Abstract

Athelia rolfsii, Curzi adalah bentuk seksualitas dari spesies Sclerotium rolfsii, Sacc, salah satu spesies jamur patogen yang dapat menyebabkan beberapa penyakit mematikan pada tanaman seperti busuk batang, layu dan rebah kecambah. Jamur ini merupakan jamur tular tanah yang dapat bertahan lama dan membentuk sklerotia di dalam tanah. Biasanya serangan dari patogen A. rolfsii, Curzi, ini masyarakat petani cenderung mengendalikannya dengan pemakaian pestisida yang berbahan aktif kimia. Hasil monitoring pengendalian yang memakai fungisida sintetis dalam mengendalikan patogen menimbulkan dampak negatif, akibat dari residu pestisida pada produk pertanian, serta resistensi dan resurgensi penyakit. Oleh sebab itu perlu dicari pestisida sebagai pengendali yang tidak mempunyai dampak negatif. Diantaranya adalah pemakaian pestisida yang bahan aktif tanaman ataupun hayati. Dari hasil beberapa penelitian yang telah dilakukan, setiap bahan baku yang berbeda akan mempunyai daya hambat yang berbeda pula. Untuk itu akan diuraikan dibawah ini hasil-hasil penelitian sebagai pengendali A. rolfsii Cruzi dari golongan fungisida nabati dan agens hayati.ABSTRACTAthelia rolfsii, Curzi is a form of sexuality from the species Sclerotium rolfsii, Sacc, one of the pathogenic fungal species that can cause several deadly diseases in plants such as stem rot, wilting and drooping of sprouts. This fungus is a soil-borne fungus that can survive for a long time and form sclerotia in the soil. Usually the attack is from the pathogen A. rolfsii, Curzi, the farming community tends to control it by using pesticides with active chemical ingredients. The results of monitoring control using synthetic chemical fungicides in controlling pathogens have a negative impact, as a result of pesticide residues in agricultural products, as well as disease resistance and resurgence. Therefore it is necessary to look for pesticides as controllers that do not have a negative impact. Among them is the use of pesticides with active plant or biological ingredients. From the results of several studies that have been carried out, each different raw material will have a different inhibition power. For this reason, the results of research as controllers for A. rolfsii Cruzi will be described below from the class of botanical fungicides and biological agents.
