abstract
An experiment was conducted at Lake Alau, Maiduguri of Borno state (11^o50^’48.9^” N 13^o9.427^” E), Sudan Savanna and Toshia, Yunusari local government area of Yobe state (13^o 14^’56^” N 11^o 47^‘52^” E); Sahel Savanna Nigeria during the 2020/ 2021 dry season to determine the efficacy of Aqueous neem seed extracts (ANSE) and Mahogany seed extracts (MSE) and compared with cypermethrin (A synthetic pesticide commonly used by farmers in the two zones) in the management of tomato fruit; Helicoverpa armigera infesting tomato. The experiment was laid in randomize complete block design with three replications. The tomato variety Roma VFN was used and it was assigned to the main plot. Four treatments were used: ANSE at 50 grams per liter, MSE at 60 grams per liter, cypermethrin and control (un-treated plots) which were assigned to the sub-plots. Each block has four treatments and each treatment was replicated four times making a total of twelve plots per block. Data was recorded on the number of fruits, number of fruit-worm, number of bored fruits, number of un-bored fruits, weights of bored fruits and weight of un-bored fruits per plot. The results obtained showed significant effect of the botanicals and cypermethrin over the untreated control (P<0.01) at both zones. At both locations significantly (P<0.01) higher number of fruits, higher number of un-bored fruits, higher weights of un-bored, lower number fruit-worms, lower number and weights of un-bored fruits were recorded in plots treated with cypermethrin which were followed by ANSE, which was followed by MSE. The untreated controls recorded significantly (P<0.01) higher number of fruit-worms, higher number and weights of bored fruits. Further research is recommended on the synergistic effects of ANSE and MSE in the management of the fruit-worm on tomato and other vegetables such as garden eggs, etc.
