Delivery systems for efficacy improvement of volatile herbicides

Introduction: The development of biodegradable materials for crop delivery systems still remains a challenge. Clomazone is used in pre or postemergence aiming the control of weeds in several crops¹. This AI exhibits a considerable volatility². This work focuses on the development of a nanoemulsion for clomazone aiming the decrease of the AI volatilization. The system comprised an oil phase containing clomazone, resulting in a nanoemulsion containing more than 20% of AI. Formulation was submitted to stability studies as well as to a volatilization protocol for comparison with commercial product.
