  • BUD ROT IN COCONUTCAUSED BY BACTERIA

  • SYMPTOMSGROWING TIP OR BUD DECAYS

  • PREVENTIONCUT AND BURN SEVERELY AFFECTED PLANTSREMOVE ALL AFFECTED TISSUE OF CROWN AND APPLY BORDEAUX MIXTURE

  • ROOT WILT IN COCONUTCAUSED BY BACTERIA

  • SYMPTOMSDECAYING ROOTSGENERAL YELLOWING AND MARGINAL NECROSIS IN LEAVESOVERALL PRODUCTION DECREASES

  • PREVENTION

    CUT AND REMOVE DISEASE ADVANCED PLANTSAPPLY BALANCED DOSE OF CHEMICAL FERTILISER

  • BLIGHT DISEASE IN PADDYCAUSED BY BACTERIA

  • SYMPTOMSLEAVES DRY FROM TIP TO BASESPOTS APPEAR ALONG EDGES OF LEAVES

  • PREVENTION

    SUPPLYING A BALANCED AMOUNT OF PLANT NUTRIENTS ESPECIALLY NITROGEN

  • DECAY DISEASE IN RUBBERCAUSED BY FUNGUS

  • SYMPTOMSSTEM SHRUNKS, SPLITS AND RED FLUID OOZES OUT FROM SPLIT REGION

  • PREVENTION

    PAINTING WITH FUNGICIDES

    SPRAYING BORDEAUX MIXTURE FOR TREES NOT IN TAPPING

  • QUICK WILT IN PEPPER CAUSED BY FUNGUS

  • SYMPTOMSLEAVES WITH WATER SOAKED LESIONS AND FIMBRICATE MARGIN

  • PREVENTION

    THROUGH PROPER WATER REGULATIONCROP ROTATIONUSE OF HIGH TEMPERATURE BY STEAM HEAT

  • BUNCHY TOP DISEASE IN PLANTAINCAUSED BY BANANA BUNCHY TOP VIRUSVECTOR APHIDS

  • SYMPTOMSNew leaves that are produced are narrower than normal, yellow, and flat Any fruit is produced, which is unusual, it will be deformed

  • PREVENTIONCHEMICAL CONTROL OF APHID VECTORSDESTRUCTION OF INFECTED PLANTS

  • CONCLUSION Since the beginning of agriculture, generations of farmers have been evolving practices for combating the various plagues suffered by our crops.

    Following discovery of the causes of plant diseases in the early 19th century, our growing understanding of the interactions of pathogen and host has enabled us to develop a wide array of measures for the control of specific plant diseases

    The goal of plant disease management is to reduce the economic and aesthetic damage caused by plant diseases
