A tree treatment capsule is disclosed as including a plastic container having a shank with an internal cavity for containing therein a chemical agent and a head integrally formed with the shank portion. A plastic plug is provided to sealingly close the cavity. The shank has a plurality of scorings which are formed in the exterior surface thereof and extend lengthwise of the shank The scorings allow the shank to be broken so that when an impact force is applied to the head to move the shank towards the plastic plug, the plastic plug expands and breaks the shank along the scorings into tongues to form slits between the tongues. The slits allow the chemical agent to pass from the cavity of the capsule through the slits and mix with sap of the tree.
