ECO-FRIENDLY MANAGEMENT OF LEAF MINER AND FRUIT BORER IN TOMATO

Abstract

The experiment was conducted under the central farm of Sher-e-Bangla Agricultural University, Dhaka in order to assess the efficacy of some promising botanicals against tomato leaf miner and tomato fruit borer. There were seven treatments and three replication per treatment used in a randomized complete block design (RCBD). The treatments were Neem leaf extract, Datura seed extract, Garlic bulb extract, Mahogany seed extract, Black pepper seed extract, Alamonda leaf extract and control. In case of leaf infestation by tomato leaf miners, the lowest leaf infestation (2.08% per plant) during the vegetative stage was obtained from neem leaf extract and the highest leaf infestation (10.19% per plant) was obtained from the control treatment (untreated). Similarly during fruiting stage, the lowest miner induced fruit infestation (3.18% per plot) was obtained from neem leaf extract whereas; the highest fruit infestation (14.64% per plot) was obtained from the control treatment (untreated). The lowest number of tomato fruit borer infested fruits in early, mid and late fruiting stage was 2.67, 5.63 and 4.48 fruits per plot which are obtained from neem leaf extract. On the other hand, the highest infested fruits were obtained from control treatment (11.33, 16.28, and 13.55 fruits per plot) respectively. However, in terms of healthy fruits per plot and weight of healthy fruits per plot, highest yield was obtained from neem leaf extract in all fruit bearing stages. Current study will help in botanicals control of tomato leaf miner and tomato fruit borer in tomato plants.
