Wheat crop is highly infested by the sucking insects such as aphids due to the lush green color of foliage. Chemical control of the insects induces a negative effect on crop growth and yield. Farmers must cultivate the canola crop on borders around the wheat crop to trap the insects. The greenish color of the foliage and the bright yellow color of the flowers of canola attract the insects. This is how the farmers protect their crops from insects without chemical use.
