“…Furthermore, the use of bio-pesticides like M. anisopliae and B. bassiana in treatment modules has shown commendable performance in reducing shoot infestation due to L. orbonalis. This aligns with findings reported by Nayak et al (2013) and Phukon et al (2014) and showcasing the effectiveness of M. anisopliae and B. bassiana against brinjal shoot and fruit borer.…”

A study was conducted to evaluate different treatment modules against the brinjal shoot and fruit borer, Leucinodes orbonalis Guenee, in the AKLB-9 variety of brinjal crops. The research took place in the field at the Department of Entomology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the Kharif season of 2019-20. The primary objectives were to assess the performance of various modules against the major insect pests of brinjal and to determine the relative safety of botanicals, bio-pesticides, bioagents and chemicals to natural enemies. Four treatment modules were tested using a randomized block design. These modules involved actions such as seedling dipping, removal of infested shoots, release of beneficial insects and application of different substances at specific intervals. The first application of each module occurred on Days After Transplanting (DAT) 20 and 60, with subsequent applications at 10-day intervals. Observations were made on the infestation of brinjal shoot borer and its natural enemies, including cumulative percentages of shoot and fruit infestation, at 3, 7 and 10 days after each spray. Average population of natural enemies per plant was also recorded. Additionally, the study evaluated the yield and Incremental Cost-Benefit Ratio (ICBR) of the different treatment modules for cost-effectiveness. Results indicated that Treatment Module 2 was the most effective against brinjal shoot and fruit borer, while Treatment Module 3 showed promise in minimizing shoot infestation. Modules 1 and 4 were observed to be safer for natural enemies like ladybird beetles. Treatment Modules 2 and 3 were found promising in minimizing fruit infestation, with Module 1 found to be safer for spiders. Treatment Module 2 emerged as the most effective and economically viable, recording an ICBR of 1:60.98. These findings contribute valuable insights into sustainable pest management practices for brinjal cultivation.

“…Spinosad 48 SC was found to be the most effective insecticide for the control of H. armigera, followed closely by indoxacarb15 EC. Phukon et al, (2014) revealed the reduction in fruit damage was up to 92.20 per cent in cypermethrin treated plot followed by 91.12 per cent, 88.74 per cent and 87.01 per cent in the plots treated with Neem oil, B. Bassiana and M. Anisopliae, respectively due to H. armigera larvae over control. The highest increase in yield over control was noticed in cypermethrin treated plots (62.85%) followed by neem oil treated plots (41.83%).…”

“…Researchers proved that neem (oil) is as effective as cypermethrin in controlling the tomato fruit borer, Helicoverpa armigera (Hb.) on tomato (Phukon et al 2014). Neem products can be readily combined with many other bioagents including microbes (Mohan et al 2007).…”

Background Entomopathogens are frequent natural enemies of arthropods worldwide, and they are capable of alternative control agents against the important pests. The optimally selected botanical product can minimize their harmful effect on these entomopathogens, and it becomes essential to know the influence of combinations of botanicals and biopesticides (botanical biopesticide combination (BBC)) in comparison to their sole action. Main body Botanicals, especially neem products, are highly efficient to be combined with the entomopathogens (with some exceptions). There are many possible reasons for the synergistic action of these botanicals, attacking the immune system of the insect being one of the important ones. These botanicals when applied in combination with microbial pesticides showed maximum sublethal effects rather than complete mortality, making them the best alternatives for combating resistance development in insects. To work effectively, biological control agents must be used within a compatible program combined with botanicals. It is highly difficult for such products to compete with chemical controls in high-value crops, so where they can become a commercially viable option in organic cultivation. The increasing acreage is under organic production for high-value export crops, where pesticide residues are undesirable for the environment, and biopesticides and botanicals are good choices for crop protection. Concerning the effect of these products used in pest control, a significant reduction in dosage in relation to the individuals is noticed. Conclusion By combining the performance and safety, biopesticides and botanicals are efficacious. This knowledge should facilitate the choice of biopesticides compatible with less harmful or naturally occurring botanicals. And if these have to be incorporated into a pest management program through an organic approach, it is necessary to determine the effects of botanicals on the beneficial microbes, on the behavior of pest, the importance of application technique, and the role of application timing for these botanical biopesticide combinations.
