    Effect of two commonly used nitrogenous fertilizers on infective Ascaris lumbricoides Ova
    (Sri Lanka Medical Association. Colombo, 1976) Edirisinghe, J.S.; Ihalamulla, R.L.
    The effect of urea and ammonium sulphate on effective Ascaris ova was studied. It was shown that these two compounds have no ovicidal effect on infective Ascaris ova in the concentrations used. Decortication of the Uva was observed in the first two concentrations of both test solutions. The motility and the hatchability of the contained larvae were also lowered in the higher concentrations of the test solutions.
