Protect Your Almonds Against Threats You Can’t See: Manage Nematodes with Velum® One

Why It Pays to Protect Against Nematodes

Nematodes are an invisible threat in the soil that can negatively impact soil health and harm your crops causing up to a 50% loss in annual yield in almonds.1 Worldwide, nematodes caused $157 billion in yield loss across crops in 2015.2 Healthy soil is the foundation for healthy food production. Healthy roots are fundamental for consistent high productivity and can improve yield and quality by 30–50%.

Your Solution for Post-planting Nematode Protection

Previously, growers had limited post-planting options to protect their almond trees from nematodes.

For tree nut growers, Bayer offers a solution with Velum® One, a nematicide with fungicidal activity that suppresses nematodes and helps provide higher yields. Velum One is a wide-spectrum nematicide that can be conveniently applied during the season through irrigation systems.
