The two methods with the most promise, bark painting and trunk injection, have some technical problems associated with them that must be solved before either procedure can be fully exploited. The most important problem for chemicals applied by bark painting is that of transversing the suberized layer just below the outer bark. Trunk injection confronts two major problems in some trees, namely that of forcing solutions into small xylem vessels and sectorial-type distribution in wood with straight grain. Some results of trials with both techniques are discussed. ER -
