The experimental temperature conditions were 40°C , 16°C and 5°C for soil and 15°C for green plants. The results which were evaluated by photocopying of the TLC spots on a graph paper and square counting showed that carbaryl degradation is a first order reaction and the temperature dependent half-life of the degradation takes grater than four weeks under the investigated conditions. Karbarilin Parçalanma Süresine Çevresel Sıcaklığının Etkisi Özet: Bu çalışmada, oldukça geniş bir spektrumda kullanılan Karbaril (Sevin) adlı ziraii mücadele ilacının toprakta ve yeşil yapraklı bitkiler üzerindeki parçalanma süresine sıcaklığın etkisi laboratuvarda kurulan modeller üzerinde incelenmiştir. Deneysel sıcaklık şartları toprak için 40°C, 16°C ve 5°C; yeşil yapraklı bitkiler için 15°C olarak seçilmiştir. İnce Tabaka Kromatografisinde karbarilin oluşturduğu lekelerin grafik kağıdına fotokopisi çekilmiş ve kare sayma metoduyla kantitatif değerlendirme yapılmıştır. Parçalanma reaksiyonunun birinci dereceden olduğu ve incelenen şartlar altında sıcaklığa bağlı parçalanma yarı ömrünün 4 haftadan daha uzun bir süre aldığı tesbit edilmiştir. Introduction Carbaryl (1-naphtyl methyl carbamate), was first synthesised by in 1953 and introduced as an agricultural insecticide in 1958. Since then it is one of the most widely used insecticides in the world against fruit, vegetable, cereals, timber forest, .
