BioAct Prime DC is based on the beneficial fungus Paecilomyces lilacinus, also known as Purpureocilium lilacinum strain 251. It controls plant parasitic nematodes—including root-knot nematodes (Meloidogyne spp.), burrowing nematodes (Radopholus similis), cyst nematodes (Globodera spp.) and root lesion nematodes (Pratylenchus spp.)—by targeting eggs and larvae before they have an opportunity to attack roots.
Applications include tomatoes, cucumbers, asparagus, avocado, beans, broccoli, carrots, okra, onions, strawberries, citrus, nuts, grapevines, tobacco, young plantations, and tree nurseries.
When used in combination with Velum Prime, BioAct Prime DC enhances root health and leads to higher yields while lowering use of older, less environmentally friendly nematode-control products, according to Bayer.
