Progress in recurrent selection and in crossing cultivars with white clover resistant to the clover root‐knot nematode Meloidogyne trifoliophila
Abstract New Zealand pastures are generally deficient in clover content due in part to root‐invading nematodes. A recurrent selection programme for resistance to the clover root‐knot nematodeExpand
INTERSPECIFIC COMPETITION BETWEEN PINUS RADIATA AND SOME COMMON WEED SPECIES— FIRST-YEAR RESULTS
A trial designed to quantify the reduction in Pinus radiata D.Don seedling growth caused by competition from a range of important weed species was established at Rotorua, a moist North Island site,Expand
Evaluation of FSCBG — An Aerial Application Simulation Model
To provide data for evaluation of a model known as FSCBG (Forest Service, Cramer, Barry, Grim), an optical tracer spray was aerially applied to a flat, grass covered area along a single flight line.Expand
Host-Parasite Relationships of Meloidogyne trifoliophila Isolates from New Zealand.
Root-infecting nematodes are commonly found on white clover in New Zealand pasture where they reduce yield, nitrogen fixation, and persistence. The dominant root-knot nematode on white clover in NewExpand
Effectiveness of recurrent selection of white clover (Trifolium repens) for resistance to New Zealand populations of clover cyst nematode (Heterodera trifolii)
Selections of white clover resistant or susceptible to Heterodera trifolii in earlier rounds of a recurrent selection programme were intercrossed and selected in three further rounds of selection.Expand
Evaluation of 15 Trifolium spp. and of Medicago sativa as Hosts of Four Meloidogyne spp. Found in New Zealand.
The predominant root-knot nematode in New Zealand pastures is Meloidogyne trifoliophila, identified until recently as M. hapla. Clarification was needed on the host range of these two species onExpand
NOZZLES FOR MINIMISING AERIAL HERBICIDE SPRAY DRIFT
Three nozzle types were compared in a trial investigating the potential for herbicide drift during aerial spraying. Water containing a colorimetric tracer, a fluorimetric tracer, and a foaming agentExpand
