Control of volunteer adzuki bean in soybean

Abstract

ABSTRACT, and imazethapyr applied PRE provided up to 6%, 24%, 14%, 8%, and 0% control, respectively at 8 weeks after emergence (WAE), while acifluorfen, fomesafen, bentazon, thifensulfuron-methyl, cloransulam-methyl, imazethapyr, and imazethapyr plus bentazon applied POST provided 2%, 2%, 5%, 34%, 6%, 4%, and 12% control, respectively at 8 weeks after application (WAA). Generally, with the aforementioned herbicides, soybean yield was equivalent to the weedy control and soybean grain contamination with adzuki bean seed was consistently above the 1% maximum threshold. Chlorimuron-ethyl and glyphosate applied POST provided up to 84% and 94% visual control at 8 WAA, respectively, decreased adzuki bean density, biomass, and seed production, and generally decreased soybean contamination with adzuki bean below the 1% threshold. The only herbicides evaluated in this study that controlled volunteer adzuki bean in soybean were chlorimuron-ethyl (9 g ai.ha

Genome sequencing of adzuki bean ( Vigna angularis ) provides insight into high starch and low fat accumulation and domestication

“…angularis) was domesticated in China ∼12,000 y ago (1) and is grown in more than 30 countries of the world, especially in East Asia (2,3). Adzuki bean seed is an important source of protein, starch, mineral elements, and vitamins (4,5).…”

Weed management in adzuki bean: a review

“…Seeds should be planted 2.5-3.8 cm deep, in rows spaced 60-90 cm apart (Hardman et al 1989;Hang et al 1993;HDC 2014). Each pod contains 4-12 wine-red seeds that measure 5-7.5 mm long and 4-5.5 mm wide; slightly smaller than a soybean seed (Duke 2012;Kramer et al 2012). In part, due to slow initial seed imbibition, adzuki bean seedlings emerge 10-20 d after sowing (Hardman et al 1989;Yoshida et al 1995).…”

“…The weedy persistence of transiently grown domesticated adzuki bean cultivars in Japan suggests an incomplete removal of seed dormancy, despite breeding efforts (Kaga et al 2008). Likewise, Ontario producers have observed volunteer adzuki bean up to 10 yr following production (Kramer et al 2012). While not tested in soil, Lumpkin and McClary (1994) reported that adzuki bean seed stored at 15% relative humidity and 14% seed moisture content retained 96% germination for 10 yr.…”

“…In corn production, volunteer adzuki bean can reduce yield by up to 43% (Kramer et al 2010). Volunteer populations are particularly disadvantageous for soybean growers as adzuki bean seeds vary only slightly in size and are thus difficult to remove from the harvested product (Duke 2012;Kramer et al 2012). In the case of identity preserved soybeans, contaminants exceeding 1% will cause high value product to be downgraded and the premium removed.…”

Discrimination of Adzuki Bean (Vigna angularis) Geographical Origin by Targeted and Non-Targeted Metabolite Profiling with Gas Chromatography Time-of-Flight Mass Spectrometry

“…The adzuki bean (Vigna angularis), which contains starch, nutritious proteins, and vitamins and has a sweet taste, has been used as an ingredient in traditional dessert foods, particularly in East Asian countries such as Korea, China, and Japan [1][2][3]. Adzuki beans have been extensively cultivated in more than 30 countries worldwide [4][5][6]. Additionally, international food trade has dramatically increased owing to the development of food storage and transportation technologies.…”
