Evaluation of different Insecticides against Sucking Pests Infesting Brinjal
Abstract
Afield experiment was conducted at Agricultural Research Station, S. D. Agricultural University, Ladol during 2019-20, 2020-21, 2021-22 and 2022-23 for evaluation of different insecticides against sucking pests infesting brinjal. The eleven different treatments were evaluated. There was no any sucking pest infestation in kharif 2019-20. Based on pooled data of three years, Sulfoxaflor 21.8 SC 0.03 percent @ 12.5 ml/10 liter of water recorded minimum whitefly and jassid population (2.79/leaf and 1.21/leaf), no effect on predator and highest yield (286.61 q/ha) followed by Sulfoxaflor 21.8 SC 0.024 percent @ 10 ml/10 liter of water and Cyantraniliprole 10.26 OD 0.0072 percent @ 7.02 ml/10 liter of water.

Introduction
Brinjal, solanum melongena L. also known as eggplant belong to family solanaceae is cultivated in almost all the seasons across India. Brinjal is often described as the ‘King of vegetables ‘due to its versatility use in Indian food (Choudhary and Gaur, 2009). India is one of the largest producers of brinjal in the world. Due to its nutritive value, consisting of minerals like iron, phosphorous, calcium and vitamins like A, Band C, unripe fruits are used primarily as vegetable in the country. Brinjal is subjected to attack by number of insect pests right from nursery stage till harvesting (Regupathy et al., 1997). Among them, shoot and fruit borer, Leucinodes orbonalis (Guen.), whitefly, Bemicia tabaci (Genn.), leafhopper, Amrasca biguttula biguttula (Ishida) and red spider mite, Tetranychus macfurlanei (Baker and Pritchard). Of these, sucking pests is considered as one of the main constraints as it damages the crop throughout the year. The extensive and indiscriminate use of pesticides for controlling brinjal pests has led to several problems like resurgence of secondary pests, health hazards and pesticide residues inedible fruits (Kabir et al., 1996). The objective of the present investigation is to test the efficacy of newer insecticides for the management of sucking pests of brinjal.
Conclusion
Sulfoxaflor 21.8 SC 0.03 percent @ 12.5 ml/10 liter of water recorded minimum whitefly and jassid population, no effect on predator and highest yield and proved to be the most effective treatment against sucking pests of brinjal.
