The effects of foliar diseases and irrigation on root development, yield and yield components of wheat (Triticum aestivum L.)
(Lincoln College, University of Canterbury, 1985)
Studies were conducted on three field trials of wheat cv. Kopara to investigate the lack of compensation by later determined components of yield because of early disease constraints. The investigation was based on the ...
Epidemiology and crop loss assessment for disease management in winter wheat (Triticum aestivum L.)
(Lincoln College, University of Canterbury, 1984)
The epidemiology of Mycosphaerella graminicola (Fuckel) Schroeter was studied for two seasons and the role of ascospores as primary inoculum of the disease was examined as a basis for the development of control measures. ...
Disease management of Ascochyta fabae Speg., a seed borne pathogen of Vicia faba L.
(Lincoln College, University of Canterbury, 1984)
Ascochyta fabae was present in all the field and broad bean crops surveyed in the Canterbury and Marlborough areas during the 1978/79 and 1979/80 seasons. In broad bean crops, the disease incidence on the flowering nodes ...
A physiological approach to disease yield loss relationships in barley (Hordeum vulgare L.)
(Lincoln College, University of Canterbury, 1987)
Methods for estimation of crop losses caused by disease are based largely on empirical models. Recently there has been an increased awareness that a more mechanistic approach with a greater understanding of the physiological ...
