Thrips threshold validation – commercial-scale experiments 2015–16 locations
Aims

The experiments are part of a project to validate whether the Australian Cotton Industry thrips threshold applies in southern NSW cotton production areas.

Key messages

• Thrips pressure was lower in the earlier planted Whitton site.
• Thrips pressure reached the industry control threshold of 10 thrips/plant on 3 November while plants were still at the cotyledon to 1-leaf stage at the Darlington Point site, and only in some plots at Whitton on 9 November and most plots on 23 November when plants were at the 6–8 leaf stage.
• Onion thrips were the dominant thrips species observed during monitoring.
• Western flower thrips constituted less than 5% of thrips monitored.
• There was no yield difference between sprayed and unsprayed plots.
