    Most fungicides are preventative, meaning they have to be applied before the disorder occurs. Try better air circulation, not to compact ground, to givevthe plant the conditions it desires. Cultural conditions basically. Thanks

    There would be little or nothing there avalable to the home gardener. There is less and less chemicals available year on year. Its moving towards biological and cultural control for plants. Whats affecting your plant and what is the plant.

    are you talking about the likes of mildews? i wouldn't accuse myself of being an expert by any means, but i suspect the colder temperatures mean that the time to treat them is past, and they won't be much of an issue over the winter.

    Most plants have a relationship with mycorhizal fungi around their roots that increase absorption of water and nutrients and benefit the plant. There are also fungi on your plants that do not cause any damage to them and so called commensalistic microbes can help prevent infection with more damaging fungi. Some gardeners advocate using compost tea to boost the population of non pathogenic microbes on plants and so benefiting their plants. Many fungi also produce spores that can travel through the air particularly when humidity and moisture levels are high so killing all fungi is not likely to provide a long term solution. Removing and burning badly effected parts of the plant and allowing good air circulation should help. Most plants have some natural tolerance to fungi and good cultural conditions should help prevent problems developing. There are varieties of many plants that have better resistance to particular fungal infections but you will need to identify what fungi is atttacking your plants and you may need to completely remove plants that are badly infected.
