mungbean. When the previously fallowed plot was divided into eight subplots and
each of the same seven crops and radish was randomly assigned to them, the
active nematode population after one cropping remained checked also regardless
of the crop. Likewise, after one subsequent cropping of mungbean on all
subplots, the population increased, with increases also being more evident when
soybean or mungbean was the preceding crop. We conclude that the nematode,
particularly the egg population, could only be checked partly and temporarily
by nonhosts, carbofuran 3G and fallow. [ASJ

of the reniform nematode Rotylenchulua reniformis on some crop cultivars in
Fiji. FIJI AGRICULTURAL JOURNAL, v.44(2):61-66. [En] [En Abst] (A:PS)
A total of 69 crop cultivars [including mungbean, blackgram, peppers,
soybean, sweet potato and tomato] in 20 plant families were tested in the
greenhouse to determine their host status to the reniform nematode
(Rotylenchulus reniformis Linford and Oliveira, 1940). Of the crops tested, 15
were found to be non-hosts; these included broomcorn, maize, peanut, pineapple,
rice, sorghum, sugarcane, peppers and Xanthosoma. The number of eggs produced
per eggmass varied greatly among the susceptible crops examined. [AS]

of the reniform nematode on the growth of Dung, pawpaw, pigeon pea and sweet

At an inoculum level of 40,000 larvae per pot, Rotylenchulus reniformis,
significantly reduced the growth of mungbean, pawpaw, pigeonpea, and sweet
potato in the greenhouse. Lower inoculum levels were inconsistent in their
effect, causing reduction in some plants only. Initial inoculum levels and
final population counts were always negatively correlated. [AS]

on some cultivars of cowpea and green gram. INTERNATIONAL NEMATOLOGY NETWORK
NEWSLETTER, v.3(3):8-10. [En] (A:PS)
One mungbean variety and seven cowpea varieties were evaluated for their
reaction to the reniform nematode (Rotylenchulus reniformis) using artificial
inoculation. Mungbean was the most suitable host allowing maximum invasion,
female development and egg production. Reaction of the cowpea cultivars ranged
from highly resistant to susceptible. [EMS]

Relative susceptibility of seventeen mungbean as well as blackgram
varieties against Rotylenchulus reniformis were tested in replicated pot
culture experiments. The mungbean varieties, ML-80, ML-62, TT-8E, Pusa-103,
PDM-14 and blackgram cultivars, Ratnapur-1, UG-201, and UG-135 showed resistant
reaction. Reactions of other varieties were moderately resistant to highly
susceptible. [AS]
