Abstract Nematodes stand out among the main soya bean yield limiting factors due to limitations in control methods, mainly when they are applied alone. Given need of finding new techniques, aim this study was assess efficiency products based on biological agents and nutrients or showing potential induce resistance for Pratylenchus brachyurus Meloidogyne javanica plants. The experiments were conducted a greenhouse; nine treatments with six repetitions each nematode assessed two distinct...
ABSTRACT Root lesion nematodes limit the productivity of several crops economic importance, requiring alternatives for their management. Resistance inducers activate enzymes involved in defense mechanisms and micronutrients can influence this process by acting as enzymatic cofactors. Thus, objective study was to evaluate effect foliar application a commercial organomineral fertilizer its association or not with zinc (Zn) manganese (Mn) on Pratylenchus brachyurus suppression soybean plant...
ABSTRACT Root-knot nematodes (Meloidogyne spp.) cause severe damage to tomato crop. This study aimed investigate the biocontrol potential of arbuscular mycorrhizal fungus Rhizophagus clarus compared with that fungi Trichoderma harzianum and Pochonia chlamydosporia against Meloidogyne javanica in assess activity defense-related enzymes roots. Three experiments were carried out evaluate colonization, nematode penetration, development, reproduction, plant growth, enzyme We observed R....
Antagonistic and non-host plants are some of the main strategies for nematode control, but reaction several plant species to these parasites remains be investigated. This study aimed evaluate buckwheat Pratylenchus brachyurus Meloidogyne javanica assess effect aqueous extract on P. M. mortality hatching. Experiments were conducted under greenhouse laboratory conditions. Treatments consisted 'IPR-92 Altar' soybean 'M6410 IPRO' inoculated with different levels or according each experiment....
Ginger is a medicinal plant known for its aromatic, antioxidant, and pharmacological properties. This study aimed to examine the vegetative growth biochemical profile of ginger exposed Meloidogyne javanica at different initial inoculum levels. The experiment was conducted in greenhouse using completely randomized design. Treatments comprised 0, 2000, 4000, 6000, 8000, 10,000 eggs M. eight replications per treatment. At 70 days after inoculation, plants were harvested evaluated nematode...
Nanoparticles of silicon (Si) and titanium (Ti), typically considered non-essential elements, show promise in enhancing fertilizer efficiency crop performance. This study aimed to synthesize these nanoparticles evaluate their potential as seed treatments for maize. Using the sol-gel method, Si Ti were produced extensively characterized through techniques like X-ray diffractometry, transmission electron microscopy, surface area analysis, Fourier-transform infrared spectroscopy. Their effects...
This study aimed to investigate the efficacy of Ascophyllum nodosum extract, in combination or not with biocontrol agents, management Meloidogyne javanica soybean, assess treatment effects on soil biological activity, and determine total phenolic content extract. The experiment was conducted according a 5 × 2 factorial design, three agents (Bacillus methylotrophicus, Pochonia chlamydosporia, Trichoderma harzianum), chemical nematicide (abamectin, positive control), an untreated (negative)...
Nematodes of the Meloidogyne genus are among main limiting factors world agricultural productivity. Its management is quite complex and alternative methods such as use extracts have been widely studied. This study aimed to evaluate penetration development M. javanica in soybean (Glycine max (L.) Merr.) treated with Ascophyllum nodosum extract assess this algal product its nutrient components nematode management. Experiment 1 comprised five sampling times (5, 10, 15, 20, 25 d after...
Abstract This study aimed to investigate the effects of crop rotation with Macrotyloma axillare ‘Java’, Crotalaria spectabilis and ochroleuca combined green manure application or biological treatment, on control Meloidogyne javanica in soybean. An initial greenhouse was conducted a 4 × 2 factorial design, four crops ( M . C , soybean) presence absence manure. A second carried out using 5 five biocontrol treatments Pochonia chlamydosporia Purpureocillium lilacinum + Trichoderma harzianum...
Elicitors of plant resistance are compounds that activate enzymatic processes involved in defense. Micronutrients also play an important role responses against pathogens because they function as enzyme cofactors. Despite their well-known benefits, elicitors and micronutrients have been little investigated nematode control. This study aimed to assess the effects Agro-Mos® (a commercial biostimulant) (Zn Mn), alone combined, on soybean inoculated with Meloidogyne javanica. Seeds were sown...
Abstract In an integrated nematode management system, the best results are generally obtained by rotating crops with resistant plants, antagonists, or bad hosts of parasites. Some reports indicate that Stylosanthes spp. have potential to control nematodes. Thus, this study aimed assess reaction 'Campo Grande' Pratylenchus brachyurus and Meloidogyne javanica penetration reproduction at different inoculum levels examine histopathology histochemistry parasitized plants. did not prevent P. in...
This study aimed to examine the relationship between Macrotyloma axillare 'Java' and Meloidogyne javanica at different levels of nematode inoculum, assess activity plant defence enzymes in presence nematodes. In Experiment 1, soybean (control) were inoculated with 300 8000 eggs + second-stage juveniles (J2) M. two periods (Trials 1 2). To confirm results, a third trial was conducted using 1000 4000 J2 per plant. 2, β-1,3-glucanase (GLU), phenylalanine ammonia-lyase (PAL), peroxidase (POX),...
