Pruning is the removal of a portion of a tree to correct or
maintain tree structure. Training is a relatively new practice in which tree
growth is directed into a desired shape and form. Training young fruit trees is
essential for proper tree development. It is better to direct tree growth with
training than to correct it with pruning.
As a principle of pruning, use sharp tools to make sharp
cuts to avoid extended pieces of branch (nubs). It is not recommended to cut
close to trunk instead make collar cut to avoid cracking the branch of the tree
and there is no need to paint cuts.
Pruning is most often done during the winter, commonly
referred to as dormant pruning. Training includes summer training and summer
pruning as well as dormant pruning. The goal of tree training is to direct tree
growth and minimize cutting.
BENEFITS OF PRUNING:
Balance cropload and vegetative growth.
Improve light penetration.
Improve insecticide/fungicide efficacy.
Increase air movement.
Decrease disease.
Increase fruit size (Thin fruit buds, reduce yield)
Facilitate mechanical harvesting.
Rejuvenation.
Fumigation
Fumigation is use to eliminate nematodes, replant disease
and eliminate or reduce weed populations, which are all serious factors that inhibit
the proper development of fruits crops.
Acute fumigant poisoning causes eye irritation, sore throat,
headaches, nausea, vomiting, breathing difficulties and aggravated asthma, and
neurological effects such as convulsions, dizziness, or tremors. Fumigant
exposure also has long-lasting effects that include cancer, respiratory damage:
Exposure to fumigants can cause permanent respiratory damage, neurological
effects, reproductive & developmental effects, immune system effects, and
endocrine disruption.
