Spore traps alert growers to late blight pressure.

Determining late blight presence and the resulting pressure on potato crops is an ongoing challenge. Usually, potato growers start a preventive fungicide program with broad spectrum fungicides before row closure, which ensures stems and leaves at the base of plants are protected from both early and late blight. If late blight is identified in the field, growers switch to fungicides that specifically target it for enhanced crop protection.

But what if it could be determined in advance if late blight will be a problem? Time and money could be saved.
