Abstract: 

IN ORDER TO REACH A PROPER CONTROL OF WEEDS IN COTTON FIELDS, A NEW CULTIVATOR IS INVENTED WHICH IS CAPABLE OF BOTH "INROW" AND "OVER THE TOP OF ROW" WEED CONTROL. THIS CULTIVATOR IS COMPARED WITH COMMON CULTIVATORS AND CONVENTIONAL METHOD OF WEED CONTROL IN COTTON FIELDS. THE EXPERIMENTAL HAS PERFORMED IN RANDOMIZED COMPLETE BLOCK DESIGN WITH 8 TREATMENTS AND 3 REPLICATIONS. TREATMENTS WERE: 1-FULL-SEASON WEED CONTROL (HOEING).2- COMPOUND CULTIVATOR 3- ENVOKE (TRIFLOXYSULFURON-SODIUM 75 WG) HERBICIDE 15 GHA-1 4- NO WEED CONTROL 5- CONVENTIONAL CULTIVATOR+PRE-EMERGENCE TREFLAN (TRIFLURALIN 48% EC) HERBICIDE 2.5 LHA-1 6-COMPOUND CULTIVATOR+PRE-PLANT SOIL INCORPORATED TREFLAN HERBICIDE 2.5 LHA-1 7- CONVENTIONAL CULTIVATOR+PRE-PLANT TREFLAN HERBICIDE 2.5 LHA-1 8- COMPOUND CULTIVATOR+PRE-EMERGENCE TREFLAN HERBICIDE 2.5 LHA-1. WEED CONTROL PERCENT AND SEED COTTON YIELD IS MEASURED. THE RESULTS INDICATED THAT THE MAXIMUM WEED CONTROL OBTAINED FROM HOEING. THIS TREATMENT DID NOT SHOW SIGNIFICANT DIFFERENCES WITH ENVOKE, COMPOUND CULTIVATOR+PRE-EMERGENCE AND PRE-PLANT TREFLAN AND COMPOUND CULTIVATOR ALONE. THE MAXIMUM SEED COTTON YIELD OBTAINED FOR HOEING WITH 2822.2 KGHA-1. THE YIELD OF THE COMPOUND CULTIVATOR AND ENVOKE TREATMENTS WITH 2533.3 AND 2600 KGHA-1 RESPECTIVELY, HAD NO SIGNIFICANT DIFFERENCES WITH HOEING.
