1.  Effects of the nematicide imicyafos on soil nematode community structure and damage to radish caused by Pratylenchus penetrans 
Journal of Nematology  2011;43(1):1-6.
The effects of the non-fumigant nematicide imicyafos on soil nematode community structure and damage to radish caused by Pratylenchus penetrans were evaluated in two field experiments in consecutive years (2007 and 2008). Nematode densities in soil at 0 - 10 cm (the depth of nematicide incorporation) and 10 - 30 cm were measured. The application of imicyafos had a significant impact on the density of P. penetrans at 0 - 10 cm but had no effect on free-living nematode density. PCR-DGGE analysis conducted using extracted nematodes showed that the nematode community structure 12 d after application in 2007 was altered by the application of imicyafos at the 0 - 10 cm depth, but not at 10 - 30 cm. No significant differences were observed in the diversity of the nematode community at harvest (89 and 91 d after application) between the control and imicyafos treatments in both depths and both years. In both years, the damage to radish caused by P. penetrans was markedly suppressed by the nematicide. Overall, the nematicide imicyafos decreased populations of P. penetrans in soil and thereby decreased damage to radish, while having little impact on the soil nematode community.

2.  (5,10,15,20-Tetra­phenyl­porphyrinato-κ4 N)(2,2,2-trifluoro-1-phenyl­ethyl­idene-κC 1)ruthenium(II): a stable fluorinated alkyl­idene complex of a ruthenium(II) porphyrin 
In the title compound, [Ru(C44H28N4)(C8H5F3)], the fluorin­ated alkyl­idene group is bound to a five-coordinate Ru atom, which is located toward the carbene C atom, 0.3301 (5)Å from the least-squares plane of the C20N4 porphyrin core. The Ru=C bond is tilted slightly from the normal to the C20N4 least-squares plane due to steric repulsion between the porphyrinate ligand and the bulky trifluoro­methyl group. The Ru=C bond length of 1.838 (2) Å is comparable with those in bis­(subsituted phen­yl)carbene analogs.
