To effectuate W912HZ-22-2-0026 P00004, the Research and Development Cooperative  Agreement identified by FAIN W912HZ-22-2-0026 is hereby reissued as W912HZ-26-2-A029. This newly numbered cooperative agreement is necessary for the agency to adapt to the Army’s new contract writing system and ensures that all future activities related to this cooperative agreement can proceed without issue. 

A new Cooperative Agreement (CA), W912HZ-26-2-A029, is being awarded to carry forward the option(s) that have not been exercised prior to the migration of Cooperative Agreement W912HZ-22-2-0026 into the new Acquisition Contract Writing System (ACWS). 

This administratively newly numbered cooperative agreement, W912HZ-26-2-A029, will abide by the same terms and conditions agreed upon at award of CA W912HZ-22-2-0026, as modified through P00004. 

Under W912HZ-22-2-0026, options 1, 2 and 3 were exercised prior to migration. W912HZ-26-2-A029 will be awarded at $30,000.00 (option 4/year 5). Option 4 and any unforeseen modifications related to this option and any modifications for any additional funds as applicable will be issued under the new cooperative agreement. W912HZ-26-2-A029 does not replace W912HZ-22-2-0026 but will be utilized for continuation of research and obligation of funds.

Abstract: 

Flowering rush (Butomus umbellatus L.; FR) is an invasive aquatic weed in Oregon native to Eurasia that can have negative impacts on irrigation, recreation, and ecological systems. Dense stands can outcompete native riparian and aquatic plants, interfere with boating and fishing, and impede irrigation flows. Control of FR necessitates EDRR (early detection rapid response) action.
