Diseases of Linseed and Fibre Flax
(Shipra Publications, New Delhi, 1997-01-01)
Linseed and flax are the varieties of the same plant (Linum usitatissimum L). When the plants are grown commercially for oilseed purposes, the crop is often referred to as linseed or flax seed or oilseed flax crop. It is ...
Effects of wetness period and temperature on development of dark pod spot (Alternaria brassicae) on oilseed rape (Brassica napus)
(1996-12)
In controlled environment experiments, when oilseed rape pods or leaves were inoculated with spore suspensions of Alternaria brassicae, the maximum disease incidence (proportion of pods or leaves diseased) increased as ...
Factors affecting the incubation period of dark leaf and pod spot (Alternaria brassicae) on oilseed rape (Brassica napus)
(1996-07)
Experiments to investigate the factors affecting the incubation period of dark leaf and pod spot (Alternaria brassicae) on leaves and pods of oilseed rape (Brassica napus) were done in controled environment (constant ...
The incorporation of pathogen spores into rain-splash droplets : a modelling approach
(1996-06-30)
Simple, theoretical, physical principles and existing experimental data were used to derive an analytical model to describe thr incorporation of plant pathogen spores into splash droplets, Data were obtained from experiments ...
Germination of Alternaria linicola conidia on linseed : effects of temperature, incubation time, leaf wetness and light regime
(1996-06)
Conidia of Alternaria linicola germinated on both water agar and linseed leaves (detached or attached) over a wide range of temperatures (5-25 degrees C) by producing one to several germ tubes. At temperatures between 10 ...
Oilseed rape : disease development, forecasting and yield loss relationships
(HGCA, 1996-02)
A series of fourteen replicated plot scale experiments was established between 1991 and 1994 to determine the effect of disease on the yield of winter oilseed rape and the economic threshold and optimum fungicide timings ...
Periodicity and gradients in dispersal of Alternaria linicola in linseed crops
(1995-11)
Conidia of Alternaria linicola produced on infected linseed crops were mainly dispersed by wind. The numbers of conidia in the air above linseed crops collected by a Burkard spore sampler were greatest between 12:00 h and ...
Effects of inoculum concentration, leaf age and wetness period on the development of dark leaf and pod spot (Alternaria brassicae) on oilseed rape (Brassica napus)
(1995-10)
Experiments were done under controlled environment and glasshouse conditions to study the effects of inoculum concentration, leaf age and wetness period on the development of dark leaf and pod spot (Alternaria brassicae) ...
Early development of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape (Brassica napus) in relation to temperature and leaf wetness.
(1995-08)
In controlled environment experiments to study early development of light leaf spot, lesions developed with leaf wetness durations of 16 to 48 h after inoculation of oilseed rape with conidial suspensions of Pyrenopeziza ...
