The ability of isolates of Bacillus subtilis and Trichoderma spp. to control citrus black spot (CBS) was investigated in ´Natal´ sweet orange orchards. The first experiment was conducted during the 2001/2002 season and four isolates of B. subtilis (ACB-AP3, ACB-69, ACB-72 and ACB-77), applied every 28 days, alone or in combination were tested and compared with fungicide treatments. Two other experiments were carried out during the 2002/2003 season, where the same isolates of Bacillus and two isolates of Trichoderma (ACB-14 and ACB-40) were tested being applied every 28 days in the second experiment, and every 15 days in the third experiment. In the first experiment, the treatment with ACB-69 differed statistically from the control, but did not differ from... |

Citrus black spot (CBS) is a plant disease of worldwide occurrence, affecting crops in Africa, Oceania, and South America. In Brazil, climate provides favorable conditions and CBS has spread to the Southeast and South regions. CBS is caused by the fungus Guignardia citricarpa (anamorph: Phyllosticta citricarpa) and its control is based on the use of fungicides, such as benzimidazoles. In South Africa, the disease was kept under control for 10 years with benomyl, until cases of resistance to high concentrations of this fungicide were reported from all citrus-producing areas. Azoxystrobin (a strobilurin) has been found effective in controlling phytopathogens, including CBS, in a wide range of economically important crops. The present study investigated in... |

Citrus black spot (CBS) was discovered in March of 2010 near Immokalee in Collier County. CBS may adversely impact citrus growers both through demand and supply impacts. This paper has focused on the demand side of the equation. The analysis has also focused on Florida honey tangerines and the market in California. This market accounts for about 17.7% of Florida honey tangerine sales. If Florida product were banned from California in fear of CBS spreading there, the FOB price for Florida honey tangerines is estimated to decline by $3.48 to $4.40 per box, all else constant. The on-tree price would be expected to decline by the same amounts. However, with respect to production costs, all else would not be constant. Growers would be expected to bear... |
