英文摘要	Guayule (Parthenium argentatum Gray) is gaining a wide attention as natural rubber crop that is successfully grow in the arid and semi-arid regions. Genetically improving of guayule germplasm for higher rubber production and maximizing agronomic practices are the prioritized research areas. Among agronomic practices is weed control, where weeds compete with guayule plants and thus could reduce its productivity. To study the effect of herbicides on transplanted guayule seedlings and weeds survival rates, four post-emergence herbicides were tested. Three guayule genotypes were planted in a repeated split plot arrangement and sprayed with the post-emergence herbicides at different concentrations and time intervals. Results showed that after second spray, herbicide type and concentration had significant effect on guayule seedlings survival rate. Paraquat rates were effectively able to control weed growth and viability but affected survival of guayule seedlings. Paraquat at 840 g a.i. ha(-1) resulted in 96% of guayule seedlings survived, and 97.8% of weed populations were inhibited. More studies with different concentrations for other herbicides are required. The optimal concentration of paraquat herbicide has non-significant effect on guayule plant height compare with control treatment, suggests herbicide effects on guayule plant are most effective during seedling establishment stage. When use new herbicide application caution should be paid to control weed growth in the same time reduce the damage on guayule plants.
