Citrus black spot (CBS) has been responsible for substantial damage in citrus, in different countries. In Brazil, the disease occurs in several municipalities in the State of Sao Paulo, in an area that is highly representative of the state's citriculture. Black spot control basically relies on the use of protective or systemic fungicides, applied at 28-day intervals. The objective of this work was to evaluate the effects of biocontrol agents (Bacillus subtilis and Trichoderma sp.) and other alternative products (cow milk and biofertilizer) to control CBS in organic and conventional systems.
