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.

Abelmoschus esculentus (L.) Moench, commonly known as ‘ladies finger’ or ‘bhindi’ is an economically important common vegetable crop cultivated throughout the tropical and warm temperate regions of the world. Induced mutation is highly effective in enhancing natural genetic resources and has been used in developing improved cultivars. The effect of gamma irradiation on various morphological and yield attributing characters in M2 generation were studied.

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).

The major production constraint for okra is yellow vein mosaic disease, causing losses with regard to the quality and as well as the yield. This is a viral disease occurring on bhendi. Yellowing of the entire network of veins in the leaf blade is the characteristic symptom. In severe infections, the younger leaves turn yellow to become entirely chlorotic and the plant is highly stunted.

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.

Global positioning system survey map is an indicator to locate the nature of disease spread so as to conclude the hotspot areas. Yellow mosaic disease on greengram caused by begomovirus genus of the family geminiviridae. Present investigations on field survey for disease incidence, diagnostic symptoms and its spatial distribution in major greengram growing parts of North Eastern Karnataka through Global positioning system (GPS) system during kharif 2015..

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.

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.
