The two-spotted spider mite (Tetranychus urticae) (Acari: Tetranychidae) is a significant pest affecting numerous economically important legumes, field, ornamental crops, and fruit trees. Recognized by two distinct lateral spots on its adult body, this microscopic mite feeds on plant cells using a stylet, resulting in white or pale spots on foliage. Native to temperate zones, it has adapted to diverse environmental conditions. Under favorable conditions, its life cycle completes in 10–15 days, producing multiple generations per season. Damage severity varies with host susceptibility, environmental conditions, plant type and density, and crop rotation practices. Effective management is essential for quality crop production. Although numerous chemical controls exist, many pose environmental risks. The most sustainable approach is the development and application of an Integrated Mite Management (IMM) program. Key biological agents in IMM include fungal and bacterial species, predatory mites from the Phytoseiidae family, and botanical acaricides.

Agricultural extension plays a vital role in improving the lives of farmers and rural communities, disseminating information and skills, and ensuring sustainable agricultural development in rural areas. The planning of extension programs involves organizing extension activities, required budget, various projects, technical personnel, relevant skills, and others within a specific timeframe, usually conducted annually by the district-level extension unit. In many districts of Afghanistan, extension units have been established to provide extension services to farmers. The purpose of this study is to examine the mechanisms, challenges, and solutions of planning extension programs at the district level. The agricultural extension unit of Surobi district in Kabul province is considered as a case study. Data was collected through focused group discussions and interviews with local extension workers, lead farmers, and village elders. Additionally, library methods were also used. A main reason for farmers' limited access to extension services in the country is the poor planning of extension programs at the district level.
