The use of pyrethroid insecticides on Helicoverpa armigera susceptible crops has been restricted to only 6 weeks each summer since 1983, when resistance to pyrethroids was diagnosed.

Summary of Key Results 1 Most promising techniques for use by advisory staff in the field are penetrometers and root morphological characteristics. 2 Soil smearing may not have significant effects on plant growth.

The number of methods of marketing open to Australian cotton growers has increased in recent years, providing growers with an opportunity to better manage financial risk.
