Nematicidal Activities of Bacterial Volatiles fromPseudoduganella violaceinigra G5-3 and Novosphingobium pokkalii G8-2 against the Pine Wood Nematode Bursaphelenchus xylophilus
Naturally-occurring volatile compounds with nematicidal activities have significant economic importance in agriculture and forestry. We identified two Gram-negative bacteria Pseudoduganella violaceinigra G5-3 and Novosphingobium pokkalii G8-2 that produced volatile compounds with potent nematicidal...
