This disease is associated with retards of the bud germination and shoot development, early shoot vigor, and seed piece decay (Raid & Rott, 2012;Chapola et al, 2014). In the state of São Paulo, Brazil, C. paradoxa is the diseasecausing agent most commonly associated with a poor germination of seed piece (Carvalho, 1963;Rossetto et al, 1986).…”

The objective of this work was to evaluate the commercial formulations of Bacillus subtilis QST-713 and Bacillus pumilus QST-2808 on mycelial growth inhibition of Thielaviopsis paradoxa, for the control of the pineapple disease and growth promotion in sugarcane. The inhibition of mycelial growth was evaluated in paired culture tests. Bacillus isolates were transferred to Petri dishes 48 hours before the pathogen, and the zone of inhibition was determined. The direct effect of the autoclaved commercial formulations at 0, 0.001, 0.01, 0.1, 1.0, and 10.0% on the inhibition of pathogen mycelial growth was evaluated. Bacillus spp. potential in controlling the disease and promoting plant growth was evaluated in assays on plant development and disease severity, both under controlled conditions and in the field. Bacillus isolates inhibited pathogen mycelial growth; however, the isolates did not control the disease effectively in the growth chamber and in the field. In the field assay without infestation by the pathogen, all treatments with biocontrol agents and fungicide increased the yield of cane stalks and sugar per hectare, compared with the control. In the assay with infestation by the pathogen, the B. pumilus-based product (2.0 L ha-1) and fungicide differed from the control only for the variable number of tillers.

“…Even if the seed pieces are affected to a lesser extent, without the need for replanting, losses will occur in all plot cuts. These problems are aggravated by the mechanized planting, in which smaller seed pieces are used, resulting in fewer buds and more injuries (Raid & Rott, 2012;Serafim et al, 2013;Chapola et al, 2014).…”

“…This pathogen contaminates sugarcane setts and seeds and leads to irregular germination and destruction of sugarcane stands. It can cause a 50% reduction in sprouting and reduce the yield by more than 42% ( Chapola et al., 2014 ). This pathogen thrives under conditions with long-term humidity and low temperatures.…”

Environmental stresses are the main constraints on agricultural productivity and food security worldwide. This issue is worsened by abrupt and severe changes in global climate. The formation of sugarcane yield and the accumulation of sucrose are significantly influenced by biotic and abiotic stresses. Understanding the biochemical, physiological, and environmental phenomena associated with these stresses is essential to increase crop production. This review explores the effect of environmental factors on sucrose content and sugarcane yield and highlights the negative effects of insufficient water supply, temperature fluctuations, insect pests, and diseases. This article also explains the mechanism of reactive oxygen species (ROS), the role of different metabolites under environmental stresses, and highlights the function of environmental stress-related resistance genes in sugarcane. This review further discusses sugarcane crop improvement approaches, with a focus on endophytic mechanism and consortium endophyte application in sugarcane plants. Endophytes are vital in plant defense; they produce bioactive molecules that act as biocontrol agents to enhance plant immune systems and modify environmental responses through interaction with plants. This review provides an overview of internal mechanisms to enhance sugarcane plant growth and environmental resistance and offers new ideas for improving sugarcane plant fitness and crop productivity.

“…T. ethacetica) [24][25][26][27][28]. Contrastingly, while pre-harvest burning resulted in a substantial decrease in the survival of soilborne insect pests populations and fungal plant pathogens' inocula, with no burning, mechanical harvesting maintains sugarcane straw as abundant crop residues in the areas, favoring the survival of both insect pests and plant pathogens [18,20,[29][30][31][32][33]. In fact, in areas where harvest was carried out without prior burning, there was a 1.5% decrease in sugar levels due to damage caused by Mahanarva fimbriolata on stalks [34].…”

“…This is because the pathogen rots and destroys the infected cuttings or setts (i.e., sugarcane segments that sprout to form new stalks) (Figure 1C), which are prevented from sprouting or undergoing further development, impacting the final plants' stand per area [27,32,37]. Controlling pineapple root rot has become a growing concern for local sugarcane growers and plantation extension personnel [20,23,25,30,37]. Similarly, since the prohibition of pre-harvest crop burning, the incidence of pineapple sett rot associated with T. paradoxa has also significantly increased in Brazilian sugarcane fields, which led to high yield losses [25,36,37].…”

Sugarcane dry rot emerged as an important stalk disorder in newly expanded plantations in northwestern São Paulo, Brazil, under the current no-burning fully mechanical harvest policy gradually implemented in the past 20 years. This emergence was probably due to a considerable increase in both pathogen inocula and insect pest populations in sugarcane crop residues kept in the field. In this study, we surveyed the incidence of three stalk-related disorders in commercial sugarcane fields in six municipalities in northwestern São Paulo and the corresponding yield losses. The three stalk-related disorders surveyed were as follows: the red rot disease caused by the fungal pathogen Colletotricum falcatum, the spittlebug-induced shoot stunting, and the stem dry rot, which is associated with the simultaneous infection of C. falcatum and Thielaviopsis paradoxa, the pineapple set rot pathogen. Red rot disease was detected in 88.2% of the fields surveyed, while the spittlebug-induced shoot stunting disorder and the internal stem dry rot were found in 97.1% of the fields. Stem dry rot had the highest incidence and resulted in the highest yield losses. Total sugarcane yield losses were estimated at 20.1%, with an average of 14.2 (±3.8) t·ha−1 per field. The multiple regression model constructed to determine which of the three stem-related disorders contributed the most to total yield losses was not significant. Subsequently, the performance analyses of single-variable polynomial regression models indicated that the simple linear model was the best fit in terms of independently predicting sugarcane yield losses based on each stem-related disorder. Positive and significant correlations were only detected between sugarcane yield losses in t·ha−1 and the incidence of red rot disease or leafhopper-induced shoot stunting. We concluded that the stalk’s internal dry rot, as a disease complex associated with both C. falcatum and T. paradoxa, was the most important disorder in sugarcane fields in the northwest region of São Paulo state. A sustainable pest management program is needed to reduce the impact of all three stalk-associated disorders on regional sugarcane production.
