In this issue, we highlight the common causes of flower drop and deformed fruit in cucumber cultivation, especially under unstable weather conditions that affect flowering, pollination, and fruit development.

Weather Stress Affects Flowering and Pollination

With changing climate conditions, cucumber plants are becoming more vulnerable to stress. High temperatures, continuous rainfall, and high humidity can affect flower development, reduce pollen activity, and lower the ratio of female flowers. As a result, growers may face poor pollination, flower drop, and unstable fruit setting.

Rainy and Humid Conditions Increase Crop Risk

Long periods of rain and moisture can also interrupt pollen transfer and increase the risk of fungal diseases. When fruit development is affected, cucumbers may become curved, swollen, uneven in size, or form deformed “B-shaped” fruits. These problems can reduce product quality, market value, and overall farm income.

Strengthening Crop Nutrition for Better Fruit Setting

Under unstable weather conditions, relying only on soil fertilisation may not be enough. Foliar nutrition can help support flowering, improve plant strength, and encourage better fruit development. A balanced calcium and boron programme is especially important for improving flower retention and reducing fruit cracking or deformity.

MULTISUC & A-PlusCal for Healthier Crop Development

In the featured case, the grower used A-PlusCal together with MULTISUC as a foliar spray during the flowering stage. With continuous management, flower drop was reduced, the percentage of deformed fruit decreased, and the fruits became more uniform and stable.

For cucumber growers, managing flower drop and deformed fruit requires early attention to weather stress, nutrition balance, and disease pressure. With the right foliar nutrition programme, growers can support healthier flowering, improve fruit quality, and achieve more consistent yield.

At Advansia, we continue to focus on practical, field-tested solutions that match the real conditions faced by Malaysian growers. Whether the need is better flower retention, stronger fruit development, or more reliable disease control, timely action and suitable crop strategies remain key to achieving more stable results in the field.
