A surface sampling method for analysis of pesticide residues in pome fruit was studied by layer-by-layer scan from pericarp to kernel. Phoxim residues of apples, pears and papayas was determined by GC-MS, respectively, in core, different layers of pulp, peel ,as well as the whole fruit. Phoxim residue content was decreased when depth of the layer increased. It was inferred from experimental dat...

Apple stem grooving virus (ASGV) is one of the most important viral pathogens infecting pome and stone fruit trees worldwide. In this study, with the complete nucleotide sequence of isolate ASGV-T47, which we generated, molecular variation and recombination in ASGV full genomic sequences worldwide were analyzed. ASGV-T47 shared 79.7-97.6% nucleotide identity with the other isolates worldwide an...

The effective management of Fusarium wilt bananas (FWB) depends on the knowledge disease dynamics in time and space. objectives this work were: to estimate intensity impact, investigate spatial temporal FWB. Fields planted with Silk (n = 10), Pome 17), or Cavendish 3) banana subgroups were surveyed Brazil, totaling 95 ha. In each field, all plants visually assessed, diseased georeferenced. inci...

Oil Palm Empty Fruit Bunches (OPEFB) have only been used as organic fertilizer by placing it between plants without prior treatment, a result, the decomposition process of OPEFB takes long time and produces toxic ammonia. The composting with variations in decomposer is solution utilizing compost best quality. purpose this study was to analyze effect Trichoderma sp, Azotobacter, Mill Effluent (P...

This presentation focuses primarily on recent developments in new technologies that have impacts on decay control. These technologies include 1-methylcyclopropene (1-MCP) and new preand postharvest fungicides. With the increasing use of 1-MCP in the apple industry, depending on varieties, many apples do not have to be drenched with diphenylamine (DPA) prior to storage. Because use of 1-MCP has ...
