Abstract: Safflower (Carthamus tinctorius L.) presents a high susceptibility for the attack of pathogens, resulting in low productivity of seeds. Thus, we aimed to evaluate the physiological and sanitary quality of safflower seeds submitted to different treatments. The experiment was conducted in the Floricultural Sector and in the Didactic and Seed Research Laboratory, in completely randomized design, with 4x9 (lots of seeds and treatment of seeds), with four repetitions. The lots of seeds were cultivated in the crop 2017/2018, the sowing occurred in the first fortnight of each season of the year (autumn, winter, spring and summer). After collected, the lots were stored in cold chamber with average degree of humidity of 9.0%. The treatments of seeds were constituted by: control, thermotherapy via humid heat, thermotherapy via dry heat, Trichoderma harzianum, chemical fungicide with active ingredients of Carbendazim+Thiram, Metalaxyl-M+Fludioxonil and Carboxin+Thiram, vegetal extracts of Dendranthema grandiflora and of Melia azedaeach. We evaluated the seeds treated by the standard test of germination, length and mass of seedlings, emergence and sanity. We observed that all the tested treatments benefit the safflower culture, promoting improvement in its germination, with efficient establishment of seedlings in the field. At the same time that was carried out the infestation control of the pathogens on the same, among the treatments we highlight the chemical fungicide with active ingredient Carbendazim+Thiram.
