연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

Fourteen Bacillus thuringiensis isolates having both insecticidal activity and in vitro antifungal activity were selected and tested for in vivo antifungal activity against tomato late blight, wheat leaf rust, tomato gray mold, and barley powdery mildew in growth chambers. All the isolates represent...

제안 방법

  • Dimethomorph (10 μg/ml) for tomato late blight, fludioxonil (50 μg/ml) for tomato gray mold, flusilazole (10)ig/ml) for wheat leaf rust and barley powdery mildew were applied as positive controls. Experiments were conducted twice in a growth chamber, and the mean value of six estimates for each treatment was converted into percentage disease control. The percentage of disease control was determined using the following equation: % controle 100[(A-B)/A], where A=the area of infection (%) on leaves sprayed with Tween 20 solution alone and B=the area of infection (%) on treated leaves.
  • The suspensions were sprayed, using hand sprayers to run-oflfe on potted cucumber plants at the six-leaf stage. Treatments were made twice, with an interval of a week, starting immediately after the appearance of symptoms of powdery mildew on the first and second leaf. Tween 20 (250 jig/ ml)-treated plants were used as controls.

대상 데이터

  • Pots were arranged as a randomized complete block with four replicates per treatment. The experiments were repeated twice, for a total of eight plants tested in each variant. Disease severity was rated on ten leaves (leaves 3-12) per plant, 7 days after the second treatment.
