 Producing the highest quality cotton lint is paramount for cotton growers, PCAs, ginners and merchants. Honeydew produced by sweetpotato whitefly, Biotype B (Bemisia tabaci) and cotton aphid (Aphis gossypii) can settle on open bolls and create sticky cotton. The contamination of cotton lint with sugary honeydew creates major problems with the spinning mills

Sticky deposits on Draw Frame Creel will start to collect more and more loose cotton fiber resulting in machinery shutdown.

and can result in damage to the reputation of a cotton producing region.

UC IPM and California Cotton and Ginners Associations (CCGGA) recently hosted three workshops to remind the cotton community of the importance of managing these pests to prevent the development of sticky cotton.

The slides presented by IPM Advisor Pete Goodell and UC Davis Extension Entomologist Larry Godfrey are available through CCGGA link by clicking here.

In addition, a series of webinars on the subject has been produced by Cotton Incorporated and Plant Management Network. It is available through my website.

Detailed information on aphid and whitefly management can always be found at UC IPM Pest Management Guides.
