Pomacea spp. or apple snails are one of the main rice pests in Malaysia. It is unfortunate that farmers prefer to use chemical molluscicides especially the illegal mollusicicides from other countries to control this pest. The use of chemicals brings negative effect to farmer's health and environment. One of the suggested measures to avoid the excessive use of chemical molluscicides is by physical control through handpicking. However, manual handpicking is backbreaking and not very effective. The use of attractant baits can ease the hard work of manual handpicking or enabling spot spraying of molluscicides which minimizes the overuse of application. The effectiveness of several materials as apple snail attractant baits was studied on screen house scale and field scale. Jackfruit and papayas are highly recommended to be used as attractant baits as well as cassava leaves and water spinach. Most of the snails were found attached to the materials either to feed or for shelter. All these type of attractant baits can be used to gather and collect apple snails in rice fields especially before the broadcasting stage of the rice seeds. The use of attractant baits also is seen as an important component of integrated management of the apple snail. © 2014 Penerbit UTM Press. All rights reserved.

In present study, 26 microbes consisted of 11 fungal isolates and 16 bacterial isolates were screened against blast disease pathogen (Pyricularia oryzae). All isolates were screened in vitro via dual culture bioassay. All fungal isolates collected were isolated from aerobic rice soils and the endophyic bacteria were isolated from the stem of healthy rice plants. Five isolates have been identified to be potential biocontrol agents as they recorded high PIRG (percentage inhibition of radial growth) values of more than 80%. Two isolates were identified as Trichoderma (F15 and F16) while the rest of them were bacteria isolates (I5, I6 and I16). 16S rDNA sequence analysis results showed that all three bacterial isolates were 100% similar to Paenibacillus polymyxa (Gene Bank assession number: GU332610.1). © 2014 Penerbit UTM Press.

Studies on effect of planting distance and seedling age on performance of local fragrant rice varieties, MRQ74 and MRQ76 were conducted in Ladang Merdeka Mulong, KADA during off season 2011 (OS 2011) and main season 2011/12 (MS 2011/12). Result shows that planting distance and seedling age influenced the yield and selected yield components. Recommended planting distance within row for both varieties regardless of cropping season was 18 cm while suitable seedling age for both varieties during OS 2011 and MS 2011/12 was 30 and 15 days, respectively. © 2014 Penerbit UTM Press.

The diversity of arthropod consists of pests and predators in rice fields were contribute to the biological control of crop pests at different stages of growth. The rice fields in Batang Lupar, Sarawak has diverse ecological conditions as well as presence of arthropod too. The study in MARDI research plot Batang Lupar in Sri Aman, Sarawak had been done on traditional rice varieties, Bubuk, Bali and Mamut by using sweeping net. The entire specimens were sorted out and classified into the smallest possible taxa. Statistical analysis were analysed by using Shanon-wiener Diversity Index, Evenness Shannon Index and Margalef Richness Index. A total of 272 individual arthropods had been collected and it consists of 7 order, 18 families and 23 species. Among of that 3 species are spiders, 9 species are insect pests and 11 species are insect predators. Analysis data for the diversity of arthropod has shown that there were no significantly different between three varieties, Bubuk, Bali and Mamut (P > 0.05). Besides that, diversity of the arthropod in Bali is higher than Bubuk and Mamut. © 2014 Penerbit UTM Press. All rights reserved.

Red rice is classified as specialty rice due to its coloured grain. Red colour that surrounded the outer layer of pericarp showed the existence of anthocyanin in red rice grain. However, heavy metal like arsenic in red rice plant become major concern in human health especially so in babies. This is because red rice normally used as a key raw material in the manufacture of infant cereals. In order to overcome this problem, study on effects of water regime on arsenic concentration in local red rice, MRM 16 was conducted during main season 2007/2008 and off season 2008. The water regimes tested were fully flooded, semi-aerobic and aerobic soil conditions. Result showed that arsenic concentration in the soil and grain was markedly highest when MRM 16 was cultivated under fully flooded in both seasons. However, concentration of arsenic in the soil and grain samples was the lower when the red rice was cultivated under semi-aerobic and aerobic soil conditions. Arsenic concentration in the soil and grain samples showed positive relationship. However, analysis of grain yield showed that the yield performance of MRM 16 was better when the soil was fully flooded or maintained semi-aerobically. © 2014 Penerbit UTM Press.
