Isolation and identification of grapevine trunk diseases in Palestine and possible use of bacteria as biocontrol agents against the disease

The grapevine trunk disease (GTD) has been considered a real threat on grape production. This study aimed to identify the GTD causing agents in Palestinian orchards and evaluate efficacy of bacteria control under vitro conditions. Two fungal isolates; Fusarium solani isolate GR Neofusicoccum parvum GR3 were identified diagnosed using PCR BLASTn analysis. After that, five bacterial isolates tested for their against growth fungi. Pseudomonas fluorescence ORS3 PFL showed very strong inhibition zones (> 10 mm, ++++) both fungi other able inhibit but was less varied among bacteria. effect F. greater than that N. GR3. Up our knowledge, this first its kind Palestine identifies GTD. Further studies are needed test field
