    Patent number: 4461764
    Abstract: Compounds of the formula: ##STR1## wherein X is sulfur or oxygen; R.sub.1 is lower alkyl; R.sub.2 is lower alkyl, lower straight chain alkoxy, lower alkylthio, phenyl or the group --NR.sub.3 R.sub.4 where R.sub.3 and R.sub.4 are independently hydrogen or lower alkyl, provided that when X is oxygen, R.sub.2 is not phenyl, are pesticidal, exhibiting activity against pests such as plant fungal diseases and, in many cases, insects.

  • Algicidal and fungicidal 1-halo-2-substituted-thioethyl sulfones, 2-substituted-thiovinyl sulfones, and 1,2-dihalothioethyl sulfones
    Patent number: 4321080
    Abstract: 1-Halo-2-alkylthioethyl and 1-halo-2-arylthioethyl sulfones, having algicidal and fungicidal activity, are prepared by the addition of arylsulfenyl or alkylsulfenyl halides to alkyl or aryl vinyl sulfones. The thioethyl sulfone products are treated with a base to produce 2-alkylthiovinyl or 2-arylthiovinyl sulfones, which also have algicidal and fungicidal activity. The vinyl sulfones are halogenated to produce 1,2-dihalothioethyl sulfones, which have superior fungicidal activity, especially for tomato and celery late blight.
