Biuret injury on pineapples

Glennie, J.D. and Parsons, R.B. (1981) Biuret injury on pineapples. Queensland Journal of Agricultural and Animal Sciences, 38 (1). pp. 43-46.



Biuret added to regular urea foliar sprays induced leaf yellowing and leaf tip dieback and at higher rates reduced plant crop yield by about 6%. The biuret impurity ranged from the equivalent of 0·5 to 0·4% biuret content in urea or 105 to 837 mg biuret per plant. Fruit yield was reduced at the 3 · 0 and 4 · 0% impurity levels but there was no significant difference between 0 · 5, 1·0 and 2 · 0% biuret impurity levels.
