After three injections of 1 ml of 0.01% DHT solutions under the cortex of the stems of 100% artificially or naturally with prunus necrotic ringspot virus infected sweet and sour cherry plants of 4 varieties axillary buds were grafted onto the indicator plant Shirofugen. 99% of these buds proved virus free. Contrary to this, only 28 to 32% of the buds from solvent injected control plants proved free of viruses. About 65% of the fruit‐trees grown up from buds of DHT treated plants were still virus free, when the test procedures were performed again two years later. Treatments of the sour cherry variety Podbelskaja with DHT were by far less effective.
