Polymorphism and versatile solvate formation of thiophanate-methyl
2009
The polymorphism of a fungicide, thiophanate-methyl (TM), was investigated with conventional solvent screening methods. Two polymorphs, the thermodynamically most stable form I and the less stable form II, were found. TM was also found to crystallize as a plethora of different solvates which produced mostly form II upon desolvation. The structures of form I and form II and the fourteen discovered solvates were solved by single crystal X-ray diffraction. The most stable forms were further characterized by powder diffraction, thermoanalytical (TG/DTA, DSC and thermomicroscopy) and spectroscopic (IR, Raman, ¹³C CP/MAS NMR) methods. peerReviewed
Rhizoctonia solani AG5 and Its Offspring – Morphology and Sensitivity to Fungicides
2022
The objective of these studies was to identify differences and similarities within the progeny of Rhizoctonia solani AG5, which arose from basidiospores produced by the maternal strain ID23. The following characteristics were analyzed: appearance of the mycelium (color, structure, zonation, and presence of sclerotia), growth rate (at 10°C, 20°C, and 30°C), fungicide sensitivity, and hyphal structure. The mycelial color of R. solani AG5 ranged from white/cream to light and dark brown. The structure of the mycelium may be compacted or flattened with visible zoning or fluffy with dark brown sclerotia on the colony surface. Homokaryons and heterokaryons derived from homokaryons were analyzed by…
