Seed coating of carrot seeds: effects on physiological quality

The objective of this study was to evaluate the physiological quality of coated carrot seeds after coating with agglomerate (Vermiculite) in proportions of 2:1 and 3:1; and the addition of the fungicide Thiram + Carbendazin, together with sticker (Polyvinyl Acetate) and colorant "color coat". The physiological quality of coated carrot seeds (Daucus carota L.) cv. Tropical was evaluated by the standard germination test, germination first count, accelerated aging, cold test, field emergence, greenhouse emergence, speed of germination index and emergence index. Carrot seed coating with fungicide Thiram 600g + Carbendazin 200g, with a concentration of 0,25% (250mL of fungicide for each 100kg of seed), agglomerate in the proportion 3:1 and coloring color coat did not interfere in the physiologic quality of the seeds. Carrot seed coating increased seed moisture content in approximately 16 percentile points, so drying should be immediate.
