Intensive apple protection against scab carries with the risk of resistance of fungus Venturia inaequalis on fungicides. Literature data indicates that high risk of resistance occurrence create substances belonging to benzimidazoles, dodine, strobilurins and anilino-pyrimidines. Currently, there are 62 fungicides (24 active substances) placed on the Polish market, applied in the protection of apple against scab. Active substances represent 6 different modes of action. There are no products containing benzimidazoles among currently available fungicides to control scab. Diversity of fungicides as we take into account mode of action allow to rotation of preparations and resistance prevention by this way. In recent years products containing new active substance with different mode of action than previously used were registered, which additionally improves the possibility of rotation of preparations. The presence of two active substances with various modes of action in a few fungicides is an additional, important element of resistance prevention strategy. According to the obligation of the integrated plant protection observance of the rules of anti-resistance strategy is very important.

The crops used as a source of renewable energy, like all the other crops can be damaged by harmful organisms and diseases and may require chemical protection. The analysis of the register of plant protection products placed on the Polish market on 21.07.2014 shows significant differences in their availability. For crops grown in Poland on large areas, such as oilseed rape and maize, numerous products are available and the chemical protection possibilities are in principle sufficient. For minor crops, especially those grown mainly or solely as energetic crops, the protection possibilities are either very limited or non-existent.

The cost of apple protection against fruit-tree red spider mite (Metatetranychus ulmi) and codling moth (Laspeyresia pomonella) was analyzed. The plant protection products containing active substances of natural and chemical origin were listed and compared. The analysis of protection costs considering 15 products failed to confirm the thesis that the protection with the use of chemical substances is cheaper than using the substances of natural origin. The products containing substances of natural origin do not ensure protection against all economically important insects and their availability is worse in comparison to chemical products.

The plant protection in allotments and home gardens is not without significance. The amateurs willingly use the possibilities of chemical protection against harmful organisms as evidenced by data concerning the consumption of plant protection products by unprofessional users. Currently, 69 preparations are available for the amateurs of which 23 products are used in the protection of nightshade plants including 14 fungicides, 6 insecticides and 3 herbicides. The number of registered preparations is small. The possibilities of protection against many significant pests are limited and in many cases there is no possibility of chemical protection. Lack or very limited possibilities of active substances rotations contribute to the development of resistance. Harmful organisms which are resistant in allotments or home gardens may be transmitted and contribute to the further development of resistance and consequently may cause economic losses in commercial crops.

Carbendazim, available on the Polish market since 1976, is one of the oldest substances used in the protection of cereals and oilseed rape. According to Regulation 542/2011, the substance will be withdrawn from use in plant protection. As a consequence, from June 2016 a part of cheaper preparations used in the protection of cereals and oilseed rape against fungal diseases will be no longer available. Products with carbendazim are currently the only registered solution for spring oilseed rape seed treatment.
