• Carrot grass is a weed whose scientific name is Parthenium hysterophorus. This weed looks exactly like carrot plants, it is also known by the names Congress grass and in regional language safed topi, tej chandani etc.

• By mechanical means, in moist soil, this weed can be controlled to a great extent by uprooting it by hand or with a scabbard, collecting and burning it before flowering.

• Good quality manure can be prepared by burying the uprooted plants in pits of 3 to 6 feet by mixing it with cow dung.

• For chemical control of this grass, use 2,4 D @ 40 ml/pump, when carrot grass plants are at the 3-4 leaf stage, spraying can be done.

• In the non cropped area, Spray Glyphosate 41% SL @ 225 ml per pump mixed with clean water. For better results add in 250 gm ammonium sulphate and spray it. 

• For biological control beetle pests are capable of destroying carrot grass well, and do not have any adverse effect on other useful crops. In the first fortnight of June to October, the beetle insect is more active and about 3 to 4 lakh beetle insects are sufficient for 1acre.

• Sowing of some plants like cassia tora, marigold, wild amaranthus in April-May before monsoon reduces the transmission of carrot grass to the affected area.
