Fluensulfone, the active ingredient in Nimitz from ADAMA Agricultural Solutions, is a nematicide for the control of root-knot nematodes in cucurbits and fruiting vegetables, and the first new chemical nematicide to be developed in more than 20 years. It is categorized under a new class of chemistry and has a novel mode of action with favorable toxicological and eco-toxicological profiles. Nimitz data development for EPA focused on supporting a “Caution” claim, which addresses the current limitations on nematicides including: fumigant management plans, 24-hour field monitoring, buffer zones, and restrictive PPE requirements. At presstime, all data supporting Nimitz in the U.S. was pending EPA review. Visit Adama.com/us Photo by Gerald Holmes

Paladin, based on the active ingredient dimethyl disulfide, is Arkema’s broad-spectrum, pre-plant soil fumigant that is effective against weeds, soilborne plant pathogens, and nematodes. It is registered for use with vegetables (tomatoes, peppers, and eggplants), cucurbit crops (cucumber, squash, and melons), strawberries, blueberries, field-grown ornamentals, and forest nursery stock. Paladin can be used as a standalone fumigant, as a component in a sequential fumigation with metam sodium, or as a component in a fumigant cocktail of 79% Paladin + 21% chloropicrin. For optimal weed control, a topical herbicide should be used. Visit Arkema.com Photo by Gerald Holmes

Double Nickel 55, available from Certis USA, is an alternative to traditional soil fumigants that control bacterial and fungal pathogens. Applied at planting and with follow-up applications, Double Nickel is being used on potatoes to control Erwinia and Rhizoctonia, on melons to control common root rots, and on vegetables, such as peppers and onions, to control Phytophthora capsici and Pythium cavity spot. Double Nickel is based on Bacillus amyloliquefaciens strain D747 (Ba D747) and controls fungal and bacterial diseases using five modes of action. Visit CertisUSA.com

Isagro’s Dominus is a pre-plant soil biofumigant that controls a broad spectrum of soilborne fungi, nematodes, weeds, and insects. Dominus is the first biofumigant created for use in both conventional and in organic crop production. It was approved by EPA in September 2013 for conventional use, and addition to USDA’s National Organic Program’s list of approved substances for organic crop protection is anticipated as early as 2015. Dominus is registered for use on all crops including strawberries, tomatoes, peppers, cucurbits, and melons. Dominus does not require a fumigant management plan, has minimal buffer zone requirements, has a short planting interval of only 10 days, and leaves no residue in the soil prior to planting.
