Studies on major in sect pests of fenugreek and their management
Abstract
The studies conducted at the College of Horticulture, UHS Bagalkot on fenugreek resulted in exploring 37 phytophagous species, out of which 35 are the new reports to fenugreek ecosystem. Among the phytophagous species, Spoladea (=Hymenia) recurvalis (Fabricius), Spodoptera litura (Fabricius), Agrotis segetum (Denis and Schiffermuller) and Spilarctia obliqua (Walker) were predominant defoliators. Since, the defoliators affect the valuable product i.e leaf, a field experiment on major insect pests of fenugreek and their management was laid out in a randomized block design during 2013–14. The experiment consisted of ten treatments, among all the treatments the green labeled new molecules viz., emamectin benzoate 5 SG @ 0.25 g per l, indoxacarb 15.8 EC @ 0.25 ml per l and fipronil 5 SC @ 1 ml per l were found to be very effective in minimizing the larval population and in reducing foliage damage throughout the period of experiment. The treatments also resulted in fetching higher leaf yields 14.14, 14.42 and 14.58 tonnes per ha.
