Abstract
This technique, known as the infector-hedge system, was found to be more convenient than the infector-row method for large-scale field tests. A four-rowed hedge of susceptible Cajanus cajan 'NP(WR)15' was planted along one side of a 2 ha field and infected by leaf-stapling with infected material. Average disease incidence across the field in indicator rows of susceptible BDN1 (planted every ten rows between test materials) was 98.7% at 104 days after plantin
