“…However, he observed insignificant variation of grain amylose and protein content, total phenol and ortho-dihydroxy phenol amount under different fertilizer treatments, while the plant moisture content increased with the increase in N fertilizer dose. Planthopper population responded positively to nitrogen fertilizer (Lu et al 2004;Lu et al 2005), and it act as a major cause of BPH outbreak (Bottrell and Schoenly 2012).…”

The experiments for determining the multiple insect-pest incidence on yield loss in basmati rice was conducted for two crop seasons. Five treatments were, viz. application of imidacloprid in vegetative stage; application of granular insecticide in vegetative stage; application of higher dose of Urea; augmentive releases of yellow stem borer egg mass at vegetative and booting stage; untreated control. During both the years, the correlation between grain yield and dead heart, leaf folder damage and planthopper population at 50 and 65 DAT and white ear at maturity was negative. The analysis of variance of regression analysis of yield Vs damage levels at different crop growth stages during both the years revealed a significant linear relationship. The yield loss was highly related to incidence of stem borer and leaf folder damage at 50 and 65 DAT during both the years. For integrated pest management, effective monitoring of stem borer and leaf folder from 50 to 65 DAT is required, which appeared as a critical crop growth stage. The farmers should remain cautious during this period to prevent yield loss.

“…Menurut Bottrell & Schoenly (2012), hama ini mulai menjadi masalah serius pada budidaya padi sejak adanya gerakan revolusi hijau. Nimfa dan imago WBC hidup berkelompok dan mengisap cairan tanaman pada bagian pangkal rumpun tanaman padi, sehingga menyebabkan kerusakan ekonomi yang parah (Baehaki, 2011).…”

Sublethal dose effect of imidacloprid on the survival of brown planthoppers on resistant and susceptible rice varieties.Imidacloprid insecticides and resistant rice varieties are commonly used to control the the rice brown planthopper (BPH) Nilaparvata lugens in the field. The aim of this research was to evaluate the resistance of N. lugens to imidacloprid and the influence of sublethal dose of the insecticide applied to a certain resistant rice varieties on the survival of BPH. The experiment was conducted in a greenhouse trial at Indonesian Center for Rice Research, Sukamandi, West Java. Each pair of adult BPH were infested on three rice varieties Ciherang, Inpari 13, and Pelita, and then followed by spraying five doses of imidacloprid. The the effective dose rate of imidacloprid on BPH was determined by the value of LD 95 compared with the recommended dose (20 g a.i. ha -1 ). The nymphal survival was concidered as a result of the applied sublethal doses. The numbers of nymphal progenies were observed until two peaks populations of both first and second generations. The insecticide then was applied at LD 50 dose equivalent on adult BPH of the second generation. The number of laid eggs and the abnormal egg shapes were counted. Imidacloprid doses that were unefffective against BPH showed by the values of LD 95 were 1224.3, 2799.0, dan 4692.8 g a.i. ha -1 at Ciherang, Inpari 13 dan Pelita rice varieties, respectively. Seven days after application of imidacoprid, about 70-90% of adult BPH still survived. Sublethal dosages of imidacloprid tended to increase the survival of BPH on a resistant rice variety of Inpari 13, as reflected by the number of nymphal progeny of 156-169 BPH/plant at the first population peak. Imidacloprid treatment increased the number of laid egg, but had no effect on the egg sterility.Key words: effectiveness, Nilaparvata lugens, oviposition, population survival ABSTRAK Pengaruh dosis subletal imidakloprid terhadap kesintasan populasi wereng coklat pada varietas padi rentan dan tahan. Insektisida imidakloprid dan varietas padi tahan wereng sering digunakan untuk mengendalikan populasi hama wereng batang coklat (WBC) Nilaparvata lugens di lapangan. Penelitian ini bertujuan menguji tingkat ketahanan WBC terhadap insektisida imidakloprid dan pengaruh dosis subletal terhadap sintasan populasi WBC pada varietas padi yang telah diketahui tipe ketahanannya. Penelitian dilaksanakan di rumah kaca Pusat Penelitian Padi Indonesia, Sukamandi. Sepasang imago WBC diinfestasikan pada tiga varietas padi (Ciherang, Inpari 13, dan Pelita), kemudian diberi lima dosis perlakuan imidakloprid. Keefektifan imidakloprid terhadap WBC ditentukan dari nilai LD 95 relatif terhadap dosis anjuran penggunan di lapangan 20 g b.a./ha. Nimfa yang lolos hidup dari pengujian ini dianggap sebagai perlakuan dosis subletal pada pengujian selanjutnya. Jumlah nimfa diamati hingga dua puncak populasi generasi ke-1 dan ke-2. Dosis perlakuan LD 50 diujikan kembali pada imago WBC generasi ke-2. Jumlah telur yang diletakkan dan ...

“…Severe infestations of brown planthopper have become more frequent in recent years in Indonesia and other tropical countries, due largely to the excessive use of nitrogen fertilizer on hybrid rice varieties and the misguided use of insecticides that destroy beneficial predators [81][82][83][84][85]). The loss of biodiversity in regions where rice production dominates the landscape also contributes to higher rates of infestation, as there is less supportive habitat for beneficial predators [86].…”

Rice production is susceptible to damage from the changes in temperature and rainfall patterns, and in the frequency of major storm events that will accompany climate change. Deltaic areas, in which millions of farmers cultivate from one to three crops of rice per year, are susceptible also to the impacts of a rising sea level, submergence during major storm events, and saline intrusion into groundwater and surface water resources. In this paper, I review the current state of knowledge regarding the potential impacts of climate change on rice production and I describe adaptation measures that involve soil and water management. In many areas, farmers will need to modify crop choices, crop calendars, and soil and water management practices as they adapt to climate change. Adaptation measures at the local, regional, and international levels also will be helpful in moderating the potential impacts of climate change on aggregate rice production and on household food security in many countries. Some of the changes in soil and water management and other production practices that will be implemented in response to climate change also will reduce methane generation and release from rice fields. Some of the measures also will reduce the uptake of arsenic in rice plants, thus addressing an important public health issue in portions of South and Southeast Asia. Where feasible, replacing continuously flooded rice production with some form of aerobic rice production, will contribute to achieving adaptation objectives, while also reducing global warming potential and minimizing the risk of negative health impacts due to consumption of arsenic contaminated rice.
