Don’t let FOV Race 4 limit your Pima potential

With the PhytoGen Breeding Trait™ for built-in tolerance to FOV Race 4, California producers can maximize yield and quality.

Environmental and agronomic conditions allow California cotton producers to grow Pima varieties with some of the best fiber quality in the world. A moderate climate is conducive to consistent yield and quality, but western cotton producers face unique challenges.

One of those is Fusarium (FOV) Race 4, a soilborne fungus that infects cotton plants and reduces yield. FOV Race 4 enters the roots and spreads through the vascular system. Symptoms include wilted, yellowed or dead leaves. Heavy infestations of FOV Race 4 can lead to large areas of fields with missing plants.

FOV Race 4 is particularly difficult to manage because there is no crop protection treatment once it’s in a field. For that reason, the University of California Cooperative Extension recommends planting varieties with high levels of tolerance to FOV Race 4 in fields with known infestations.1

That’s why PhytoGen provides FOV Race 4 tolerance in all its Pima varieties: PhytoGen® brand PHY 841 RF, PHY 881 RF and PHY 888 RF. With the PhytoGen Breeding Trait for built-in tolerance to FOV Race 4, California producers can maximize yield and quality.
