| Description | Drechslera sorokiniana was detected in certified New Zealand barley seed from the 1976–77 harvest. In the North Island seed samples tested, 17.5% of lines were infected and the mean percentage of seeds infected per line was 0.6%. This was lower than results previously reported for seed from the 1974–75 and 1975–76 harvests (45% and 34% of lines infected respectively). This reduction in seed-borne inoculum is linked with a change in barley seed treatment, from captan to systemic-based fungicides. In the South Island, where the use of captan was continued, 26% of seed lines from Marlborough-Nelson were infected, a level similar to the previous two seasons, and the fungus was recorded in seed from Canterbury for the first time. Conidia of D. sorokiniana were detected in low numbers in soils from Manawatu-Rangitikei, the range being 0–164 conidia/g soil, with a mean of 12/g soil. The mean percentage viability of these conidia was 48%. This work demonstrated that infection of subcrown internodes of barley plants from soil-borne conidia occurred in the field. |
