Chemical techniques are used to eradicate Phytophthora from production equipment, water, and soil. Other chemicals are used to protect plant tissues from infection or to inhibit further growth of the organism inside plant tissues.
Integrating several techniques should help prevent losses due to Phytophthora diseases.
