ImmunoStrip® for Phytophthora (Phyt)

The Phytophthora (Phyt) ImmunoStrip® is used to detect the presence of Phytophthora species in many crops including Oak, Potato, and Strawberry. ImmunoStrips® are the perfect screening tool for use in the field, greenhouse, and the lab.

This test is recommended for use as a preliminary screening tool in survey programs for Phytophthora species such as P. ramorum (Sudden Oak Death) and P. kernoviae. The test is also suitable for detection of Phytophthora species that affect other important crops such as P. fragariae in strawberry or P. infestans in potato.

The Phyt ImmunoStrip® detects Phytophthora to the genus level and cannot differentiate species. For a full list of species that have experimentally detected click here.
