This study was conducted in the labs. of Date palm research center- Basrah University, from ( 1. 3 . 2009 – 1 . 10 . 2009 ) Isolation of five species of fungi from the shoot tip of three cultivars of date palm ( Braim, Hillawi and Sayer) were carried out , wich are Aspergillus niger, Fusarium sp. Penicillium sp ., Alternaria alternata ., and Rhizopus sp. ,
Also Isolation and of seven species of fungi that contaminate the callus tissue cultures of three cultivars of date palm ( Braim, Hillawi and Sayer) were carried out, wich are A. alternata, Penicillium sp., A. niger , A.clavatus, Ulocclodium atrum , Rhizopus sp. and Stemphylium sp., Also the study showes that the fungi A. niger و Rhizopus sp و A. alternata و and Penicillium sp . are the same before and after invitro culture .
Evalution of three fungicide agenst the fungi isolated from the shoot tip revealed that Mancozab the most effective fungicide that give inhibited percentage 92.7 % compare white the other fungicide Switch and Ridomal gold M 272 , witch give inhibited percentage % 82 and % 54.6 . |
