Arab Journal of Plant Protection, 39(1): 79-83. Tomato is an important vegetable crop, belongs to the family Solanaceae and is the second most consumed vegetable following potatoes. The tomato crop is grown all over the world in both summer and winter seasons, and plant viruses are a major threat to tomato production. Among these viruses, tomato leaf curl virus (TLCV) causes considerable yield loss to tomato crop. This virus is transmitted by a whitefly (Bemisia tabaci) vector. In this study, the effect of TLCV infection, on the following tomato growth and yield parameters, was evaluated: plant leaf number and area, plant biomass, plant height, root length, and plant stem diameter and yield. Tomato plants were transplanted in wellprepared plots with 4 replications. The control group was covered with polyethene bag to avoid whitefly infestation. Plants were scored on the 15th and 30th day after inoculation and TLCV disease severity was recorded. Analysis of variance (ANOVA) showed the significant differences between the healthy and infected tomato plants. Moreover, growth and yield parameters were reduced with the increase in disease incidence, disease severity and whitefly infestation. Disease severity was increased with the increase in temperature during the growing season. It can be concluded from this study that TLCV significantly affects growth and yield of the tomato crop. Keywords: Tomato, Tomato leaf curl virus, TLCV, disease incidence, disease severity.

Tomato leaf curl virus (TLCV) is one of the most devastating and widely distributed viruses in the tomato crop, transmitted through whitefly in nature. Disease incidence and severity of TLCV were monitored on four tomato varieties/lines. Tomato leaf curl disease was managed through three non-chemical treatments viz., compost, nutrient enrich compost and multi-nutrients. The incidence of TLCV was found in the range of 57% to 70%. Among all the tomato varieties/lines, VRI-49 was moderately resistant, Nagina and Money Maker were susceptible, and VRI-20 was found to be highly susceptible against TLCV. Compost (44.02±3.26c) was the most effective way to suppress the progression of disease severity. Environmental factors (Max. and Min. temperatures, Relative humidity and Rainfall) showed significant correlation with disease development. Treatments were able to suppress the disease development even in the presence of favorable environmental conditions. The increase in relative humidity increased the disease progression significantly.

The tomato crop is affected by various biotic and abiotic factors. Among the biotic factors, Tomato Leaf Curl Virus (TLCV) is one of the most devastating viruses of tomato. The virus belongs to Begomovirus and family Gemniniviridae. The genome of virus is single-stranded-DNA. It is naturally transmitted through whitefly (Bemisia tabaci). The virus is responsible for causing severe economic losses up to 80% in tomato crop-growing regions and continuously threatening the tomato crops. The increasing severity of TLCV has compelled plant virologists to develop accurate detection and identification of the virus. TLCV is responsible for certain biochemical changes and considerably affecting the plant growth. Tomato Leaf Curl Virus is significantly influenced physiological parameters and metabolic activities of all tomato varieties. The biochemical changes of cellular components are caused due to morphological deviation of infected virus plants, and symptoms expressed by the plants can determine the magnitude of the vegetable losses. It is evident from the previous reports, that nutrients were effective in reducing TLCV from a tomato plant. Moreover, the usage of resistant varieties and controlling of whitefly population and management of TLCV by different nutrients are some of the economical and recommendable ways to manage TLCV. Among the organic management strategies, the compost is also considered best in suppressing disease severity. Moreover, epidemiology plays a vital role in the spread and progress of the disease. Keeping in view the importance of TLCV and its effects on tomato crop, the present review will highlight the etiology, physiology and management of TLCV.

The experiment was conducted to check the effects of biochar and different priming agents on whitefly transmitted tomato leaf curl virus. Biochar was applied to potting mixture at 1%, 2% and 3% concentration. In order to check the effects of priming, tomato seedlings were primed with NaCl, glycerine and distilled water at three concentrations. After biochar application 22.43% disease severity was recorded that was significantly lower than control (40.12%). In graft inoculated plants, disease severity was in 15.32% while in control 50.23% disease severity was recorded. From primed seedling NaCl and glycerine shows good results then distilled water. In case of biochar, disease reduction was more at higher concentration (3%) than other two concentrations. Priming gave better results in case of whitefly inoculation.
