The Effect Of Adjuvants On Apple Disease Management, Chelsi Patricia Abbott Jan 2016

The Effect Of Adjuvants On Apple Disease Management, Chelsi Patricia Abbott

Open Access Theses

The management of common apple diseases such as apple scab ( Venturia inaequalis) and bitter rot (Colletotrichum spp.) relies heavily on effective fungicide applications. However, the development of fungicide resistance to newer fungicides has resulted in management failures and significant economic losses. This has led to a greater reliance on captan, an older fungicide, because there is a low risk of pathogens developing resistance. Label restrictions limit growers to 18 kg of captan per season, which may not provide sufficient control of both apple scab and bitter rot in wet years. Consequently, apple growers are faced with two …


Impact Of Microwave Processing On Quality Of High Value Shelf Stable Fruit Products, Milena Maria Leon Garcia Jan 2013

Impact Of Microwave Processing On Quality Of High Value Shelf Stable Fruit Products, Milena Maria Leon Garcia

Open Access Theses

Fruits and vegetables are a rich source of health promoting micronutrients and phytochemicals, and their consumption has been associated with reduction of many chronic and degenerative disease. Thermal processing techniques are used to preserve quality and extent of the shelf life of foods, although these traditional processes are associated with specific quality changes in fruits and vegetables. Compared to traditional thermal processing methods, microwave heating provides the potential to improve product quality by virtue of its energy transfer mechanism that provides rapid volumetric heating of food and can potentially enhance overall quality of processed fruit and vegetable products. Though direct …
