PURPOSE

The sugarcane crop is subject to several diseases. Therefore, knowledge of phytosanitary controls to produce healthy seeds is a fundamental factor.

The roguing operation, to prevent diseases spreading, reduce the inoculation of pathogens in the seedlings and avoid mixtures of varieties, is an important system that requires specific knowledge and training, allowing the maintenance of a high level of health in nurseries and basic conditions so that the seedlings have the desired quality.

Heat hot treatment does not efficiently control all sugarcane diseases, nor does it even prevent them from being infected again, through inoculations introduced by man himself or other means of contamination. Therefore, constant surveillance in nurseries is necessary to prevent these diseases from compromising the production of seeds.

To guarantee quality in the seeds production process, UFSCar offers the “Roguing Training Course”, to enable individuals for the roguing activities, providing technical information and practical training for the recognition and solution of sugarcane phytosanitary products.
