Fusarium Chlamydosporum

The objective of this study was to evaluation the efficiency of  Arbuscular mycorrhizal fungi and some species of  Plant growth promoting rhizobacteria (PGPR) to control Fusarium chlamydosporum fungus causing agent of decline date palm off-shoots. The isolation and identification results  showed presence of F. chlamydosporum fungus from infected roots of infected palm trees and its major causing agent of diseases. The results  appeared  Pseudomonas fluorescens , Azotobacter chroococcum and Azosperillium sp. have high antagonism of pathogen under laboratory conditions. The evaluation results of  biocontrol factors Glomus  intraradices, G. mosseae, Gigaspora,  P. fluorescens, A. chroococcum and Azospirillum sp.  indicated that all treatments caused significant reduction in disease  severity of death palm off-shoots disease into13.3-60.0%. compared to control (pathogen only) 86.7%. The interaction between G. intraradices and  P. flourescens  caused significant reduction in disease severity to 13.3% and enhanced the growth of foliage and root of offshoots length to 39.0 and 36.3cm respectively and increased the fresh and dry weight of  foliage and root, 1.7750, 0.4977, 1.764 and  0.339g  this result was closed to Beltanol fungicide effect. Also all biocontrol agents which used in this study alone (without pathogen) enhancement of plant growth  compared with control treatment. The results of the current study showed for the first time that Arbuscular mycorrhizal fungi and Azospirillum sp. Bactrium to control and have good inhibition of Fusarium chlamydosporum fungus causing agent of decline date palm off-shoots and increasing plant growth in Iraq.

Mikroba Bacillus subtilis merupakan agen pengendali hayati mempunyai kelebihan sebagai Plant Growth Promoting Rhizobacteria (PGPR) yaitu dapat berfungsi sebagai biofertilizer, biostimulan, biodekomposer dan bioprotektan. Tujuan penelitian mengetahui potensi B. subtilis dalam merombak bahan organik sebagai usaha meningkatkan ketersediaan bahan organik tanah yang semakin menurun. Penelitian menggunakan Rancangan Petak Terbagi dengan berbagai  bahan organik sebagai petak utama (B0 = tanpa bahan organik, B1 = kotoran ayam,  B2 = kotoran kambing, B3 = kotoran sapi) dan aplikasi B.subtilis sebagai anak petak (A0 = 0 cc/L, A1 = 5cc/L, A2 = 10 cc/L, Pengamatan meliputi variabel tinggi tanaman, indeks luas daun, jumlah buah per tanaman, berat buah per tanaman, dan bahan organik tanah. Data pengamatan  dianalisis ragam  menggunakan  Statistical Product and Service Solutions (SPSS) versi 25 dan dilanjutkan dengan uji Duncan untuk mengetahui signifikansi perbedaan antar perlakuan. Hasil penelitian menunjukkan tidak terdapat interaksi antara bahan organik kotoran ternak dan konsentrasi B. subtilis terhadap semua variabel pengamatan. Potensi B. subtilis sangat baik dalam mendekomposisi bahan organik yang ditunjukkan dengan peningkatan bahan organik, dan hasil terbaik pada kotoran  sapi (B3) dan konsentrasi B. subtilis 15 mL/L masing-masing sebesar 46.47 % dan 34.76 %. Variabel pertumbuhan tidak berbeda nyata kecuali tinggi tanaman dengan pertambahan tinggi paling banyak pada pemberian kotoran kambing sebesar 170.69 %.
