“…In the experiment 3, although the population of P. zeae decreased in the plots treated with carbosulfan at least until four months after planting, there were no differences between the treatments regarding yield. This occurred because RB867515, the variety planted in the experiment 3, is tolerant to P. zeae (Dinardo-Miranda et al 2019) were observed in plots treated with carbosulfan, the highest yields were also observed for this treatment, differing significantly from the control. In these two experiments, the yield in treatments with B. subtilis + B. licheniformis did not differ from the control or the treatment with carbosulfan.…”

“…The most used nematicides in sugarcane are the chemical ones, which rapidly reduce nematode populations and protect the growing plant from damage. Although these products maintain a low population of nematodes for only a few months after application, they contribute to significant increases in yield in infested areas, when compared to untreated areas (Dinardo-Miranda & Mengatti 2004, Dinardo-Miranda et al 2008, Dinardo-Miranda et al 2010, Silva et al 2006). However, since chemical nematicides in the soil are associated with environmental impacts, researches with biocontrol agents have acquired a greater importance.…”

The management of nematode infested areas includes several measures, among which chemical nematicides are the most used. However, since their use is associated with environmental impacts, researches with biocontrol agents have acquired a greater importance. This study aimed to evaluate the performance of Bacillus subtilis + B. licheniformis, when applied to the planting furrow, on nematode control and its effects on sugarcane yield. Five experiments were carried out in infested areas, with four treatments: control - no nematicide; carbosulfan 700EC 4 L ha-1 - standard treatment; B. subtilis + B. licheniformis at 0.16 kg ha-1 and 0.20 kg ha-1. Carbosulfan was more efficient in controlling the nematodes, reducing the populations at least four months after planting. The treatments with B. subtilis + B. licheniformis were more effective in the control of Meloidogyne javanica, when compared to Pratylenchus. The plots treated with carbosulfan produced 11 % more than the control. There was no difference between the B. subtilis + B. licheniformis doses, in relation to yield. The plots treated with the biological product produced 5 % more than the control.

“…Both compounds were previously tested in different varieties of sugarcane and an increment of 10% and 5% was also observed. The authors explained these differences by measuring levels of nematode infestation, which indicate the efficiency of pesticides applied in the studies [39,40]. Carbamates penetrate into the phytoparasite nematode and induce changes in metabolism leading them to death [41].…”

The use of agrochemicals has become a standard practice worldwide to ensure the productivity and quality of sugarcane crops. This study aimed to analyze the metabolic changes in sugarcane culms treated with five different nematicides. The experimental design was randomized in blocks, and agro-industrial and biometric variables were evaluated. The samples were extracted and then analyzed using LC–MS, LC–MS/MS, and LC–HRMS. The data obtained were submitted to statistical methods (PCA and PLS). Fragmentation patterns, retention time, and UV absorptions of the main features were analyzed. The plantations treated with carbosulfan (T4) obtained higher agricultural productivity and total recoverable sugar (TRS), while the use of benfuracarb (T3) was associated with lower growth and lower TRS. Statistical analysis revealed the contribution of the features at m/z 353 and m/z 515, assigned as chlorogenic acids, which discriminated the groups. The MS profile also supported the occurrence of flavonoids (C-glycosides and O-glycosides) in the samples.

“…In sugarcane fields, rhizosphere conditions define root development, which is affected by plant-microbial interactions, nutrient and water availabilities (Darrah 1993), soil characteristics, root exudates and root decomposition (Singh et al 2013), andsoil pests (Dinardo-Miranda andFracasso 2010;Dinardo-Miranda et al 2019). Although all factors above may affect sugarcane regrowth, here the role of root system size as a source of reserves was addressed and there is no reason for assuming that this dependency is not present in field-grown plants.…”

The root system is essential for sugarcane regrowth and the vigor of ratoon cycles as it represents the unique source of carbon skeletons and energy for the initial plant development. However, root system dynamics after shoot harvesting and its role in sugarcane regrowth remains poorly known. Here, it was hypothesized that sugarcane plants with small volume of root system will accumulate less biomass after shoot harvesting than plants with larger volume and that such regrowth is dependent on root reserves. In sugarcane plants grown in nutrient solution, shoots were cut, and two root treatments were established: reference plants with the entire root system (100%); and plants with half of the root system (50%), randomly removing half of root system. After 37 days of shoot harvesting, plants with the entire root system showed higher shoot, root and total dry mass, root length, root diameter, root area and root volume, when compared with those with 50% of the root system. Sugarcane plants with the entire root system had higher root content of starch, soluble sugar and nonstructural carbohydrates as compared to plants with 50% of the root system. A significant positive correlation was found between the variation of shoot dry mass and the variation of root nonstructural carbohydrates. Interestingly, this data revealed a disproportionate effect of root system size on sugarcane regrowth, with plants with the entire root system accumulating almost three times more biomass than plants with half of the root system during regrowth.
