Emulsion stability and residue evaluation of natural fungicide from neem and eugenol oil in 300 EC formulation
Abstract
Nowadays, natural fungicide is developed to replace synthetic fungicide which has shown harm to environment and human. Natural fungicide is considered safer for environment because it is easy to decompose and less toxic. The potential natural resources that can be used as fungicide are neem and eugenol oil. Neem contains bioactive compound azadirachtin that can act as repellents, pest management and broad spectrum fungicide. Eugenol is derived from clove and often used as mosquito repellent, bactericide and fungicide. Neem and eugenol oil is formulated in Emulsion Concentrate (EC) to enhance its dispersion in water to make it more effective as fungicide. This study investigates the fungicide emulsion stability and its residue in water and soil. The result showed that the best EC formulation with 30% oil, 60% solvent and 10% surfactant with non-ionic: anionic surfactant ratio 4:6. The residue evaluation also showed that the use of this fungicide is safe for water stream with average pH 6.88, TDS value 218.2 mg/l and TSS value 2.98 mg/l. Soil residue analysis by GCMS showed that neem and eugenol oil derivatives still remained on soil for five days.
