  • Applications

    Methomyl is an insecticidal active ingredient used in agriculture to control a broad range of pests on crops such as vegetables, fruits, cereals, and ornamental plants; its typical applications include spraying or incorporating it into crop protection products in emulsifiable concentrate (EC) or granular form for use in field and greenhouse settings, and it is commonly employed as part of professional crop protection programs in commercial farming and nurseries, subject to local regulations and application limits.
