Abstract

We investigated occurrence of yellow patch for early spring season of 48 cultivars in 5 species of turfgrass, most popularly used in Korea golf courses. Only yellow patch disease caused by Rhizoctonia cerealis was occurred naturally from late fall season. Perennial ryegrass and creeping bentgrass cultivars showed susceptibility from yellow patch in early spring, respectively. However, among There was no significantly different between the other species. Creeping bentgrass, 'Pennlinks II' cultivar was the most susceptible. Yellow patch symptom showed reddish brown with margins in color and patch showed size from 5 cm to 50 cm in diameter. Based on our results, Yellow patch showed large differences among cultivar and each turfgrass species.

우리나라 골프장에 조성된 한지형 잔디 5종류 48품종(creeping bentgrass 9품종, kentucky bluegrass 20품종, tall fescue 10품종, perennial ryegrass 5품종, chewing fescue 4개 품종)에 대하여 봄철에 발병하는 병의 종류와 병의 심각성을 평가하였다. Rhizoctonia cerealis에 의해 늦가을부터 자연적으로 발병한 yellow patch 뿐 이었다. 잔디 종류 중에서 Perennial ryegrass 품종과 creeping bentgrass 품종에서 이른 봄에 심각하게 발생한 반면, 다른 종류의 품종들은 통계적으로 유의성이 없었다. Creeping bentgrass 품종 중에는 "Pennlinks II"가 가장 감수성을 보였다. Yellow patch의 증상은 가장자리가 자줏빛갈색을 보였으며, 직경의 크기는 5 cm-50 cm 이었다. 이결과로 볼 때 yellow patch의 발병 률은 잔디 종류와 품종 간에 큰 차이를 보였다.
