چکیده
A study was conducted to evaluate the effectiveness of three selected botanicals namely leaf extract of Neem (Azadirachta indica), Debdaru (Polyalthia longifolia) and datura (black) (Datura metel) along with Bavistin (Carbendazim) and BAU-biofungicide (Trichoderma harzianum) against leaf spot disease (tikka) of groundnut caused by Cercospora arachidicola and Cercosporidium personatum at the Field Research Farm of Bangladesh Agricultural University, Mymensingh during 2009-10. The most effective treatments were Bavistin, BAU-biofungicide (seed treatment + spray), BAUbiofungicide (spray) and leaf extract of Neem. Bavistin increased pod and dry haulm yield by 53.51 and 24-80 %, respectively. Maximum pod yield and dry haulm weight were recorded under Bavistin. BAU-biofungicide (seed treatment + spray) produced the second highest pod and dry haulm yield followed by leaf extract of Neem and BAU-biofungicide (spray). BAU-biofungicide (seed treatment + spray) and leaf extract of Neem may be recommended for controlling leaf spot disease of groundnut.

A study was undertaken to evaluate effectiveness of foliar spray with 33 plant extracts against leaf spot (Tikka) of groundnut caused by Cercospora arachidicola and Cercosporidium personatum. Bavistin and BAU-Biofungicide were included in the experiment as checks and spray of plain water represented control. Almost all treatments gave considerable reduction in disease incidence and increase in ...

In West and Central Africa, three foliar diseases—early leaf spot caused by Cercospora arachidicola S. Hori; late leaf spot caused by Cercosporidium personatum Berk. & M.A. Curtis (syn. Phaeoisariopsis personata (Berk. & M.A. Curtis) Arx); and rust caused by Puccinia arachidis Speg.— are major constraints to peanut production. Disease distribution and severity vary from region to region with yi...
متن کاملIdentification of Transcripts Involved in Resistance Responses to Leaf Spot Disease Caused by Cercosporidium personatum in Peanut (Arachis hypogaea).
ABSTRACT Late leaf spot disease caused by Cercosporidium personatum is one of the most destructive foliar diseases of peanut (Arachis hypogaea) worldwide. The objective of this research was to identify resistance genes in response to leaf spot disease using microarray and real-time polymerase chain reaction (PCR). To identify transcripts involved in disease resistance, we studied the gene expre...
