Hoeing and weeding
The crop should be kept clean of weeds. First hoeing may be done three weeks
after sowing and the second a month thereafter. The crop may be lightly earthed to save it
from lodging. Use of Basalin at the rate of 1 kg a.i. per hectare in 800-1000 L water as preplanting
spray has been found effective in controlling weeds in sunflower crop.
