Question: aphids on plums
natural method to protect plums from harmful insects
Answer: aphids on plums
more and more people who grow fruit plants in the garden love to grow them naturally, to have greater security on the garden products they bring to the table.
Surely the first mission of the organic farmer consists in the prevention and in the correct cultivation care: a healthy plant, correct fertilizations and waterings (not deficient, not excessive), the right insolation, the presence in the garden of grass, shrubs and other trees, which can host insects antagonists of harmful insects; these are all tricks that remove the probability that harmful insects settle on our plants.
Despite everything, it still happens that some insects settle on fruit and leaves.
In organic agriculture, in general, there is a tendency to carry out chemical treatments only when parasitic insects are already present on plants, avoiding preventive spraying.
Against aphids in organic agriculture, pyrethrum or rotenone based products are used; if the infestation is very heavy, the active ingredient is mixed with mineral oil, which allows a better adhesion to the plant.
Spraying is preferably done in the evening or in the early hours of the morning, avoiding the flowering periods, during which we would also disturb useful insects.
