Margoja (Orobanche) is a parasitic weed and is a Master Weed for many crops and it causes about 30 - 40% or sometimes even more damage in crops mainly mustard and some other crops. It becomes very difficult for the farmers to control it. It does not contain any chlorophyll so that it can make its own food through photosynthesis.

Each Orobanche plant can produce more than one million seeds in a short time period of eight weeks. These seeds can remain active in the soil for up to 10 years. And their germination is stimulated by the secretion of the root of the crop plant.There is no immediate solution to the outbreak problem of Orobanche except to adopt crop diversification and sustainable farming practices such as:

1, ) Adopt crop rotation. Don't take mustard crop in the field affected by Orobanche for the next two years.

2) Break the plant from the top before the seeds of Orobanche appear.

3) Soil Solarization with deep plowing of the field in summer.

4.) Right mulching practices.
