Germanium (Ge) is a chemical element used in several industrial processes. According to the Survey of Rocks and Soils of the Geological Service of Brazil (SGB-CPRM) this element is found in a wide territorial range in the country. Thus, The objective of this study was to evaluate the primary metabolism of Raphanus sativus when grown with different doses of germanium, in relation to photosynthetic performance and growth for three crop cycles. The experiment consisted of growing radish in 7 treatments containing germanium in the soil at concentrations of 0; 0.5; 1; 1.5; 2; 2.5; 3 mg kg-1. Analyses were performed over three complete cycles of the crop, from seedling production, transplanting and harvesting. The parameters analyzed in each cycle were: growth, chlorophyll concentration, chlorophyll a fluorescence, and stomatal conductance. The treatments with concentrations up to 1.5 mg kg-1, in all cycles, presented a better performance. Indicating a possible toxicity for levels above this. |

A 6-year field monitoring study was designed to compare the presence of fall armyworm Spodoptera frugiperda (J. E. Smith), leaf injury, its parasitoids, 100 seed weight, and seed yield of Bt maize hybrids approved for commercialization in the Brazilian market. Field trials were planted in two municipalities, divided into two periods, from 2011 to 2014 (period I), and due to the approval of different Bt hybrids, from 2015 to 2016 (period II). Treatments were Bt, non-Bt maize and all non-Bt maize sprayed with insecticide methomyl. Six Bt-maize hybrids were planted, expressing the following proteins: Cry1Ab, Cry1F, Cry1A.105 (Cry1Ab +Cry1Ac +Cry1F), Cry2Ab2a and Vip3. In 2015 and 2016 Bt Powercore was planted due to its commercial approval. The number of S. frugiperda larvae for most Bt hybrids was lower than on non-Bt hybrids, except for Fórmula TL and Herculex in period II, in both municipalities. In period I, Bt hybrids VT, VT 2 and Viptera showed almost no injury on their leaves, despite the high number of fall armyworm larvae found in plants. Different parasitoids emerged from larvae from Bt and non Bt hybrids: Archytas sp., Campoletis sp., Chelonus sp., Eiphosoma sp. and Ophion luteus. The average 100 seed weight was higher in municipality from Sete Lagoas for all Bt hybrids, non-Bt hybrids and non-Bt hybrids sprayed with methomyl, when compared to Nova Porteirinha during period I. Fórmula TL, non-Bt Fórmula TL sprayed with methomyl, and non-Bt Fórmula TL showed the lowest seed yield in both municipalities and periods.
