Abstract:
Tomatoes (Solanum lycopersicum) are one of the most commercially important
vegetables grown worldwide. Tomatoes are an important vegetable crop. It is a rich
source of vitamins, minerals, and fiber, as well as nutritional antioxidants.
An experiment was conducted to evaluate the effect of an integrated pest management
system on disease and pests on tomato (Solanum lycopersicum) grown under poly
tunnel conditions at Glorious Holdings (PVT) Ltd, Kandana, Sri Lanka, with the
objective of evaluating the effect of integrated pest management system on disease and
pests on tomato grown under poly tunnel conditions. The research was laid out in
completely randomized design (CRD) with four treatments, and ten replicates of each
treatment. The treatments combinations were as Tl - control- without using any pest
and disease management, T2- using organic pest and disease management, T3 - using
inorganic pest and disease management, T4 - integrated pest and disease Management.
The results indicated a significant effect of the pest and disease management in
treatments observations were recorded for number of branches, height of plants (cm),
number of flowers, number of fruits, number of pests and diseases leaves
The highest number of branches (36.9) was recorded in T+. The maximum height
(137 .4) was recorded in T+. The highest number of flowers (31.5) was recorded in T+
and the lowest (2.6) recorded by Tz. The maximum number of fruits (7.6) was recorded
in T+. Minimum number of fruits (0.9) was produced by Tr (Control).The treatment T+ is
the most effective treatment in controlling whiteflies up to 12 weeks. The treatment T+
is the most effective treatment in controlling aphids up to 12 weeks. Tz, Tz and T+
treatments are effective in controlling caterpillars. The treatment T+is themost effective
treatment in management of leaf curl disease up to 12 weeks. T4 treatment are
especially effective in early blight disease management up to 12 weeks.T4 treatment
are effective powdery mildew disease management also up to 12 weeks. Among the
four treatments, Ta demonstrated the highest efficiency and is recommended as the
preferred pest and disease management practice for the growth and quality production
of tomato.
