**Organophosphorus Degradation Technology Plan (Autumn Cabbage and Spinach)**
The test crops included autumn cabbage and spinach, with one group for each species and a total of two groups. Each group consisted of five experimental plots, with each plot measuring 33 m², resulting in a total area of 90 m². The base fertilizer used was farmyard manure.
Below is the experimental design:
| **Project** | **Drug** | **Organophosphorus Residue** | **Insect Survey** | **Yield** |
|--------------------|-----------------------------------|------------------------------|-------------------|-----------|
| Number 1 | Organic Phosphorus | | | |
| Number 2 | Seaweed Extract + Atropine | | | |
| Number 3 | Biopterin | | | |
| Number 4 | Seaweed Extract + Organic Phosphorus | | | |
| Number 5 | Seaweed Extract + Biapozyme + Atropine | | | |
| Number 6 | Fertilizers in Base Fertilizer | | | |
Each plot was covered with plastic sheeting to prevent cross-contamination between treatments. All drugs were applied strictly according to the manufacturer’s instructions.
Biapozyme was applied 2 hours after the application of organic phosphorus or 2 hours before harvesting. One tablet per 33 m² was used, combined with atropine 1 hour before harvest. The mixture should be fully dissolved and sprayed within 1 hour of application.
For organophosphorus residue testing, samples were collected and sent to a certified local inspection department for analysis. During the growing season, observations were recorded at each growth stage.
Seaweed extract was diluted 800–1000 times and sprayed every 7 days. This treatment enhances plant disease resistance and promotes healthy growth. The iodophors formed during spraying help degrade organophosphorus compounds by breaking down the "iodine-phosphorus" bond.
Organophosphate insecticides such as dichlorvos, 1605, 1259, etc., enter the plant and bind to the phosphoryl group in cholinesterase, causing its release. Acetylcholine then binds to organic phospholipids in plant fluids, making it non-toxic. This method shows good efficacy against 1605, 1059, Tepu, and ethionium, but less effective against dichlorvos, dimethoate, trichlorfon, malathion, diazinon, methamidophos, propylamine fluorophosphate, and octopamine.
Atropine is commonly available in pharmacies. It is used at a rate of 2 tablets per square meter (33 m²), crushed and dissolved in water, then mixed with seaweed extract for spraying.
Biapozyme is used by rotating the bottle in the direction indicated on the packaging until the enzyme powder falls into the diluent. Shake well until fully dissolved and apply at a ratio of 500 ml per bottle in 160 liters of water, covering 1 mu of land. It should be fully sprayed onto leaves and foliage. It directly targets organophosphorus residues, degrading the phosphoenzyme chain and breaking down toxic components into non-toxic, water-soluble molecules.
**Notes:**
1. Seaweed extract and atropine can be mixed.
2. Biapozyme must be used alone.
3. All anti-drug treatments should be applied 2 hours before sunrise or after sunset to ensure optimal effectiveness and safety.
