Abstract:

An experiment was conducted to evaluate the effectiveness of plant materials against yellow mite (Polyphagotarsonemus latus) on jute (Corchorus olitorius) cv. 0–9897 in both greenhouse and field condition at BJRI during the period from March to October 2016. In greenhouse premises, the highest mortality (69.39, 67.77, 63.86, 62.43 and 61.47%) was recorded in extract of neem seed kernel @ 1:20, mehogony seed, pithraj seed, turmeric powder and green neem leaf, respectively.

Neem is known for its therapeutic and pesticidal applications. Azadirachtin is the chemical constituent in neem seed kernel which is active against wide spectrum of insect pests. Beside azadirachtin several other chemical constituents such as salannin, meliantriol, etc., are also known to possess biocidal activity. The azadirachtin content in seed kernel generally varies between 0.1% to 0.7% and is determined using reverse phase high-pressure liquid chromatography (HPLC) system. For commercial application azadirachtin content 1500 ppm in extract-based and 300 ppm in oil-based products is an im

Abstract:

The cashew tree (Anacardium occidentale L.) is a vital crop in tropical regions, yet its production and productivity are hindered due to pest infestation, particularly by the tea mosquito bug (TMB) (Helopeltis spp.), causing substantial yield losses. The present study was carried out during 2019–2023 at Kerala Agricultural University, Regional Agricultural Research Station, Pilicode, Kasaragod, Kerala to evaluate the effectiveness of various botanical and natural products in managing TMB infestation in cashew. The variety selected for the study was Madakkathara. The experiment was laid out in
