Based on the conducted experiments, we can state that the basic factor determining the level of sunflower moth infestation is the flowering time influenced by growing period of the variety and sowing date. As the sowing date starts later and later, the number of days to flowering decreases, but it cannot compensate for the greater extent of moth contamination resulting from the later blooming. Thus, an early sowing is recommended for the variety Kisvarda, not only to increase the yield but also to decrease the rate of moth infestation.
