Abstract	It is very frequent in the agricultural practices to use treated seeds to assure a larger crop protection. The purpose of this research is to develop a quick method for monitoring batches of seeds. So the buyers could be informed on the products and the active matters coating these seeds and, especially, on the average concentration of these active matters and the homogeneity of the treatment on these batches. By way of its quick and non-destructive features, the Near Infrared Spectroscopy (SPIR) seems to be a relevant technique to face up to the three aspects of this problem. The methods and the established models will be transferred to other instruments which could be set in the laboratories of the Department of the Inspection of Raw Materials (3). The aim of this work is to establish equations to analyse the Tefluthrin, active matter (Insecticide, family of Pyrethroide) present at the rate of 40 g/l in Austral Plus, product applied to wheat seeds and to fight against the ground-insects, the birds and some viral diseases. The employed dose of Austral Plus is usually 500 ml for 100 kg of seeds. Until now, 98 batches of wheat seeds were used to build the calibration to estimate the average concentration, and 630 seeds within 42 batches for the calibration to control the homogeneity in the batches. The models developed on ninety-eight batches give good calibrations and the other models to control the homogeneity of the treatment are studied and seem to give interesting results. We can already affirm that the NIR technique is relevant to predict this active matter on batches of seeds. In the future, that would be interesting to build models for others active matters and thus other important products used for coating other seeds.
