INTRODUCTION: Calendula officinalis L. and Matricaria recutita L. are two medicinal species of a great economic and social significance in Cuba, its growing with yearly frequency has been affected by appearance of plagues and diseases deteriorating the plant mass performance and its quality. OBJECTIVES: to determine the biopesticides influence on quality parameters of Calendula officinalis L. and Matricaria recutita L. METHODS: the plant drugs underwent a botanical origin biopesticides treatment: (Melia azederach L. and Nicotiana tabacum L.) and of biological origin: (the mushrooms Beauveria bassiana, Verticillun lecanii and Trichoderma viridis with the bacteria Bacillus thuringiensis), taking into account the low costs and single methods to obtain its extracts without damage the environment. The quality parameters performed to inflorescence in both plant drugs after its drying at 38 ºC and grinding were: humidity, total ashes, soluble substances, essential oil and total flavonoids. RESULTS: it was proved that applications by biopesticides nebulization have not influence on total ashes, working in surface of floral inflorescence due to repellent property or poison-contact present in biopesticides used noting an increase in total flavonoids and in soluble substances in 70 % ethanol in the case of C. officinalis whereas M. recutita showed as favored the percentages of soluble substances in water and in essential oil as regards the controls. CONCLUSIONS: in these cultures the infestation economic threshold favoring the quality of drugs obtained.
