Controle da podridao parda do cacaueiro com novas formulacoes de fungicidas a base de cobre empregados a alto e baixo volumes
Experiments were undertaken on cocoa farms considered as focal black pod disease areas, to test the efficiency of new fungicide formulations. Two oil formulations of copper oxichloride were tested at low spray volume. The metalic copper content of these were 17 per cent (Duriac) and 25 per cent (Kauritol). A high spray volumes, a further formulations of copper oxichloride of a 30 per cent metalic copper (Coprantol) 300 FW was used. These fungicide were tested against standard copper oxichloride and cuprous oxide formulations of a 50 per cent metalic copper (oxicloreto Sandoz and Cobre Sandoz, respectively), the copper oxichloride was applied in low and high volume whereas the latter at high volume. The results, indicated that Duriac, Kauritol e Coprantol 30 FW, were was efficient as in the control of the disease as standard Oxicloreto Sandoz and Cobre Sandoz applied at low and high volume respectively and superior to Oxicloreto Sandoz applied at high volume. The new formulations in terms of quantity of metalic copper/tree was 50 per cent less than that used in high volume applications with a weattable powder formulation
