“…Several crop species that had been sprayed with Phi and inoculated with different pathogens showed protection functions to the plants; such protection is related to the rapidly increased amounts of phytoalexin and ROS than untreated, infected plants ( Ramezani et al, 2017a ; Borza et al, 2019 ; Mohammadi et al, 2019 ). Cucumber plants infected with Pythium ultimum and treated with Phi-evidenced induction of antioxidant enzymes decreased ROS and alleviated damping-off symptoms ( Mofidnakhaei et al, 2016 ).…”

“…The low Phi activity in vitro indicates that the plant immune response is involved to a certain extent, so it is concluded that plants without a dynamic immune response are not protected by Phi ( Arfaoui et al, 2020 ). Based on a 2-year field experiment, Borza et al (2019) documented that a mixed-mode of Phi affects both plant defense and pathogen growth in vitro. However, the results were consistent with the site of Phi operation in Verticillium spp.…”

Phosphite (Phi) is a chemical analog of orthophosphate [HPO43−]. It is a systemic pesticide generally known to control the prevalence of oomycetes and soil-borne diseases such as Phytophthora, Pythium, and Plasmopora species. Phi can also control disease symptoms and the spread of pathogenic bacteria, fungi, and nematodes. Phi plays critical roles as a fungicide, pesticide, fertilizer, or biostimulator. Overall, Phi can alleviate the severity of the disease caused by oomycete, fungi, pathogenic bacteria, and nematodes (leave, stem, fruit, tuber, and root) in various plants (vegetables, fruits, crops, root/tuber crops, ornamental plants, and forests). Advance research in molecular, physiological, and biochemical approaches has approved the key role of Phi in enhancing crop growth, quantity, and quality of several plant species. Phi is chemically similar to orthophosphate, and inside the cells, it is likely to get involved in different features of phosphate metabolism in both plants and pathogens. In plants, a range of physiobiochemical alterations are induced by plant pathogen stress, which causes lowered photosynthesis activities, enzymatic activities, increased accumulation of reactive oxygen species (ROS), and modification in a large group of genes. To date, several attempts have been made to study plant-pathogen interactions with the intent to minimize the loss of crop productivity. Phi’s emerging function as a biostimulant in plants has boost plant yield and tolerance against various stress factors. This review discusses Phi-mediated biostimulant effects against biotic and abiotic stresses.

“…Indeed, Phi can be used a priming agent to trigger a wide range of plant defense functions against the pathogen. Recent work done by Wang-Pruski's group also indicated that Phi may be affective to other pathogens, including some Verticillium species [63]. Therefore, further study on Phi's mechanism may lead to its broader applications in agricultural production.…”

Potato late blight (Phytophtora infestans) is among the most severely damaging diseases of potato (Solanum tuberusom L.) worldwide, causing serious damages in potato leaves and tubers. In the present study, the effects of potassium phosphite (KPhi) applications on photosynthetic parameters, enzymatic and non-enzymatic antioxidant properties, hydrogen peroxide (H2O2) and malondialdehyde (MDA), total protein and total carbohydrate of potato leaves challenged with P. infestans pathogen were investigated. Potato leaves were sprayed five times with KPhi (0.5%) during the growing season prior to inoculation with P. infestans. The potato leaves were artificially infected by the LC06-44 pathogen isolate. The leaves were sampled at 0, 24, 48, 72 and 96 h after the infection for evaluations. P. infestans infection reduced chlorophyll (Chl) pigments contents, chlorophyll fluorescence, carotenoid (Car) and anthocyanin contents and increased the accumulation of H2O2 and MDA. Meanwhile, our result showed that KPhi treatment alleviated adverse effect of late blight in potato leaves. KPhi application also increased plant tolerance to the pathogen with improved photosynthetic parameters Chl a, b, total Chl, Car, and anthocyanin compare to controls. Moreover, the increased oxidative enzymes activity of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and ascorbate peroxidase (APx), and non-enzymatic substances such as phenolics, flavonoids and proline were found in KPhi treated plants, compared to untreated plants after inoculation. In addition, KPhi application followed by P. infestans infection also decreased the content of H2O2 and MDA, but increased the total protein and total carbohydrate contents in potato leaves. The consequence of current research indicated that KPhi played a vital role in pathogen tolerance, protecting the functions of photosynthetic apparatus by improved oxidative levels and physio-biochemical compounds in potato leaves.

“…In the case of potatoes, the application of phosphites limited the growth of Verticillium spp. In vitro and in vivo, yet a high concentration is required (Borza et al, 2019). Resende et al (2002) studied the use of an S-methyl esther of the benzo-(1,2,3)-thiadiazole-7 carbotioic acid (acibenzolar-Smethyl, ASM), a compound in the benzothiadiazole group and an analog of salicylic acid, known to be involved in the acquisition of systemic resistance by plants (Görlach et al, 1996;Lawton et al, 1996), for the induction of resistance against V. dahliae and Moniliophthora perniciosa ((Stahel) Aime & Phillips-Mora) (previously Crinipellis perniciosa (Stahel) Singer), the causal agent of witches' broom disease in cacao.…”

The vascular disease Verticillium wilt of cacao (Theobroma cacao), caused by the soilborne fungus Verticillium dahliae, is often qualified as a “minor” disease. However, it can cause severe losses locally, for example, in western Uganda and northeast of the Democratic Republic of Congo. This disease is difficult to control, notably due to an extended host range and prolonged survival in the soil. Therefore, Verticillium wilt must be addressed through an integrated disease management strategy as employed for other tree crops such as olive. Few studies, nonetheless, have focused on how to confront this disease in cacao. This paper aims to provide an overview of our knowledge on Verticillium wilt on cacao and the integrated disease management strategies for preventing and controlling it. Promising avenues based on findings in other crops that could be adapted to cacao are also explored. Good agricultural practices, genetic resistance, biological control, induced resistance, and the use of organic amendments with or without biocontrol agents are discussed. Moreover, the potential benefits of some of these solutions toward the resistance to other cacao diseases, abiotic stress, and nutrition improvement are presented.
