The Prevention Center warns: Causes and methods of combating dust mites in palm trees

Introduction: Palm trees are a national treasure and face ongoing environmental challenges

The date palm is a cornerstone of agriculture and the economy in Saudi Arabia, deeply intertwined with its cultural heritage and food security. The Kingdom is a major global producer and exporter of dates. However, this agricultural expansion has brought with it new environmental and climatic challenges for farmers, most notably agricultural pests that thrive in arid environments, particularly the dust mite, which poses a direct threat to crop quality.

Warnings from the "Wiqa" Center about the dust mite infestation

In this context, the National Center for Plant Pest and Animal Disease Prevention and Control (Wiqa’) emphasized the critical importance of early detection of the date palm fruit mite, known locally as the “dust mite” or “ghubeir.” The center classified this pest as a top priority due to the significant threat it poses to the productivity and quality of date palms across the Kingdom. The center stressed the need for close monitoring of date palms that were infested in previous seasons, along with the importance of observing the new leaves of neighboring palms within the farm. This effectively contributes to limiting the spread of infestations and enhancing the efficiency of control measures.

Environmental and agricultural factors contributing to the worsening of the pest

The Weqaa Center explained that the dust mite infestation is widespread throughout the Kingdom, and environmental factors play a crucial role in its proliferation. Among the most prominent of these factors are severe drought, low rainfall, and dust-laden winds characteristic of the desert climate. In addition, improper agricultural practices contribute to the increased spread of the infestation, such as the accumulation of infested agricultural waste and the growth of weeds around palm trees. Furthermore, the use of unsterilized agricultural equipment and the reliance on untrained labor that lacks adherence to hygiene and prevention measures are major factors in the transmission of the infestation.

Symptoms of the infection and its economic impact

Regarding how to identify the infection, the center explained that symptoms begin with the appearance of scratches and noticeable discoloration on the fruit, which tends to be light red or brown. As the infection progresses, the fruit's skin thickens and becomes ulcerated, eventually leading to the fruit drying out and hardening. This hardening prevents the fruit from growing normally and hinders its full ripening, which negatively and directly impacts the quality and economic value of the crop, reducing export opportunities for dates to global markets and affecting farmers' income.

Transmission methods and control strategies

The center indicated that the sources of the pest's spread are numerous, including transmission via agricultural equipment and workers, contact with infected trees or fruit bunches, and crop residues left in the field. Wind plays a significant role in dispersing the dust mite over long distances, especially during periods of drought. To combat this, the center urged farmers to implement integrated pest management programs, starting with regular inspections, safe disposal of weeds and debris, and the use of clean equipment. Preventive spraying with micronized sulfur, along with the addition of appropriate sticking agents, is also recommended to ensure effective treatment.

Food security and agricultural sustainability

If an infestation is confirmed, experts recommend using specialized acaricides under expert engineering supervision. Preventative spraying of infected trees is also essential during the following season, specifically in winter after the harvest. In conclusion, the center emphasized that raising farmers' awareness and implementing sound agricultural practices are the first line of defense for protecting the date palm sector. Preserving this national plant resource not only protects farmers' income but also aligns perfectly with the goals of the Kingdom's Vision 2030 in achieving food security, enhancing agricultural sustainability, and increasing non-oil exports.
