A polymer composition comprises a minor amount of a pro-degradant selected from essentially carbocyclic β-diketones and metal complexes thereof, e.g. 2,2′-methylene(1,3-cyclohexanedione) or its Mn(II) or Zn complex. A film of the composition may be used for the protection of seeds or seedlings at an agricultural or horticultural locus.
