Volatile compounds as potential bio-fumigants against plant-parasitic nematodes – a mini review

Plant-parasitic nematodes (PPNs) are one of the major constraints to crop production, and especially in high-value vegetable and fruit crops, they can cause significant economic yield loss, estimated to be more than US$100 billion annually (Bernard et al., 2017). Chemical soil fumigants have been in use for more than a century now, and remain the standard practice in many crops, especially fruits and vegetables. Although many of the early fumigants have been banned, the ones that have managed

Nematicide influence on cotton yield and plant-parasitic nematodes in conventional and sod-based crop rotation

, stunting, and chlorosis (Lawrence and McLean, 2001; Blasingame et al., 2002; Robinson, 2007). Rotating to a non-host crop may provide short-term suppression of plant-parasitic nematodes in cotton production (Starr et al., 2002). For instance, crop rotation to a non-host like peanut (Arachis hypogaea) or corn (Zea mays) is an effective means to manage RN (Moore and Lawrence, 2012). Rotation to a non-host for one or more years can reduce RN populations below economic thresholds into the subsequent cotton

Plant-parasitic nematodes associated with sugarcane in Kilimanjaro, Tanzania

despite the fact that plant-parasitic nematodes (PPN) can damage roots and reduce the length of cane stalks leading to sugarcane yield loss (Berry et al., 2008). Several studies have uncovered PPN diversity in sugarcane fields in countries such as Mauritius (Williams, 1960a, b), India (Sundararaj and Mehta, 1993), Kenya (Chirchir et al., 2008, Steven et al., 2014), South Africa (Berry et al., 2017), and Brazil (Noronha et al., 2017), revealing the most common PPN genera associated with sugarcane as

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

Plant-parasitic nematodes are important agricultural pests and often cause serious crop losses. Novel, environmental friendly nematicides are urgently needed because of the harmful effects of some existing nematicides on human health. 5-Aminolevulinic acid (ALA) was reported as a potential biodegradable herbicide, insecticide, or plant-growth promoting agent. Lack of information on ALA against plant-parasitic nematodes prompted this investigation to determine the effects of ALA on Meloidogyne

Diversity and seasonal fluctuation of tylenchid plant-parasitic nematodes in association with alfalfa in the Kerman Province (Iran)

Worldwide, alfalfa (Medicago sativa L.), a flowering plant belonging to the family Fabaceae, is cultivated as a forage crop (Tucak et al., 2008). It is the most important forage crop in Iran due to its superior feeding value for cattle, which is the main meat/protein food source (Tucak et al., 2008). The genus Medicago comprises many species, with up to 23 being cultivated in Iran (Ghanavati et al., 2007). A wide range of plant-parasitic nematodes have been associated with alfalfa crops in

The impact of chemical nematicides on entomopathogenic nematode survival and infectivity

Plant parasitic nematodes (PPNs) are problematic soil dwelling pests. They attack and cause severe mechanical and physiological damage to plant roots as ecto- and endo-parasites as they feed on the sap and tissues with their stylet mouthparts. Subsequent effects include negative impact on plant growth and yield and may lead to plant death due to the PPNs (Atkinson et al., 2012; Forghani and Hajihassani, 2020; McCarter, 2009). PPNs feeding activity may also lead to secondary infections by other

is a common weed in agronomic crops and is particularly important because its seeds contain animal toxins (Furlan et al., 2012). Weeds often serve as alternative hosts to plant-parasitic nematodes, thereby increasing their incidence and severity. In addition, they reduce the efficacy of nematode management tactics. For example, nutsedges and plant-parasitic nematodes are two of the most common soilborne pest problems in Florida vegetable production and often occur concomitantly (Rich et al., 2003

The reproductive strategy of the pinewood nematode (PWN), Bursaphelenchus xylophilus, is sexual amphimictic and oviparous. The incidence of intrauterine egg development and hatching in plant-parasitic nematodes is not a very common phenomenon. During the process of maintaining and breeding a B. xylophilus population isolated in Spain under laboratory conditions, evidence of matricidal hatching was observed. This is the first described case of this phenomenon in this species.

For plant-parasitic nematodes (hereafter PPNs), they are obligately tied to the presence and relative abundance of host plants, but like other nematodes, their relative abundances may be influenced by soil properties such as the relative amounts of sand, slit, and clay (Van Gundy, 1985). For example, high populations densities of Meloidogyne spp. are commonly found in sandy soils over those soils with a large percentage of clay (Prot and Gundy, 1981

Recently, the presence of tropical nematodes has been reported from several Mediterranean or more southern European countries (Wesemael et al., 2011; EPPO, 2019). However, tropical nematodes do not yet pose a problem in the more northern parts of Europe, including Belgium. According to Bebber et al. (2013), there is clear evidence of a general, climate change-driven, poleward migration of pests and plant pathogens, a movement that can include tropical plant-parasitic nematodes. Interestingly

Temporal expression patterns of Pasteuria spp. sporulation genes

Some of the obligate, endoparasitic, spore-forming species of the bacteria Pasteuria spp. are antagonistic to plant parasitic nematodes. Pasteuria spp. is highly host specific; not all isolates of a given species will adhere to all phytoparasitic nematodes, and not all the endospores that adhere will germinate and infect the nematode (Mohan et al., 2012). Host specificity remains an essential barriers in deploying Pasteuria penetrans as a successful biological agent to combat agriculturally

Examples of genera known to parasitize turfgrass in the United States include Belonolaimus longicaudatus, Rau (sting nematode), Criconemoides spp. (ring nematode), Helicotylenchus spp. (spiral nematode), Hoplolaimus spp., Cobb (lance nematode), and Meloidogyne spp. (root-knot nematode) (Sikora et al

Spiral nematodes (Helicotylenchus spp.) are common plant-parasitic nematodes in fields of many crops. In June 2015, two soil samples were collected from a soybean field in Richland County, ND. Nematodes were extracted from soil using the sugar centrifugal flotation method ( Jenkins, 1964). Plant-parasitic nematodes were identified to genus based on morphological features and counted. Both samples contained spiral nematodes from 1,500 to 3,300 per kilogram of soil. In June and August
