Efficacy of Some Chemical Pesticides Against the South American Tomato Leaf Miner – Tuta absoluta
Downloads
The tomato leaf miner -Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a major pest of tomato culture. It is an invasive oligophagous insect and damages tomatoes both in the field and in greenhouses and storage conditions as well. It also damages other cultural representatives of the Solanaceae family (potato, eggplant, tobacco, goji, etc.) and wild species. T. absoluta was first discovered in Georgia in 2011, it quickly spread to all regions of the country due to its high reproductive capacity and became a major pest. T. absoluta spread and damaged plants both in greenhouses and in open field. In recent years, the rapid increase in the insect population has caused significant damage to tomatoes in Georgia. In general, 8-10 generations of T.absoluta can develop during the growing season in lowlands and greenhouses.
The aim of the presented work is to use various chemical pesticides against T. absoluta and determine their effectiveness. In 2023, in a small greenhouse farm in the village of Daba Agari, Kareli district, were tested the following preparations against the pest: Coragen, Belt, Brandon.
Initially, a number of pesticides were tested against T. absoluta larvae to determine their toxicity. Coragen (0.04 l/ha), Belt (40 ml/ha), Brandon ( 100 ml/100 l), the biological effectiveness of which was: Coragen - 87.5%, Belt - 82.2%, Brandon - 76%.
