Fourteen plant extracts were evaluated in vitro against the fourth larval stage of Haemonchus contortus . The plants species used were Tagetes erecta, Argemone mexicana , and Castela tortuosa. The assays were run in 24‐well cell culture plates at room temperature with three replicates. After exposure, aliquots were taken from the corresponding wells and transferred to a microscope for observation. Evaluation criteria were based on the average of live and/or dead larvae. ANOVA test and Tukey test were used to determine significant differences among the treatments. After 96 h, the T. erecta acetonic extract produced 99.7% lethal activity, followed by C. tortuosa hexanic extract (85.8%) and T. erecta methanolic extract (58.3%) ( P < 0.0001).
