Fruit tree transplantation

The parasites which cause plant diseases may be spread by wind, rain, insects, birds, snails, slugs, and earthworms, transplant soil, nursery grafts, vegetative propagation (especially in strawberries, potatoes, and many flowers and ornamentals), contaminated equipment and tools, infected seed stock, pollen, dust storms, irrigation water, and people. Figure 3.8 illustrates the effects of microbial infection of various fruit trees. 

Alar promotes fruit setting of grapes and accelerates by several days the maturing of cherries. It also is used on apples, prunes, tomatoes, peanuts, and various ornamental crops. On apple trees, Alar increases the firmness of the fruit and prevents it from dropping permaturely. On tomato transplants, the compound retards stem elongation.
