One of the serious problems in Pistachio gardens is Weed that compete to production and some of which are hosts of some Pistachio pests such as Pistachio Bugs . Determining vegetation of garden floor is very important to weed management of pistacio gardens . In this study Flora of weeds in Pistacio gardens were determined and dominant species were introduced . Identification of species were determined using key and sampling were carried out in 3 gardens at least at 5 points randomizely using 1m2 Quadrate . In each quadrate number of species was counted and dominant species was determined for each region . The results showed that 64 species belonging to 18 families were identified of which 37 % were Perennial and the rests were Annual . The most species collected from Pistacio gardens of Yazd province belonged to Gramineae with 14 species . Phalaris minor , Cressa cretica , Cynodon dactylon , Alhagi camelorum , Acroptilon repens and Convolvulus arvensis were dominant species .
