Fungicides applications for commercial producers can be found at.
For commercial fruit plantings, fungicides may be applied after the flood water has receded and it is determined and that fruit crops are still alive. Do not fertilize fruit crops after July 1 as fertilization after this date often promotes late season growth that results in winter injury. When the soil is still moist, stake any trees that have fallen over. Do not use sand, mulch, or other soil types that will alter the internal drainage properties or texture of the existing soil when adding soil around plant roots. If the soil has eroded, fill in these spots with the same soil type that is in the orchard. If a new layer of silt or other debris has been deposited over the original soil surface, remove it and restore the soil surface to its original level. To reduce damage to flooded fruit plantings, drain the field as quickly as possible by pumping or digging new drainage channels. Flooded peach trees can wilt within six, ten, and sixteen days when the temperature is 80, 71, and 63☏., respectively. Also, the higher the soil temperature, the greater the plant injury. Summer floods cause greater root damage than those in the spring. Hypertrophied lenticels (white, spongy tissue) may also be present on the underground rootstock shanks of fruit trees.
Reduced foliar and fruit growth may also occur and roots may fail to regenerate. Other plant symptoms of waterlogging include leaf epinasty (downward bending and twisting), chlorosis, or abscission. The first plant symptoms usually observed after a short period of flooding are wilted leaves and an unpleasant odor that often emanates from the injured or dead roots, which appear brown. Leaching and denitrification may also occur. In waterlogged soils, reduced ions (NO 2 -, Mn 2+, Fe 2+, S -) and phytotoxic byproducts of microbes can accumulate and restrict root metabolism. After this, root permeability and mineral uptake is reduced. Plants respond by reducing water absorption and closing their stomata, resulting in a lower rate of photosynthesis. The lack of soil oxygen induces several changes in plants and soils that adversely affect vegetative and fruit growth. Microorganisms consume much of the oxygen in water and soil. Shortly after flooding, gas exchange between the soil and air is greatly reduced. Although fruit trees may produce a crop in the year of the flood, they may still die the following growing season when subjected to stress. However, after the flood water recedes, Phytophthora root rot may occur on some crops. For small fruit crops, the most sensitive to flooding are strawberry (can tolerate submersion in water for up to seven days), blackberry, raspberry and currants, while blueberry, grape, and gooseberry are relatively more tolerant of waterlogged soils. Roots of peach and apricot trees are highly sensitive to waterlogged soils, roots of cherry and plum trees are intermediate, and those of apple and pear are the least sensitive.
