“…This indicates that grafting on CM-334 is a control alternative to P. capsici in serrano chilli because none of the grafted plants showed wilting symptoms. Similar results have been obtained in poblano chilli (García-Rodriguez et al, 2010) and pepper (Duan et al, 2016).…”

Grafting is an alternative method of plant propagation used to prevent soil‐borne diseases. This technique can improve the development of plants and therefore improve fruit yield and quality; however, several studies report that when a plant is grafted, there may be compatibility problems and changes in the phenological pattern of the crop and fruit yield and quality with respect to non‐grafted plants. There are no reports in the literature on the behaviour of serrano chilli grafted on varieties resistant to Phytophthora capsici. In this study, we evaluated the phenological behaviour and response to inoculation with P. capsici in commercial serrano chilli (Camino Real, Harris Moran) grafted or not on CM‐334 as a strategy to explore the possibility of incorporating the use of grafts in the production systems of serrano chilli. The plants were grafted at 55–60 days and maintained for 13 days in a curing chamber for the acclimatization process. At 36 and 43 days after transplantation, they were inoculated with the pathogen (300,000 zoospores/plant). None of plants grafted and inoculated with the pathogen showed wilt symptoms. All plants not grafted and inoculated with P. capsici died. There was a significant reduction in the production of leaves and flowers in the grafted plants, in relation to the non‐inoculated and non‐grafted plants, as well as a temporary delay in the beginning of fruit production with respect to the non‐grafted plants, but this delay did not affect the overall yield of the crop.

“…Chilli (Capsicum spp.) is one of the most cultivated vegetables worldwide (Duan et al, 2016). The most important pathogen of this crop is Phytophtora capsici Leonian (Richins, Micheletto, & O′ Connell, 2010), which causes wilt and death.…”

“…Sacc. have been shown to be pathogenic (Celar, 2000;Dinget al, 2017;Duan et al, 2017;Hibar et al, 2006;Manici et al, 2003;Ramamoorthy et al, 2002;Steinkellner et al, 2008;Tewoldemedhin et al, 2011b;Yan et al, 2018;Zhu et al, 2016). And F. moniliforme have also been shown to be pathogenic on forest nurseries in Spain (Pinto et al, 2006), Sorghum in India, Maize in Iowa State (Da Silva, 2010), Scots pine seedlings in Palencia (Yang et al, 2012), Peach in California (Machon et al, 2006 and apple in China (Ju et al, 2014;Wang et al, 2018).…”

Apple replant disease (ARD) has been reported from all major fruit-growing regions of the world, and is often caused by biotic factors (pathogen fungi) and abiotic factors (phenolic compounds). In order to clarify the proteomic differences of Fusarium moniliforme under the action of phloridzin, and to explore the potential mechanism of F. moniliforme as the pathogen of ARD, the role of Fusarium spp in ARD was further clarified. In this paper, the quantitative proteomics method iTRAQ analysis technology was used to analyze the proteomic differences of F. moniliforme before and after phloridzin treatment. A total of 4535 proteins were detected, and 293 proteins were found with more than 1.2 times (P<0.05) differences. In-depth data analysis revealed that differentially expressed proteins were influenced a variety of cellular processes, particularly metabolic processes. Among these metabolic pathways, a total of 8 significantly enriched KEGG pathways were identified with at least 2 affiliated proteins with different abundance in conidia and mycelium. Functional pathway analysis indicated that 46 up-regulated proteins were mainly distributed in amino sugar, nucleotide sugar metabolism, glycolysis/ gluconeogenesis and phagosome pathways. The results deepened our understanding of the proteome in F. moniliforme in response to phloridzin inducers and provide a basis for further exploration for improving the efficiency of the fungi as biocontrol agents to control ARD.

“…The chili crop is susceptible to the pathogen Phytophthora capsici , which causes the disease known as chili wilt, which spreads through irrigation water and rain through oospores and zoospores . This pathogen causes losses in the world production of peppers that exceed US$10 million annually . The characteristic symptoms of this disease are delay in the growth or wilting of the plant, and characteristic brown or black coloration to the roots, stem and fruits …”

BACKGROUND: Hydrogels are materials with great potential in agricultural applications. Biodegradable hydrogels are used as preparations, for example to increase the substratum water capacity, and improve soil structure or agrochemical-controlled release. This work aimed to develop biodegradable hydrogels based on chitosan, gelatin and polyvinyl alcohol (PVA) for releasing inulin isolated from Dahlia tubers to induce protection in chili plants against Phytophthora capsici. The hydrogels were characterized by water absorption capacity, Fourier transform infrared (FTIR), scanning electron microscopy (SEM) and stereomicroscopy microscopy, and degradation capacity using the soil burial test with sterile and inoculated soil. RESULTS: This work demonstrated the ability of a fabrication process in the preparation of gelatin-chitosan-PVA hydrogelsfor potential agricultural applications. The hydrogels showed a dense, tridimensional, interconnected and reticulated structure that was more evident in the hydrogel loaded with inulin. The hydrogels showed a water absorption capacity of ≤12 times its mass. FTIR and light microscopy demonstrated that the hydrogels were biodegradable. The percentage of degradation of hydrogels in inoculated soil was higher than in sterile soil using the soil burial test. Hydrogel loaded with inulin was found to be capable of inducing resistance in chili plants against Phytophthora capsici. CONCLUSION:The hydrogels prepared for the described methodology have great potential for use in the agricultural sector as a reservoir for agrochemicals and inductors in plant resistance treatments. Furthermore, the hydrogels were proven to be biodegradable, offering a promising tool in crop protection. Surface morphology of hydrogelsThe hydrogels have a polyhedral irregular shape. Figure 5(a) shows that the surface morphologies of the hydrogels revealed the formation of a reticulate heterogeneous network. When the hydrogel was loaded with inulin and freeze-dried again, inulin aggregates between the macro channels of the structure [Fig. 5(b)]. Biodegradation test of the hydrogelThe degradation of the hydrogels (H and HI), that were buried in the sterile and inoculated soil were monitored after 7, 14, J Chem Technol Biotechnol 2019; 94: 3495-3504
