      abstract = {The paper presents analysis of available data on  resistance risk and cost of chemical protection for  selected plant protection products containing old and new  active substances. Based on the results covering 38  products registered in Poland for protection against  different groups of pests it was found that: use of  products containing new active substances is subjected to  the lower risk of resistance than use of products  containing old active substances and in most of cases the  cost of chemical protection using new active substances are  higher and often significantly higher than for old active  substances.},
