摘要

Glyphosate applied at 0.6 kg/ha at active vegetative stage caused yellowing and drying up of Mimosa invisa. 2, 4-D at very high dose (5 kg/ha) even though caused epinasty was ineffective. Paraquat applied at 1 to 1.2 kg/ha at active vegetative stage was effective, but the labour and time requirement for efficient spraying of the contact herbicide was very high. All the herbicides applied at seedling stage were ineffective because of fresh germination from seed bank. The best chemical for controllingM. invisa was glyphosate @ 0.6 kg/haand best time of application was active vegetative stage (100 days after germination).
