Novel fungicidal properties of metabolites, culture broth, stilbene derivatives and indole derivatives produced by the bacteria (xenorhabdus) and (photorhabdus) spp.

摘要

The present invention relates to the use of microbes of the genera Xenorhabdus and Photorhabdus and the refined or raw metabolites of same from culture media for use as a fungicide for agricultural, horticultural, veterinary or human use. The present invention further relates to the use of dihydroxyalkyl-substituted stilbene derivatives of the formula: 3,5-dihydroxy-4-R-trans-stilbene; where R is an alkyl group of carbon length 1 to 6 with either a straight chain or branched configuration, such as 3,5-dihydroxy-4-isopropyl-trans-stilbene or 3,5-dihydroxy-4-ethyl-trans-stilbene, as fungicides which have protectant, preventative and eradicant capabilities. The invention also relates to the use of 3-substituted indole derivatives of the formulas: 3-(2'-acetoxy-4'-methyl-3'-oxohexyl)-indole, 3-(2'-acetoxy-4'-methyl-3'-oxopentyl)-indole, 3-(2'-hydroxy-4'-methyl-3'-oxohexyl)-indole, and 3-(2'-hydroxy-4-methyl-3'-oxopentyl)-indole and their stereoisomer as fungicides which have protectant, preventative and eradicant capabilities.
