The utilization of an invader cactus weed as part of an integrated control approach


, : The utilization of an invader cactus weed as part of an integrated control approach. Proceedings of the VIII International Symposium on Biological Control of Weeds: 429-432

After the partially successful biological control programme against Opuntia ficus-indica in South Africa, approx. 50 000 ha remain moderately to heavily infested with this weed. Management of these remaining infestations rely partly on the continuous action of the introduced insect enemies and on chemical control methods. However, in the very dense infestations (approx. 8000 ha) the cost of control is prohibitive.
