Pesticidal mixtures of dihydropyridazinones and pyridazinones with other fungicides and pesticides are disclosed. Fungicidal compounds are often applied in conjunction with one or more other fungicides to control a wider variety of undesirable diseases and with other pesticides in order to control numerous pests within the same application. Typical pesticides include insecticides, nematocides, miticides, arthropodicides, bactericides or combinations thereof.

Fungicidal Mixtures

U.S. 5,552,409 discloses dihydropyridazinones and pyridazinones of the formula

wherein A is –(CHR2)n-CHR7-Z-; -CF2-CF2-Z-; -(CHR2)n-O-Z-;-(CHR2)n-S-Z-; -O-CHR7-Z; -CR2=CR7-Z; -CR2=N-Z-; -CHR2-CR7=Y-; or –CR2=CR2-Y=; D is CR8 or N; Q is an aromatic group such as optionally substituted phenyl, naphthyl, pyridyl, quinolinyl, thienyl, furanyl, benzothiophenyl, benzyl, benzopyrimidinyl, benzopyridinyl, benzodioxolyl and the like as describe in U.S. 5,552,409; Z is carbonyl or thiocarbonyl; Y is carbon substituted by halo, alkoxy, alkynylthio or triazolyl; wherein R1 is alkyl, hydroxalkyl, cyanoalky, hydrazidal, cycloalkylalkyl, heterocyclylalkyl, phenyl, phenylalkyl, phenylcarbonyl, alkenyl, haloalkenyl, pehnylalkenyl, alynylalkenyl, and the like; R2 and R8 are independently H, alkyl, phenyl, cyano or halogen; R7 is H, alkyl, phenyl, cyano or halogen alkynyl, alkynylalkenyl, dialkynyl, haloalkynyl, and alkenylalkynyl; R3 and R6 are independently H, alkoxy or halogen,; R4 is H, halogen, alk9xy or nitro; R5 is H, halogen, nitro, alkyl, alkoxy, alkylthio, haloalkyl, haloalkoxy, haloalkylthio, phenyl, phenoxy or cyano; or R2 and R3 together for a alkyl, alkylene or carbonyl link; or R2 and R7 together form a fused phenyl or cycloalkyl ring;  X is oxygen or sulfur and n is 0, 1 or 2; and agronomically acceptable enantiomorphs, acid addition salts and metal complexes thereof; and their usefulness as a fungicide.

Ddihydropyridazinones and pyridazinones can also be combined with other fungicides to form fungicidal mixtures and synergistic mixtures thereof.  Fungicidal compounds are often applied in conjunction with one or more other fungicides to control a wider variety of undesirable diseases. When used in conjunction with other fungicide(s), dihydropyridazinones and pyridazinones can be formulated with the other fungicide(s), tank mixed with the other fungicide(s) or applied sequentially with the other fungicide(s).  Such other fungicides include enestrobin, antimycin, quinoxyfen, SYP-048, IK-1140, NC-224, 2-(thiocyanatomethylthio)-benzothiazole, 2-phenylphenol, 8-hydroxyquinoline sulfate, Ampelomyces quisqualis, azaconazole, azoxystrobin, Bacillus subtilis, benalaxyl, benomyl, benthiavalicarb-isopropyl, benzylaminobenzene-sulfonate (BABS) salt, bicarbonates, biphenyl, bismerthiazol, bitertanol, blasticidin-S, borax, Bordeaux mixture, boscalid, bromuconazole, bupirimate, calcium polysulfide, captafol, captan, carbendazim, carboxin, carpropamid, carvone, chinomethionate, chloroneb, chlorothalonil, chlozolinate, Coniothyrium minitans, copper hydroxide, copper octanoate, copper oxychloride, copper sulfate, copper sulfate (tribasic), cuprous oxide, cyazofamid, cyflufenamid, cymoxanil, cyproconazole, cyprodinil, dazomet, debacarb, diammonium ethylenebis-(dithiocarbamate), dichlofluanid, dichlorophen, diclocymet, diclomezine, dichloran, diethofencarb, difenoconazole, difenzoquat ion, diflumetorim, dimethomorph, dimoxystrobin, dinico...
