Stress responses

The extreme temperatures that we have experienced over the last month or so means that stress on all crops has been high. Some iceberg are not ‘heading’ properly and continuing to produce just leaf. This impacts on percentage yield and can increase harvest costs.

Bolting is another physiological response to stress (the plant just wanting to reproduce) and we are seeing this in many lines, but especially iceberg, cos, and salanova’s.

With a cool down in weather, these issues should improve, but the more autumnal weather patterns will no doubt throw up other issues!
