Pre-harvest fungicide sprays for the control of postharvest diseases of mango.

In field trials conducted in South Africa over 2 seasons (1990-92), Jun. (pre-flower) applications of copper-oxychloride followed by monthly applications of copper-oxychloride, from fruit-set onwards, effectively controlled anthracnose caused by Colletotrichum gloeosporioides [Glomerella cingulata]. Winter applications of copper-oxychloride controlled soft brown rot (Hendersonia creberrima). Further applications from fruit set onwards did not improve disease control, suggesting that the infection was systemic. Various systemic fungicides were screened in combination with copper oxychloride for the control of anthracnose and soft brown rot. All treatments controlled both diseases.
