    Study Notes

    Integrated Pest Management (IPM) in Rice

    • IPM combines multiple strategies to manage pests effectively while minimizing health and environmental risks.
    • Crucial principles include monitoring pest populations, identifying pests and beneficial organisms, and using a variety of control methods.

    Vertebrate Pest Control

    • Attractants can help in hand-picking pests by using specific plant leaves that snails find appealing.
    • Effective water management reduces snail activity; land leveling and drainage are critical.
    • Toxic plants like Monochoria vaginalis and tobacco leaves can strategically lower snail populations.
    • Preventing field entry involves using barriers, although snails can hibernate in soil during dryness.
    • Transplant healthy seedlings; timing and plant density may influence pest resistance.

    Weed Control Objectives

    • Aim to manage weed populations to minimize their impact on crop yield; not all weed presence leads to significant yield loss.

    Methods of Weed Control

    • Cultural: Utilizing disease-free planting materials, controlling weeds before seed production, and employing crop rotation strategies.
    • Mechanical: Includes handweeding, hoe weeding, mulching, and interrow cultivation to disrupt weed growth physically.
    • Biological: Introduces natural predators or pathogens to control weed populations effectively.
    • Chemical: Involves using herbicides, categorized by application timing (preplant, pre-emergence, post-emergence), movement in plants (contact vs. translocated), and selectivity (non-selective vs. selective).

    Weed Management Techniques

    • Mulching: Protects soil moisture, improves fertility, and obstructs weed emergence.
    • Water Management: Flooding fields can suppress weeds in crops like lowland rice.
    • Burning: Clears vacant areas to minimize weed growth effectively.

    Herbicides for Rice

    • Anilides:
      • Butachlor and Pretilachlor are selective, pre-emergence herbicides targeting mainly grass.
    • Propanil:
      • Selective, post-emergence herbicide applicable at the 1-4 leaf stage for grass control.

    Types of Biological Control

    • Classical: Involves introducing natural enemies to control weeds where they are not naturally occurring.
    • Inundative: Utilizes mass-reared natural enemies released periodically in the fields.

    Notable Weed Pathogens

    • Aquatic weeds can be targeted by fungi and viruses, offering alternatives to chemical treatments for weed management.
