An issue being reported on some farms this week is “leaf drop”. This is where the midrib of the leaf breaks about 2.5 cm (1 in) from the stalk. Leaf drop is often seen in the lower stalk positions, i.e. sands, seconds or thirds. Some varieties are more prone to this condition than others. In addition, stage of growth and environmental conditions are contributing factors. Leaf drop tends to be greatest shortly after a rain or irrigation when the plant is close to the topping stage and conditions are hot and humid. High winds during the stage when the plant is vulnerable to leaf drop can increase leaf breakage.
