R.; GODINHO, V. de P. C.; MUNIZ, R.; SANTOS, L.; BRUGNERA, F.; MARCILIO, V.; CRUZ, P. G. da; SALMAN, A. K. D.; LOCATELLI, M.; WADT, P. G. S. Repository: BDPA Publication year: 2015
Temperature-dependent modeling and spatial predictions for identifying geographical areas in Brazil suitable for the use of Cordyceps javanica in whitefly control. Author(s): BOAVENTURA, H. A.; QUEIRÓS, L. A.; SILVA, J. F. A. e; GOBLE, T. A.; PAZOLINI, K.; MARCIANO, A. F.; QUINTELA, E. D. Lalguard C99 WP, based on the Cordyceps javanica BRM 27666 strain, is registered in Brazil for whitefly control. Spatial prediction is crucial for optimizing its field use and efficacy. In this study,... ... Repository: BDPA Publication year: 2025
