Frequently Asked Questions (FAQs) and Answers:
Q1: What is the importance of pesticide rotation?
• A1: Pesticide rotation helps prevent pests from developing resistance to specific chemicals, ensuring long-term effectiveness.Q2: How do different insecticide modes of action work?
• A2: Insecticides can target the nervous system, growth regulation, respiration, or other critical functions in pests, leading to their death.Q3: Can combining insecticides speed up resistance development?
• A3: The impact of combining insecticides on resistance development is still debated, but it’s generally recommended to rotate different modes of action rather than combining them.Q4: Are there any organic insecticides that are effective?
• A4: Yes, spinosad is an example of an organic insecticide that is effective against certain pests, particularly caterpillars.Q5: What products are recommended for armyworm control?
• A5: Products like Acelepryn and Ference are recommended for effective and long-lasting control of armyworms.
