A Study On The Efficacy Of Bifidan And Ivory M 72 wp Fungicides on Early Blight Disease ( Alternaria solani Ell. and Mart ) Johnes and Grout In Tomato Crop ( Lycopersicon Esculentum Mill)

Abstract

This research was carried out for studying the possibility of controlling early blight disease in tomato. The variety chosen was Peto 86. Two fungicides were tested. These were : Bifidan and Ivory M 72 WP in season 2004 – 2005 in Shambat Agricultural Research Station field . The two fungicides were applied at three different doses (concentrations) , i.e proposed dose and + 25% . The results showed that the use of the two fungicides at the three different concentrations used resulted in variable reductions in the disease incidence and in the disease severity and in increasing the yield. When I applied the Bifidan fungicide was applied at the concentration of 0.375ml/L resulted in the highest yield of 1.2 Ton VI ‫‪the use of Ivory M 72 WPat the least dose resulted the highest‬‬ ‫. ‪percentage of healthy fruits‬‬ ‫‪The proposed does for Bifidan ( 0.5 ml/l ) proved to be‬‬ ‫‪efficient in combating disease incidence and proved to be efficient in‬‬ ‫.‪combating the disease severity‬‬
