The objective of this work was to evaluate the vegetative development and determine the concentration of sodium, potassium, and calcium in watermelon (Citrullus lanatus) grown on two organic substrates and under increasing saline concentrations. The substrates were soil + earthworm humus (S1) and soil + bovine manure (S2), and the saline treatments consisted of irrigation water with different electrical conductivities: 1.36 (control), 3.56, 5.76, and 7.96 dS m-1. The experimental design used was a randomized complete block in a 2×4 (substrate × conductivity) factorial arrangement with five replicates. Main branch length, root length, stem diameter, leaf number, leaf area, and fresh matter mass of shoots and roots, as well as the sodium, potassium, and calcium contents in the plants, were determined. All phenological parameters interacted with the substrates, and S1 improved plant performance. Substrates interacted significantly with: leaf area; leaf number; stem diameter; main branch length; root length; fresh matter mass of shoots and roots; and the contents of sodium, potassium, and calcium, in both shoots and roots of watermelon irrigated with saline water for up to 27 days after emergence. There are also interactions between substrates and salinity for stem diameter, main branch length, fresh matter mass of roots, and calcium contents in both shoots and roots, and potassium and sodium contents in the roots. |

The citrus Huanglongbing (HLB), recognized as the most devastating citrus disease worldwide, was detected in Sao Paulo state, Brazil in 2004. The HLB management strategy employed in São Paulo is based on preventing new infections by reducing the inoculum (certified planting seedlings, psyllid control and removal of symptomatic plants). However, HLB continues to disseminate, reaching two neighbor states. In Brazil, citrus is cultivated country-wide (88% of the microregions produce citrus, responding for more than 30% of the planted area). If this dissemination pattern persists, there is a risk of emergence of HLB in areas not yet affected. To face this problem, exclusion strategies and early detection/eradication are crucial, specifically, tools, information and support for the action of phytosanitary defense agencies. The objectives of this Network are generate information that allows to defense phytosanitary agencies prioritize, anticipate or reassess actions relating to the exclusion or eradication of HLB, focusing on preventive actions to areas still unaffected. Since 2010, dataset (presence/absence of vector and bacteria, vector population measurements, etc.) are being obtained from different eco-regions of Brazil: south (cold), northeast (including semi-arid region) and north (amanzon). The analysis of the data until now shows that in the south and north regions the presence of the vector is uncommon or even rare. In contrast, in the northeast the presence is very common, and in the semi-arid region, the vector occurs, but in less abundant and sporadic fashion. Symptomatic plants and insect collected in all regions were tested and did not show the presence of the bacteria.
