An alternative to synthetic insecticides is the use of naturally occurring products, such as botanical products with insecticidal properties. Biological testing of the botanical products Krisant EC 750 ml/ha and Neem Azal T/S 0.3% was performed at the Maritza Vegetable Crops Research Institute - Plovdiv to determine their effectiveness against potato aphid (Macrosiphum euphorbiae Thomas, 1878), thrips (Thrips tabaci Lindemanla, 1889; Frankliniella occidentalis Pergande, 1895), greenhouse whitefly (Trialeurodes vaporariorum Westwood, 1856), cotton bollworm (Helicoverpa armigera Hübner, 1808), tomato leaf miner (Tuta absoluta Meyrick, 1917) and two-spotted spider mite (Tetranychus urticae Koch, 1836). These species are some of the most common economically important pests in growing tomatoes in greenhouses. The phytopesticides Neem Azal T/S and Krisant EC were applied alone and in combination. The tested plant protection products showed very good biological activity against these pests and relatively higher effectiveness over 78% shows the combined treatment. [ABSTRACT FROM AUTHOR] |
