Performance of sweet potato genotypes in Brazilian regions
Mello,Alexandre Furtado Silveira; Silva,Giovani Olegário da; Nunes,Maria Urbana Correa; Celestino Filho,Pedro; Silva,Waltenis BragaABSTRACT: The average yield of sweet potato (Ipomoea batatas (L.) Lam.) in Brazil is below the crop potential, and appropriate cultural practices and more productive cultivars are needed to improve crop yield. The Beauregard sweet potato cultivar, originally from the United States, has shown high productive potential. This study evaluated the performance of features of agronomic importance of the Beauregard cul...
Alternative products in the "in vitro" inhibition of Sclerotinia sclerotiorum
Mello,Alexandre Furtado Silveira; Lourenço,Silvia de Afonseca; Amorim,LilianThe white mold, caused by Sclerotinia sclerotiorum, is a very important disease in tomato crops. The objective of this work was to study the effect of plant extracts, animal residues and industrial by-products extracts on the fungus in vitro growth. Treatments consisted of different concentrations of pyrolignous oil, neem oil, monosodium glutamate, sewage sludge and organic compost [coffee residue (50%) coal re...
Development of Colletotrichum gloeosporioides isolated from green pepper in dif...
Mello,Alexandre Furtado Silveira; Machado,Andressa Cristina Zamboni; Bedendo,Ivan PauloControl of anthracnose in green pepper involves the use of resistant varieties and/or fungicides. The selection of varieties and efficient products demands great amounts of conidia as inoculum. It is thus necessary to optimize the production of Colletotrichum gloeosporioides conidia in the laboratory, establishing the best conditions for fungus development. The present study aimed at determining the most favora...
