Syndrome of death of marandugrass in the Western Brazilian Amazon

摘要：

Introduction Brachiaria briz antha cv.Marandu (marandugrass) is well adapted to deep and well drained soils with medium to high fertility.Since its release in 1984,the high speed of establishment,resistance to spittlebug,vigorous plant regrowth,high forage yield and quality led to rapid adoption of this grass by farmers throughout Latin America.This resulted in over 60 million hectares of marandugrass pastures in Brazil,with more than 50％ in the Legal Brazilian Amazon.In 1994,farmers of Acre began to observe the death of marandugrass plants in some pastures (Valentim et al.,2000).The problem has also been reported in other regions of Brazil ( Teixeira Neto et al.,2000).
