摘要

A control composition which comprises Z,Z/Z,E-7,11- hexadecadienyl acetate and Z,Z/Z,E-7,11-hexadecadienyl alcohol is released into a cotton field in a weight ratio of Z,Z/Z,E-7,11- hexadecadienyl acetate to Z,Z/Z,E- 7,11-hexadecadienyl alcohol ranging from 99.2:0.8 to 90:10. The control composition is preferably released in the weight ratio defined above and in a rate ranging from 4 to 80 mg/hr/hectare of field.
