Management of Tomato Yellow Leaf Curl Virus (TYLCV) Infecting Tomato by using Calcium Rich Compounds

Abstract

Bemisia tabaci (whitefly) transferred Tomato yellow leaf curl virus (TYLCV) disease is a significant constraint on tomato productivity. One technique for managing the condition is to spray calcium compounds (calcium carbonate, calcium chloride, calcium nitrate) onto tomatoes. According to the research findings, the incidence of TYLCV was lower in calcium compound sprayed plants than in control plants. The control group had the greatest TYLCV prevalence. Calcium carbonate-treated plants had the lowest TYLCV, followed by calcium nitrate-treated plants. Temperature and relative humidity were shown to be strongly linked with the population of whiteflies, the TYLCV vector in the tomato field. The expansion of TYLCV in tomatoes and the growth in whitefly populations were shown to have positive and substantial connections. In terms of plant height, fresh shoot weight, dried shoot weight, and root length, the three calcium compounds outperformed the others. Furthermore, the number of fruit/plants in the calcium carbonate spray was shown to be higher than in the control. With a few exceptions, calcium carbonate and calcium nitrate treatments were shown to be superior to calcium chloride treatments in terms of increasing growth and yield, contributing to character as well as yield.
