Abstract:
In order to predict the response of Cycloate and Chloridazon on germination of sugar beet seeds, a lab research was carried out in Seed Technology Laboratory, Mashhad Branch, Islamic Azad University in 2013. This research was done in two separate experiments in a completely randomized design with 14treatments and three replications. Treatments consisted of Cycloate at doses of 0, 18.175, 36.35, 72.7, 145.4, 290.8 and 581.6 g a. i./ha and Chloridazon at doses of 0, 37.5, 75, 150, 300, 600 and 800 g a. i./ha. The results showed that the seed germination percentage sensitivity of sugar beet at differentdoses of Cycloate were more than Chloridazon. So that the effective dose Cycloate and Chloridazon toreduce germination of 50% compared to control (ED50) were 46/2912 and 96/4463 g a.i. /ha respectively
