dc.description.abstract | Investigations were carried out on eco-friendly management of brinjal shoot and fruit borer, Leucinodes orbonalis Guenee through organic manures and bio-pesticides at Instructional Farm, College of Agriculture, Junagadh Agricultural University, Junagadh during Rabi 2011 and 2012. During the study, brinjal shoot and fruit borer, Leucinodes orbonalis Guenee was the major pest found infesting this crop in Junagadh area of Gujarat State. Studies on eco-friendly management of brinjal shoot and fruit borer, L. orbonalis through organic manures revealed that maximum (75%) requirement of the nitrogen by the crop provided through the neem cake combined with the inorganic fertilizers recorded the shoot infestation, fruit infestation on number and weight basis. While, FYM recorded the maximum population of natural enemies. Also, maximum yield of healthy brinjal fruits was recorded in the treatment where 75 per cent of the recommended dose of nitrogen was provided through neem cake. Considering the effect of organic manures on morphological characters of brinjal, the treatment where 50 per cent of the required nitrogen was provided through poultry manure and remaining through in inorganic form recorded the maximum plant height, number of leaves per plant, number of flowers per plant and number of fruits per plant. The studies on relationship between pest infestation and morphological characters of brinjal revealed that plant height, number of leaves per plant, number of flowers per plant and ABSTRACT Abstract number of fruits per plant exhibited the negative correlation with the shoot infestation, fruit infestation on number and weight basis. While, all the morphological characters showed positive correlation with shoot infestation, fruit infestation on number and weight basis. Study on bio-efficacy of bio-pesticides against brinjal shoot and fruit borer, L. orbonalis revealed that profenophos (40%) + cypermethrin (4%) 0.04 per cent, NSKE 5 per cent and neemazal 0.005 per cent were found most effective against the pest with minimum shoot and fruit infestation. The treatment of spinosad 0.01 per cent, emamectin benzoate 5 per cent and cartap hydrochloride 0.1 per cent were the next effective treatments against this pest. Significantly maximum yield of healthy brinjal fruits (29051 kg/ha) was recorded in the treatment of profenophos (40%) + cypermethrin (4%) 0.04 per cent, neemazal 0.005 per cent (28002 kg/ha) and NSKE 5 per cent (27261 kg/ha). The treatments with spinosad 0.01 per cent (26520 kg/ha), emamectin benzoate 5 per cent (25779 kg/ha) and cartap hydrochloride 0.1 per cent (25039 kg/ha) were included in the next group of effective treatments. The economics of two spray applications of profenophos (40%) + cypermethrin (4%) 0.04 per cent gave the highest net return followed by neemazal 0.005 per cent. Rest of the treatments viz, NSKE 5 per cent, spinosad 0.01 per cent, emamectin benzoate 5 per cent and cartap hydrochloride 0.1 per cent were the next economic treatments against this pest. Considering the cost benefit ratio of these treatment, neemazal 0.005 per cent and profenophos (40%) + cypermethrin (4%) 0.04 per cent gave the maximum cost benefit ratio. Thus, looking to the effectiveness and economics of different organic manures and bio-pesticides applied against major insect pests of brinjal, it can be concluded that maximum nitrogen requirement of the crop provided through the organic manures followed by two sprays of profenophos (40%) + cypermethrin (4%) 0.04 per cent, neemazal 0.005 per cent or NSKE 5 per cent were economic for the control of brinjal shoot and fruit borer, L. orbonalis | en_US |
