We have noticed slight leaf spot disease on the Albion day-neutral strawberry leaves within the last two months. However, the disease pressure has increased in the last two weeks in the non-low tunnel plot. As you can see below, the leaf spot is much more prevalent on the non low-tunnel plant leaves than in the low tunnel. Notice the bulls eye appearance with a gray center on the leaves.
Leaf spot disease is a type of fungal disease; the fungal spores are transmitted by water splashing up onto the strawberry leaf surface. In our growing area, we have had higher than average rainfall in 2015.
