芒果炭疽病通过炭疽病菌的水生分生孢子在芒果体内传播。小调。在叶片、落叶枝条顶端、木乃伊花序和花苞的病斑中产生分生孢子。在炭疽病生长旺盛和花朵发育期间，从这些来源捕获的分生孢子被捕获在果园中。大多数分生孢子是从幼叶的病斑中捕获的。分生孢子是在实验室从叶斑中的尖头孢子在较宽的温度范围内(10-30℃)产生的。C)在潮湿和潮湿(95-97%[相对湿度])条件下。分生孢子在整个季节都会在树内扩散。大量分生孢子在长时间的降雨期间被捕获，当分生孢子在生长活跃或开花期间发生时，就会记录到严重的疾病暴发。露水后未捕获分生孢子。结球藻变种的子囊孢子在果园疾病活跃时，未成年人没有被困住。这些孢子显然对芒果炭疽病的侵染循环没有贡献。
Anthracnose disease spreads within mango trees by waterborne conidia of Colletotrichum gloeosporioides var. minor. Conidia were produced in lesions on leaves, defoliated branch terminals, mummified inflorescences and flower bracts. Conidia were trapped from these sources in the orchard during periods when anthracnose disease was developing both in flush growth and in flowers. The majority of conidia were trapped from lesions in young leaves. Conidia were produced in the laboratory from acervuli in leaf lesions over a wide temperature range (10-30.degree. C) both in wet and humid (95-97% [relative humidity]) conditions. Conidia would be present for dispersal within the tree throughout the entire season. Large numbers of conidia were trapped during prolonged periods of rain, and when these occurred during active growth or flowering, severe outbreaks of disease were recorded. No conidia were trapped following dews. Ascospores of Glomerella cingulata var. minor were not trapped while the disease was active in the orchard. These spores apparently do not contribute to the infection cycle of mango anthracnose.
