Conteúdo: | 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 105-837 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. Although the severity of the leaf symptoms increased noticeably according to treatment, especially on mature leaves, the D [the most recently fully matured] leaf mass shortly after flower induction was not significantly affected. Leaf symptoms developed 6 wk after initial treatment and increased in severity with continued biuret applications.
