SACRAMENTO -- Starting Monday, selected areas of the Delta -- including the waters around Brentwood and Discovery Bay -- will be treated for the invasive plant water hyacinth.

Treatment of the plant will continue in selected parts of the Delta through the end of November, according to a state Department of Boating and Waterways news release.

Managing the plant will be difficult this year, especially given last year's late treatment start, lack of heavy frost, continued warm temperatures and the characteristics of the plant, said Sylvia Ortega Hunter, the agency's acting director.

"Since the 2013 control program has been adjusted to accommodate these issues, (the department) hopes to realize better results this year," she said.

Some Delta sites, including waters around Pittsburg, Antioch, Oakley and Bethel Island, will not be treated until June 1 to protect listed salmon species and Delta smelt.

Sites will be treated using two herbicides: glyphosate or 2,4-D. Treatments can take at least two weeks or longer to start appearing, showing with gradual wilting and yellowing of the plant, advancing to browning of vegetation and eventual decay.
