Abstract
Penyakit Tungro merupakan salah satu OPT golongan penyakit yang sering menyerang tanaman padi. Virus tungro sendiri terdiri dari 2 jenis yaitu Rice Tungro Bacilliform Virus (RTBV) dan Rice Tungro Spherical Virus (RTSV). Penyebaran virus tungro pada tanaman padi melalui vektor serangga wereng hijau. Secara umum gejala infeksi keduanya ditunjukan dengan daun berwarna kuning hingga oranye kemudian beberapa helai daun muda terpelintir serta tanaman menjadi kerdil. Survey ini dilakukan dengan metode purposif sampling di 3 kecamatan yaitu Kecamatan Trucuk, Polanharjo dan Gantiwarno. Setiap kecamatan dipilih 2 desa untuk dipasang plot pengamatan. Penelitian ini dilakukan pada plot dilahan tanaman seluas 1000 m2 . Setiap plot terdapat 5 subplot berukuran 2x2 meter yang menyebar secara diagonal. Pengamatan dilakukan sebanyak 5 kali dengan interval waktu 6 hari. Pengamatan ini dilakukan untuk mengetahui insidensi penyakit, laju infeksi penyakit, populasi vektor serta hubungan insidensi penyakit dan populasi vektor penyakit tungro. Hasil survey menunjukan pada 6 plot yang telah dilakukan pengamatan hanya pada plot 6 yang berlokasi di Desa Kragilan, Kec. Gantiwarno terdapat Insidensi/Kejadian penyakit Tungro. Rata-rata nilai insidensi penyakit tungro pada desa kragilan sebesar 14,36%. Jumlah populasi vektor (Wereng Hijau) yang ditemukan yaitu sebesar 1,53 ekor/100 rumpun. Rata-rata laju infeksi yang ditemukan di lahan pengamatan hanya sebesar 0,00395175 unit/hari. Uji korelasi/regresi menunjukan tidak adanya hubungan antara populasi vektor dengan insidensi tungro.
English Abstract
Tungro Disease one of the diseases that often attacks rice plants. The tungro viruses itself consists of 2 types, Rice Tungro Bacilliform Virus (RTBV) and Rice Tungro Spherical Virus (RTSV). The spread of tungro virus in rice plants through the vector (green leafhopper). In general, the symptoms of both infections are shown by yellow to orange leaves, then some young leaves are twisted and the plants become stunted. This survey was conducted using a purposive sampling method in 3 sub-districts, Trucuk, Polanharjo and Ganwarno. Two villages were selected for each sub-district to be installed as observation plots. This research was conducted on a plot of 1000 m2 plantation area. Each plot has 5 subplots measuring 2x2 meters which are spread diagonally. Observations were made 5 times with an interval of 6 days.This observation was carried out to determine the incidence of the disease, the rate of infection of the disease, the vector population and the relationship between the incidence of the disease and the population of the tungro disease vector. The survey results show that in the 6 plots that have been observed, only plot 6 is located in Kragilan, Gantiwarno, There is an Incidence/Occurrence of Tungro disease. The average incidence of tungro disease in Kragilan is 14.36%. The number of vector populations (Green Leafhoppers) found was 1.53 individuals/100 families. The average infection rate found in the observation fields was only 0.00395175 units/day. Correlation and regression test showed no relationship between vector population and tungro incidence.
