Results and discussion
- Details on results:
- Tributyl phosphate (TBP) is used as a constituent of cotton defoliants, producing leaf scorching, and is associated with an increase in the rate of leaf drying. TBP increases the drying rate of lucerne, resulting in excessive leaf loss. TBP applied by spraying as an emulsion (at a rate equivalent to 0.25% of freshly harvested leaf/weight) doubled the drying rate of ryegrass leaves. Leaf respiration stopped and did not resume in the subsequent 4 days.
TBP has been shown to damage the leaf surface and help herbicides penetrate bean leaves. There is no information on the effects of TBP on non-target plants, even at concentrations designed to produce desiccation of crop plants. - Results with reference substance (positive control):
- No information available
- Reported statistics and error estimates:
