Abstract
In order to study of the efficacy of herbicides in weed control of new seeded alfalfa, an experiment was conducted in Hamedan and Yazd cities, Iran during 2009-2010. The treatments were Bentazone (Bazagran) (SL 48%) two, three and four L.ha-1, 2,4-DB (Butress) (EC 42.3%) 2.5, 2.8, 3.1 and 3.5 L.ha-1, ...

In order to study of the efficacy of herbicides in weed control of new seeded alfalfa, an experiment was conducted in Hamedan and Yazd cities, Iran during 2009-2010. The treatments were Bentazone (Bazagran) (SL 48%) two, three and four L.ha-1, 2,4-DB (Butress) (EC 42.3%) 2.5, 2.8, 3.1 and 3.5 L.ha-1, Imazethapyr (Pursuit) (SL 10%) 0.4, 0.7 and one L/ha and without herbicide control treatment. The herbicides effect on alfalfa biomass and the biomass and density of weeds was studied during three cuttings. In Yazd, 2,4-DB 3.5 L.ha-1 was the best treartment for controlling weeds and increasing alfalfa biomass. 2,4-DB 3.5 and 2.8 L.ha-1 controled the density and biomass of Malva and Lactuca to 100 and 88 percent, respectively. In Hamedan, herbicides treatments had no phytotoxocity on alfalfa. Only Bentazone caused chlorosis in alfalfa that recovered that after one to two weeks. 2,4-DB not only was suitable in control ling broad leaves weeds, but also was successful in field bindweed control. Overall. 2,4-DB seems to be an efficient herbicide

This research was undertaken to determine the comparative phenology of swallow wort (Cynanchum acutum) in pistachio orchards and investigate the possibilities of its integrated management as a randomized complete block design with 18 treatments and three replications during 2007. The treatments consisted using Paraquat, Glyphosate, Triclopyr and removine the weed. The results indicated that swallow wort growth started from emerging at zero GDD and ends at 2848 cumulative GDD. Formation of pistachio shell was almost at the same time with the beginning of flowering and pollination of swallow wort and pistachio harvesting were taken during the middle of swallow worth fruiting. The corresponding stages for pistachio had cumulative GDD 2365. Overall, two times weed removal + Triclopyr was the best treatment for reduction of swallow worth stem number. Three times Paraquat three l/ha was the best treatment for reducing in swallow wort stem biomass (97%).

The biology and phenology of broomrape (Orobanche nana) on Almond (Prunus dulcis cv. Mamaei) was studied during the growth season in Shahrekord city of Iran in 2004. Twenty trees which were infested by broomrape, were selected. Results indicated that almonds need 2120.5 growth degree days (GDD) to complete phenological stages from flowering to fruit ripening. Based on the cardinal temperature of broomrape (9.5°C), the parasite weed needs 209, 1125.5, 1414.5 and 961 GDD for completion of seed germination, stem emergence, flowering and seeding stages, respectively. Maximum seed germination occurred at the depth of 18 cm. Maximum root infection was observed at the depth of 9 to 12 cm. The highest infection to this parasite plant was recorded on roots with 9 to 11.9 mm diameter.
