Project Type: Trust Fund Cooperative Agreement

End Date: Apr 30, 2021
Determine the distribution and development of fungicide resistant isolates on table grape, in order to design case-specific rotational programs that reduce the presence of resistant isolates, and guarantee a good control of the pathogen over time.
We propose to collect powdery mildew samples from three out of the six fungicide rotation programs tested by our collaborator. Samples will be returned to the lab for chelax extractions. DNA will be tested for the G13A mutation that confers resistance to QoI fungicides in Eryisphe necator. Remaining DNA will be used for next generation exome sequencing.
