Control of the tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) larvae in laboratory using entomopathogenic nematodes from subtropical environment

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

Isolation and Characterization of Phosphate-Solubilizing Bacteria from Mushroom Residues and their Effect on Tomato Plant Growth Promotion

produced indole acetic acid (61.5%), and six isolates produced siderophores (46.2%). 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. Based on 16S rRNA gene sequence comparisons and

Meloidogyne incognita management by nematicides in tomato production

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). Meloidogyne incognita (southern root-knot nematode, SRKN) is a major pest in tomato production, and there are relatively few management

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

Nicotinamide adenine dinucleotide induced resistance against root-knot nematode Meloidogyne hapla is based on increased tomato basal defense

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

Mixtures of fluopyram and abamectin for management of Meloidogyne incognita in tomato

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

Effects of fluopyram and azadirachtin integration with sunn hemp on nematode communities in zucchini, tomato and sweet potato in Hawaii

Increasing food self-sufficiency is a critical objective for the State of Hawaii that imports 90% of its food from the global market (Department of Business Economic Development and Tourism DBEDT and Hawaii Department of Agriculture HDOA, State of Hawaii, 2012). Currently, the value of vegetables, melons, potatoes (Solanum tuberosum), and sweet potatoes (Ipomoea batatas) grown by local farmers is $85 million annually plus $6 million in greenhouse tomato sales in Hawaii (United States Department

Methyl Bromide Alternatives for Control of Root-knot Nematode (Meloidogyne spp.) in Tomato Production in Florida

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. The most promising chemical alternatives to methyl bromide, in

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

conditions can make the applied nematicide ineffective against nematodes. 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.

Two years of field trials conducted in a Meloidogyne incognita-infested field evaluated grafting and Paladin Pic-21 (dimethyl disulfide:chloropicrin [DMDS:Pic] 79:21) for root-knot nematode and weed control in tomato and melon. Tomato rootstocks evaluated were; ‘TX301’, ‘Multifort’, and ‘Aloha’. ‘Florida 47’ was the scion and the nongrafted control. A double crop of melon was planted into existing beds following tomato harvest. Melon

Gall and egg-mass indexes were obtained according to a 0–5 scale. Plants with a reproduction factor higher than 1.0 were classified as susceptible (S) and lower than 1.0 as resistant (R). Wheat and oat genotypes did not allow M. incognita and M. javanica reproduction, proving resistance to these organisms. Sorghum

Hatching and Mortality of Meloidogyne enterolobii Under the Interference of Entomopathogenic Nematodes In vitro

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
