ABSTRACT- The present investigation on the impact of fungicides on the growth and development of Spodoptera litura was carried out in the laboratory of the Department of Entomology, SKUAST- Jammu, during the year 2012-13. Base-line toxicity of two fungicides viz., mancozeb and ridomil MZ were evaluated against S. litura in the laboratory. The results showed that fungicides significantly influenced the growth and development of S. litura. The larval development duration was significantly short, and it was an average (14.61± 0.30), (16.28±0.66) days, when treated with ridomil, and mancozeb respectively. The results show that fungicides can serve a practical tool to reduce the S.litura and may assume a greater role in integrated programs showed to manage insect pests and pathogens.
