ABSTRACT Citrus gummosis is an important disease because it causes the death of young plants, resulting in their replacement, a costly operation. Its causal agents are different species of Phytophthora. Dissemination of these microorganisms occurs mainly by contaminated nursery trees. Differences in aggressiveness, competitiveness and response to fungicides varied among species of this pathogen. Therefore, this study aimed to examine diversity among citrus isolates of Phytophthora from two different origins in São Paulo State. Thirty isolates from citrus nursery trees from 13 municipalities and 11 from seven commercial orchards were analyzed. Interspecific diversity was performed by species-specific primers and sequencing of the ITS region. Subsequently, intraspecific diversity was carried out with 16 RAPD primers and clustering analysis of UPGMA, using the Dice coefficient. Our data identified only P. nicotianae from either substrates or commercial fields. Isolates clustered into two genetically distinct populations. Genetically similar isolates were also found. The existence of these clonal lineages among isolates from geographically distinct nursery trees suggests an efficient dissemination mechanism. This was the first study to examine the diversity of Phytophthora in citrus from substrates of nursery trees in Brazil.

Forty-five genotypes (clones) of rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Müell. Arg.] of different origins were assessed for efficiency of early selection at the Votuporanga Experimental Station in northwestern São Paulo State, Brazil, using a randomized complete block design with three replications and six plants per plot. Girth at 120 cm above the highest point of the grafting union of each tree was taken at ages 12, 24, 36, 48, 60, 72, 84 and 96 months. Highly significant differences in girth were detected among the genotypes at all ages evaluated, except for 12 months. Estimates of genetic variance for two age sets showed a substantial increase with age, while the genotype variation decreased. Selection made at 24 months proved to be the most efficient, giving a superior gain per unit of time.

The urban population increase in the world, the economic expansion, and the rise in living standards associated with society’s habits and lifestyles accelerated the municipal solid waste (MSW) generation in undeveloped countries, such as in Brazil, in which the generation increased by 25% from 2012 to 2017. In the same period, the São Paulo state, the richest Brazilian state, increased its municipal solid waste generation by 51%. All this MSW needed to be collected and transported, and this process has a high economic and environmental cost. Therefore, this study aims to identify, using spatial analysis, the routes used by MSW trucks to estimate the distances traveled to dispose of the MSW on a regional scale considering all municipalities in the São Paulo state. The findings showed that the landfill numbers decrease, mainly individual ones, which receive MSW only from the city where it is located. Otherwise, the consortium landfills number is increasing, as well as the number of municipalities that share the same disposal site. Consequently, the distances to transport MSW from urban areas to final disposal sites increased by about 55% from 2012 to 2017, reaching 613 million kilometers during this period. This total distance is sufficient to make more than 12,806 laps on Earth and contribute to high fuel consumption and greenhouse gas emission.
