Potential of simple salts to partially substitute for conventional foliar fungicides - PS2117

Description
In 2004, 6,000 tonnes of complex chemicals were sprayed on crops in the UK to prevent damage and yield loss from diseases caused by fungi. In a few crops in some countries it has been discovered that very simple salts which are used as food ingredients, such as potassium bicarbonate, can control some diseases and replace conventional complex chemical fungicides. The aim of this research is to examine the scientific and technical literature for evidence that such salts may be able to partially replace some of the fungicide used on crops in the UK. The most likely salts and target diseases in major UK crops will be identified for future research. Further work will be needed to find out how best to use the salts in practical farming to reduce the use of conventional fungicides.
Objective
1. To review the scientific literature on fungal disease control with simple salts for both protected and field crops on a global basis.

2. To review the current commercial use of salts for fungal disease control for both protected and field crops on a global basis.

3. To assess the scope for potential use of simple salts on fungal pathogens of major conventional and organic crops in the UK, alone or in combination with conventional fungicides, leading to a recommendation of crops, target pathogens, salts and conventional fungicides (where appropriate) warranting further research and development in collaboration with industry through LINK.
