Yellow mosaic disease (YMD) affects several types of leguminous crops, including the Vigna species, which comprises a number of commercially important pulse crops. YMD is characterized by the formation of a bright yellow mosaic pattern on the leaves; in severe forms, this pattern can also be seen on stems and pods. This disease leads to tremendous yield losses, even up to 100%, in addition to deterioration in seed quality. Symptoms of this disease are similar among affected plants; YMD is not limited to mungbean (Vigna radiata L. Wilczek) and also affects other collateral and alternate hosts. In the last decade, rapid advancements in molecular detection techniques have been made, leading to an improved understanding of YMD-causing viruses. Three distinct bipartite begomoviruses, namely, Mungbean Yellow Mosaic India Virus (MYMIV), Mungbean Yellow Mosaic Virus (MYMV), and Horsegram Yellow Mosaic Virus (HgYMV), are known to cause YMD in Vigna spp. Vigna crops serve as an excellent protein source for vegetarians worldwide; moreover, they aid in improving soil health by fixing atmospheric nitrogen through a symbiotic association with Rhizobium bacteria. The loss in the yield of these short-duration crops due to YMD, thus, needs to be checked. This review highlights the discoveries that have been made regarding various aspects of YMD affecting mungbean, including the determination of YMD-causing viruses and strategies used to develop high-yielding YMD-resistant mungbean varieties that harness the potential of related Vigna species through the use of different omics approaches.

Tomato (Solanum lycopersicum L.) is one of the most important Solanaceous and remunerative vegetable crops. However, despite its value in fresh and processing markets, many farmers are concerned about pest resistance. Therefore, looking to the seriousness of pest menace particularly leaf curl and fruit borer, research is needed to reduce the chemical pressure and establish an ecological equilibrium in tomato fields. A combination of bio-intensive pest management (BIPM) and chemo-intensive pest management (CIPM) were followed trap crop marigold (Tagetes erecta L.) and yellow sticky traps to manage these pests during 2016-2017 and 2017-2018. The percent plant infestation with leaf curl (0.6-0.9) and fruit infestation with fruit borer (5.2-6.7) were observed in BIPM and CIPM. In these fields, the application of insecticides increased yields 30-38.3%. There was 47.1-56.8% higher net return in BIPM and 59.5-68.9% higher in CIPM than farmers' practices. Similarly, benefit cost ratio was analyzed 2.5:3.6 in BIPM and 2.5:3.7 in CIPM.
