Tomato is an important crop for the human race where they are regularly used in their food. Tomatoes are largely cultivated throughout the world. Many consequences arise throughout the cultivation. Diseases are more important among one of them. disease causes more damage to the entire crop in terms of yield reduction, early blight of tomato is an destructive diseases caused at an early stages of the plants which can cause the entire crop to die. In vitro studies shows that fungicides are very much effective in control of Alternaria solani which causes early blight in tomato. four fungicides were used to evaluate the inhibition efficacy on Alternaria solani and the results shown that a combination fungicide so called Tebuconazole10%+sulphur65% gave a high inhibition rate at lower concentrations i.e, 98% inhibition @250 ppm followed by propineb and mancozeb. The least inhibition rate is shown by carbendazim i.e 55% inhibition @1000ppm.
