Abstract
Laboratory studies using Hard Red Winter wheat treated at 1.85 and 4.00 p.p.m. with ronnel, sampled as Korlan 24 E, produced mortalities of 50% and 95%, respectively, immediately following a 14-day exposure. A dosage of 1.00 p.p.m. produced a mortality of only 7% but reduced reproduction approximately 94%. Odor, feel or appearance of the wheat was unaffected at. 5.0 p.p.m.; however, 10.0 and 25.0 p.p.m. produced odors.Keywords
