RESPON ENAM KLON KARET TERHADAP FUSICOCCUM SP. PADA DAUN KARET( HAVEA BRASILIENSIS. Agr)
Daftar Isi:
- Indonesia is the second largest rubber producing country in the world after Thailand, from 2009 to 2010 rubber production experienced a low increase of only 6.21 percent from 2.4 million tons in 2009 to 2.6 million tonnes in 2010. Low productivity of Indonesian rubber caused by the number of rubber plants that are old and damaged by disease. The disease Fusicoccum or deciduous leaves include a moderately complicated problem facing the national rubber plantation. In fact, according to the research results of the Sembawa Rubber Research Hall rubber production dropped to 45 percent. This disease has been spreading since the year 2017 ago. This became a major threat to the national rubber production The purpose of this acquisition is to know the response of six rubber clones both the infection process and the progression of the disease leaves Fusicoccum sp. The research was designed according to The draft random group (RAK) consists of 6 treatments (clones) and 6 repeats,. The results of this study are seen that the most clones resistant to the disease of autumn leaves Fusicoccum is RRIC 100 and IRR 112 ie at 10.15% and 17.53%. Whereas clones IRR 118 and BPM 24 include a somewhat resistant clone. For clones of PB 340 and PB 260 are categorized into somewhat vulnerable categories where the percentage of disease severity is 74.03% and 60.13% both clones are the most vulnerable and alleged clones due to low endurance and weak crop conditions.
