کنترل علف هرز وایه‭(Ammi majus) ‬توسط علف کش کلوپیرالید(لونترال ‮‭300‬) و امکان اختلاط این علفکش با علفکشهای رایج در مزارع گندم استان خوزستان

Field trials were conducted to control (Ammi majus) by Clopyralid (Lonterl 300) and mix ability this herbicide to other herbicides to control extra range weed in 1383-84 and 84-85 in Agricultural Center in Shushtar of Mianab. Experiment with randomized complete block design was used with 14 treatments and 4 replications. Experiment treatments evolved: Clopyralid (500 cc/ha), Clopyralid (500 cc/ha) + 2, 4 - D MCPA (1.5 lit/ha), Clopyralid (500 cc/ha) + Bromoxynil (2.5 lit/ha), Clopyralid (500 cc/ha) + Bromoxynil + MCPA (1.5 lit/ha), Clopyralid (500 cc/ha) + Tribenuron - methyl (20 gr/ha), Clopyralid (500 cc/ha) + Phenoxaprop - P- ethyl (1 lit/ha), Clopyralid (500 cc/ha) + Diclofop - methyl (2.5 lit/ha), Clopyralid (500 cc/ha) with Sitogate oil ( 2*1000) + Clodinafop - propargyl (1 lit/ha), Tribenuron (20 gr/ha), Clopyralid + 2, 4 - D (2.5 lit/ha), Bromoxynil + MCPA (1.5 lit/ha), Bromoxynil (2 lit/ha), 2, 4 - D + MCPA (1.5 lit/ha), weedy control and weed free control. In all treatments, Clopyralid used with sitogate oil (2*1000). Results showed in two year experiments (Ammi majus ) controlled by Clopyralid well. Clopyralid, could be control weed such as (Scorpiurus muricatus) and (Sylibum marianum) too. Weed such as (Beta maritima) and (Malva sylvestris) were eradicated by this herbicides (30-60%). Cloprralid mixture with other experiment herbicides were controlled especially 30 days after spraying, weed suth as (Brassica arvensis), (Malva sylvestris), (Beta maritima), (Scorpiurus muricatus), (Phalaris minor), (Lolium perenne) and (Avena ludoviciana) well. The result of experience showed that significant difference among 15 and 30 days after spraying in controlling (Ammi majus) by conventional broadleaf herbicides. 15 days after spraying live weed in square meter were controlled well. However 30 days after spraying because of reemerged this weed, excluded from control range of this herbicides. (Gullium) and (Anagalis) didn , t control by non of existence herbicides. Result showed that herbicides such as Tribenuron - methyl and Fenoxaprop - P - ethyl didn , t recommended because of disability to herbicide control. However Clopyralid herbicide didn, t apply in wheat field in khuzestan now. Therefore, because of (Ammi majus) were dominanced in many Khuzestan fields and to notice to result of this experiment recommended that this herbicide were used to many broadleaf and grass, until (Ammi majus) and other broadleaf and grass were controlled together
