“…This carryover effect to conventional rice was reported significantly more by respondents from IADA BLS 560 Dilipkumar et al: Weedy rice survey in Malaysia (P < 0.05) than by those from MADA and KADA (Table 3). Dissipation studies conducted in Malaysia showed that the residual effect of OnDuty TM in soil remained until 126 d after application under glasshouse conditions (Ibrahim et al 2017) and 85 d after application under field conditions (Bzour et al 2019). However, the persistence and leaching of IMI herbicides in soil are influenced by several factors such as the physicochemical properties of the soil, organic matter, soil pH, photodegradation, chemical degradation, microbial activity, and the hydrolysis process (Refatti et al 2017).…”

Survey on weedy rice (Oryza spp.) management practice and adoption of Clearfield® rice technology in Peninsular Malaysia

A total of 452 rice farmers from three main granary areas of Muda Agricultural Development Authority (MADA), Kemubu Agricultural Development Authority (KADA), and Integrated Agricultural Development Area Barat Laut Selangor (IADA BLS) were surveyed in 2019. The goal was to determine farmers’ knowledge and management practices of weedy rice (Oryza sativa L.) as well as the adoption level of Clearfield® rice technology (CRT) in Malaysia. Most farmers (74%) were adept at recognizing O. sativa. The majority of farmers (77%) perceived transplanting and water seeding rice systems as the best options to manage O. sativa while only 10% of the farmers adopted CRT. Low adoption level of this technology was due to several constraints including high cost of the CRT package and occurrence of imidazolinone (IMI)-resistant O. sativa in their farms. Farmers from MADA and IADA BLS reported the occurrence of IMI O. sativa in their farms for more than nine planting seasons whereas those from KADA reported having resistant O. sativa for five to six planting seasons. The main factor contributing to the evolution of IMI-resistant O. sativa was ignorance about the technology and deliberate disregard of stewardship guidelines. The survey revealed that there is a need to increase awareness about CRT through training and educational program for proper adoption of this technology.

“…For instance, the introduction of the Clearfield® Production System (CPS) using Imidazolinone (imazapic and imazapyr) herbicide had been successful in reducing weedy rice population, and led to the eventual increase of rice production during the initial years of its introduction (Azmi, Azlan, Yim, George, & Chew, 2012). However, it has been reported that weedy rice had subsequently developed resistance toward Imidazolinone herbicides within 5 years of the CPS introduction (Bzour, Zuki, Mispan, Jodeh, & Latif, 2019; Dilipkumar, Burgos, Chuah, & Ismail, 2018; Engku et al, 2016; Jaafar, Juraimi, Hamdani, Kamaluddin, & Man, 2014). The gene flow from herbicide‐resistant rice varieties to weedy rice from natural hybridization (Engku et al, 2016; Ruzmi, Ahmad‐Hamdani, & Bakar, 2017) and spontaneous mutation (Dilipkumar et al, 2018) has been discussed as the potential contributors to weedy rice resistance in the country.…”

The dynamic changes in agricultural practices have negatively impacted rice cultivation resulting in serious weedy rice (Oryza sativa L.) infestations. In this study, field surveys were conducted at six granaries to evaluate the abundance, spatial‐distribution patterns, and morphological characteristics of weedy rice in Peninsular Malaysia. An average of 5.28 plants/m2 weedy rice density was recorded, with coverage area that ranged from 29% to 66% and occurrence at >67% frequency. Seed morphological characteristics identified the existence of at least 18 biotypes. A total of 134 weedy rice samples were characterized morphologically, and Principle Component Analysis results showed that these samples are highly diverse and are dispersed across Peninsular Malaysia. These genetically diverse reservoir of weedy rice characteristics present opportunities of exploitation in the future, especially through rice breeding and crop improvement. Weedy rice from Kelantan and Selangor displayed unique clusters in the PCA plot which suggest higher tendencies for environmental adaptation although the influencing factors have yet to be determined. Dispersion studies based on Lloyd patchiness index revealed that more than 50% of surveyed field blocks in five states displayed uniform distribution as opposed to cluster distribution observed in the remaining field blocks. These variations in dispersion suggested that farmers in Peninsular Malaysia employed inconsistent weedy rice management practices in every granary and farm block. Observation of weedy rice infestation pattern via spatial distribution suggested that weed management requires proper coordination of control efforts among farmers to ensure the degree of infestation is maintained under a controlled level.
