence and severity of pea root when applied at the time of first symptoms appearance to the root zone, followed by a repeat treatment 15 days latter. The effectiveness of these fungicides was increase when used in conjunction with other management practices for two consecutive years on the same field.
