Spray every seven days, blight warning

Met Eireann has this morning issued a high-level blight warning.

It said conditions favouring the spread of potato blight will occur at times in most parts of the country for the rest of this week and a status yellow warning has been issued.

The concept behind its yellow level weather alerts is to notify those who are at risk because of their location and/or activity, and to allow them to take preventative action.

It is implicit that yellow level weather alerts are for weather conditions that do not pose an immediate threat to the general population, but only to those exposed to risk by nature of their location and/or activity.

Teagasc potato advisor John Pettit has urged farmers to spray at seven day intervals.

Speaking to Agriland this morning he said: “With low blight pressure up to now growers have been stretching intervals to 10 days to reduce fungicide expenditure. Spraying with a longer 10 day interval will increase the risk of blight infection within crops substantially.”
