Learn about grasses, sedge weeds, and broad-loaved weeds commonly infesting rice fields in Asia. Main weeds of rice in Asia - IRRI Rice Knowledge Bank Country Specific.
Basic requirements Rice is mainly grown in warmer regions as the plants will not grow at temperatures below 10°C. Rice is considered to be a semi-aquatic annual grass and is commonly grown in paddies in wetlands or under shallow water. Several new methods of propagating rice have been developed which allow rice to be cultivated in less conventional areas e.g.
drought resistant varieties are. Average predicted annual yield losses caused b y pests and diseases in South and Southeast Asia. Fig. Total predicted rice production losses f or intensive irrigated double- or triple-rice systems.
The attacked plants have a dark brown colour as if they got burned. Defoliators; Plenty of insects (Lepidoptera, Orthoptera, and Coleoptera), visit rice leaves in order to get fed. Insects that attack the grains; Oebalus pugnax, known as the rice stink bug attack immature plants and feed on their grain.

WHY. Experiments with the intensive use of pesticides has determined that the yield potential of rice varieties in Asia is about 10 t/ha. 4 One recent Study estimated that between and million tons of grain are lost yearly to insects, diseases, and weeds in rice fields in tropical Asia.
14 The mean region-wide rice yield loss due to pests was. Farmers lose an estimated average of 37% of their rice crop to pests and diseases every year. In addition to good crop management, timely and accurate diagnosis can significantly reduce losses.

It also contains a quick guide to the potential industry threats. South Asia produces slightly above million tons of rice (% of global production) on 60 million hectares (% of the global area).
India and Bangladesh are the major rice-growing countries. An identification guide of upland rice weeds with information on weed biology and management in South and South-East Asia is presented. Subjects include distribution, biology, ecology, and weed control.
Colour photographs show these weeds at different growth stages: (1) seed; (2) seedling; (3) flower; and (4) flowering plant. The genera are: Mollugo, Trianthema, Amaranthus, Celosia, Centella. Weed growth is affected by many cultural practices. Weeds also harbor, are hosts or sources of food for insect pests, diseases and other pests, as well as the natural enemies of these pests.
Control or failure to control weeds may have positive or negative effects on other rice pests. Some of these interactions are discussed in this paper. The Asia-Pacific Region has the resilience to meet its future demand and remain a net exporter of rice, provided concerted efforts are continued with greater vigor and thrust.
The trade globalization provided by GATT, WTO and Rice pests, and geographic comparative advantages of producing a crop, can provide major incentive for farmers to strive.
The book by Fröhlich is written in German language and contains a key to major rice pests and diseases based on signs of damage as well as some information on losses (see also chapter 4). Oerke & al.

The high susceptibility of hybrid rice to disease is likely to foster further dependence on agrochemicals. 35 In this sense, hybrid rice presents a tremendous opportunity for pesticide companies, which are reeling from market saturation in the North and anxious to expand sales in Asia.
For similar reasons, it creates new markets for their. yield and also encourage pests and diseases. * Likewise, in strungly acid sulfate soils the costs of reducing their acidity are a limiting factor.
The biological factors of the environment -- ro dents, insects, diseases, weeds, soil fertility - severely limit rice production in many areas. Several socioeconomic factors, such as high cost. MAJOR PESTS AND DISEASES. Overview. Many insect and mites attack trees in Asia.
Although some affect production in nearly all locations, many others are of only local significance. Relatively few species cause significant crop loss in their own right, and are only a problem when the population exceeds damaging thresholds.

Since its earliest days in Southeast Asia, rice has grown throughout the region and the world, with varieties farmed in Africa, South America and the U.S.
Integrated weed management practices in rice include: Land preparation: Thorough land preparation can significantly decrease the incidence of weeds in rice by destroying all weeds and weed seeds to provide weed-free conditions at the time of planting, and providing a good environment for rapid growth of rice seedlings.
To satisfy a growing demand for food, global agricultural production must increase by 70% by However, pests and crop diseases put global food supplies at risk. Worldwide, yield losses caused by pests and diseases are estimated to average % in wheat, % in rice, % in maize, % in potato, and % in soybean ([ 1 ]); these crops account for half of the global human.
Southeast Asia, the world’s dominant rice export region, has an important role in determining world rice prices and food security in regions that depend on rice imports, such as Sub-Saharan Africa.
Rice, after wheat, is the world’s most consumed food grain, with global consumption reaching million metric tons in. Taro probably originated in southeast Asia or southern Asia.
It is believed to be one of the earliest crops to be domesticated with several centers of domestication, one being in New Guinea. Early Pacific voyagers carried taro with them throughout the Pacific. Taro is still one of the most important staple food items in the region.
