Soybean yellow mosaic virus disease

The field experiments carried out to study the effect of border crops and insecticides against whitefly transmitted Yellow Mosaic Virus (YMV) in soybean during kharif 2015-16 and 2016-17. The treatment in combination of maize as border crop, seed treatment with thiamethoxam 30FS@5ml/kg seed, foliar application of imidacloprid 17.8 SL @ 500ml/ha at 30-35 DAS and triazophos 40 EC @ 800 ml/ha at 45-50 DAS recorded lowest mean whitefly population (1.02 whiteflies/plant), which resulted in reduced YMV disease incidence (14.63%) and highest grain yield (19.42 q/ha) among treatments in soybean.

Yellow Mosaic Virus disease (YMD) is a serious viral disease of soybean. Considering a very less attempt in studying the disease this investigation was carried out in order to arrive at the genetic basis of Yellow Mosaic Virus disease resistance of soybean. Crosses were made between highly resistant soybean varieties (DS 9712 and DS 9814) and two highly susceptible varieties (JS 335 and MAUS 609).

Forty-three genotypes of soybean were screened for soybean yellow mosaic virus disease (SYMV) under glasshouse condition using viruliferous whiteflies (Bemesia tabaci) through artificial virus inoculation method. Among 43 genotypes none of the genotypes were found highly resistance to the disease. Eleven genotypes viz.
