Decay Control with New Tools
نویسندگان
چکیده
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 been changing the traditional way the industry used to handle apples, non-drench-based measures for decay control are needed for the MCP-based fruit handling system. In 2004, two new postharvest fungicides, Penbotec (pyrimethanil) and Scholar (fludioxonil), were registered for use on pome fruits. Some preharvest fungicides that have the potential to control postharvest diseases are becoming available. This presentation is organized as three parts: first, the major postharvest diseases we are dealing with; second, strategies for decay control; and third, updates on the use of preand postharvest fungicides for decay control.

Strongly stable multi-time stepping method with the option of controlling amplitude decay in responses
Recently, multi-time stepping methods have become very popular among scientist due to their high stability in problems with critical conditions. One important shortcoming of these methods backs to their high amount of uncontrolled amplitude decay. This study proposes a new multi-time stepping method in which the time step is split into two sub-steps. The first sub-step is solved using the well-...

متن کاملRelationship between Dead Trees with Soil Physico-chemical Properties and Earthworm in Mixed Broad-leaved Forest Stand (Case study: Sarcheshmeh Forest, Chaloos)
Dead trees protection, has a key role in structural and biogeochemical processes in forest ecosystems. Some aspects of dead tree dynamics have been carefully studied, but the kind and decay degree of dead trees and forest soil properties have not received enough attention. The aim of this research was to study the effect of a kind and decay degree of dead trees on soil mineral properties in the...
