Yellow mosaic virus disease
-
Screening of okra genotypes was carried out under four different environments for shoot and fruit borer, yellow vein mosaic virus disease and enation leaf curl virus disease. The genotypes responded differently to different environments against different insect-pests and diseases. None of the genotype was found free from shoot and fruit borer infection, YVMV and ELCV incidence. However the genotypes that were found with some degree of resistance might be used for future breeding programmes.

Pulses are rich and the cheapest source of delivering protein and also valuable animal feed. Indian has the largest area of about 34% and total production of about 26% of pulses globally. The present investigation was carried out with four parents in Diallel mating design during 2010-2011.

Studies in this regard and epidemiological aspects of MYMV are scanty in the North Eastern Karnataka region. Hence the studies were conducted to know the influence of weather parameters on whitefly population and MYMV incidence.

Biological evidence on host range of yellow mosaic disease of greengram [Vigna radiata (L.) Wilczek]
The study was conducted to know the alternate hosts of Mungbean Yellow Mosaic Virus (MYMV) disease on greengram by cross inoculated with virus on several crops and weed hosts under laboratory through insect vector whitefly (Bemisia tabaci).

Disease score was recorded at maturity stage by counting number of infected plants in each line and the per cent disease incidence was calculated. The disease intensity was scored adopting the following 1-9 score (Singh et.al., 1988) (Table-1). On maturity 100 random plants of each entry selected and harvested separately from which the average plant yield of each entry calculated.

Field screening of 5 mungbean varieties for resistance against whitefly, induced Mungbean Yellow Mosaic Virus (MYMV) was carried out during Rabi and Kharif on 2014. Population of whitefly ranged from 3.22 to 7.69 per plant while MYMV incidence ranged from 6.00 to 39.00 per cent during Zaid 2014. Only one variety Pant Moong-1 was found to be resistant to whitefly during Zaid 2014.

Studies were conducted on the performance and morphological characterization of okra for yield and YVMV disease. None of the genotypes found complete free from YVMV infection. However, on scoring test few of them got resistant mark for YVMV like IIHR 129, IIHR-123, and IIHR 120. The characters like plant height, plant canopy, fruit yield per plant, PDI and CI have found wide variation. The character’s association revealed that the association of traits is not only due to genes but also due to the favorable impact of environment.

Mungbean is one of the most important pulse crops which is native to India. The yield of mungbean has been stagnant over years. Improvement in yield of mungbean is becoming difficult mainly due to the occurrence of pest and diseases.

Green gram and Black gram genotypes/germplasms were evaluated to identify the sources of resistance to leaf spot, powdery Mildew and mung bean yellow mosaic virus (mymv) diseases. Screening was done under natural field conditions at Regional Agricultural Research Station (RARS), Warangal, Telangana State, India.

Hundred genotypes of mungbean were screened against Mungbean Yellow Mosaic Virus (MYMV) disease. Among hundred genotypes screened, three genotypes namely LGG-593, KMP-24, and KMP-40 were found moderately resistant, nineteen genotypes viz., KMP-4, KMP-22, VBN-2-3, LGG-594, MGG-40-1, JNG-13, TK-6-1, BGG-1, VBN-2-3, LGG-410, LGG-410, KKM3-1, ICC-12947, LGG-592, KMP-1, KMP-22, KMP-23, KMP-17 and KMP-4 found moderately susceptible, sixty-six genotypes found susceptible and twelve genotypes were found highly susceptible.

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.

Field experiments were conducted during Kharif 2016 and 2017 to manage yellow vein mosaic virus in Okra with seven modules along with one control. The module consists of use of either seed treatment or yellow sticky trap singly or in combination with neem oil (bio-pesticide), one insect growth regulator and two new generation insecticides to manage the vector population of whitefly which transmit the disease.

Survey of Sathgudi sweet orange was done in the Nagri village of Chittor district in the A.P. state during November, 2006. Incidence of citrus yellow mosaic disease was observed up to 50% in citrus plants. A few plants also showed unusual symptoms of vein clearing and mosaic. Bacilliform and flexous rod shaped of virus particles were seen in electron microscopy in samples of the diseased citrus plants showing vein clearing and mosaic.
