With the right research and careful planning any fruits can be grown without pesticides. It is true that customers usually demand unblemished fruit and for this type of fruit to be produced one has to be very careful to protect the fruit from insects that are going to be harmful to the fruit. However, natural protection can be achieved.
For example it is quite possible to produce apples without pesticides. It’s important to try to do a few things to ensure their success such as choosing strains that are especially resistant to disease, choose proper sight conditions, and try to mimic the natural ecosystem around the sight in which you are growing the apple trees.
