Farmers in Kolathur were trained to weed out purple nut (Khoorai Kizhangu) in maize fields here recently.
At a training programme organised by the Salem branch of Dhanuka Agritech, farmers were explained the importance of maize crop that was called the Queen of Cereals. Due to purple nut (Cyperus Rotundus), also called as world’s worst weed, the crop is completely damaged resulting in heavy yield loss. The training programme was organised in the farm belonging to R. Sundaresan and S. Munusamy at Periyathanda village in Kolathur. In the fields, farmers were shown the complete drying and death of the weed in 20 to 25 days after spraying Sempra Herbicide at 36 g per acre. Also, the participants were explained the mode of action, stages of application, other crops recommended, rain fastness and effect on succeeding crops, said S. Ganesan, senior development manager.
