The infections created by the nematode can serve as external opening facilitating fungi and bacteria colonization, causing wet rot.

S. bradys belongs to the family Hoplolaimidae and is described as vermiform nematode when mature, measuring about 1 mm in length with a well-developed stylet.

[citation needed] Eggs are laid in soil or plant tissue where they hatch and the juveniles develop into adults by moulting.

[5][6][7] Siam weed (Chromolaena odorata), roselle (Hibiscus sabdariffa), yam bean (Sphenostylis stenocarpa), and pigeon pea (Cajanus cajan) are also considered moderate hosts.

In a recent study, the use of porcupine jointvetch (Aeschynomene histrix), Mexican marigold (Tagetes erecta), stylo (Stylosanthes guianensis), velvet bean (Mucuna pruriens) and kudzu (Pueraria phaseoloide) intercropped with yam have shown to potential to reduce S. bradys population.

It is important to note that in tubes not showing obvious external symptoms of damage, it is necessary to scrape away the surface layers to determine the presence of dry rot.

Four granular nematicides (aldicarb, oxamyl, carbofuran and miral) applied as post-plant sidedressing treatments effectively reduced the nematode population during the growing season and significantly increased yield without toxic accumulation in the harvested tubers.
