Description
The role of pests, pathogens and beneficial organisms in temperate pasture and animal production is highlighted. Significant differences between pests and. the severity of their infestations exists between the Northern and Southern Hemispheres, because both pasture and pest species and their natural enemies have been carried by colonists to the New World countries in the Southern Hemisphere, Pests and pathogens place significant constraints on the sustainability and productivity of pastoral agriculture. Acquisition of basic databases and development of a wider range of controls has occurred over the past 25 years, but the effort has been disjointed. Knowledge of the more complex interactions of pests and pathogens with other invertebrates and micro-organ.isms, including antagonistic and symbiotic species, their host plants and grazing animals, is at an early stage of development and offers many fertile areas for research. With the exception of lucerne pests and some pasture pest problems in New Zealand integrated pest management (IPM) is poorly developed·. To achieve synthesis of 1PM, research on pasture pests will need to be better focused in order to quantify the various biological, • ecological, damnge and control parameters and their interactions with agricultural practices. Research administrators and politicians who fund research will need to recognise the long-term nature of such research. Pests and pathogens have major affects on social attitudes of farmers, but these have not been adequately researched. Likewise the impacts of pests and pathogens are not well documented. Research will need to address the inadequacy of current databanks on most pests and pathogens. Considerable oppouunity exists for improvement of pest and pathogen management systems by: quantitative development of biological control opportunities, including utilisation of endophytic fungi in grasses; use of plant molecular biology in development of multiple gene resistance; selective use of pesticides, to protect environments and reduce product contamination; application of grazing management to control problems;.and quantitative development of 1PM.
