“…In annual crops, it is impossible to apply products with potential resistance inducer prior to nematode infection, which is already present in the soil at the time of germination. However, such products can decrease the feeding sites in subsequent life cycles, thereby decreasing the final nematode population (Silva et al 2004;Puerari et al 2013Puerari et al , 2015.

Silicates have the potential to induce disease resistance in plants. Induction of nematode resistance usually results from paralysis of nurse cell development or activation of the hypersensitivity response. This study aimed to evaluate the effects of silicon (Si) treatment on the penetration and development of Meloidogyne javanica in various crops. The experiment was set up in a randomized (3 × 4) + 1 factorial design, with 3 Si sources (Silifort®, Rocksil® and wollastonite), 4 crops (maize, rice, common bean and soybean) and 1 treatment control (distilled water). The Si treatments included adding wollastonite to the soil 10 days prior to seedling transplantation, or spraying with solutions of Silifort® or Rocksil®, 2 days after seedlings transplantation. Twelve days after transplantation, the plants were inoculated with 1000 eggs and eventual second‐stage juveniles (J2) of M. javanica. At 3, 8, 13 and 18 days after inoculation (DAI), the plants were harvested and nematode penetration evaluated by optical microscopy. All Si treatments adversely affected development of M. javanica in soybean, common bean and rice and reduced nematode penetration of rice roots. Silifort® and wollastonite reduced nematode penetration in common bean and soybean roots, respectively. However, none of the Si treatments influenced the variables analysed in maize. The results of this study illustrate the potential of Si treatment to control M. javanica parasitism in plants.

“…The GF427 isolate was more efficient when it was used in association with Ecolife ™ and AgroMos ™ , whereas the GF422 isolate was efficient in association with Ecolife ™ , only. Ecolife ™ is a product composed of citrus biomass and it can promote the production of phytoalexins (Motoyama, Schwan, Stangarlin, Fiori‐Tutida, & Scapim, ), whose efficiency in nematode control has been proven in other studies (Puerari et al., ), including in the handling of P. brachyurus (Puerari et al., ). AgroMos ™ , in turn, has not been investigated for nematode control; however, it showed promising results in the control of some fungi through resistance induction (Costa et al., ).…”

“…These microorganisms show different biochemical routes but similar phenotypic results. In addition, both the SAR and the ISR activators show promising potential for nematode control (Puerari, Dias‐Arieira, Cardoso, Hernandes, & Brito, ; Puerari et al., ; Sahebani & Hadavi, ).…”

Trichoderma spp. is a fungus with nematode control potential; however, its potential to control the root lesion nematode Pratylenchus brachyurus remains poorly studied.Thus, the aim of this study was to select Trichoderma spp. isolates and assess their ability to control P. brachyurus in soybean crops. Different experiments were conducted aiming at selecting isolates, assessing whether they were able to reduce nematode penetration in plants or cause mortality in vitro, and whether they were able to induce resistance in soybean, as well as at studying the possibility of using the selected isolates associated with resistance inducers (acibenzolar-S-methyl, Ecolife™ and AgroMos™). The selection experiment found three isolates showing satisfactory results, namely GF422, GF425 and GF427; the GF362 isolate was assessed in the subsequent experiments. These four isolates reduced P. brachyurus penetration in soybean roots and promoted nematode mortality in vitro. Increased total protein and catalase activity were recorded, mainly in the 72-hr assessments. Overall, the protein production was different between isolates. The best results were found in the combination between the GF362 isolate and the three resistance inducers, between GF427 and Ecolife™, between GF427 and AgroMos™ and between GF422 and Ecolife™.
