Effect of fungicides on shot hole disease of almonds
California Agriculture 43(3):21-23.
Several registered fungicides evaluated over a 7-year period in the southern San Joaquin Valley controlled the disease on fruit. Captan, captatol, and ziram preceded by dormant copper provided the most consistent control. Fungicides protected against yield losses in a heavy-disease year but had no effect on yields when the disease was not prevalent.
