Immuno-nucleobased diagnosis of Tospoviruses infecting tomato and its reactions on different tomato genotypes

Abstract

Tospoviruses are phytopathogens responsible for significant worldwide crop losses.Tospoviruses are emerging threats of tomato production in globally. The present study was undertaken to identify tospoviruses and their interaction with vector population in Bangladesh which help to develop a durable integrated control package. Among the member of tospoviruses infecting tomato Groundnut bud necrosis virus (GBNV) has been identified based on DAC-ELISA and PCR from Godagari, Rajshahi District with the percent disease incidence 55 to 80%. We tentatively identified Thrips palmi as a vector of GBNV in Bangladesh. Thirteen varieties of tomato has been tested against GBNV and revealed that most the tomato varieties are susceptible against GBNV. The percent disease incidence has been observed 20 to 100 % among the tested BARI released tomato varieties.
