ECO FRIENDLY PEST MANAGEMANT OF TOMATO

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 1 = Untreated control, T = Neemoil suspension spray, T 3 = Garlic oil, T 4 = Black seed oil, T 5 2 = 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 7 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 2 2 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 2 . 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 2 ) wasobtained from T 2 .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 2 as compared to other 6 treatments.
