Compatibility of entomopathogenic nematodes (Nematoda: Rhabditida) with insecticides used in the tomato crop

Abstract

Entomopathogenic nematodes (EPNs) are agents that can be used for the biological control of pests associated with insecticides in a tank mix. Compatibility studies need to be conducted to analyze which products are compatible with nematodes. The aim of this work was to evaluate the compatibility between EPNs and the insecticides that are most used on the tomato crop, and to correlate the toxicological classification of the chemical products with two species of EPNs that have the potential to control tomato leaf miner, Tuta absoluta. Among the products tested, Certero® (triflumuron), Decis® (deltamethrin), Previcur® (dimethylamino-propyl), Ampligo® (lambda-cyhalothrin + chlorantranilprole), Premio® (clorantranilprole), Engeo Pleno® (thiamethoxam + lambda-cyhalothrin) were compatible (IOBC class 1) with both nematode species.
