Until recently on many farms it was routine practice to treat apples prior to storage with specific fungicides in order to control infections of fruit by fungi such as Gloeosporium, Botrytis, Monilinia and Phytophthora (see ' Disorders of the Flesh ' …
Clearly there will be continued pressure from consumers to reduce or eliminate the use of post-harvest chemical treatments for apples and other fresh produce. The number of products with label recommendations for use as post-harvest treatments has …
Information on the disposal of fungicidal drench solutions is no longer applicable as no products are approved for this use in the UK. In addition to fungicide dips and drenches, this section of the guide previously provided guidance on the post-harvest …
There are important advantages in being able to make a prediction of storage quality early in fruit development as opposed to harvest time. Early prediction allows growers more time to plan and organise their storage and marketing schedule and, where …
Where apples are produced in warmer climates than in the UK, there is much concern about the overuse of nitrogen fertiliser. In North America, at harvest, high nitrogen fruit tend to be larger, greener, softer, more subject to pre-harvest drop, and more …
Achieving adequate levels of phosphorus in Cox and Bramley apples at harvest reduces their susceptibility to low temperature breakdown (LTB) during storage. This is particularly important where climatic conditions during development increase …
Adequate potassium supply to apple trees is essential in order to achieve regular yields of high quality fruit. Potassium is particularly important in ensuring sufficient acidity in apples and for providing the characteristic taste to more acidic …
The most well known role of magnesium in plants is its occurrence at the centre of the chlorophyll molecule. In addition to this function inadequate levels of magnesium can inhibit CO 2 assimilation during photosynthesis. Consequently most of the concerns …
Boron is important in ensuring normal tissue development in plants. It is important in the development of the fine structure of cell walls, in facilitating sugar translocation and in the synthesis of nucleic acids. Adequate boron concentrations in fruit …
Effects of hard pruning on apple quality and storage potential are similar to those induced by light crops, either naturally or by thinning. Vigorous extension growth competes with the developing fruit for available water and mineral nutrients although …
