Sugarcane is one of the main Brazilian crops, present in small and large agricultural properties, with low and high technology. However, phytosanitary problems are a major concern to any degree, as in most of these problems, there is loss of product quality and / or reduced production. Thus, the objective of the work was to evaluate a population fluctuation of Saccharicoccus sacchari (Hemiptera: Pseudococcidae) and Mahanarva posticata (Hemiptera: Cercopidae), an infestation of complex the Diatraea saccharalis (Lepidoptera: Crambidaeaceae) and Colletotrichum falcatum (Glomerellales: Glomerellaceae) and record the occurrence of natural enemies, in two varieties of sugar cane, called regional “Palito” and commercial RB-867515, submitted to the presence and absence of chemical fertilization, during the caneplant cycle and first cane-soca. In addition, the objective was to develop and validate a standard area diagram with color photographs (SADcp) for brown rust, caused by the fungus Puccinia melanocephala (Uredinales: Puccinaceae) and a temporal dynamics of the disease. It was found that the variety RB-867515 had a higher incidence of S. sacchari, which was influenced by the average temperature and a greater number recorded in the months of May and April with a temperature of 23ºC. The cut of M. posticata occurred from April to August with an average of less than 7% and the infestation of the D. saccharalis/C. falcatum complex was 1% for both sugarcane cycles. The presence of the natural enemies Doru luteipes (Dermaptera: forficulidae), the mass of pupae of Cotesia flavipes (Hymenoptera: Braconidae), coccinellids (Coleoptera: Coccinellidae), chrysopids (Neuroptera: Chrysopidae) and entomopathogenic Aspergillus fungus were recorded. The diagram proposed in this study serves to assist in the visual estimate of the severity of brown rust on sugarcane leaves. As for the temporal dynamics, a brown rust occurred in the months taken, with greater severity in the colder seasons between May and August (20 to 22ºC). Brown rust was identified in the two varieties of sugarcane, but one RB867515 variety was less intense and chemical fertilization increased the disease severity in the Palito variety.

Phytonematoids are among the main pathogens in the Arabica coffee culture, in which the species Meloidogyne exigua gains prominence. Due to the complexity of handling in the field and the high toxicity of chemicals that target its management, alternative techniques have been investigated to reduce the population of this pathogen in the field. Among the alternatives, the use of low toxicity nematicides and the application of biological products as biofertilizers have recently gained prominence in the management of gall nematodes. However, due to the great diversity of microorganisms present in these formulations of biofertilizers, it is necessary to carry out the morphological and genetic characterization in order to understand the genetic diversity. The aim of this study was to access the genetic diversity of microorganisms present in biofertilizers used for the management of M. exigua; and to evaluate the isolated and combined effect of different chemical nematicides and biofertilizers in the management of M. exigua in commercial Arabica coffee plantations in the region of Iúna, southern Espírito Santo. The isolates were obtained from serial dilutions of biofertilizers in different culture media for further visual analysis of morphological characteristics. For the genetic characterization, Rep-PCR was performed using REP, ERIC and BOX primers. The agarose gels were photographed and later analyzed in the GelJ program, in which the similarities between the digitized profiles were calculated using the Jaccard Similarity Coefficient (CSJ), and based on the estimates of dissimilarities of the isolates were grouped by the UPGMA hierarchical method. In the field, chemical nematicides and biofertilizers were applied alone and combined and population measurements of M. exigua were carried out before application and 45 days after application of the products. From Vitaflex and Maxfert, 218 bacteria were isolated and included in 53 groups. Of this total, 40 groups were found in both biofertilizers and 13 groups present only in Vitaflex. In the field, the isolated application of Nimitz, Vitaflex and Maxfert resulted in a greater population reduction of M. exigua. The combination of biofertilizers with Nimitz also showed satisfactory results, making it possible to combine these products for the management of M. exigua in the field
