ADVANTAGES COMPARISON
We compared the advantages of Pyrifluquinazon with other insecticides from the following five dimensions:
1. Advantages of mechanism of action: selective nAChR agonist
| Comparison Items | Pyrifluquinazon | Traditional neonicotinoids (such as imidacloprid) | Pyrethroids (such as cypermethrin) |
| Target receptor | Selective activation of specific subtypes of insect nAChRs | Non-selective activation of insect nAChRs | Acts on sodium channels |
| Toxicity to bees | Low toxicity (contact LD50 >100 μg/bee) | Highly toxic (LD50 <0.01 μg/bee) | Moderate toxicity |
| Systemic | Bidirectional conduction (upward to new leaves, downward to roots) | Only conducts upward | No systemic |
| Fast-acting | Stop eating for 1-2 hours, peak mortality within 24 hours | Effective in 6-12 hours | Knocked out quickly (within 1 hour) but easily revived |
Advantages summary:
It is safer for pollinating insects and suitable for use during the flowering period.
Its bidirectional systemicity can protect new tissues and lasts for 14-21 days.
It has a balance between rapid effect and long-lasting effect, reducing the cost of repeated pesticide application for farmers.
2. Resistance management advantages
| Comparison Items | Pyrifluquinazon | Neonicotinoids | Organophosphorus (e.g. Chlorpyrifos) |
| Status of resistance | At present, there are few reports on global resistance | Aphids and planthoppers have been widely resistant | The resistance was severe and easy to cross resistance |
| Site of action | Different from the binding sites of neonicotinoids | Overlap with targets such as imidacloprid | Acetylcholinesterase inhibitors |
| Applicable scenarios | The preferred rotation agent for resistant pests | It should be used in combination with other agents | Be phased out |
Summary of advantages:
Highly effective against neonicotinoid resistant pests (e.g., Bemisia tabaculata, Planthopper brown).
It can be used as a key rotation agent in resistance management strategies.
3. Environment and ecological security
| Comparison Items | Pyrifluquinazon | Neonicotinoids | Organophosphorus (e.g. Chlorpyrifos) |
| Risk to bees | Low (EU rating: limited use) | High (EU banned clothianidin, etc.) | High |
| Aquatic toxicity | Low toxicity to fish (LC50 >100 mg/L) | Moderate toxicity (e.g. Imidacloprid LC50 10-50) | Highly toxic (chlorpyrifos LC50 <1 mg/L) |
| Residue of soil | Half-life 14-30 days (easily degradable) | The half-life can reach 100-300 days | Persistent residue |
Summary of advantages:
Meet the EU, North America and other strict ecological regulations.
It has little effect on natural enemy insects (such as ladybird and parasitoid wasp), which is conducive to integrated control (IPM).
4. Crop suitability and mixing flexibility
| Comparison Items | Pyrifluquinazon | Avermectin | Ethyl ester of snail |
| Suitable crops | Broad spectrum (fruit and vegetable, field, cash crops) | Mainly fruits and vegetables | Fruits and vegetables, cotton |
| Compatibility of mix and mix | Compatible with most agents (except strong alkaline) | Sensitive to PH | Avoid oxidizing agents |
| Collocation of resistance management | + Ethyl spirochete (enhanced oophorid control) | + Ethylspinosyn (retards resistance) | + Flupraziquantel (bidirectional internal inhalation) |
Summary of advantages:
Single or combined use can cover the whole life cycle of pests (adults and nymphs).
It is suitable for flying control, drip irrigation and other application methods.
5. Economic and social benefits
| Comparison Items | Pyrifluquinazon | Conventional agents |
| Frequency of medication use | 1-2 times/season (long duration) | 3-5 times/season (e.g. pyrethroids) |
| Cost of labor | Reduce (reduce application times) | Higher |
| Space for premium | High-end markets (e.g., organic orchards, export bases) | Regular price competition |
Summary of advantages:
Long-term use can reduce the cost of integrated control, especially for high-value cash crops.
