If the price is right...use it.
Scotts has used pendimethalin for 20 years at least.
They probably own the only factory.
Be sure to use enough--do not skimp--no light coverage.
In fact, with any product, it is a good idea to walk extra slow in areas that are crabgrass-prone--or known to have a crabgrass problem.
Employees can seldom be trusted to do this. Owner-operated operations that have data on the crabgrass infestations from previous years, can up the rate to the maximum allowed.
Calibrate your spreader so that you can open up the spreader to two notches higher for "short-cut" areas, if the label allows.
