Eradication of Congress Grass using Mexican Black Bee:

Any one in little touch with the plant world is well aware of menace by the parthenium weed (known as Congress Grass), which wildly grows in the agricultural lands, severely affecting the crop production.  It can not be controlled easily.  All the research work and use of pesticides proved futile in prevention the weed.

        To address this severe issue, the KVK Sagroli, used the Mexican black bee as weed controller which feed only on the parthenium weed.  The black bees usually remain hibernated in the soil before June and rise along with the sprouting of the weed plants in monsoon.  Since the black bees feed on the weed and keep on multiplying in numbers and the weed gets completely eradicated.  The scientists suggested, around 200 bees need to be introduced per acre land to control the weed.
