Oryza glaberrima plant multiple different varieties, to suite varying microhabitats and to stagger the harvest. A 2006 survey showed that a village typically cultivated 25 varieties of rice; an individual household would on average have 14 varieties and grow four per year; this, however, is down from the seven to nine varieties per woman that was average in previous decades. Women, who are traditionally responsible for the seeds, trade them often over long-distance networks. Varieties, each with subtypes, include: The cultivars the Africa Rice Center calls TOG 12303 and TOG 9300 have low shattering, and thus yields comparable with low-shattering Asian rice
Saluria inficita the plants show dried up shoots and turn yellow. Damage can controlled by hand picking, pheromone usage, light traps and usage of chemical insecticides such as carabaryl, methyl parathion, phosphomidon or dimethoate. Saluria inficita Saluria inficita, the white stem borer, is a moth of the family Pyralidae. The species was first described by Francis Walker in 1863. It is found in India and Sri Lanka.
