    Notes: Abstract Seventy Frankia spp. strains (nodulating N2-fixing actinomycetes) were isolated from root nodules of Casuarina equisetifolia from different localities of Tamil Nadu state, India. From these, four strains (UMCe12, UMCe23, UMCe35, and UMce55) were selected. Their potential use as biological control agents for Rhizoctonia solani root rot disease of C. equisetifolia seedlings and their relative efficiency in nodule production were investigated. Between the two inoculum broadcast systems tested, seed-coating with Frankia spp. cell suspension was superior to the soil application of cells as sand-vermiculite-basal ammonium propionate inoculum. UMCe12 was the promising strain, offering the highest level of disease protection (81.1%) and nodule production (88.1%) in the R. solani-infested soil, followed by UMCe23 (60.3 and 65.5% of disease protection and nodule production, respectively), UMCe55 (53.5 and 58.2%), and UMCe35 (45.4 and 44.5%). Further, a significant positive correlation was observed between the dose of Frankia spp. and efficiency in both disease control and nodule production.

    Notes: Organotin(IV) Schiff base complexes of the type (L)SnR2 [where R=CH3, C6H5 or CH2CH2CO2 CH3], (LH)Sn(C6H5)3 and (L)SnCl(CH2CH2CO2 CH3) [where LH2=2-N-salicylideneimino-2-methyl-1-propanol, derived from the condensation of salicylaldehyde and 2-amino-2-methyl-1-propanol] have been prepared and characterized on the basis of their elemental analyses, IR, 1H, 13C and 119Sn NMR studies. In these mononuclear complexes the Schiff base acts either as a dianionic tridentate or as a monobasic bidentate moiety by coordinating through an alkoxy group, an azomethine nitrogen and a phenoxide ion to tin. Sulphur dioxide inserts in the tin-methyl/-phenyl bond in the above Schiff base complexes to give tin-O-sulphinates of formulae (L)RSn(SO2R) and (LH)(C6H5)2Sn(SO2C6H5).
