This study was carried out on the evaluation of different essential oils and biocontrol agents against Alternaria alternata the causal agent of fruit rot. For the pathogenicity test against A. alternata was performed through cut and injection inoculation methods. The antifungal potential of different essential oils like turpentine, laung, neem and castus root was carried out at different doses i.e. 5, 10 and 15% by food poisoned method to find out the effective and suitable oil for the growth inhibition of A. alternata and evaluate the effect of some biocontrol agents on growth inhibition of A. alternata. The findings of this investigation stated that cut method of inoculation showed higher percentage (2.60) of rotting as compared to injection method of inoculation (2.35). Minimum colony growth of A. alternata (31.60, 21.25 and 15.16%) was examined under Laung oil at the dosage of 5, 10 and 15% followed by Neem oil (42.60, 31.60 and 21.30%), respectively. Maximum colony growth of A. alternata (62.71, 52.40 and 41.75%) was observed under Castus root oil at the dosage of 5, 10 and 15%. Zero growth of target pathogen was examined under Turpentine at 5, 10 and 15%. Under control the A. alternata showed (90 mm) colony growth. Minimum linear colony growth of A. alternata was observed for Hypoxylon Sp1 (50.31%), followed by Neurospora spp. (52.97%), Lasiodiplodia theobromae (54.7%), Chactomium subaffine (57.07%) and Fusarium sp. (65.4%). Maximum mycelial colony growth (90%) was recorded in control. Based on present investigation, Similarly, for controlling the linear colony growth of A. alternata under in vitro conditions Turpentine oil ranked 1st, Laung oil ranked 2nd, Neem oil ranked 3rd, Castus root oil ranked 4th.

Phomopsis Vexans

The experiments were conducted at Laboratory of the Department of Plant Pathology and in the farm of Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh during Rabi season of the year 2007-2008. Four fungicides viz. Bavistin 50 WP (Carbendazim), Tilt 250 EC (Propiconazole), Cupravit 50 WP (Copperoxychloride) and Dithane M-45 (Mancozeb) and micronutrients (Gypsum, ZnO and Boric acid) were evaluated against Phomopsis vexans causing Phomopsis blight and fruit rot of eggplant. The fungicides and micronutrients either applied individually or in combination showed significant effect in terms of per cent leaf infection, fruit infection, leaf area diseased and fruit area diseased in comparison to control. Effect of each fungicide applied in combination with micronutrients always showed better performance in reducing disease incidence and disease severity than the fungicides applied alone. Among the fungicides, Bavistin 50 WP (0.1%) proved to be effective arresting the spore germination and mycelia growth of Phomopsis vexans assayed in in vitro test. Reduction of leaf area diseased caused by Bavistin 50 WP (0.1%) in combination with micronutrients were 58.17, 67.37, 78.41 and 85.25%, respectively at preflowering, post-flowering, fruiting and fruit ripening stages while Bavistin 50 WP (0.1%) alone reduced by 52.22, 58.67, 74.19 and 83.09%, respectively at those stages. Similarly reduction of fruit area diseased caused by Bavistin 50 WP (0.1%) in combination with micronutrients were 57.93 and 79.79%, respectively at fruiting and fruit ripening stages while Bavistin 50WP (0.1%) alone reduced by 56.93 and 76.14%, respectively at those stages. Micronutrients had little effect against the disease but significantly better than control.Int. J. Agril. Res.
