NemaShield is a biological control targeted to fight specific pests. The beneficial nematodes attack, disrupt, and kill harmful insect larvae in the potting media within 24-48 hours – preventing damage to plants and helping fight off disease by re-establishing a strong and vigorous root system. Plus, NemaShield is compatible with all other beneficial organisms, including RootShield® PLUS+ G and WP, making it an excellent tool in your integrated pest management program.
