The paper is dealing with limitations of disadvantageous side-effects of plant protection product use and continuous restriction on the conditions of their use. This concept is more or less obvious to most people who have no direct contact with agricultural production. The paper proposal is to describe the systems of adjustable buffer zones of surface waters, as in many EU countries is already the common practice instead of the use of fixed buffer zones (surface waters, application of PPP in areas near urban settlements) in Slovenia regulated by the Plant Protection Products Act and the Waters Act, and their sub-law regulations. In the areas, where the adjustable buffer zones are already established, there are more positive than negative experiences present, such as on the segment of monitoring of environmental parameters and also on the area of monitoring of the economic performance of agricultural producers. The adopted system would eliminate currently present difficulties, which often discourage producers from further agriculture production, or even completely make the agricultural production impossible.

Modern fruit orchards are treated with pesticides 15 to 25 times per season. The high frequency of pesticide application represents one of the most serious pollution threats to the neighboring environment among various agricultural production systems. More accurate targeted spraying is possible by detecting of tree canopy with different sensors and appropriate electronics. Ultra sound signal used in modern spraying equipment is processed by a personal computer and fed in real-time to spraying nozzles which open and close in relation to the canopy structure. The evaluation in field experiments by detecting deposits on leaves and water sensitive papers (WSP) demonstrates decreasing of the amount of delivered spray. Thereby significant reduction of costs and environmental pollution by plant protection products is possible.
