Abstract


Soil fertility can pressure rate attack of gummosis disease on cashew nut plantation in Muna Regency South-East Sulawesi. Blendok disease or gummosis have disseminated on some cashew plantation in Muna Regency, South-East Sulawesi. There was a correlation between soil fertilities and disease spreading. This assessment was intended to know the level attack and damage which were resulted from disease of gummosis at cashew crop. The assessment was conducted at Fongkaniwa Village of Muna Regency South-East of Sulawesi in 2004, using the rural cashew nut plantation in 30 ha area. The assessment area was divided into three blocks, i.e. high, moderate, and low level of soil fertility. Result of study indicated that attack intensity of gummosis disease on cashew nut are 19.49 %, 30.43 %, and 50.03 % on each levels of soil fertility, while Rate of Attack by the score value of 0.16, 1.14, and 1.77. Result of study indicated that improvement of soil fertility of cashew plantation are very important to pressure of attack and damage of gummosis disease.

 

 

Penyakit blendok atau gummosis telah menyebar di beberapa pertanaman mete di Kabupaten Muna, Sulawesi Tenggara. Meluasnya serangan penyakit diduga berkaitan dengan tingkat kesuburan lahan. Pengkajian ini dimaksudkan untuk mengetahui tingkat serangan dan kerusakan yang diakibatkan oleh penyakit blendok pada tanaman jambu mete. Kajian dilaksanakan di Desa Fongkaniwa Kabupaten Muna Sulawesi Tenggara tahun 2004 pada pertanaman jambu mete rakyat seluas 30 ha. Areal pengkajian dibagi menjadi tiga kelompok berdasarkan tingkat kesuburan tanahnya yaitu kesuburan tinggi, sedang, dan rendah. Pengamatan penyakit blendok dilakukan dengan mencatat jumlah pohon menunjukkan gejala penyakit, yaitu keluarnya getah kental berwarna coklat pada pohon dan cabang. Hasil kajian menunjukkan bahwa populasi terserang penyakit blendok masing-masing 19,49 % pada lahan kesuburan tinggi, 30,43 % pada lahan kesuburan sedang, dan 50,03 % pada kesuburan rendah. Tingkat Serangan masing-masing tergolong sedang pada kesuburan lahan rendah dan ringan pada lahan subur yaitu dengan nilai skor masing masing 0,16; 1,14; dan 1,77 pada setiap tingkat kesuburan tanah. Hasil pengkajian menunjukkan bahwa peningkatan kesuburan tanah pada pertanaman jambu mete sangat penting untuk menekan tingkat serangan dan kerusakan penyakit blendok.
