Hence it is exceedingly dangerous in re- gions where the wilt prevails to use any stable manure on the field where melons are to be planted. Varieties resist- ant to this disease have been devel- oped by the United States Department of Agriculture by crossing the citron, which possesses high resistance, with the watermelon, and then by selection attaining the desired edibility. Wilt, bacillose. See cantaloupe. Wilt, micosphaerellose. See cantaloupe. Fig. 137. — Portion of watermelon showing effect of anthracnose. After Sheldon.
