| Abstract:
Kanesho Soil Treatment (KST), a new organisatorial structure of Agro-Kanesho Company and Mitsui and Co (Japan) has acquired worldwide business for the soil fumigant products Basamid and DD, and for Monam in a restricted number of countries, as well as products under development. Certis Europe and Certis USA were appointed as distributors for Western Europe and the United States respectively. Certis launched in its strategy the concept ‘Clean Start’. This concept envelopes the use of soil fumigants and other Certis portfolio disinfectants for materials/tools and greenhouse cleaning, in order to start crops in a ‘sanitized’ environment where IPM measures can be used for continued pest and disease control during growing. Certis also aims to provide local distributors, applicators and end users, with more extended services and to promote a pre-disinfestation soil biological analysis (pest and disease risk diagnosis) as well as post-disinfestation monitoring of residual MITC by the ‘chemical nose’ Innotec, a specific measuring apparatus, possibly replacing the time consuming cress seed phytotoxicity test. The recently developed multiplex (DNAMultiscan®) DNA-based technique (developed by Scientia Terrae of the De Ceuster group in collaboration with the KULeuven university) should allow to decide 24 hours after sampling about the product choice, dose and combination of fumigants. This quick screening system, allowing simultaneous detection and rough quantification of about 47 phytopathogenic and antagonistic fungi, as well as about 9 bacteria, is under its way to become installed in different laboratories with enough sample capacity in different countries to provide with pre- and post-disinfestation soil check. In order to check in a shorter time residual potential phytotoxicity of methyl isothiocyanate (MITC) after dazomet or metam-sodium soil fumigation, the Innotec apparatus developed by the Bonn University and HKR Sensorsysteme in Munich on behalf of BASF company, needs only 30 minutes to provide with a 5-10 ppm sensitivity for MITC measurement, which is far more sensitive and quicker than cress test. The same principle could apply for the design of a 1,3-dichloropropene ‘nose’. Certis/KST want to provide the applicators and growers with added value beyond the products and intend to (re)study other alternatives/techniques in soil fumigation. | |
