適於旱地生長之雜草多可在草坪及栽培之植生覆蓋上發生，直接或間接的影響景觀、衛生、安全及栽培植生之品質。一般而言，株型高大生長快速，可藉種子及營養繁殖器官繁殖之多年生草危害最嚴重；在精緻之草坪上，耐刈割或匍伏性之雜草最難防除。在本省刈割經常使用於上述場合之雜草防除。殺草劑主要用於果園而少用於草坪及路邊，以防治觀點言可改進之空間相當大。顧及防治效果、雜草演替及對栽培植生及環境衝擊之雜草管理體系亦需逐步建立。本文簡介草坪、果園及路邊植生覆蓋之重要雜草、雜草生態、可資利用之防除技術及特殊雜草之防除方法。

Many upland weeds are capable to infesting turf and the purposeIymaintained groundcover vegetations, causing problems relating toscenery, sanitation, traffic safety, and deteriorating the groundcovervegetations. 1n general, tall and fast growing perennial weeds whichpropagate both by seeds and vegetative organs are most troublesome.For fine turf, mowing-tolerant or prostrate weeds are most difficult tocontrol. Cutting, mowing, and herbicides are commonly used in Taiwanfor weed control in these above-mentioned situations. Herbicidesare primarily used in orchard, but not often used for turf and roadside conditions. Considerabie improvement could be made in termsof control efficacy. 1n the long run, weed management systems thatconsidering control efficacy, weed succession, impact on cultivatedvegetation as well as on enviroment need to be estab!ished. 1n thispaper, important weeds, weed ecology, available control techniques,and control of some special weeds are introduced.
