| dc.description.abstract | The present investigation was carried out at CRC of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Distt. Udham Singh Nagar (Uttarakhand) to check the “Effectiveness of some chemicals as well as cow urine based insecticides against insect pests of soybean and their impact on coccinellids and spiders.” Soybean is an important legume providing 43 per cent protein and 20 per cent oil. It is attacked by 273 insect pests, hampering the crop production. Thus it is necessary to control them. Result showed that overall defoliator population (tobacco caterpillar, green semilooper, Bihar hairy caterpillar) was effectively checked by indoxacarb @ 150 ml/ha, chlorpyrifos @ 0.3% and Kamdhenukitnashi @ 1% and 2%. Bihar hairy caterpillar(Spilarctia obliqua) was effectively controlled by Kamdhenukitnashi @ 1% and 2%. While, larval population of Spodoptera litura was brought down by Kamdhenukitnashi @ 8% and indoxacarb @ 150 ml/ha. Similarly, indoxacarb @ 150 ml/ha and chlorpyrifos @ 0.3% provided good control of larval population of Thysanoplusia orichalcea. Imidachlorpid @ 250 ml/ha and Kamdhenukitnashi @ 1% and 2% were very effective treatments against whitefly. Seed treatment with the Thiamethoxam @ 3 g/kg seeds reduced the stem fly infestation effectively. Imidachlorpid @ 250/ha, indoxacarb @ 150 ml/ha and Kamdhenukitnashi @ 8% showed good performance against the girdle beetle infestation. Among different treatments Kamdhenukitnashi @ 2% and indoxacarb @ 150 ml/ha were comparatively safer for spiders while, Thiamethoxam seed treatment @ 3 g was safer for coccinellids. Maximum grain yield was recorded from the plots with chlorpyrifos seed treatment @ 4 ml/kg seeds. Also, treatments with Kamdhenukitnashi displayed some yield boosting chgaracteristics. Benefit cost ratio was higher in chlorpyrifos seed treatment and Kamdhenukitnashi spray @ 1, 2, 5 and 10%. Thus, from present investigation it is revealed that use of Kamdhenukitnashi can become a important eco-friendly components of the integrated pest management module for insect pests associated to soybean crop. | en_US |
