Abstract

Experiments were carried out to study on control of stem blight of asparagas caused by Shoma asparagi Sacc. in Suweon, $1976\~1978$. Symptoms of the disease were found in the field from late of May and severe infection was shown thereafter. Plastic film mulching with foliage spray of Topsin 154g a.i. and Difolatan 220g a.i. per 10a at 10days interval during the growing season, gave significantly good control and high yield compared with other treatments. In addition to reduction of the disease, the treatment with mulching has maintained good soil moisture for asparagus growth when the soil moisture was measured at about loom under the soil surface from July to August.

아스파라가스 줄기 마름병 (경고병)의 효과적인 방제 대책을 수립하고자 시험한 결과 1. 줄기 마름명은 5월하순부터 발생하여 7월이후 강우와 함께 급격히 증가하였고, 2. 약제살포를 겸하여 모경대치하고 plastic film으로 피복하였을 해가 약제살포만 할때보다 줄기 마름병의 발생이 현저히 줄어들었다. 3. Plastic film으로 피복하였을 때의 $7\~8$월중 토양 수분변화는 아스파라가스의 생육에 적당한 pF 2.9에 비교적 가까은 상태를 유지할 수 있었다. 4. 모경대치를 할 겅우 대조구보다 수량이 떨어졌으나 plastic film을 피복할 경우는 대조구보다 약 $30\%$ 정도 증수되었다.
