Summary This paper presents studies on the life cycle of Heterodera sacchari under in vitro conditions. Pluronic gel was used as a medium for growth of H. sacchari. The life cycle was completed in 7-9 weeks on rice (Oryza sativa, ‘Nipponbare’). After infection, juveniles developed and reached the reproducing adult female stage at 25 days post inoculation (dpi). At 35 dpi, all females produced eggs in various numbers. Some females were translucent and eggs inside could be counted. At 49 dpi females started to tan and developed into dark brown cysts. Hatching of H. sacchari juveniles from cysts could be stimulated by 3 mM ZnCl2 but not by rice root exudates. The in vitro culture of H. sacchari on Pluronic gel can be used efficiently to collect post-infective nematode/host samples at different time points for various studies and to screen different rice cultivars for resistance/susceptibility.

Keragaan morfologi dan kandungan antosianin padi beras merah (Oryza sativa L.) pada Kecamatan Munte dan Kecamatan Payung di Kabupaten Karo. Penelitian ini bertujuan untuk mendapatkan informasi morfologi dan kandungan antosianin padi beras merah (Oryza sativa L.). Penelitian ini dimulai dari Juni 2017dan selesai pada Januari 2018 di kecamatan Munte dan Kecamatan Payung Kabupaten Karo.Metode survei deskriptif menggunakan panduan International Rice Research Institute (IRRI). Teknik penentuan lokasi secara sengaja dan pengamblan sampel secara kebetulan.Uji kandungan antosianin menggunakan metode analitik dengan menghomogenkan sampel. Hasil eksplorasi didapatkan 72 genotipe yang dibagi menjadi tiga lokasi lahan. Berdasaran uji kandungan antosianin didapatkan lahan A memiliki kandungan tertinggi yaitu 0,5 mg/100 g dan terendah yaitu lahan B 0,08 mg/100 g.

Experiments were carried out to assess some insecticide modules against major insect pests of rice. Each module consists of a basal application of carbofuran 3G @ 1 kg a.i ha-1 at 20 DAT and Rynaxypyr 20 SC @ 30 g a.i ha-1 at 45 DAT except untreated control. All modules differ with each other only in third treatment which was applied in 65 DAT. The third treatment includes: Imidacloprid 17.8 SL @ 27 g a.i ha-1, Pymetrozine 50 WG @ 150 g a.i ha-1, Triflumezopyrim 106 SC @ 27 g a.i ha-1, Buprofezin 25 SC @ 250 g a.i ha-1; Glamore (Imidacloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1, Thiacloprid 24 SC @ 60 g a.i ha-1, Azadirachtin 0.03 EC @ 8 g a.i ha-1, Dinotefuran 20 SG@ 40 g a.i ha-1 and untreated control. All the treated plots recorded significantly lower percent of dead heart, white ear- head caused by stem borer and silver shoot caused by gall midge. Module with Pymetrozine 50 WG @ 150 g a.i ha-1 treated plot recorded significantly higher per cent reduction of plant hoppers (>80% over untreated control) and produced higher grain yield (50.75 qha-1) than the other modules. Among the different treated modules the maximum number of spiders was found in Azadirachtin 0.03 EC @ 8 g a.i ha-1 treated module plot followed by other treatments.
