Maintaining Healthy Roots

Not all risks to yield are easy to spot – some exist below the surface. Root health is essential to overall crop health. Without it, plants are more susceptible to stress factors, such as cold spells, drought and disease.

Nematodes, though small, are one of the major challenges to the root health of California and Arizona nut, grape, citrus, vegetable and berry crops. These tiny roundworms feed on plants’ roots, limiting their ability to take in vital nutrients and drastically reducing yield and vigor.

To stop nematodes, growers must stay vigilant. Monitoring and cultural practices – paired with crop protection products – can protect trees and vines, ensuring healthy crops and strong productivity.
