Figure 5. In planta performance of 1-aminoNBs.

Results of in planta testing in a greenhouse setting, a 250-ppm solution in acetone (~750 μM for these compounds) was sprayed on wheat heads 24 h before spraying heads with F. graminearum conidia (isolate Ph-1) with surfactant tween at anthesis in a susceptible spring wheat variety. A maximum of 600 μL was applied to each head, leading to an estimated maximum dose of 0.15 mg per head. Approximately 21 days after inoculation, wheat heads were rated for necrosis (sign of infection) by counting the number of affected spikelets per head. Three pots with at least 3 plants per pot were used in each experiment, and 2 runs were completed, with the mean of both runs presented here, and error bars representing the standard error of the mean.
