Non-chemical approaches to combat various pests and pathogens in agriculture including plant-parasitic nematodes are desirable as they are safer to humans and the environment. However, use of chemical fumigants, especially combinations of 1,3-D and chloropicrin are the standard practice in Florida tomato (Solanum Lycopersicon L.) fields to combat the problem of both RKN and soilborne pathogens (Santos et al., 2006; Minuto et al., 2006; Desaeger et al. 2017). When available, host resistance is

Tomato plants are among the world’s most cultivated crops and they are cultivated by both smallholder and commercial farmers in the Kingdom of Eswatini (FAO, 2012). Tomatoes are targeted by a vast number of insect pests and diseases including bacterial wilt (Ralstonia solanacearum), fusarium wilt (Fusarium oxysporum) and tomato leaf miner, Tuta absoluta (Lepidoptera: Gelechiidae). Tomato leaf miner is one of the most consequential lepidopteran pests that affect tomato plants (Husin, 2017

Three highest phosphate-dissolving bacterial isolates, namely, M01, M04, and M11, were evaluated for their beneficial effects on the early growth of tomato plants (Solanum lycopersicum L. Wanza 15). Strains M01, M04, and M11 significantly increased the shoot dry weight by 30.5%, 32.6%, and 26.2%, and root dry weight by 27.1%, 33.1%, and 25.6%, respectively.

The production of tomato (Solanum lycopersicum) is a very important industry in the United States with 10 billion kg tomatoes worth $1.6 billion United States dollars (USD) produced in 2019 (USDA-NASS, 2020). Florida produces 54% of fresh market tomatoes, an industry that produced 646 million kg worth $705 million (USD) nationwide in 2019 (USDA-NASS, 2020).

Root-knot nematodes (RKNs; Meloidogyne spp.) are sedentary endoparasitic nematodes that can infect a wide range of plant species worldwide, which results in approximately $70 billion in crop losses annually (Caboni et al., 2012). Meloidogyne spp. is ranked within the top 10 most economically devastating plant-parasitic nematodes, with Meloidogyne incognita, M. arenaria, M. hapla, and M. javanica as the four major crop-damaging species (Jones et al., 2013). In tomato, yield loss due to RKNs

At the seedling stage, foliage of each crop was sprayed with fluensulfone at 3, 6, and 12 g a.i./liter, oxamyl at 4.8 g a.i./liter, or water (nontreated control). Each plant was inoculated with Meloidogyne incognita juveniles 2 d after treatment. There were six replications per treatment and the

Nematodes are important parasites of crops. The economic losses caused by nematodes worldwide exceed 157 billion US dollars annually (Abad et al., 2008). Root-knot nematodes have a wide host range and are especially harmful to plants in the Cucurbitaceae and Solanaceae (Nicol et al., 2011). Tomato is extensively cultivated worldwide and highly susceptible. When the southern root-knot nematode (RKN) Meloidogyne incognita infects tomato, the second-stage juveniles (J2) penetrate young roots

The following work was initiated to determine the scope of application methodology and fumigant combinations for increasing efficacy of 1,3-dichloropropene (1,3-D) and metam sodium for management of root-knot nematodes (Meloidogyne spp.) in Florida. A series of five experiments were set up during spring and fall seasons to evaluate the potential of different fumigants, alone or in combination, in polyethylene film tomato production.

In experiments in which 10,000 nematode eggs were inoculated per plant, reductions in the number of eggs after 12 months were seen in three of four treatments in banana plants, reaching 34% for P.chlamydosporia var. catenulata. No significant reductions were seen in tomato plants after 3 mon. In another experiment with tomato plants using either P. chlamydosporia var. catenulata or P. lilacinum, the number of eggs was reduced by 34% and 44%, respectively

Multiple management strategies such as use of organic amendments, soil solarization, and nematicide application were also adopted to protect tomato plants against the Meloidogyne species (Terefe et al., 2009). Among these strategies, nematicides were successful up to certain extent, but they were very expensive and led to soil pollution problems.

The cryptic behavior, quick reproduction, and ability to develop resistance to insecticides make them a challenging pest (Gouli et al., 2008). Similarly, T. absoluta is the most serious insect pest of tomato grown in greenhouses or in the field, widely distributed in America, Europe, Africa, the Middle East, and

The tomato (Solanum lycopersicum L.) is one of the most cultivated oleraceous in Brazil, with a total area of 54,051 hectares and a production of 3,472.55 tons, with the states of São Paulo and Goiás being the largest producers (IBGE, 2016). In view of the socioeconomic importance of the crop and the need for controlled environmental conditions for cultivation, the tomato plants were grown in a protected environment, allowing an increase in production. However, it favored the development of

nematodes, especially root-knot nematodes (Meloidogyne spp.), are worldwide an extremely important limiting factor in vegetable production (Hallmann and Meressa, 2018).
Tomato (Solanum lycopersicon L.) is one of the most common vegetables grown in SA (FAO, 2017). Tomato can be infected by a wide variety of plant-parasitic nematodes but predominantly by root-knot nematodes which can cause significant yield losses (Jones et al., 2017).

The nematode was given the common name peach root-knot nematode. Further studies have shown that several other horticultural crops, e.g. tomato (Solanum lycopersicum) (Brito et al., 2015; Stanley et al., 2009), are hosts for this root-knot nematode species, while marigold (Tagetes spp.) was reported as a nonhost (Kokalis-Burelle and Nyczepir
