How to treat apple trees after flowering against pests: 20 remedies for all occasions

The apple tree is an easy-to-grow fruit crop, fairly resilient to adverse environmental factors. However, diseases and pests can destroy not only the harvest but also the tree itself. To prevent this, it's important to spray the trees with specialized pesticides in a timely manner. Treating apple trees is especially important after flowering, when pest and pathogen activity increases.

What pests can be dangerous for apple trees after flowering?

In addition to the pests listed above, the apple orchard is attacked after flowering by the following: goose beetle, spittlebug, small longhorn beetle, and apple sawfly.

What diseases should apple trees be treated for after flowering?

To maintain your orchard in good condition and preserve developing fruit, it's important to understand potential apple tree diseases after flowering and how to combat them. Typically, all diseases are fungal, viral, and bacterial in nature. They can be identified by external signs:

1. Powdery mildew – presence of dirty material on the leaf bladeswhite plaque, which turns brown over time. This results in leaf curling and drying, stunted growth of young shoots, and a significant deterioration in fruit quality. The disease progresses rapidly in high humidity and dense canopies. In advanced stages, the tree loses its vitality and ceases to bear fruit.
2. Scab Leaves, ovaries, and fruit stalks become covered with brown spots. The affected green matter dries up and falls off, and the fruit develops cracks in the skin and stops ripening.
3. Cytosporosis Gray ulcers that form on the tree bark gradually acquire a reddish-brown hue and become like a sponge. After the lesion spreads to the forks of the skeletal branches, the fruit tree dies.
4. Black crayfish The tree's bark becomes cracked and covered in black spots, the leaves develop brown spots, and rot develops on the fruit. Ignoring this problem leads not only to the death of one tree but also of the entire orchard, as the disease spreads rapidly.
5. Rust Brown spots appearing on the leaf blades rapidly spread across their entire surface and spread to the tree bark and branches. Pathogenic microorganisms drain the plant of all moisture and significantly reduce the quality of the fruit.
6. Milky shine The disease first attacks the foliage and then spreads to the bark. In a short time, the tree becomes very weak, its leaves and branches fall off, and the crop is completely lost.
7. Fruit rot Brown spots form on ripening apples, rapidly increasing in size. Within a few days, the disease affects all the fruits, which rot and fall to the ground. The flesh of these apples becomes completely inedible.
8. Bacterial burn – a disease brought into the garden by newly purchased cuttings and seedlings, usually appearing in mid-summer. The disease is accompanied by disfigurement and drying of leaf blades, as well as blackening and rot of the fruit.

2. Aktara quickly kills scale insects and leaf rollers. Dilute with water according to the instructions.
3. Benzophosphate – works great against a wide variety of pests.
