There is disclosed a unit dosage system for tree trunk implantation to control insect pests afflicting trees in which a plurality of vertically spaced apart holes (about 10-15 cm) preferably 10 holes, are drilled into the trunk and the holes are filled with about 0. 1 to 2. 0 gram unit dosage weights (as 100% active ingredient) of N-Acyl phosphoroamidothioates in a capsule as disclosed in Jensen U. S. Pat. No. 3,706,161. The active compounds are O-methyl or ethyl S-methyl or ethyl N-acetylphosphoroamidothioate which are technically pure (over 80%) and whose method of preparation is shown in Magee U. S. Pat. No. 3,716,600. A feature of the system is the provision of 10 capsules loaded with the active compound in a double or triple package within a package, each package being hermetically sealed to permit storage and shipment without giving off hazardous vapors. The inner package is a heat sealed metal foil lined package hermetically enclosing 10 capsules of the Jensen structure. Thus the user prepared by reading the instructions can quickly and efficiently make the necessary spaced vertical drillings, insert the capsule loaded with the highly effective agent, seal the opening with tree dressing and provide protection against citrus black fly, Jeffrey pine needleminer, Western spruce budworm, Zimmerman pine moth and the like.

Abstract:
A tree medication capsule is disclosed as including a vial having a medication sealed therein by means of an end cap; the vial, medication and end cap constitute a self-contained unit which is inserted into a predrilled hole in a tree. The vial is made of frangible material so that upon breaking, as by a mallet tap on the end cap, the medication is free to escape into the tree.
