Conteúdo: |
This study has the aim of presenting a forest management system to be applied on small farms, especially in the settlement projects of the Brazilian Amazon (Acre state, Brazil), and to examine its sustainability by investigation the responses of the forest in terms of the changes in natural regeneration in felling gaps and the dynamics of the residual trees. Using the program CAFOGROM, an additional aim was to simulate the forest responses to different cycle lengths, harvesting intensities and silvicultural treatments to determine the theoretical optimum combination of theses parameters. |

Phytophthora citrophthora and P. nicotianae var. parasitica are considered to be the most serious soil borne disease affecting citros in Brazil. Biological control of Phytophthora in the orchard is a management option that may ofter potential. Trichoderma spp. are well documented as effective biological control agents, including some pythiaceous fungi. Two isolates of Trichoderma harzianum (Th. 13 and Th. 9) and one isolate of T. koningii (TK.3), Isolated from Sclerotinia sclerotiorum sclerotia, were evaluated against different isolates of Phytophthora in vitro and in a greenhouse bioassay. Isolates Th.13 and Th.9 parasited both Phytophthora species. Isolate Tk.3 completly inhibited the mycelial growth of Phytophthora. Isolate Tk.3 produces a toxic metabolite that inhibit the growth of Phytophthora. Isolate Th.9 consistently was superior to all other isolates in reducing the root disease. Citros seedlings survived an average of 90% whereas those in the contol survived only 30-50%. |
