“…Shyam and Singh (2015) and Singh et al (Singh et al 2016). Chauhan and Bajwa (2015) conducted experiment on rice in both dry and wet season and reported that the maximum reduction (87%) in C. rotundus density was accrued from the pendimethalin 1.0 kg/ha followed by bentazon at 1.0 kg/ha +cyhalofop at 0.100 kg/ha during the dry season. But, in wet season, the application of oxadiazon (at 0.50 kg/ha) followed by bentazon (at 1.0 kg/ha)+cyhalofop (at 0.100 kg./ha) resulted in maximum reduction in C. rotundus density (90%).…”

Weeds are eternal pest causing substantial losses of crop yields and quality, which are directly related to food security and safety, respectively. With existing crop protection measures, approximately one-third yield losses occur globally due to weeds, in which contribution of invasive/ noxious weeds is enormous. Invasive/noxious weeds have become a challenge in developing Asian countries, especially in India. These invasive/noxious weeds are widely distributed in all kinds of ecosystems. Invasive species cause losses of native biodiversity including species extinctions, and changes in hydrology and ecosystem function. The total annual cost of dealing with invasive species worldwide is estimated to be in the hundreds of billions of dollars, including costs of control, detrimental effects on human health and losses in agricultural production and ecosystem services. An estimated 20-30% of all introduced species worldwide cause a problem in a way or the other. The list of invasive alien weed species for India is well documented and available in public domain. There are 173 invasive alien species documented in India belonging to 117 genera and 44 families, which represents 1% of the total Indian flora. Tropical American region contributes to the maximum number (with 128 species or 74%) followed by tropical Africa (11%). Other regions, which contribute marginally, are Afghanistan, Australia, Brazil, East Indies, Europe, Madagascar, Mascarene Islands, Mediterranean, Mexico, Peru, Temperate South America, Tropical West Asia, West Indies and Western Europe. Different weed management practices are used for controlling these weeds both in cropped and non-cropped situations. Among these options, none is enough to completely control these weeds. Thus, integration of all these weed management tools is needed to be done. Considering the extent of yield losses caused by these noxious weeds, a comprehensive, effective and well adoptable technology is urgently needed to overcome these challenges. This review article is based upon the most striking management approach for the noxious weeds. It also emphasizes the relevance of future research aspects, such as early detection tool by adopting satellite based remote sensing, application of biotechnological tools like development of herbicide resistant crops, development of new herbicides molecules, enforcement of strong legislation and research on alternate approaches like weeds use for industry (making paper, herbal medicine and bio-fuel) to ensure higher income and livelihood security of farmers.

“…Rottboellia cochinchinensis competition during the entire sugarcane cropping season resulted in 43% less sucrose yield (Lencse and Griffin 1991). Sequential herbicide applications in dry direct-seeded rice (Oryza sativa L.) systems in the Philippines were necessary to maximize rice yield and reduce R. cochinchinensis biomass by 97% (Chauhan and Bajwa 2015).…”

Itchgrass [Rottboellia cochinchinensis (Lour.) W.D. Clayton] is among the most troublesome weeds in subtropical climates where sugarcane (Saccharum spp. interspecific hybrids) is cultivated. Two R. cochinchinensis biotypes commonly infest sugarcane in Louisiana. The Louisiana-1 biotype is daylength neutral, but Louisiana-2 flowered when daylength decreased to 13 h. Coupled with biotype diversity, seedling emergence has been reported to occur earlier in the growing season, as sugarcane emerged from winter dormancy. Both R. cochinchinensis biotypes were established in a common garden experiment in Louisiana during periods of sugarcane development and field preparation to simulate discontinuous emergence. Plant height and raceme production were recorded weekly for each biotype and establishment timing; aboveground biomass was harvested in autumn. Louisiana’s subtropical humid climate stimulated rapid plant growth that typically began in May and persisted through September. Without sugarcane competition, maximum R. cochinchinensis heights for Louisiana-1 and Louisiana-2 were 206 and 179 cm and growing degree days to 20-cm height in 2017 ranged from 546 to 832 and 865 to 1,160, respectively. Slower initial growth reported with Louisiana-2 would allow more time for growers to treat escaped plants with POST herbicides. Total raceme production, by autumn, was zero for Louisiana-2 established in June or later, but Louisiana-1 established in June produced up to 202 racemes. The present study demonstrated the importance of managing the Louisiana-2 biotype in March and April to limit seed production, but fields infested with Louisiana-1 were at greater risk for potential crop yield loss, because plants produced high quantities of seed when established over a wide period of time.
