The reduction of crop yields caused by the effect of “tired soils” is a phenomenon well known to all farmers. The action of pathogenic fungi, insects and nematodes, as well as the accumulation of toxins generated by previous crops are some of the factors that most affect the gradual reduction of yields and the quality of successive harvests.  


RAISAN® K57 is a general soil disinfectant, based on Metam potassium, with fungicidal, insecticide, nematicide and herbicide activity.  


In a period of changes in soil disinfection, treatment with RAISAN® K57 is reaffirmed as a respectful and reliable disinfection without any ecotoxicological problems that allows to regenerate soil fertility and maintain or increase the yield and quality of crops.  


RAISAN® K57 is especially recommended in areas with salinity problems (soils and / or saline irrigation water) since not providing sodium can be used repeatedly in these conditions without aggravating the problem. In addition, it improves fertilization as it provides easily assimilated potassium. 


RAISAN® K57 is an organic synthetic product based on Metam potassium and formulated as a soluble concentrate. In aqueous dilution it decomposes into the active and volatile compound called methyl isothiocyanate (MIT) which, in the soil, diffuses in the form of gas.
