Resistance Management & IPM
On the Equator, where much of the world’s floriculture industry resides, the growing season is all year round increasing the chances of over-use of pesticides and the prospects of resistance. Implementation of biological controls on the Equator has proved highly successful in Kenya and growers in Ethiopia, Ecuador and Columbia are also beginning to implement biological control programs.
The use of biological controls will reduce the amount of pesticide sprays. Unless this transition is properly managed, however, it could also increase resistance by narrowing the range of sprays which can be applied. This is due to the need to protect predators and parasitoids from being killed by non-compatible sprays. However, with good advice from experienced consultants such programs are possible.
