has increased in recent years due to the concern about the use of hazardous
pesticides. The present study was carried out during the year 2011-12 at University
of Guyana, Guyana with the objective of using vermiwash produced from different
plant sources against tomato fruit fungus and growth of tomatoes. Vermiwash
was produced using bagasse, neem and paddy straw in different combinations )T1
to T9( and was used as foliar spray on tomato plants with respective treatments.
Plant growth parameters and effect of vermiwash produced from different plant
materials were used against tomato fruit fungus Alternaria alternata
were monitored during the study. The findings from this experiment indicated
that vermiwash with combination of neem+earthworm+cattle dung in T3, T6 and
T7 were very effective depending on their concentration or percentage to get
rid of pathogens and improve yield and growth parameters of tomato fruit. The
treatment T1, T2, T6, T7, T8 and T9 at 10% dilution of vermiwash were effective
against A. alternata affecting tomato fruits. At 5% dilution there was
no inhibition of A. alternata, T7 had a maximum of 12 colonies and T1
on the other hand had a maximum of 5 colonies. At 10% dilution growth of
A. alternata were killed for most treatments except T3, T4 which consisted
of two colonies each and T5 a colony count of 6. At 15% dilution there was growth
of A. alternata in all treatments except T8. Maximum growth was observed
on petri plates containing T1 and T2 with a count of 8 colonies and a minimum
growth of one colony present in T7. At 20%, growth of A. alternata was
observed in all treatments. The maximum growth was seen in T1 with 27 colonies
and minimum growth in T5 with 1 colony. This indicated that at a concentration
of 10% vermiwash would more likely to inhibit growth or kill the A. alternata.]]>Ananthakrishnasamy, S., S. Sarojini, G. Gunasekaran and G.
