In the United States, corn and soybean are among the most important crops, comprising 36.0 and 36.2 million hectares, respectively, in 2018, which was 55.5% of total area planted to principal crops (NASS-USDA, 2018). Since these crops cover such a large area, identifying management practices in corn and soybean production that promote sustainability (productivity over time while conserving natural resources) is an important goal. Nematodes play an important role in sustainability because

Stunt nematodes (Tylenchorhynchus spp.) are important plant parasitic nematodes that feed on a wide range of economic hosts. A survey of plant parasitic nematodes was performed in corn fields in May 2019, finding corn seedlings with symptoms like yellow leaves, dwarf plants and death plants in the field (N 37°07′36″, E 102°54′08″) of Baiyin City, Gansu Province, China. The rhizosphere soil samples and roots of diseased plants were collected. Each soil sample was about 1 kg consisted of over 20

the results herein. Egg masses were picked and put in water to release second-stage juveniles and males, whereas additional single egg masses were used to inoculate potted tomatoes (Solanum lycopersicum L.). In two cases of the corn (Zea mays L.) samples where mature egg masses were not found in galled roots, the original soil from the rhizosphere was used to fill pots (1,000 cm3) to which tomatoes were planted. After a 50 day growing period in a growth room, at 23–26 °C and 16 hr photoperiod

-susceptible soybean with non-host and SCN-resistant cultivars is considered the best method to manage SCN (Niblack and Chen, 2004; Niblack, 2005).
The beneficial effects of rotation of corn and soybean have been studied extensively, and in general, rotation increases the yields of both corn and soybean crops (Crookston et al., 1991). However, mechanisms of crop rotation are not fully understood. Suppression of pests and pathogens, including plant-parasitic nematodes, is probably one of the beneficial

According to the USDA’s National Agricultural Statistics Service (NASS), corn was the largest crop in America in 2019 with 91.7 million acres planted (USDA, National Agricultural Statistics Service, 2019a). Corn was also the most planted crop in South Carolina, with 380,000 acres planted in 2019 (USDA, National Agricultural Statistics Service, 2019b). Corn has many known pests and the most common nematodes affecting this valuable crop are spiral and root-lesion nematodes, followed by dagger

In search for local entomopathogenic nematode (EPN) species as a biological control agent of lepidopterous insect pests of corn, a survey for EPN in the major islands in the Philippines was conducted. Seven EPN populations from 279 soil samples were isolated using Ostrinia furnacalis, the key target insect pest of corn in the country, as bait. Analysis of the ITS1-5.8S-ITS2 ribosomal DNA sequence revealed the presence of Steinernema abbasi, Steinernema minutum, Steinernema tami, and

et al., 2021). In this manuscript, we describe a second of those undescribed species, previously referred to as Pratylenchus sp. 2 in Ozbayrak et al. (2019), herein described as Pratylenchus smoliki n. sp. The new species has been collected from two Great Plains States: Kansas and Nebraska. All positive collections were obtained from fields in a corn-soybean rotation. Notably P. smoliki n. sp. reproduces sexually and males make up approximately 30% of the adult population.

P. scribneri Steiner in Sherbakoff & Stanley, 1943 is primarily associated with agronomic crops such as potatoes (Brown et al., 1980; Yan et al., 2015), corn, and reportedly soybeans (Reboish and Golden, 1985).

corn cobs, when compared to monocomponent media. Although the process of lyophilization reduced the survival rate by 50–60%, the actual number of viable cells in obtained biopreparations remained relatively high (0.58 × 108 – 1.68 × 108 CFU/g dm). The studied strains in the preserved biopreparations were characterized by a high growth rate, as evaluated in microcultures using the Bioscreen C system.

For the nutrient concentration experiment, we evaluated the base medium versus a modified base medium containing all the components, but with 33 concentrations of yeast extract (6.9%), egg yolk (3.75%), and corn oil (12%). The nematodes and bacteria were cultured in 150-ml Erlenmeyer flasks containing 50 ml of liquid medium at (258C) and 180 rpm on a rotary

Phosphorus is a major essential macronutrient for plant growth, and most of the phosphorus in soil remains in insoluble form. Highly efficient phosphate-solubilizing bacteria can be used to increase phosphorus in the plant rhizosphere. In this study, 13 isolates were obtained from waste mushroom residues, which were composed of cotton seed hulls, corn cob, biogas residues, and wood flour. NBRIP solid medium was used for isolation according to the dissolved phosphorus halo. Eight isolates

Handoo, 2018; Subbotin and Skantar, 2018). Vittatidera zeaphila (Bernard et al., 2010), the goose grass cyst nematode, was first described from Obion County, Tennessee, USA, parasitizing corn and goosegrass. Later, host range studies and potential sources of resistance to V. zeaphila were published by Donald et al. (2012). In the summer of 2016, a field of corn (Zea mays) in Spencer County, Indiana was observed with heavily stunted plants, and from the affected roots a large number of cysts were

White grubs of Phyllophaga spp. (Coleoptera: Scarabaeidae) are the principal soil-living pests in corn production (Zea mays), affecting seed quality and yield (Jackson and Klein, 2006). In corn fields of the central valleys of Oaxaca, Mexico, one of the most abundant species is P. vetula (Horn), which causes yield loses up to 50% depending on plant stand losses (Ruiz-Vega et al., 2003). In Central Mexico, a yield loss of 500 to 1,400 kg.ha−1 is expected (Villalobos, 1992). However, the use of

Plant roots were abbreviated and final population density of P. minor was 2,856 ± 104 per pot (285 nematodes/100 cm3 of soil) confirming the nematode parasitism on onion. To our knowledge, this is the first report of P. minor parasitizing onion in Georgia. Stubby-root nematode (Paratrichodorus sp.) has already been reported on corn, St
