Salah satu faktor pembatas produktivitas cabai rawit (Capsicum frutescensL.) di Indonesia adalah gangguan hama dan penyakit. Antraknosa (Colletotrichum capsici) merupakan penyakit utama yang menyebabkan rusaknya buah muda ataupun tua utamanya pada musim penghujan. Penelitian ini bertujuan untuk mengetahui efektifitas fungisida berbahan aktif mankozeb dan karbendazim, propineb, klorotalonil terhadap tingkat serangan antraknosa pada buah cabai. Penelitian ini dilaksanakan di Desa Poreh, Kecamatan Lenteng Kabupaten Sumenep, Madura dari bulan November 2015-Januari 2016. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) non faktorial terdiri dari empat perlakuan, yaitu kontrol, mankozeb dan karbendazim, propineb, klorotalonil yang diulang 3 kali. Hasil penelitian menunjukkan bahwa perlakuan mankozeb dan karbendazim berpengaruh nyata terhadap semua variabel pengamatan.Jika dibandingkan dengan kontrol,perlakuan mankozeb dan karbendazim memberikan efektifitas pengendalian 63,52% dan efektifitas produksi 58,46% serta produksi 1349,59 kg/ha. Kata kunci: Cabairawit, antraknosa(Colletotrichum capsici), fungisida, efektifitas, produksi.

One of the factors limiting the productivity of chili (Capsicum frutescens L.) in Indonesia is as pests and diseases. Anthracnose (Colletotrichumcapsici) is the main disease that causes damage to young or old fruit mainly in the raining season. This study aims to determine the effectiveness of the fungicide active ingredient mankozeb and karbendazim, propineb, klorotalonil against anthracnose attack rate in chilies. This research was conducted in the Poreh village, Lenteng District Sumenep Madura, from November 2015 unti January 2016. This study used a completely randomized design (CRD) non factorial consisted of four treatments, ienon treatmen, mankozeb and karbendazim, propineb, klorotalonil repeated 3 times. The results showed that the treatment of mankozeb and karbendazim significantly affected all the variables observation. When compared with the non treatment, mankozeb and karbendazim provide effective of control 63.52% and 58.46% effective of production as well as production 1349.59 kg / ha. Keywords:,chili (Capsicum frutescens L.), antraknosa (Colletotrichumcapsici), fungicides, effective, production.
