Sands and Rovira in 1972 (9) were among the first to use a mutant form of Pseudomonas solanacearum as a biocontrol agent to control weeds. Since then, biocontrol of weeds has expanded using predominantly fungal pathogens. 

Phytuberin has also been found32 in tobacco leaves infiltrated with Pseudomonas Solanacearum. In addition phytuberin was isolated from Pseudomonas Solanacearum U-7. The methylene chloride extract from the callus contained phytuberin (55) and phytuberol (56). Both (55) and (56) were absent from healthy tissues. They were identified33 as stress compounds in leaves ofNocotianatabacum CV SamsunNN. sylvestris.

The antimicrobial activity of the crude extract of Parmelia perlata (Huds.) Ach. and its two constituents 64 and 65 (4-amino-3-hydroxy-6-methoxy-2-methylcyclohexa-l,3-diene-l-carbaldehyde and 5-amino-2-ethoxy-4-methyl-cyclohexa-l,3-diene-l-carboxylic acid, respectively) was reported by Thippeswamy and coworkers. Compound 64 was found to be significantly more active against Corynebacterium michiganensis, whereas compound 65 was active cLgcdnst Pseudomonas solanacearum [79].
