The National Center for Plant Pest and Animal Disease Prevention and Control (Wiqa’) issued an important warning to farmers across the Kingdom, urging them to strictly adhere to integrated pest management programs. This warning comes as part of ongoing efforts to mitigate the significant economic damage caused by whiteflies to agricultural crops and to ensure the sustainability and quality of plant production.
The center explained that the whitefly, despite its small size, is one of the most dangerous agricultural pests globally. Its danger lies in its feeding method; it directly sucks plant sap, leading to significant weakening, yellowing of leaves, and a decline in growth and productivity. Its damage is not limited to this, however, as it also acts as a primary vector for many serious plant diseases, especially viruses, which can wipe out the entire crop, exacerbating the losses suffered by farmers.
General context and severity of the problem
The whitefly (Bemisia tabaci) is a globally widespread pest, finding an ideal environment for rapid reproduction in warm climates, such as those prevalent in the Kingdom. Historically, this insect has caused significant losses to agricultural sectors in many countries worldwide. One of the most prominent indirect damages it causes is the secretion of a sticky, sugary substance known as honeydew, on which sooty mold fungus grows. This mold coats the leaf surface, reduces the efficiency of photosynthesis, and negatively impacts fruit quality and market value.
The importance and impact of integrated pest management
The “Wiqa’a” Center emphasized that the optimal solution to combat this pest does not lie solely in relying on chemical pesticides, but rather in adopting an Integrated Pest Management (IPM) strategy. This sustainable approach combines several preventative and curative methods to keep pest populations below the level that causes economic damage, while reducing reliance on chemicals and maintaining ecological balance. This strategy includes sound agricultural practices such as weed and infested plant removal, using resistant varieties, ensuring good ventilation in greenhouses, and adhering to appropriate planting distances.
The center also urged farmers to regularly monitor their crops for early detection of any infestations and to utilize biological control methods by releasing the whitefly's natural enemies. It emphasized that the judicious use of pesticides should be a last resort, selecting specialized types that do not harm beneficial insects. The success of these efforts will not only protect local farmers' crops but also contribute to enhancing the Kingdom's food security, a key pillar of Vision 2030, and maintain the reputation of Saudi agricultural products in regional and international markets.
