Progress in recurrent selection and in crossing cultivars with white clover resistant to the clover root‐knot nematode Meloidogyne trifoliophila
TLDR
A recurrent selection programme for resistance to the clover root‐knot nematode (Meloidogyne trifoliophila) assessed individual white clover genotypes for the number of root galls and root dry weight and found survival of the resistant group of lines was poorer than other groups. Expand
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.
TLDR
Culture and identification of root-knot nematode populations from sites in the North Island of New Zealand showed that M. trifoliophila is more widespread and abundant than M. hapla, and differential resistant and susceptible galling responses among half-sib families of white clover from a breeding program indicated that all M.trifoliophile populations tested were of the same pathotype.

Effectiveness of recurrent selection of white clover (Trifolium repens) for resistance to New Zealand populations of clover cyst nematode (Heterodera trifolii)
TLDR
Results indicate that development of a white clover cultivar resistant to H. trifolii is achievable and that the resistance will be effective against the nematode in most of New Zealand. Expand
Evaluation of 15 Trifolium spp. and of Medicago sativa as Hosts of Four Meloidogyne spp. Found in New Zealand.
TLDR
The predominant root-knot nematode in New Zealand pastures is Meloidogyne trifoliophila, identified until recently as M. hapla, while the host range of these two species on legumes and on clover species closely related to Trifolium repens is needed. Expand
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
