The apple tree (Malus domestica) is a Rosaceae species widely grown in temperate regions due to its adaptability and the high value of its fruits. It prefers cool climates and medium-textured, well-drained soils with a pH of 6.0–7.0. Balanced nutrition is required, particularly nitrogen, to avoid excessive vegetative growth. Proper canopy, irrigation, and fertility management ensures stable yields and high-quality fruit.

Bud break for apples

In apple orchards, uniform bud break is essential to achieve a balanced canopy and consistent production. When sap flow is unevenly distributed—due to stress, temperature fluctuations, or physiological imbalances—apical dominance increases. This results in irregular vegetative regrowth and, consequently, irregular flowering and fruit set.

FOLICIST® supports proper hormonal balance and helps the plant overcome abiotic stress during bud break. Its application improves sap flow distribution and harmonizes vegetative reawakening, reducing apical dominance. The result is more uniform bud break, more consistent flowering, and higher productive potential throughout the crop cycle.

Flowering and fruit set for apples

In apple, flowering and fruit set are crucial stages that determine fruit number and quality. Environmental stresses such as low temperatures, water shortages, or nutritional imbalances can reduce pollen fertility, interfere with fertilization, and limit fruitlet formation, causing uneven fruit set.

FOLICIST®, applied at the green cluster/white balloon stage, regulates hormonal and osmotic balance, improving flower vitality and fruit set efficiency. The product reduces the impact of abiotic stress and promotes more uniform flowering, better fruit distribution, and overall higher productivity.

Fruit Sizing for apples

In apple trees, fruit sizing is a crucial stage that determines final yield and commercial fruit size. To support effective cell division and expansion, it is essential to ensure a targeted supply of nutrients and active substances that sustain the plant’s natural physiological processes.

KRISS® or KRISS® BIOLOGICO (approved for organic farming), specific growth-promoting formulations, support uniform fruit development. Their application stimulates metabolic activity and improves assimilating transport toward the fruits, contributing to uniform size without compromising firmness or organoleptic quality.

Calcium deficiency (bitter pit) for apples

In apple, adequate calcium intake is essential for cell wall strength and stability, directly influencing fruit quality and storability. The low mobility of calcium can limit its availability in developing tissues, favoring physiological disorders such as bitter pit.

GLIBOR Ca™, based on calcium and boron, promotes rapid absorption and better nutrient translocation to fruits, improving firmness, texture, and resistance to physiological disorders. This helps enhance organoleptic quality and postharvest shelf life.

Fruit Coloring for apples

In apple, fruit coloration is a key quality parameter strongly influenced by variety, environmental conditions, and agronomic management. Intense and uniform coloration not only improves visual appeal but also increases commercial value.

SUNRED® stimulates the mechanisms responsible for pigment synthesis and maturation. Its application helps standardize coloration, improve fruit appearance and overall organoleptic quality.
