Conteúdo: |
Cassava is affected by more than 20 pathogens in Brazil, including fungi, bacteria, virus, nematodes and protozoa. Bacteriosis, caused by Xanthomonas campestris pv manihotis, used to be considered the most important disease. It has been shown that disease does not cause significant damage in regions where the mean temperature is above 25 degree C, even on highly susceptible cultivars. Anthracnose, caused by Colletotrichum gloeosporioides, can be highly destructive when it is associated with the presence of highly virulent strains of this fungus and long periods of rain. Superelongation, caused by Sphaceloma manihoticola, has been reported in the Amazon and recently in the northern parts of the State of Mato Grosso. Only a few cultivars were susceptible to thisdisease, Brown leaf spot, caused by Cercosporidium manihotis, and brown large, spot caused by Cercospora vicosae, occur in all regions where cassava is grown. These diseases can reduce crop production in susceptible cultivars by more than 30 percent. Root rots are caused by several fungi, but Phytophthora drechsleri is considered the most important causal agent. Phytophthora root rot was found only on cassava grown on very humid lowlands or on heavy clay soils during the rainy season. Without standardized methods of inoculation and evaluation of resistance to each pathogen, it will not be possible to obtain reliable information on the nature of this complex disease. |
