Effect of Insecticides to Brown Planthopper (Nilaparvata lugens Stal) Adaptation on Resistant Rice Varieties. Brown planthopper (BPH) (Hemiptera: Delpachidae) is one of major pests on rice cultivation in Indonesia. Resistant rice varieties and insecticides are commonly used by farmers in BPH management. But, BPH can rapidly adapt on long-term planted varieties and insecticide. The aim of research was to study the ability of insecticide resistance BPH in adaptation on resistant rice varieties. This study was conducted at Indonesian Center for Rice Research from October 2018 to June 2019. BPH?s were collected from farmer field and reared for 6th generation. BPH?s were divided into four insecticide population. BPH population sprayed each generation by BPMC (BPMC-BPH), imidacloprid (imidacloprid-BPH), pymetrozine (pymetrozine-BPH), and unsprayed (Control-BPH). In first generation, insecticide resistance conducted to obtain baseline data of BPH resistance to imidacloprid, BPMC and pymetrozine. On 6th generation, insecticide resistance test repeated to each population. Four BPH population were tested for the survival rate, fecundity, amount of honeydew, and rice varieties reaction. Result showed that Field population 1st generation were resistance to BPMC and imidacloprid with Resistance Factor (RF) 4.1 and 13.5-fold, respectively, while to pymetrozine was indicate resistance (RF 3.7-fold). In 6th generation, LC50 all insecticide population were increased, while in Control-BPH were decreased. Inpari 13 still effective againts BPH in all test results. Insecticide resistance-BPH tend to lower adaptation on resistant variety than insecticide susceptible-BPH.

Maize Downy Mildew caused by pathogenic fungus of Peronosclerospora philippinensis is an important disease in centers of maize crops outside Java Island. Research on â€œThe Appearance ofÂ MaizeÂ Downy Mildew Caused by Pathogenic Peronosclerospora philippinensis in Combination Treatment of Resistant Varieties and Metalaxyl Fungicide â€ aimed to determine the effectiveness of a combination of fungicide treatment of active ingredients of metalaxyl with varieties that have resistance to Maize Downy Mildew which was caused by P.philippinensis species. This research was conducted at KP Bajeng (endemic area ofÂ Maize Downy Mildew of P. Philippinensis species), which was compiled in Separate Plot Design with 3 replications. The main plot contained 5 varieties of maize, namely: (1) Bima-3 Bantimurung, (2) Bima-20 URI, (3) Lagaligo, (4) Bima-15 Sayang, and (5) Anoman. On the other hand, the sub plot contained 5 levels of seeds treatment dose with Metalaxyl Fungicide Active Ingredient (0 g/kg, 2 g/kg, 3 g/kg, 5 g/kg, and 7 g/kg of maize seed). The results showed that the combination of resistant and susceptible varieties with Metalaxyl Active Ingredient at doses of 2g, 3g, 5g and 7g/kg of maize seed controlled the Maize Downy Mildew which was caused by the Peronosclerospora philippinensis species effectively. It was shown by the low reaction of Maize Downy Mildew infection, at the percentage of 0% -1,86%, respectively. Under the circumstances of susceptible varieties without Metalaxyl Active Ingredient treatment, the intensity of Maize Downy Mildew reached the percentage of 100%. The lower intensity was also followed by the production, cob length and weight of 1000 seeds that were higher than those of control treatment.

White stem borer Scirpophaga innotata Walkers is known as a species that always causes loss of rice yields in Indonesia and the Asia region and Australia. White stem borer attacks all stages of rice plant growth starting in the nursery until harvest. Until now, synthetic chemical pesticides are still a mainstay of farmers in controlling these pests. Then it is necessary to promote biological pest management, the use of biological agents is pest management technology because a save, economical and effective. Biological control through multiplication and parasitoid release needs to be focused on parasitoid it has adapted to the local environment. This study aims to examine the role of egg parasitoid S. innotata through the type and level of egg parasitization at various phases of rice plant growth. This research was conducted by collecting as many white rice stem borer eggs as possible based on the growth phase of rice plants, i.e. age 11-25 days after planting (DAP), 26-40 DAP, 41-55 DAP, 56-70 DAP, and 71-85 DAP. Observations were made by counting hatching and non-hatching eggs, as well as the type and number of parasitoids that appeared. The results show that the egg parasitoid found was Trichogramma japonicum Ashmead, Tetrastichus schoenobii Ferriere, Telenomus rowani Gahan. The highest level of egg parasitization is at 71-85 DAP.

Adoption of the hybrid rice varieties by farmers is often impaired by the high price of hybrid seed, due to low yields in hybrid seed production fields. Female outcrossing ability and female hybrid seed production ability, defined as the rate of filled spikelets of the male sterile line and as its grain yield under outcrossing, respectively, determine plant traits for hybrid seed yield. We identified an morphological characters and outcrossing rate ability of 6 hybrid rice combination that affect grain yield of hybrid rice seed production. The experiment conducted in 3 locations i.e. Subang, Malang, and Ungaran districts during dry season of 2016. Subang is the best location to hybrid rice seed production with the highest average of grain yield. Hipa 19 was the hybrid varieties having > 1 ton/ha grain yield highest that others. The important agronomic characteristics that affected of F1 grain yield i.e. plant height, number productive tillers, number of filled grains, exerted panicle rate, dan outcrossing rate. Correlations between number of filled grains, outcrossing rate, and grain yield were tight and highly significant. High yield potential and cost-effective for hybrid seed production can be achieved using hybrid rice with high outcrossing rate and suitable condition of an environment.

East Java Province supplies one third of the national peanut production. The farmland of peanut production centers in the region is a coastal area prone to salinity. The use of variety adaptive to salinity stress is an effective strategy to cope sainity problem and to optimize the use of salt-affected land. The aim of the research was to evaluate the adaptability of peanut varieties to salinity stress.The research was conducted in the 2018 dry season in the saline paddy field in Gesikharjo Village, Palang Sub District, Tuban Regency with EC 14.54 dS/m. The treatments consisted of seven groundnut varieties (Singa, Singa, Kancil, Takar 2, Bison, Hypoma 2, Tuban, and Jerapah), using a randomized complete design, four replications. Observations consisted of growth parameters, yield and yield components, proline and macro nutrient (N, P, K) content. The results showed that high salinity stress reduced seed germination, plant growth, yield components and yields of all varieties tested. Based on the ability to survive and yield, Singa variety have showing higher tolerance to salinity stress or more adaptive than other varieties, while the lowest one was found in Jerapah variety. The salinity tolerance of Singa variety did not indicate to be associated with high proline content, but it seem more related to the ability to absorb higher N, and keep K high to reduce negative effect of Na.
