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.
