Soil drench method of fungicides application was the higher efficient method in elimination of percentage of disease incidence and disease severity followed by foliar spray application, relatively.

Banaty transplant was the most susceptible cultivar to the all tested B.

theobromae isolates, whereas cultivar Gizy Ahmr was the lowest susceptible with the same isolates, information about cultivar reaction of guava transplants against B.

theobromae is still scanty.
