| dc.description | 1. Total four sprays as per treatments were undertaken at 15 days interval starting from 15 days after emergence of the crop. 2. Observations on defoliators (semilooper Chrysodeixis acuta , tobacco leaf eating caterpillar Spodoptera litura, and hairy caterpillar Spilosima obliqua if any) and natural enemies, lady bird beetle, chrysopa, and spider was recorded 24 hours before and after 3,7,10, and 14 days after each sprays. 3. The Observations on the larval population of defoliators was recorded from each one meter row length (mrl) by randomly selecting five spots of one meter row length in each plot and average number of larvae /mrl was worked out. 4. Observations on natural enemies was recorded by randomly selecting five plants from each net plots and average number per plant were calculated separately. 5. The yield data from each plot was recorded at maturity stage. 6. The data thus obtained from the above experiment was subjected to statistical analysis after appropriate transformation. Lastly economics and the ICBR of various treatments were calculated. | en_US |
| dc.description.abstract | The present investigation entitled: “Evaluation Of Microbials And Botanicals Against Defoliators Of Soybean” was conducted during Kharif season of 2016 at Experimental Farm of Department of Entomology, Post Graduate Institute, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Treatments reveled that Beauveria bassiana and Nomuraea rileyi each @ 7.5 g / l and neem seed extract 5 % were most effective in reducing the population of green semilooper and tobacco leaf eating caterpillar as well as registered highest yield of soybean. Dashparni extract 12.5 ml / l was least effective in reducing the semilooper population and higher yield of soybean. Further, this treatment was not effective against Spodoptera litura. The neem seed extract 5 % was economically most effective treatment against soybean defoliators followed by N. rileyi @7.5 g/l. | en_US |

| dc.research.problem | The present investigation entitled “Evaluation of microbials and botanicals against defoliators of soybean” was carried out at Research Farm, Department of Agricultural Entomology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, during Kharif 2016 with a view to evaluate the microbials and botanicals against defoliators. The data obtained during the present investigation were subjected to statistical analysis by standard procedures and discussed as under. The results obtained in the present study are presented following objectives. 1) To evaluate the efficacy of microbials and botanicals against defoliators of soybean. 2) To see the effect of treatments on natural enemies. 3) To work out the ICBR of the various treatments. | en_US |

| dc.theme | Microbials and botanicals bio pesticide play an important role in crop protection and other uses in future. Microbials and botanicals have to face tremendous computation after invention of newer generation of synthetic insecticide with minimum risk to non target organism. Detail insight the study of evaluation of microbials and botanicals against defoliator of soybean will help in tapping most effective control option for pests of soybean like lepidopteron pests. microbials and botanicals are organic in nature so there is less chance of development of resistance as they are biodegradable and are free toxic residues. | en_US |
