Nematicidal Activity of Fosthiazate Against Soybean Cyst Nematode Heterodera glycines

Soybean (Glycine max, Family Leguminosae) is widely grown worldwide due to its unique property of possessing high plant-based protein contents, lipid minerals, and vitamins (Olaoye and Ade-Omowaye, 2011). Soybean cyst nematode (SCN, Heterodera glycines) infection is the most serious disease affecting soybean production worldwide; this infection was reported for the first time in 1899 in Northeast China, since then, this nematode has been spread widely in various regions, including Asia, America

Active and inactive forms of biotin synthase occur in Heterodera glycines

The soybean cyst nematode (SCN), Heterodera glycines, is an obligate plant parasite that poses a serious threat to soybean production worldwide. It is the most damaging pest of soybean in the USA and is estimated to cause more yield loss than any other disease (Koenning and Wrather, 2010; Wrather et al., 2010; Allen et al., 2017). Yield losses are attributed to the fact that this nematode injects a complex mixture of proteins and metabolites into the plant root cells (Niblack et al., 2006) and

Identification of HG Types of Soybean Cyst Nematode Heterodera glycines and Resistance Screening on Soybean Genotypes in Northeast China

Soybean cyst nematode (SCN, Heterodera glycines Ichinohe) is a serious soybean pathogen worldwide. HG Type 0 had been a predominant SCN in Heilongjiang province, the largest soybean (Glycine max L.) producing region in China. Recently, increased virulence on resistant cultivars originally developed for resistance to HG Type 0 was observed in fields. In order to identify new cultivars resistant to local SCN populations, two soil samples were collected from two counties (Anda and Wuchang) in

A New Race (X12) of Soybean Cyst Nematode in China

The soybean cyst nematode (SCN), Heterodera glycines, is a serious economic threat to soybean-producing regions worldwide. A new SCN population (called race X12) was detected in Shanxi province, China. Race X12 could reproduce on all the indicator lines of both race and Heterodera glycines (HG) type tests. The average number of females on Lee68 (susceptible control) was 171.40 with the lowest Female Index (FI) 61.31 on PI88788 and the highest FI 117.32 on Pickett in the race test. The average

The effects of Meloidogyne incognita and Heterodera glycines on the yield and quality of edamame (Glycine max l.) in Arkansas

(Wrather and Koenning, 2003, 2006). Two nematodes of major concern for soybean production in Arkansas include the soybean cyst nematode (Heterodera glycines, Ichinoe) and the southern root-knot nematode (Meloidogyne incognita, Kofoid & White, Chitwood). Both nematodes have been historically present in Arkansas soybean and cotton fields (Kirkpatrick et al., 1992; Bateman et al., 2000; Walter and Barker, 1994; Tylka and Marett, 2014). A survey from 2018 identified that soybean cyst and root-knot nematode

Fungal communities associated with Heterodera glycines and their potential in biological control: a current update

The soybean cyst nematode (Heterodera glycines, SCN) was discovered as a significant pest of soybean in 1954 in North Carolina in the USA, and subsequently spread across a few counties in Arkansas, Missouri, Kentucky and Tennessee, as well as few other pockets in North Carolina (Winstead and Skotland, 1955). In 2014, bolstered by the increase in planting of soybean, the SCN has become a significant plant health issue all over the agrarian eastern continental United States as well as Hawaii and

Field and greenhouse evaluations of soil suppressiveness to Heterodera glycines in the Midwest corn-soybean production systems

Soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is widely distributed throughout most soybean producing regions in the world (Riggs, 2004). This nematode has become a major yield-limiting factor in soybean production and causes an estimated annual yield loss of about $1 billion in the USA (Koenning and Wrather, 2010). Crop rotation, cultural practices, resistant cultivars, and nematicides are employed to reduce soybean yield suppression caused by SCN. Particularly, rotation of SCN

Nematicidal Effects of 5-Aminolevulinic Acid on Plant-Parasitic Nematodes

incognita, Heterodera glycines, Pratylenchus coffeae, and Bursaphelenchus xylophilus. A series of in vitro assays and one greenhouse trial were conducted to examine the nematicidal effects of ALA. The results demonstrated that ALA exhibited a strong effect of suppression against the four nematodes tested. ALA also inhibited hatching of M. incognita and H. glycines. Results from the greenhouse experiment indicated that treatment of soil with 6.0 mM ALA significantly reduced the root-gall index (RGI) and

Swine manure application enriches the soil food web in corn and soybean production

management of plant-parasitic nematodes is necessary to optimize crop productivity (Grabau and Chen, 2016a, 2016b) and non-parasitic, free-living nematodes contribute to and are sensitive indicators of soil fertility and ecology (Bongers, 1990; Ferris et al., 2001). In particular, soybean cyst nematode (Heterodera glycines) is the major yield-limiting pest in soybean production (Koenning and Wrather, 2010). Additional strategies to manage this pest are needed because management relies on a narrow set of

Effect of Heterodera schachtii female age on susceptibility to three fungal hyperparasites in the genus Hyalorbilia

early juvenile stages were less susceptible. In cabbage root culture, DoUCR50 reduced the number of H. schachtii females with eggs by more than 95% and the number of eggs per female by almost 60% compared with females developing in culture without the fungus. Similarly, parasitism of Heterodera glycines by a sterile nematophagous fungus, ARF-L, was detected at early developmental stages after inoculation of soybean with nematode eggs and juveniles (Timper et al., 1999). Mycelial mats were observed
