crinkle virus by different plant extracts. INDIAN PHYTOPATHOLOGY,

The purpose of this study was to screen some of the plant extracts for
exploiting their antiviral properties to blackgram leaf crinkle virus. The
results showed that all the plant extracts used in the experiment had some
influence on the suppression of disease in the case of in vitro mixing. Plant
extracts differed in their activity and highest percentage of inhibition
(58.13%) with 1 hr incubation period was obtained from zinger extract which in
2 hr incubation was found in turmeric (57.15%). Similarly, lowest inhibition
upto 14.29% was found in jute extract at exposure of 1 hr incubation and in 2
hr incubation 16.94% inhibition was obtained in a weed Ipomoea glaberrina. It
was observed that increasing incubation periods increased the inhibition
percentage. [PLHJ

Pre and post-virus-acquisition starvation of Aphis craccivora Koch. and
Acyrthosiphon pisum Harris resulted in appreciable increase in percentage of
transmission of blackgram leaf crinkle virus. Highest transmission occurred
when aphids were starved for 90 min prior to virus-acquisition. A. pisum and A.
craccivora on 20 and 80 min of post-acquisition starvation and 10 and 20 min of
virus-acquisition inoculated more number of plants. Both the aphids transmitted
the virus in probes lasting for one min. However, beyond 5 min of successive
transfer on test plants loss in transmissibility was apparent. Viruliferous
aphids off the plant retained the virus for a much longer period than on maize
plants. The virus appears to be non-persistently borne in the aphids. [AS]
