CHEMICAL CONTROL OF COWPEA DAMPING OFF AND ROOT ROT

Abstract

Isolation result showed the presence of Fusarium solani ,Rhizoctonia solani ,Microphomina phasseolina and that fungicide Beltanol inhibited the growth ray of the three isolated fungi with different percentages , Somy-8 fully inhibited the growth ray of Microphomina phasseolina fall 100٪ and Benomyl inhibited the growth ray of F.solani with 82.64% . In green house experiment chemical control with Benomyl, Somy-8 and Beltanol caused significant decrease in diseases incidence , Somy-8 recorded 6.67 while Beltanol and Benomyl recorded 40%for both of them The fungicides lower disease severity for F.solani 0.29 ,0.25 and 0.24 respectively in addition to that there was improvement in growth parameters ,treatment with Benomyl caused significant increase in shoot length 21.63 cm while significant and Somy-8 caused significant increae in root length 17.53 and 17.87 cm respectively . Beltanol caused significant increasing in plant dry weight 1.79 g in addition to S/R ratio 10:49 which did not differ significantly with Benomyl and Somy-8
