Answer:
If there is low genetic diversity, she needs to introduce something into the system to increase the variation. I would suggest breeding the orange trees with other new orange trees to change the allele frequencies, which is called gene flow.
Likely the fungi are attacking them somewhere that they have decreased resistance, and if more alleles were introduced, there would probably be evolution towards a genotype that promotes defense against these fungi.
