Abstract
Field trials were conducted at Cereals Research Institute Badeggi, Nigeria to compare the effectiveness of CGA 362+Ametryn at 3.0kg/ha pre-emergence on weed control in sugarcane with the conventional recommended pre-emergence herbicides: Diuron at 4.0kga.i./ha, atrazine 3.0kga.i./ha, including the hoeweeding at 3,6 and 9 WAP and weedy check all laid out in a randomised complete block design. From the results in both years, the application of weed control treatments did not have any significant effect on the % germination count at 21 days after planting (DAP) and crop vigour score but was significant on weed parameters (weed cover score at 3,6 and 9 WAP and weed dry matter production at 8 WAP and sugarcane growth parameters (Stalk length and number of millable stalks/plot) and yield (ton/ha). Among the treatments, weedy check gave the poorest weed control, sugarcane growth parameters and yield. However, the best weed control was recorded in the plots treated with CGA362+Ametryn at 3.0kg a i/ha, and also its effectiveness on weed control resulted in higher sugarcane growth and yield above the recommended conventional pre-emergence herbicides treatment.
