Research in the South Pacific has identified banana varieties with potential resistance to black leaf streak, also known as black sigatoka. The promising disease-resistant material has been screened from banana varieties imported to Western Samoa from Queensland, Australia. The disease was first recorded in Java in 1902 and in 1912 appeared in the Sigatoka Valley of Fiji, from whence it acquired its name. However, the disease was only recognized as a major threat when a very virulent form was detected in Fiji in 1963. Distinguished by severe dark brown and black spots and streaks on affected leaves; it was typified as black sigatoka or black leaf streak. Whereas the original mild form of sigatoka is caused by Mycosphaerella musicola, the virulent black leaf streak is caused by M. fijiensis. The disease has spread to many parts of Africa and to parts of the Caribbean basin. It is approximately three to six times more expensive to control M. fijiensis than M. musicola using fungicide spraying. The development of resistant varieties would be of great economic benefit to banana-dependent economies in the ACP countries.
