Certainly, here is an article on control of flower dropping in oranges:
Oranges are a popular citrus fruit and are grown worldwide. However, it is common for orange trees to experience flower drop, which can affect fruit production. Flower drop is caused by various factors, such as environmental conditions and diseases. Fortunately, there are several ways to control flower dropping in oranges.
Firstly, it’s essential to understand the different types of flower drop. Abscission, the first type, occurs when there are fewer resources available to the tree than needed to support the developing fruit. This can happen due to various reasons like drought, frost, nutrient deficiency, or over-cropping. The second type is physiological, where the plant naturally discards some flowers, and the cause is unknown.
To prevent abscission, the most critical step is to provide adequate irrigation to the trees. Too little or too much water can both cause flower drop. Excessive irrigation results in a lack of oxygen to the roots of the plant, leading to waterlogging and root death. Conversely, a lack of water results in dehydration of the plant leading to water stress, which can cause the tree to abort flowers. Proper nutriment management is also essential for ensuring optimal plant growth and reducing flower dropping.
Another way to control flower drop is to maintain optimal soil pH and nutrient balance. Soil testing is crucial for maintaining the proper pH and nutrient levels, as different plants have different preferences.
Pesticides and fungicides can also be used to control flower drop by preventing damage to the tree. Spraying the plants with these can help prevent pests, like mites and aphids, from harming the tree and protect them from diseases like citrus canker.
In conclusion, controlling flower drop in orange trees is critical to ensuring a healthy crop yield. By ensuring adequate irrigation, proper nutrient management, and using pesticides or fungicides when necessary, it is possible to minimize the effect of environmental factors on the trees and maximize fruit production. Don’t forget to consult with a local agronomist to understand the specific soil and climatic requirements of your region.
