Cost of root disease on white clover growth in New Zealand dairy pastures
DNA-based testing indicated that Aphanomyces trifolii, a root pathogen of subterranean clover, may be present in the dairy-pasture soils, and the control of soil-borne root pathogens in New Zealand pasture is a direct means to increase profitability. Expand
Application of circular economy principles to New Zealand pastoral farming systems
Global food production is under pressure to produce more from limited resources, with further expectations to reduce waste and pollution and improve social outcomes. Circular economy principles aimExpand
Quantifying the economic cost of invertebrate pests to New Zealand’s pastoral industry
ABSTRACT The invertebrate pests most commonly affecting New Zealand’s pastoral-based production in ‘average’ years cause losses of between $1.7B and $2.3B p.a. of which up to $0.9B occur on sheep andExpand
Internal biosecurity between islands: identifying risks on pathways to better manage biosecurity threats
Research found that soil intercepted from used machinery destined for the Chatham Islands contained a range of plants, insects and nematodes, but the number and diversity of these taxa varied with the source of contamination. Expand
Parasitism effects on white clover by root-knot and cyst nematodes and molecular separation of Heterodera daverti from H. trifolii
Histological examination of nitrogen-fixing root nodule tissues revealed that the nematodes established their permanent feeding sites in the vascular bundles of nodules which appeared enlarged deformed and disorganised by the expansion of nematode feeding cells and hyperplasia of the nodule cortex.

Plant-parasitic nematodes on pasture in New Zealand
Progress made in white clover breeding programs in New Zealand is summarized and advances in genetic mapping and introgression as they affect resistance to nematodes are examined, together with observations which suggest that root-feeding nematode have little impact on yield and that the animal toxicity associated with Anguina seed galls in Australia is absent.

White clover vegetative persistence under pressure : sharpening New Zealand ’ s competitive edge
White clover is relied upon as a cornerstone of the international competiveness of New Zealand’s pastoral sector, despite its vegetative persistence and yield being constrained by pests and diseases.Expand
The Programmed ApproachTM to pasture renewal and cropping.
opportunity to control perennial weeds and also breaks pest cycles. Despite the benefits to be gained from pasture renewal, around 50% of New Zealand farmers renew less than 2% of their pastures eachExpand
Effects of Nematicides and Plant Resistance on White Clover Performance and Seasonal Populations of Nematodes Parasitizing White Clover in Grazed Pasture
Root-infecting nematodes are a major cause of white clover, Trifolium repens, not reaching its potential in New Zealand pastures. Resistance and/or tolerance are the preferred control options.Expand
