The field experiment was conducted in field at Regional Research Center, Amravati during Kharif season of 2012-13, 2013-14 and 2014-15. The topography of experiment site was fairly uniform, leveled and have medium black soil. The experiment was laid out in Randomized Block Design with four replications consisting of eight treatments comprising of control (T1), humic acid 6 per cent (T2), 100 per cent recommended dose of fertilizers (T3), 75 per cent recommended dose of fertilizers (T4), 50 per cent recommended dose of fertilizers (T5), humic acid 6 per cent spray schedule +100 % recommended dose of fertilizers with humic acid 6 per cent (T6), humic acid 6 per cent spray schedule +75 % recommended dose of fertilizers with humic acid 6 per cent (T7), humic acid 6 per cent spray schedule +50 % recommended dose of fertilizers with humic acid 6 per cent (T8). Soil application mixing with fertilizer @ 2.5 lit per ha at the time of along with basal dose (full dose of N, P, K) were given to the treatment T6, T7 and T8 only. From the three years pooled data, it can be conclude that significantly highest grain and straw yield (2065 and 2890 kg ha-1, respectively) of soybean was obtain with application schedule humic acid 6 per cent at different growth stages of crop with 100 per cent RDF along with 2.5 lit/ha of humic acid 6 per cent as soil application at the time sowing but found at par with higher dose of treatment i.e. T7.Keywords

N. rileyi formulated in different carriers viz., talc, kaoline, charcol, wheat bran, soil and lignite stored at 4°C and room temperature for six months storage to assess viability and infectiveness against third instars larvae of H. armigera. All carriers retained the viability in sufficient numbers for a period of 150 days at 4°C temperature. However, after 180 days of storage significant reduction was observed in all carriers. Kaoline supported maximum propagules i.e. 14.21 x 106 cfu/g followed by lignite (11.95 x 106 cfu/g) after 180 days of storage at 4°C temperature. Viability was drastically reduced when carrier's formulations stored at room temperature. Kaoline formulation stored at 4°C was efficient as recorded maximum larval mortality of H. armigera at 60, 120 and 180 days followed by lignite. However, at room temperature drastic reduction in per cent larval mortality of H. armigera (ranged of 16.67 to 43.33%) was observed.Keywords

Red whitefly fungus, Aschersonia aleyrodis (Webber) is a fungal pathogen of nymphs of blackfly, Aleurocanthus woglumi (Ashby) and whitefly, Dialeurodes citri (Ashmead) on the citrus plant. It is used as a promising biological control agent. In the present study, attempts have been made to check the efficacy of A. aleyrodis biopesticides for the management of citrus blackfly and whitefly under laboratory condition. Probit analysis for LC50 values of 2nd instar nymph was calculated 1.1 x 108 spore/ml and 1.8 x 107 spore/ml and LT50 values, 8.14 to 13.77 days and 6.88 to 9.72 days were derived for 2nd instar nymph of citrus blackfly and whitefly at respective concentration. Cross infectivity was found non-pathogenic to citrus aphids and mealybugs. Among the insecticides, Dimethoate 30 % EC was observed compatible with A. aleyrodis as it shows less inhibition at the half and recommended dose of insecticide.Keywords
