Guideline for analysis

Since it has been found that benzoxazinoid allelochemical compounds and their decomposition products play an important role in the resistance of plant to insect pests and plant pathogenic fungi it has increased scientific interest for allelopathy meaning a potential for selective biological weed management.

Analytical methodology have been developed and validated to quantify the content of hydroxamic acids, lactams, benzoxazinones in wheat cultivars in different (organic and conventional) farming systems and benzoxazinone derivatives as aminophenoxazinones and corresponding malonamic acids in surrounding soils. Accurate methodology was achieved by an inter-laboratory study, which involved the laboratories, which carried out benzoxazinone analyses.

The results obtained from the project FATEALLCHEM will be very useful to implement the use of such chemicals in agriculture instead of pesticides. In this respect Directive 91/414/EEC concerns the placing on the market of plant protection products and the revision of this directive, specially concerning the zonal authorisation of pesticides will complicate the necessary risk assessment. By using alternative and more friendly compounds, like allelochemicals, it is expected that many of the problems encountered with the use of traditional pesticides will be solved and it will be easier to comply with Directive 91/414/EEC.
