Carter, W. 1945b The influence of plant nutrition on susceptibility of pineapple plants to mealybug wilt.. Phytopathology 35(5): 316-323.
Notes: For the past several years experiments have been conducted on the relationship between plant nutrition and susceptibility to mealybug wilt of pineapple plants. The primary object of these tests was to determine whether or not susceptibility could be reduced under field conditions by modifications of the prevailing fertilizer practice. Initially, tests were with plants grown at varying levels of nitrogen, potash, calcium and iron fertilizer, each element being considered in a separate experiment. In later experiments, combinations of nitrogen, potash, calcium and iron fertilizer, each element being considered in a separate experiment. In later experiments, combinations of nitrogen, potash, iron and partial sterilization of the soil were studied. All experiments were in the field on a scale sufficiently large to permit statistical analysis of the data and at the same time to afford an unusual opportunity for observations on the etiology of the disease. The latter are recorded in a concurrent paper.
