Other claims from this paper (9)
- Intervention effect Picloram and DEF mixtures caused more severe effects at nine months than either alone in poplar and privet.
- Observation Earlier DEF synergy with triethylamine 2,4,5-T on privet diminished or disappeared.
- Intervention effect DEF mixed with 2,4,5-T iso-octyl ester had antagonistic short and longer term phytotoxic effects.
- Intervention effect DEF synergized with salt or amine formulations of picloram, 2,4,5-T or mecoprop in guava.
- Intervention effect DEF antagonized ester formulations of the herbicides in guava.
- Intervention effect 2-Butyne-1,4-diol had no effect on picloram ester phytotoxicity.
- Intervention effect Xylene did not appreciably increase picloram effects when a wetting agent was present.
- Intervention effect Triton B 1956 did not appreciably increase picloram effects when a wetting agent was present.
- Intervention effect DEF and picloram did not interact when introduced into guava vascular tissue.
