Studies on the development of fruit rot of tomato caused by Alternaria solani (Ellis &Mart.) Jones &Grout

Abstract

During the regular survey of local Tomato growing field of Tikamgarh , it was observed that most of the Tomato fruits have been suffered by fruit rot disease caused by Alternaria solani. The maximum incidence of fruit rot disease has been observed in ill drained and low lodging fields, where water lodging was common and soil moisture found to be high. It was also noticed that tomato fruits which developed near ground level and came in contact with soil, almost suffered from the disease. In the present study the development of fruit rot disease has been studied on three different types of fruits of various age, i.e., Green, Semi ripe and Ripe Tomato fruits. Among the three types of fruits, the green fruits found to be very less susceptible and have shown some resistant against pathogen  Alternaria solani. The semi ripe” fruits have been found to be most susceptive for the pathogen, where as maximum rotting has been recorded in semi ripe fruits. The ripe fruits has been found to be moderately susceptible.
