NEW YORK ( TheStreet) -- DuPont ( DD - Get Report) lowered its 2011 full-year earnings guidance because of slower-than-anticipated growth in the fourth quarter.

DuPont reduced profit guidance to $3.87 to $3.95 a share, down from estimates it made in July of $3.90 to $4.05 a share. The Wilmington-based company raised earnings estimates in April and July this year.

"We are seeing slower growth in certain segments during the fourth quarter, driven by global economic uncertainty," said DuPont CEO Ellen Kullman, in a statement Friday. "This uncertainty is contributing to ongoing conservative cash management in some supply chains."

Jefferies analyst Laurence Alexander lowered his 2011 earnings guidance on DuPont by 10 cents to $3.90 a share, and his 2012 estimates by 20 cents to $4.05 a share based on DuPont's latest guidance. Alexander anticipated DuPont will say it expects 2012 full-year earnings of between $3.95 and $4.15 a share.

"DuPont will likely echo 3M's ( MMM - Get Report) (MMM, $80.46, Buy) recent caution on the outlook for electronics in 1H12, as well as the broader caution about the pace of economic acceleration early in 2012 given the recent ratcheting down of leading indicators for growth in Europe and Asia," Alexander wrote.

Wells Fargo analyst Frank Mitsch called the implied fourth-quarter guidance of between 30 cents and 37 cents a share "rather wide at this late stage in the quarter" in a report Friday.

"Continued weakness in housing and construction markets as well as destocking in some industrial markets is weighing on Safety & Protection," Mitsch wrote. "Other businesses are performing as expected, including Performance Coatings (helped by still healthy auto) and Performance Chemicals (although Q4 is seasonally weak for TiO2 regardless). The Ag business will likely be supported by strength in Latin America."

Mitsch added that Monsanto ( MON) also recently cited anticipated growth in the Latin American agricultural business.

DuPont holds an investor day next Monday and Tuesday.

Dupont shares fell 4.7% to $44.33 in trading Friday.
