EPIDEMIOLOGICAL PRINCIPLES OF CONTROL OF MANGO MALFORMATION

ABSTRACT

An epidemiological descriptor of mango malformation has been proposed and accordingly a control strategy has been envisaged. The disease is polycyclic, the pathogen, Fusarium maniliforme Sheld, is polyetic and host specific. Maximum fungal population was recorded during February–March while the highest disease incidence in July–November. Latent period extended from late November to early February. New crop of conidia (propagules) on host surface was formed during July–September. The disease was transmitted by vector (mites) and infected scions. The gradient of spread was steep. The plant to plant infection was slow. Logarithmic phase started at 1.34–5.01% disease incidence. Mean maximum disease incidence in regular and alternate bearers were 40–48 and 72–73%, respectively. Pattern of epidemic in former one was sigmoid while in the latter it was bimodal. Duration of the epidemic was year round. Thus, rate of plant to plant spread was slow, propagules for dissemination were available for short period. But tissues remained infectious for long and small amount of initial inoculum could start the epidemic. Therefore, rate of increase of the disease could be minimised through sanitation (pruning of infected plant parts, killing of the propagules with fungicides, using cultivars with vertical resistance and growing plants in dry weather condition).
