Efficacy of pesticides against mango aphid, Toxoptera aurantii (Boyer de fonscolombe)

BIOINFOLET - A Quarterly Journal of Life Sciences (2014)

D. Srinivasa Reddy M. Latha L. Rajesh Chowdary Lokendra Kumar

The mortality of mango aphid (Toxoptera aurantii) ranged from 54.33 to 100%. Profenophos 50EC (0.1%), dimethoate 30EC (0.06%), acephate 75 SP (0.075%), acetamaprid 20 SP (0.004%), monocrotophos 36 SL (0.054%) recorded 100% mortality while least mortality (54.33%) was observed with dichlorovas 76EC (0.152%).

Performance of Groundnut Genotypes (Arachis hypogaea L.) for Yield and Yield Attributing Characters Suitable for Rainfed Tracts of Prakasam District of Andhra Pradesh

The Andhra Agricultural Journal (2023)

P. Haritha L. Rajesh Chowdary B Pramila Rani A Mounica

A field experiment was conducted to evaluate groundnut genotypes suitable for Prakasam district at Agriculture Research Station, Darsi in kharif, 2022.Sixteen groundnut varieties including four superior checks were evaluated for different quantitative traits.Randomized complete block design with three replications was used in the experiment.Days to 50% flowering, plant height, seed pod -1 , 100 seed weight (gm), and seed yield kg ha -1 significantly differ among different genotypes.TCGS1862 genotype took maximum days to flowering while the lowest days took by TCGS 2233; maximum plant height was observed in K2313 while the minimum height was observed in TCGS1872, TCGS1862.Maximum weight of 100 kernel were recorded by TCGS2117 and the early maturity were recorded by Dharani (C ) while the late maturity was recorded by TCGS2117 and high shelling percentage were recorded by Dharani (C ) while low recorded by K1736 and TCGS1872,which produce high yield while the lowest yield observed by TCGS211.Based on results ,the recommended ground nut variety for adaptation and further research in the rain fed agro climate area TCGS1872 and TCGS1862 were found suitable.

Baseline Susceptibility of Spodoptera litura to rynaxypyr, a New Insecticide Molecule of Anthranilic diamide Group

Indian journal of plant protection (2011)

L. Rajesh Chowdary Arunkumar Hosamani M. Bheemanna

Laboratory experiment was carried out during 2009–10 to generate a baseline data for efficacy of new molecule rynaxypyr 20 SC of anthranilic diamide group against tobacco caterpillar, Spodoptera litura (Fab.). Susceptibility index worked out for F1 and F6 generations revealed that, susceptibility of Spodoptera litura increased after six generations in insecticide free exposure and susceptibility index for LC50 was 1.5.

First Report of Stem Borer (Xylotrechus smei) Occurrence on Red Sanders Plantations of Tamil Nadu and Gujarat, India

Journal of Scientific Research and Reports (2024)

K. N. Ashrith M. A. Noushad Maria Dominic Savio M.L. Rajesh Chowdary

This communication presents the first documented case of the stem borer Xylotrechus smei (Cerambycidae: Coleoptera) infesting red sanders in Tamil Nadu and Gujarat, India. The pest was detected in red sanders plantations located in Dharmapuri and Tenkasi districts of Tamil Nadu, as well as in Surat, Navsari, and Tapi districts of Gujarat, India, during August 2023. In both regions, young red sanders trees aged between 2 to 16 years were affected, with incidence levels varying from 2.24% to 10.86% in the affected plantations. Signs of infestation include the presence of galleries, bore holes in cut stems, complete drying, and mortality of the trees. Initially, larvae feed on the bark, and as they mature, they tunnel through the cambium and wood, impeding nutrient flow and leading to tree mortality. The larvae's deep tunneling within the wood makes them difficult to eradicate with pesticides. Adult beetles typically emerge in peak numbers during April to May and November to December, coinciding with their mating period and selection of host plants for egg-laying. This report aims to outline the damage caused by the stem borer in red sanders and document ongoing monitoring efforts to support interim management strategies.

Survey on dimensions of insecticide usage pattern and management of shoot and fruit borer, Leucinodes orbonalis (Guenee) in brinjal growing areas of Nellore District

Deleted Journal (2020)

Lokendra Kumar M Kavitha R. V. S. K. Reddy L. Rajesh Chowdary

The roving survey was conducted during 2018-19 using well structured questionnaire format to document insecticide usage pattern adopted by the farmers to manage Leucinodes orbonalis in five major brinjal growing mandals of Nellore District of Andhra Pradesh state. Among different group of insecticides belonging to slightly to highly hazardous toxicity class the highest usage of Chlrorantriniprole 18.5 SC (37.50%) was reported followed by Emamectin benzoate 5 SG (34.0%) and lowest usage of 6.50 per cent was reported Chlorpyriphos 20 EC, Tolfenpyrad 15%EC and Neem oil 1% EC in all mandals of Nellore District. The average number of insecticides application ranged from 16.10 to 28.32 rounds of sprays. Maximum numbers of 28.32 sprays was recorded from the Chammadapalem village of Gudur Mandal with an spray interval of 8.28 days and lowest number of sprays was recorded from Chillakuru village (16.10 sprays) with 5.84 days of spray interval. Around (62.0%) Farmers from different mandals approached pesticide retail shops to get information on pesticide recommendation and farmers (90.50%) did not pay attention towards label information given in pesticide containers. In different mandals, around 32.0 per cent of farmers sprayed pesticides at recommended dose and nearly 92.50 per cent famers carried spraying operations during morning hours and most of the farmers (63. 50%) used single insecticide for spraying. Around 34.0 per cent of the farmers did not follow any waiting period and harvested fruits on the same day after pesticide application. Majority of the farmers (82.0%) have done spraying only after observing initial symptoms and only (4.5%) have done spraying above ETL. In all the mandals (91.0%) farmers relied only on Insecticides and only 9.0 per cent famers followed cultural control methods for BSFB control.
