GrubOUT® U2 Safety to animals


Cows eating Cropmark Seeds grass

Worldwide research has confirmed that lolines which are contained in GrubOUT® U2 are safe for ruminants such as sheep, cattle or deer. Lolines have not been known to cause grass staggers or heat stress.


They have no known negative effect on livestock performance.

GrubOUT® U2 is not yet recommended for horses.

Livestock performance

In animal safety trials trials conducted by Cropmark Seeds over three consecutive years, the live weight gain of lambs grazing GrubOUT® U2 grasses was equivalent to those grazing Ultra AR1.
 
Given the unparalleled yield performance of Ultra, and that the AR1 endophyte is a proven animal-safe endophyte, this is an excellent result.
