Crops are not planted until all fumigant has dissipated from the soil. With moisture, methyl isothiocyanate gas is released, which kills most scarified seeds and fleshy vegetative parts including rhizomes and germinating seedlings. Application Methods Apply uniformly using injectors, water or other incorporation tools to carry the product to the desired soil depth. May be applied via the irrigation system. Residual Activity 10 to 40 days depending on soil temperature and the amount of organic matter present in the soil.
Persistence is greatest at low temperatures and high levels of organic matter.
Planting may take place 12 to 16 days after the treatment and following a lettuce-seedling bioassay that indicates no injury. Unique Characteristics Also controls nematodes, soil fungi and soil insects. All traces of toxic gases must be dissipated from the treated soil before planting or plant injury may occur.
