Control of narrow-leaved weeds in direct rice cultivation fields in dry bed with combined use of herbicides

To compare the efficiency of different herbicides in controlling narrow-leaved weeds of rice drying fields of Gilaneh cultivar with the focus on the use of pre-growth and post- growth herbicides, this study was conducted as a block design with 4 replications in Research field of Rasteh, Hashem Abad station was conducted in 2021 crop year. Experimental treatments was Stomp herbicide application (3 liters per hectare), Puma super (1 liters), Puma super (2 liters), nabu-s (2 liters), Propanile (10 liters), Sunrice (100 ml) Penoxsulam (250 ml), Thiobencarb (6 liters), Ronstar (3 liters), Clomazone (1000 ml), Titanium (2 liters). Effect of herbicide application on number of grain clusters, number of clusters square meter, thousand grain weight, fresh and dry weight of rice plant, fresh and dry weight of straw, fresh weight, fresh and dry weight of paddy, number weeds and dry weeds of Sesame, number weeds and dry weeds of wheat, number and dry and fresh weights of weeds of Echinochloa crus-galli, Cyperus rotundus, purslane, Cucumis melo var. agrestis, Convolvulus arvensis, Fallopia convolvulus, Cleome viscose, Cynodon dactylon and Prosopis farcta were significant. To obtain the highest number of grain clusters, number of clusters square meter, thousand grain rice, yield of rice, fresh and dry weight of paddy, the yield of straw and stubble, the herbicide Pumasuper 2 liters and also to obtain the highest plant weight rice and fresh and dry weight of straw, Ronstar herbicide are recommended.
