Sugarcane orange rust was recently introduced into Brazil and its control is based on the use of resistant varieties. This study aimed to determine the reaction of Brazilian sugarcane varieties to the disease in the field and to compare artificial inoculation methods. Rust severity was assessed in 17 varieties at a 15-day interval. The maximum disease severity (MS%) and the area under the disease progress curve (AUDPC) were determined for each genotype. The artificial inoculation methods tested were: spraying of a spore suspension on 60-day-old plants in the greenhouse, or placing the spore suspension into the leaf whorl of 5-month-old fieldgrown plants. Nine out of the 17 varieties studied were resistant to the disease, including the most widely grown in new plantings, RB867515 and RB966928. Varieties RB72454, SP89-1115 and SP79-2233 were susceptible, while RB925211 and SP81-3250 were moderately susceptible. Varieties RB855156, RB92579 and SP83-2847 showed an intermediate reaction. Both inoculation methods correlated well with field results. Spray inoculation discriminates better the responses of the varieties and enables the evaluation of more disease variables. Leaf whorl inoculation allows the use of field-grown plants and generates results in a shorter time.

“…Among all major crop diseases, 70-80% are caused by pathogenic fungi, and viruses, bacteria and oomycetes account for the remainder ( Li et al, 2017 ; Peng et al, 2021 ). In sugarcane, more than 240 diseases have been described, among which red rot and Fusarium stem rot, leaf scald, ratoon stunting, mosaic, red streak, brown spot, brown rust and orange rust are the main concerns in Brazil ( Saumtally et al, 2000 ; Cheavegatti-Gianotto et al, 2011 ; Gonçalves et al, 2012 ; Srivastava and Rai, 2012 ; Chaves et al, 2013 ; Morais et al, 2015 ; Sharma et al, 2017 ; Urashima et al, 2017 ; Borella et al, 2021 ; Costa et al, 2021 ). Some diseases may also involve multiple organisms as part of a complex multitrophic system, which will be further investigated in this review.…”

Sugarcane multitrophic interactions: Integrating belowground and aboveground organisms

Sugarcane is a crop of major importance used mainly for sugar and biofuel production, and many additional applications of its byproducts are being developed. Sugarcane cultivation is plagued by many insect pests and pathogens that reduce sugarcane yields overall. Recently emerging studies have shown complex multitrophic interactions in cultivated areas, such as the induction of sugarcane defense-related proteins by insect herbivory that function against fungal pathogens that commonly appear after mechanical damage. Fungi and viruses infecting sugarcane also modulate insect behavior, for example, by causing changes in volatile compounds responsible for insect attraction or repelling natural vector enemies via a mechanism that increases pathogen dissemination from infected plants to healthy ones. Interestingly, the fungus Fusarium verticillioides is capable of being vertically transmitted to insect offspring, ensuring its persistence in the field. Understanding multitrophic complexes is important to develop better strategies for controlling pathosystems affecting sugarcane and other important crops and highlights the importance of not only studying binary interactions but also adding as many variables as possible to effectively translate laboratory research to real-life conditions.
