A method of controlling Take-all disease of plants by applying, preferably to the seed prior to planting, a fungicide of formula (1), wherein Z1 and Z2 are C or N and are part of an aromatic ring selected from benzene, pyridine, thiophene, furan, pyrrole, pyrazole, thiazole, and isothiazole; A is selected from -C(X)-amine, -C(O)-SR3, -NH-C(X)R4, and -C(=NR3)-XR7; B is -W m-Q(R2)3 or selected from o-tolyl, 1-naphthyl, 2-naphthyl, and 9-phenanthryl, each optionally substituted with halogen or R4; Q is C, Si, Ge, or Sn; W is -C(R3)p H(2-p)-; or when Q is C, W is selected from -C(R3)p H(2-p)-, -N(R3)m H(l-m)-, -S(O)p, and -O-; X is O or S; n is 0, 1, 2, or 3; m is 0 or 1;p is 0, 1, or 2.

Procédé servant à lutter contre le piétin-échaudage des céréales par l'application à la semence, de préférence, avant la plantation, d'un fongicide représenté par la formule (I), dans laquelle Z1 et Z2 représentent C ou N et font partie d'un cycle aromatique sélectionné à partir de benzène, pyridine, thiophène, furane, pyrrole, pyrazole, thiazole et isothiazole; A est sélectionné à partir de -C(X)-amine, -C(O)-SR3, -NH-C-(X)R4 et -C(=NR3)-XR7; B représente -Wm-Q(R2)3 ou est sélectionné à partir de o-tolyle, 1-naphtyle, 2-naphtyle et 9-phénanthryle, chacun est éventuellement substitué par halogène ou R4; Q représente C, Si, Ge, ou Sn; W représente -C(R3)pH(2-p)-; ou quand Q représente C, W est sélectionné parmi -C(R3)pH(2-p)-, -N(R3)mH(1-m)-, -S(O)p-, et -O-; X représente O ou S; n représente 0, 1, 2 ou 3; m représente 0 ou 1; p représente 0, 1 ou 2.
