Description: Comparisons between abnormal and normal sprout clumps of tanoak (Lithocarpus densiflorus [Hook. & Am.] Rehd.) in northern California indicated that sprouts in abnormal clumps had about five times the number of sprouts per dump, were three times as wide, and only one-fifth as tall. Stunted and chlorotic sprouts were examined for virus and disease organisms that might be used for biological control of this often weedy species. No pathogens or viruses that could account for the abnormal development were found in field or laboratory. but tests were not exhaustive. Decline could be from physiological events, unidentified pathogens or viruses, or lack of genetic exchange as a consequence of successive vegetative propagation.
Keywords: sprout development, disease, virus, tanoak, northern California
