Because of the high solubility, tricyclohexyl-tin benzoate can be easily formulated in the form of an emulsifiable concentrate.

Abstract: Provided is a method of obtaining endomycorrhizian fungi with vesicles and arbuscules in vitro. The method comprises producing dicotyledone roots which have been genetically converted by inserting genes of root inducing or tumor inducing plasmid into the genome of dicotyledone roots, and then inoculating the converted roots with endomycorrhiza spores. Application of the present method can be very useful in agriculture and horticulture.
