NUFARM has shocked the market with a sharper-than-expected halving of full-year earnings guidance due to pricing and weather conditions.

The crop protection maker's sales suffered in its crucial final quarter, The Australian reports.

Less than a month after Elders' similar downgrade, Nufarm yesterday said it now expected net operating profit of between $55 million and $65m, excluding non-operating items, for the year to July 31, down from $110m to $130m.

Analysts had been predicting a result of about $95m after Nufarm's most recent guidance in March, when it unveiled a first-half loss of $40m.

Nufarm managing director Doug Rathbone, who in March sold 3 million shares in the group as part of a gradual sell-down, said the result was extremely disappointing and unsatisfactory.
