Research Summary Abstract
TDA-01 is a new active ingredient for foliar plant pathogens such as bacteria. The IR-4 Project has screened 3 different formulations, completing 28 crop safety trials on 9 environmental horticulture plant species or genera from 2017 through 2021. The first two formulations caused moderate to severe injury, so a third formulation was developed. For TDA-NC-1, only one crop (Begonia sp.) exhibited no injury after three consecutive foliar sprays applied at 2 week intervals. The eight other crops have been screened in less than three trials, so no conclusions can be drawn yet.
