DEVELOPMENT OF IPM FOR NEW ZEALAND APPLE PRODUCTION |

| Abstract:
New Zealand apple production and the adoption of IPM techniques is dominated by the needs of the export market. With the current consumer concern about pesticides and uncertainty surrounding their future use, New Zealand must develop a range of IPM options for apple growers. The present organophosphate (OP) programme is being improved to reduce residues and combat pest resistance, while maintaining integrated mite control. A new synthetic pyrethroid and OP programme uses mite predators resistant to both chemical groups. Mating disruption of tortricids is playing an increasing role in their control and in resistance management. Insect growth regulators offer potential for control of the whole pest complex, more selectively than with conventional chemicals. Biological fruit production is a new research programme based on biological methods of pest control, including insect pathogens, mating disruption and natural enemies. All these programmes aim to maintain high fruit quality standards while meeting quarantine requirements. | |
