Abstract
Results of transmission trials conducted with coconut wilt 'virus' on seedlings of coconut grown in an insect proof screen house are reported. Primary symptoms of flaccidity. paling and slight stunting of younger leaves were observed on 5 of the 6 seedlings inoculated by rubbing, 2 1/2 to 3 1/2 years after inoculations were started. One of the 6 seedlings inoculated by means of infective S. typicus got diseased and showed paling and stunting of leaves. One of the 2 seedlings inoculated through soil also developed the disease. Soil at the base of some of the diseased seedlings became infective as evidenced by the cowpea test.
