COMPOSITIONS AND METHODS TO MODULATE RATE OF EBIS PRODUCTION FROM DITHIOCARBAMATE FUNGICIDES Russian patent published in 2018 - IPC A01N59/04 A01N47/40 

FIELD: biocides.

SUBSTANCE: inventions relate to methods and compositions suitable for combating plant fungal pathogens. Fungicidal composition for modulating the conversion of an ethylene bis-dithiocarbamate (EBDC) fungicide to ethylene bis-isothiocyanate sulphide (EBIS), which is: an EBDC fungicide, wherein the EBDC fungicide is mancozeb and the EBDC fungicide concentration is about 91.8 wt% or more of the total weight of the fungicidal composition, an EBIS formation modulating polymer, wherein the EBIS formation modulating polymer is polyvinyl alcohol, and the concentration of the EBIS formation modulating polymer is about 2 wt% or more based on the total weight of the fungicidal composition, and a dispersant, and wherein the EBDC fungicide is coated with an EBIS formation modulating polymer such that the half-life of EBIS release is increased by at least about half compared to the uncoated EBDC fungicide. Aggregated solid particle. Method of treating a plant.

EFFECT: inventions make it possible to reduce the applied dose of mancozeb necessary for eliminating fungi, to increase the interval between spraying, to minimise the decomposition by-product, id est, ethylene thiourea (ETU).
