Soybean rust - Zimbabwe: first report
in 2004
This is just to inform everyone that soybean rust [caused by
_Phakopsora pachyrhizi_] has been confirmed today (23 Jan 2004)
within the Lions' Den area of Zimbabwe in several commercial
plantings. This is the first confirmation of the disease for
this season. There is also an unconfirmed report in the Kwekwe
area (I am awaiting samples).
Although the level of severity at Lions' Den is very low,
initial infection is likely to have taken place at least 15 days
ago under very dry, hot conditions. The disease, however, will
most likely spread very rapidly on any unsprayed crops under the
very wet, humid conditions that are now prevailing.
Farmers who have not already started spraying are urged to
follow fungicide control recommendations as soon as possible to
avoid yield loss.
