Embodiment 1

[0008] The tool used is the Nonggong-15 sprayer. Before the rapeseed bolts, mix 60 grams of 50% isocuron wettable powder with 30-50 kg of water, stir evenly, and then control rapeseed weeds. After spraying the stems and leaves, chlorotic plaques appeared on the leaves of the buttercup 10 days later, and then gradually died. The above treatments are safe for rapeseed plants.

Embodiment 2

[0010] The tool used is the Nonggong-15 sprayer. Before the rapeseed bolting, mix 90 grams of 50% isocuron wettable powder with 30-50 kilograms of water, stir evenly, and control rapeseed weeds. After spraying the stems and leaves, chlorotic plaques appeared on the leaves of the buttercup 10 days later, and then gradually died. The above treatments are safe for rapeseed plants.

[0011] The actual herbicidal effect data of the method of the present invention are given below.
