The disease is caused by the several members of the genus Phytophthora, and includes (but is by no means limited to) the following species): P. cactorum, P….Read more about Recent Rains Driving Phuture Phytophthora Problems[Read More]

Each year, fruit is harvested from mother plants and daughter plants that are derived from established runners in the past year. Strawberries can also be grown using…Read more about Getting Ready to Plant Strawberries in a Plasticulture System — Planting Materials[Read More]

This is the same fungus that causes cankers on the tree, along with black rot of apple fruit (Fig. 1). Frogeye leaf spot…Read more about Frogeye leaf spot[Read More]
