Liquid concentrated fungicidal composition and method for inhibiting the growth of phytopathogenic fungi in the locus

 

Describes liquid concentrated fungicidal composition comprising fungicide-acceptable carrier and/or surface-active agent and synergistically effective amounts of (a) one morpholide acrylic acid of the formula (I)where R1and R2each independently is a hydrogen atom or halogen, (b) and one fungicide derived N-pyridylamino formula (II)where R3and R4each independently is a halogen atom or halogenation, Y each independently represented by a halogen atom or optionally substituted alkyl group, m=2. Especially preferred compound of formula (I) is dimethomorph, and the compound of the formula (II) - fluazinam. Describes a method of suppressing the growth of phytopathogenic fungi in the locus which comprises applying to the locus of the above-mentioned composition. The technical result is to obtain compositions that are effective against diseases caused by oomycetes, such as Phytophtora infestans. 2 C. and 7 C.p. f-crystals, 2 tab.
