In laboratory experiments, neem oil in concentrations of 1.0-1.25 percent was found to cause greater than 80 percent combined larval and pupal mortality of L. trifolii on cucumber leaves. Concentrations of less than 1 percent were less effective, while 1.5 percent did not produce a significant further increase in mortality.
