Abstract
The experiment was conducted in the farm of Sher-e-Bangla Agricultural University,
Sher-e-Bangla Nagar, Dhaka-1207 during the period from October 2018 to March,
2019 to evaluate the ecofriendly pest management of tomato (BARI Tomato-14). The
experiment consisted of six different ecofriendly treatment along with untreated control
and was laid out in Randomized Complete Block Design (RCBD) with three
replications. The seven treatments were T

= Untreated control, T
= Neemoil
suspension spray, T

= Garlic oil, T

= Black seed oil, T

= Marigold intercropping, T
=
Netting at seedling stage, T
=Tobacco leaf powder extract spray. The data were
statistically analyzed by MSTAT-C and means were separated by Duncan’s Multiple
Range Test (DMRT) test at 5% levels of probability. Four insect pests were found in
tomato cultivation viz. white fly, aphid, fruit borer and leaf miner. The lowest number
of white fly per plant (3.13, 3.01 and 2.49) and the highest control percentage of white
fly (87.89, 89.31 and 89.31) was observed in treatment T

at vegetative, flowering and
reproductive stage. The lowest number of aphid per plant (1.20, 1.20 and 1.01) and the
highest control percentage of aphid per plant (94.23, 94.41 and 94.98) was found from
treatment T

at all stages of plant. At the vegetative, flowering and reproductive stage,
the lowest number of fruit borer per plant (1.02, 1.61 and 0.90) and the highest control
percentage of fruit borer per plant (90.04, 90.65 and 91.59) was found from treatment
T

. The lowest number of leaf minerper plant (0.69, 0.60 and 0.65) in treatment T
and
the highest control percentage of leaf minerper plant (93.52, 87.27 and 84.69) was
found from treatment T
. Number of fruit, Individual fruit weightand yieldof tomato
varied significantly due to different treatment and the highest yield (55.28 t ha

)
wasobtained from T

.Treatment T
was the most suitable for controlling white fly,
aphid, fruit borer and leaf minerand yield of tomato was also highest in treatment T

as
compared to other 6 treatments.
