Tropical Melhoramento e Genética (TMG) and PlantArcBio have entered into a new research and development partnership aiming to produce cotton varieties resistant to cotton boll weevil (Anthonomous grandis) using RNAi (ribonucleic acid interference) technology. Under this partnership, PlantArcBio will leverage its expertise in RNAi-based products together with TMG’s experience in genetic improvement and commercialisation of genetic solutions for cotton. The companies aim to develop and deliver an innovative biological solution as another tool to address the cotton boll weevil problem in Brazil and adjacent markets.
