Abstract
In the aim of the current research to investigate the effect of three different commercially locally available fungicides were tested both in vitro and in vivo against Rhizoctonia bataticola chickpea to root rot under the natural field conditions. Three commercially available fungicides were Bavistin ®, Aliette ®, and Biomagic ® at the rate of 2g/L was tested in vitro. After 16 days of incubation the minimum colony diameter was recorded (7.9 mm) when applied the Bavistin ®, Aliette ® (20.2 mm) and Biomagic ® (27.1mm) as compared to control (63.0 mm). In vivo experiment were used same fungicides and four different varieties to control dry root rot and their impact on yield were evaluated at the rate of 4g /L against R. bataticola while varieties used were Karak-1, Karak-2, Karak-3, and Sheenghar. Disease severity was recorded lowest (19%) and highest yield (1467 kg/ha), plant height (47.5cm), number of pods/plant (15.0) and number of grain/pods (1.66) were recorded in cultivar Karak-1. Among the fungicides, the Bavistin ®, was found to be the most effective fungicide resulting in the lowest disease severity (5%) and kg/ha), highest plant height (64.1cm), highest grain yield (1488), number of pods/plant (24.5) and number of grain/pods (2.25). It is concluded that the integrated use of Karak-1 and Bavistin ®, fungicide drugs gave promising results for controlling dry root rot of chickpea, and increased plant height, number of pods/plant and number of grain/pods.
