Penyakit daun keriting kuning/PYLCV

Penyakit daun keriting kuning/PYLCV (Pepper Yellow Leaf Curl Virus) memiliki gejala yang khas meliputi : tulang daun menebal, tepi daun menggulung ke atas, dan helaian daun berwarna kuning cerah. Tanaman yang mulai terserang pada umur muda menjadi kerdil dan tidak berbuah. Penyakit daun keriting kuning cabai ditularkan oleh serangga vektor, yaitu kutukebul (Bemisia tabaci Genn.). Buah maja memiliki kandungan saponin, tanin, marmelosin, minyak atsiri, dan pektin yang tidak disukai oleh hama tumbuhan. Sedangkan urine kelinci merupakan sumber PGPR yang dapat menghambat perkembangan fitopatogen melalui mekanisme aktivitas metabolit sekunder dan zat anti mikroba yang memiliki aktivitas antagonis Penelitian ini bertujuan untuk mengetahui bagaimana tingkat kemanjuran campuran ektrak buah dan urine kelinci dalam mengendalikan penyakit daun keriting kuning pada tanaman cabai rawit. Penelitian dilakukan di Desa Sukoreno Kecamatan Kalisat pada bulan juli hingga Oktober 2019. Data yang diperoleh yaitu meliputi insidensi penyakit setiap minggu pada setiap sampel tanaman, keparahan penyakit setiap minggu pada setiap sampel tanaman, laju infeksi, serta dianalisis dengan uji jarak duncan (DMRT) dengan taraf kepercayaan 5%. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) non faktorial dengan 6 perlakuan dan 4 ulangan, sehingga didapatkan 24 unit percobaan. Adapun perlakuan yang digunakan yaitu Kontrol (tanpa perlakuan), EBM 100 ml/l air, EUK 100 ml/l air, EBMUK 100 ml/l air, EBMUK 150 ml/l air, dan EBMUK 200 ml/l air.Hasil penelitian menunjukkan bahwa campuran ekstrak buah maja dan urine kelinci dapat menghambat keparahan penyakit daun keriting kuning. Perlakuan EBM 100 ml/l dapat menekan penyakit sebesar 1.59 %, EUK 100ml/l air dapat menekan penyakit sebesar 1.82 %, EBMUK 100 ml/l air dapat menekan penyakit sebesar 2.27 %, EBMUK 150 ml/l air dapat menekan penyakit sebesar 2.52 %, dan EBMUK 200 ml/l air dapat menekan penyakit sebesar 5.42 %. Secara umum semakin tinggi konsentrasi campuran ekstrak buah dan urine kelinci dapat memberikan daya hambat yang semakin tinggi. Hal tersebut berkaitan dengan senyawa metabolit sekunder dan zat amti mikroba yang dihasilkan oleh PGPR.

Yellow leaf curl disease / PYLCV (Pepper Yellow Leaf Curl Virus) have typical symptoms include: bone thickened leaves, leaf edges curl upward, and a bright yellow leaf blade. Plants that started developing at a young age become stunted and fruitless. Chili yellow leaf curl disease transmitted by insect vectors, namely kutukebul (Bemisia tabaci Genn.). Maja fruit contain saponins, tannins, marmelosin, essential oils, and pectin which is not favored by plant pests.
The study was conducted in the village of the District Sukoreno Kalisat in July and October 2019. The data obtained by the incidence of the disease include every week in every sample of plants, severity of the disease every week on each plant sample, the rate of infection, and analyzed by Duncan range test (Duncan Multiple) with 5% confidence level. This study uses a randomized block design (RAK) non factorial with 6 treatments and 4 replicates, so we get 24 experimental units. The treatment used is the control (no treatment), EBM 100 ml / l of water, eUK 100 ml / l of water, EBMUK 100 ml / l of water, EBMUK 150 ml / l of water, and EBMUK 200 ml / l of water.
The results showed that a mixture of fruit extracts maja and rabbit urine can inhibit the severity of the disease yellow leaf curl. Treatment EBM 100 ml / l can suppress the disease by 1:59%, eUK 100ml / l water can suppress the disease by 1.82%, EBMUK 100 ml / l of water can suppress the disease by 2:27%, EBMUK 150 ml / l of water can suppress the disease by 2:52% and EBMUK 200 ml / l of water can suppress the disease by 5:42%. In general, the higher the concentration of the mixture of fruit extracts and rabbit urine can provide higher power resistor. It relates to secondary metabolites, compounds and substances produced by microbes AMTI PGPR.

Yellow/PYLCV (Pepper Yellow Leaf Curl Virus) has typical symptoms include: The bone is thickened, the edges of the leaves roll up, and the leaf sheet is bright yellow. Plants that began to be attacked at a young age became dwarfs and did not bear fruit. The disease of curly yellow chili leaves is transmitted by vector insects, namely Kutukebul (Bemisia Tabaci Genn.). The fruit of Maja has saponin, tannins, marmelosin, essential oils, and pectin that is not liked by plant pests. While rabbit urine is a source of PGPR that can inhibit the development of phyyogens through the activity mechanism of secondary metabolites and anti-microbial substances that have antagonistic activity the research aims to find out how the efficacy of a mixture of fruit and urine extract of rabbits in controlling the yellow curly leaf disease in cayenne pepper plants.
Research conducted in Sukoreno village of Kalisat subdistrict from July to October 2019. The Data obtained is covering the incidence of diseases every week on each sample of plants, the severity of the disease every week on each crop sample, the rate of infection, and analyzed by Duncan Distance test (DMRT) with a level of 5% confidence. The study used non-factorial group random design (RAK) with 6 treatments and 4 repeats, resulting in 24 experimental units. The treatment used is control (without treatment), EBM 100 ml/l water, EUK 100 ml/l water, EBMUK 100 ml/l water, EBMUK 150 ml/l water, and EBMUK 200 ml/l water.
The results show that the mixture of Maja fruit extracts and rabbit urine can inhibit the severity of yellow curly leaf disease. EBM Treatment 100 ml/L can suppress disease by 1.59%, EUK 100ml/l water can suppress disease by 1.82%, EBMUK 100 ml/l water can suppress the disease by 2.27%, EBMUK 150 ml/l water can suppress the disease by 2.52%, and EBMUK 200 ml/l water can suppress the disease by 5.42%. In general the higher concentrations of mixed fruit extracts and urine rabbits can provide an increasingly high resistance. It relates to a compound of secondary metabolites and microbial amti substances produced by PGPR.
