An aqueous suspension concentrate fungicidal formulation for application to plants comprising at least one triazolopyrimidine of formula (I) is disclosed, wherein R1 and R2 independently denote hydrogen or C1-C10-alkyl, C2-C10-alkenyl, C2-C10-alkynyl, or C4-C10-alkadienyl, C3-C10-cycloalkyl, phenyl, naphthyl, or 5-or 6-membered heterocyclyl, containing one to four nitrogen atoms or one to three nitrogen atoms and one sulfur or oxygen atom, or 5-or 6-membered heteroaryl, containing one to four nitrogen atoms or one to three nitrogen atoms and one sulfur or oxygen atom, or where R1 and R2 radicals may be unsubstituted or may carry one to three groups Ra, wherein Ra is cyano, nitro, hydroxyl, C1-C6-alkyl, C1-C6-halo- alkyl, C3-C6-cycloalkyl, C1-C6-alkoxy, C1-C6-haloalkoxy, C1-C6-alkylthio, C1-C6-alkylamino, di-C1-C6-alkylamino, C2-C6-alkenyl, C2-C6-alkenyloxy, C2-C6-alkynyl, C3-C6-alkynyloxy and C1-C4-alkylene- dioxy; or R1 and R2 together with the interjacent nitrogen atom represent a 5-or 6-membered heterocyclic ring, containing one to four nitrogen atoms or one to three nitrogen atoms and one sulfur or oxygen atom, which may be substituted by one to three Ra radicals; R3 represents halogen or C1-C6-alkyl or C1-C6-alkoxy ; n represents an integer from 0 to 5 ; and Hal represents halogen together with one or more adjuvants selected from a) non-ionic water-soluble mixed polyalkoxylated aliphatic alcohol surfactants which is a random or block oligomer of formula: H2n+1Cn-O-(CH2CH2O)x(CH2CH(CH3)O)yH wherein: n is an integer from 8 to 18; x is an integer from 3 to 10 ; y is an integer from 1 to 3; and b) non-ionic water soluble ethoxylated aliphatic alcohol surfactants, the adjuvant is present in an amount sufficient to provide a ratio of the compound of formula (I) to adjuvant at 100: 75 to 100: 100.000 in the applied formulation. Adjuvants selected from non/ionic water/soluble mixed polyalkoxy-lated aliphatic alcohol surfactants, non-ionic water soluble ethoxylated aliphatic alcohol surfactants, amine ethoxylates, and micronized polymeric waxes enhance the efficacy of fungicidal triazolopzrimidines of structural formula (I). They can be incorporated into formulations of the fungicidal compounds or be added to spray mixtures (tank mix) as separately formualted additives in order to improve the efficacy and spectrum of these fungicides. Also disclosed are fungicidal compositions of the triazolopzrimidines and adjuvants, as well as methods for their use in the control of photopathogenic fungi.
