Technology offer : Biopesticide based on essential oil of West Indian bay tree to control bacterial wilt in Solanaceae crops

Technology's description

Ranked as the second most important phytopathogenic bacteria worldwide, the agent Ralstonia solanacearum causes potato brown rot and bacteria wilt in solanaceous crops and cucurbit crops.

The agent R. solanacearum is the first pest in vegetables crops in Martinique. The phytosanitary situation is further compounded by the emergence of an ecotype of R. solanacearum (PhylIIB/seq4NPB), which is able to break the resistance of the commercial varieties. Bacteria wilt may cause up to 100% of tomato crop losses.

Without conventional treatment, fighting bacteria wilt is limited to prophylactic measures, which are inefficient under favorable conditions for the disease development. Pimenta Racemosa is an endemic plant to the Antilles, also known as West Indian bay tree or St Thomas Bay. The application of essential oil of Pimenta racemosa var. racemosa on the soil helps to control bacteria wild and to stimulate growth in tomato crops.

The development of a biopesticide based on essential oil of Pimenta racemosa meets the growing demand for sustainable and eco-friendly agriculture.
