As many growers are now aware Suscon Green Soil Insecticide has been withdrawn from the market place with a new formulation scheduled to be available this April/May 2011. However, the approval has been delayed. Fargro, who will be marketing the new formulation of Suscon Green in the UK, commented;
That leaves some of the following options which are all available through Dejex Supplies:
Met52: A biopesticide based on a fungus which provides prolonged control of vine weevil larvae when incorporated into growing media.
Imidasect: Provides short term control of vine weevil larvae when incorporated into peat based media, but does not provide more than a few months control, therefore, generally unsuitable for nursery stock.
Intercept: Formulated for incorporation into growing media, the Intercept compound is readily absorbed by roots and translocated to aerial parts of the plant to give protection against pest attack. Among the pests that are controlled are whitefly, aphids, sciarid fly and vine weevil.
Exemptor: Is also formulated for incorporation into growing media. It is effective against aphids whitefly, leaf beetles and vine weevil. Exemptor can provide up to 1 year of vine weevil control.
Nematodes: A biological control applied by drenching the growing media in the autumn and spring.
