CONCEPT OF BIOLOGCAL CONTROL AND INTEGRATED DISEASE MANAGENENT

CONCETHE USE

 OF NATURAL PROCESSES TO COMBAT pathogens is very helpful it involves introduction of pathogens natural enemies into environment in casa of malaria for example introduction of small fish in ponds and ditches has been an effective method to minimize the growth of larvae and pupae of mosquito vector biological past control involves exposing them to predators and parasites

GROWING plants in climates that are unsuitable for the pathogen can control plant diseases Interplanting as it stimulates conditions in natural ecosystems by limiting the spread of infectious diseases can also control it Another effective method is eradication of disease which is achieved by crop rotation

IT IS the practice of growing different crops on the same ground in successive years rather then repeatedly growing it year after year through crop rotation the chances of establishing a particular weed parasites affecting that crop is reduced Moreover soil fertility can be increased by introducing a crop of leguminous family which have nitrogen fixing bacteria in their root nodules
