The heterogeneity of sprout inhibitor application with chlorpropham.

The CIPC or chlorpropham is used on potatoes as "sprouting inhibitor". These lasts years, some set of belgian potatoes treated by CIPC exceeded the Maximum Residue Limit (MRL), fixed at 5 mg/kg. The heterogeneity of sprout inhibitor application would be one of the causes of over-dosage.

Rinsing and management of pesticides' containers.

In order to reduce the effects on the environment, it is necessary to improve the management of pesticides' containers. Usually, users burn or bury empty containers. These methods, even though decreasing must be avoided or even forbidden.

Comparative study of anti-drift nozzles' wear.

When spraying, the drift is a restricting factor which reduces the efficiency of pesticides treatments and increases their impact on the environment. The use of anti-drift nozzles is the most common technique to reduce the drift effect. The basic principle of all anti-drift nozzles is to produce bigger droplets (Imag DLO, 1999) being less sensitive to the wind.

Study of potatoes' sprout inhibitor treatments with chlorprophame.

Studies carried out in 1999 by the University of Ghent showed that 36% of potatoes' samples contained Chlorprophame (CIPC) residues and that 7.9% of them exceeded the maximal limit of residues (RML), fixed at 5 ppm. The heterogeneity of sprout inhibitor application would be one of the causes of over-dosage.
