The investigations of Viltis tomato variety were carried out at the greenhouse. Biological efficiency of biopesticides BioNature R2000 (a.i. 210 g/l azadirachta indika, 180 g/l Pinus resinosa) and Ricinus communis and Neem-Azal-T/S (a.i. 1% azadirachtin A) were studied. BioNature R2000 at the rate of 0,1% water spraying solution and Neem-Azal-T/S at the rate of 0,5% water spraying solution was effective against larvae of whiteflies in tomatoes. In 2003 the biological efficiency of two applications with BioNature to control Trialeurodes vaporiorum was from 52.52 to 87.47%. In 2004 the biological efficiency of two applications with BioNature to control Tetranychus urticae was from 61.04 to 80.45%. In 2003 the biological efficiency of two applications with Neem-Azal to control Trialeurodes vaporiorum was from 57.56 to 79.88%. The biological efficiency of two applications with Neem-Azal to control Trialeurodes vaporiorum was from 57.55 to 78.86%. Phytotoxicity influence of Neem-Azal-T/S and BioNature R2000 on plants were not found
