Technologies to mitigate the effects of HLB using management strategies: nursery tree types, intercropping, scion/rootstock combinations and genetic tolerance This project aims at the development of phytotechnical processes and citrus varieties to contribute to the management of HLB based on experiments installed at the FCC in an area where HLB occurs. Several scion/rootstock combinations and five citrus seedling planting systems and intercropping with other species will be selected for production, in addition to the occurrence of Diaphorina citri and the incidence of HLB. Status: In progress Start date: Thu Apr 01 00:00:00 GMT-03:00 2021
HLB BioMath phase 3: biomathematics applied to the optimization of barriers interposition technologies, microenvironmental modification and exclusion for citrus huanglongbing management Citrus HLB is the most important citrus disease worldwide. It is considered a quarantine pest present in Brazil and threatens to spread throughout the national territory. The project helps to stem the spread of the disease in the country. It is structured to generate three Solutions for Innovation derived from the HLB dissemination scenarios and three specific problems:Absence of validated contingency plans for the decision to contain HLB in citrus groves in the Northeast; Phytosanitary alert in Status: Completed Start date: Wed May 01 00:00:00 GMT-03:00 2019
Feasibility of the use of Bacillus thuringiensis (Bt) for the reduction of Diaphorina citri population and improved citrus huanglongbing (HLB) management In the matter of control of HLB, the subject of study by several research groups has been the use of biological agents: predators, parasitoids or pathogenic microorganisms that are capable of decreasing the population densities of Diaphorina citri not only in areas where HLB is already established, but also in undersized areas where the high psyllid populations have not yet been subjected to such intensive spraying of pesticides. This project has contributed to the prospecting and characterizati Status: Completed Start date: Tue Jan 01 00:00:00 GMT-03:00 2019
Creation and selection of citrus varieties by classical and biotechnological procedures, with emphasis on the control of huanglongbing (HLB) and drought tolerance - Phase 2 The sustainability of Brazilian citrus is compromised by risk factors identified by the Citrus Technical Team of Embrapa Cassava and Fruits, according to their strategic action plan, 2017-2021. Two problems were more relevant: 1. Advance of huanglongbing (HLB, ex-greening) in the country, the most severe phytosanitary challenge of the world's citrus industry (BOVÉ, 2014), and 2. Harmful effects of climate change, which have intensified extreme drought events (PACHAURI et al., 2014). In addition ... Status: Completed Start date: Mon Apr 01 00:00:00 GMT-03:00 2019
