[10] D. opuntiae has been effective against the weedy prickly pear Opuntia stricta, [10] and D. austrinus is used to control Opuntia ...
There are three typical ways to cultivate nopal cacti — commercial plantations, family farms and gardens, or in the wild. Approximately 57,000 hectares (140,000 acres) are used to produce prickly pear fruit, 10,500 hectares (26,000 acres) for the pads production, and 100 hectares (250 acres) to cochineal production.
Common English names for the plant and its fruit are Indian fig opuntia, Barbary fig, cactus pear, prickly pear, and spineless cactus, among many others. [3] In Mexican Spanish, the plant is called nopal, a name that may be used in American English as culinary terms. Peninsular Spanish mostly uses higo chumbo for the fruit and chumbera for the ...
