Abstract

Disease management is the important aspect in determining the success of P. falcataria nursery. In the other hand, the information on disease management and technology to control disease P. falcataria nursery was limited. This study was conducted to disease inventory, to obtain information on technique for controlling disease in nursery of P. falcataria and to test of several control techniques. The study was conducted by observing, interviewing, testing several techniques of disease control, and laboratory examination. Disease control techniques consist of : tested two species of Trichoderma spp. to control damping-off disease, seed treatment on one and six months P. falcataria seedling to control the antrachnose disease. The pest and disease was founded at P. falcataria nursery which owned by CV. PMA (Parama Mulya Abadi) Desa Logending, Kec. Ayah, Kab. Kebumen is leaf-folder caterpillar, mealbug, and antrachnose disease. The Important disease in nurseries owned by CV. PMA was anthracnose caused by Colletothtrichum gloeosporioides. The tested of several techniques in P. falcataria nursery showed that the used of two species Trichoderma spp. was not effective to suppress antrachnose disease. Combination of micro fertilizer, yeast antagonists, and sanitation treatment were effective in suppressing the severity of antrachnose disease on one and six month old P. falcataria seedlings. The high intensity of antrachnose disease in nursery caused by several factors; weak of organisation fuction, unprecise used of technologies, high rainfall density, high moisture, and lack of valified human resources
