“…1). Similarly, Reddy et al (2020) also suggested neem-based formulations as effective. The laboratory study extended to the field condtions focused on the larval damage, adult infestation (oviposition) and % plant mortality on post application of last spray.…”

“…Use of botanicals for stem weevil management can be of use to develop ecofriendly IPM. Botanical pesticides are emerging as promising one now (Reddy et al, 2020), as these are environment friendly (Bhagawati et al, 2009;Awasthi et al, 2016). Using neem oil (Azadiracta indica), crude extract of Lantana camera and Gliricidia sepium are known to be effective against O. longicollis (Irulandi et al, 2009); also monocrotophos (4ml/ plant) in combination with azadirachtin (2ml/ plant) by stem injection proved to be more effective compared to monocrotophos.…”

This study evaluated the laboratory and field efficacy of some biopesticides against the banana pseudostem weevil Odoiporus longicollis (Olivier). Sprays were applied five times from 3rd to 11th month at 45 days intervals. The observations such as the oviposition marks, larval galleries, plant death and yield revealed 100% mortality in Avaya and chlorpyriphos and 91.66% in CTCRI-Nanma and neem based product Nimbicidine treatments. The field observations indicated that Nimbicidine and cassava based Nanma significantly reduced the infestation similar to positive control chlorpyriphos, and these were considered under 1st category. The botanicals Zimmu plant extract, gallic acid and Aavya (2nd category) and pongamia and neem soap (3rd category) provided moderate/less protection. It is concluded that the neem based botanical formulations could be effective and safe to use in banana against stem we evil.

“…For decades, banana crop was treated with pseudostem injections of monocrotophos, phorate, carbofuran, quinalphos, cypermethrin, dimethoate and triazophos (Kannan et al, 2021). Insecticides were injected into the stems of plants at monthly intervals from the fifth to seventh month of crop age (Reddy et al, 2020). However, in India, pesticides previously used in bananas, such as monocrotophos and triazophos, were restricted/banned(Central insecticide board and registration committee, 2022).Emamectin benzoate, a green insecticide compound effective against pseudostem borer, is now used by farmers in major banana-growing districts of Tamil Nadu in India.Emamectin benzoate is a macrocyclic lactone insecticide derived from the aver-mectin series of natural products (Dybas et al, 1989).As a foliar insecticide, it acts by stimulating the release of γ-aminobutyric acid to inhibit neurotransmitters, causing insect paralysis and subsequent death, and protects crops from coleopteran (Grosman and Upton, 2006) and lepidopteran pests (Jansson et al, 1996).…”

Emamectin benzoate has been frequently used in the banana ecosystem to combat the damage of pseudostem weevil. Therefore, the present study was conducted to validate the method, to assess harvest time residues and monitor emamectin benzoate residues in mature banana peel and pulp samples through LC-MS/MS. The validated method was used to determine emamectin benzoate residue in market banana samples. The study used Waters Alliance LC and Acquity TQD with an electrospray ionization interface in the positive ion mode. An isocratic flow of 0.1% formic acid (HCOOH) in water and 0.1% HCOOH in acetonitrile (CH3CN) was utilised for separation. CH3CN was utilised to extract emamectin benzoate residue from the samples, and a dispersive solid-phase extraction technique was used for subsequent cleanup. Linearity tests were performed with standard solutions containing 0.01 to 0.1 g mL-1, with three replicates for each concentration. For mature banana peel & pulp and mature banana pulp matrices, satisfactory recoveries of 79.85 to 95.09% and 89.20 to 100.94%, respectively and high precision relative standard deviations of 0.56 to 2.34% and 2.33 to 6.88%, respectively were obtained. For mature banana (peel and pulp, pulp alone) fruits, the lower detection and quantification limits were (0.003, 0.008), and (0.002, 0.007). The validated approach was utilised to analyse mature banana fruit samples obtained from emamectin benzoate treated fields and banana samples purchased from the local market. Results showed satisfactory validation of parameters like linearity, the limit of detection and quantification, and recovery for determining emamectin benzoate residues in banana fruit.
