Insecticide Pymetrozine 50% WDG

Pymetrozine 50% WDG (CAS 123312-89-0) – High Quality Insecticide for Control of Rice Planthoppers & Aphids | Professional Grade Water-Dispersible Granule Formulation

Product Name: Pymetrozine 50% WDG (CAS 123312-89-0)

Tagline: Advanced Insecticide for Targeted Piercing-Sucking Pest Control
Key Advantages:
1. Specialized control of piercing-sucking pests like aphids, whiteflies, and planthoppers
2. Ideal for pest management in high-value crops throughout growth stages
3. Low-residue, degrading into environmentally friendly by-products for sustainable farming

Pymetrozine 50% WDG is a water-dispersible granule insecticide engineered to combat piercing-sucking pests. Once applied, it quickly acts on pests, disrupting their feeding behavior. The WDG formulation ensures easy mixing with water and uniform distribution on crops. Designed for modern agricultural practices, it helps maintain pest-free crops, contributing to stable and high-quality crop production.

Precision Pest Interruption：Targets piercing-sucking pests like aphids and planthoppers specifically, blocking their feeding behavior rapidly.

Ideal for High-Value Crops：Suitable for pre-bloom, fruiting and other critical growth stages of high-value crops (e.g., fruits, vegetables), ensuring pest control without compromising crop quality.

Eco-Friendly Degradation：Breaks down into benign compounds over time, minimizing soil and water residue risks.

Long-Lasting Protection：Forms a durable protective layer on crops, providing extended pest control that reduces the need for frequent re-applications.

Target Crops:
Field crops (rice, wheat, corn)
Vegetables (tomatoes, cucumbers, eggplants)
Fruits (apples, grapes, oranges)
Nurseries and greenhouse-grown plants
Ornamental plants
Target Pests/Diseases
Piercing-sucking pests: Aphids (such as green peach aphids, cotton aphids), planthoppers (like rice planthoppers), whiteflies.
Principle of action: Disrupt the feeding behavior of piercing-sucking pests, causing them to stop feeding and eventually die, thus reducing damage to crops.
Application Methods
Foliar spray: Use standard agricultural sprayers. Dilute the product with water and spray evenly on the foliage of crops, ensuring complete coverage of leaves.
Drip irrigation: Compatible with drip irrigation systems for greenhouse and large-scale field use. The diluted solution is delivered to the root zone of crops through the drip system.
Sprayer application: Apply 300-600 L of the diluted solution per hectare.

Active Ingredien: Pymetrozine
Concentration: 50% WDG (Water-Dispersible Granule)
CAS Number: 123312 - 89 - 0
Physical Properties:

Appearance: Free-flowing off-white to light yellow granules
Solubility: Quickly disperses in water to form a uniform suspension without agglomeration
pH: 6.0 - 8.0

1. Prepare the spray solution: Calculate the required amount of Pymetrozine 50% WDG and water according to the application rate. Add the granules to water gradually and stir well to ensure complete dispersion.
2. Choose the right time: Apply during calm weather, preferably in the morning or evening when the temperature is relatively low and the wind is weak, to avoid rapid evaporation of the pesticide and ensure uniform coverage.
3. Even application: When spraying, keep the sprayer at a proper distance from the crop (usually 30-50 cm) and move at a uniform pace to ensure that the pesticide is evenly distributed on the crop surface.
4. Re-application: If it rains heavily within 2-4 hours after application, re-apply the pesticide after the weather clears to ensure the control effect.
5. Interval between applications: Maintain a 7-10-day interval between applications to achieve continuous pest control and avoid pest resistance.

Critical Precautions:
1. Personal protective equipment: Wear chemical-resistant gloves, goggles, and protective clothing during handling and application to prevent the 2. pesticide from contacting the skin and eyes.
2. Avoid inhalation: When mixing and spraying, stand in an upwind position and avoid inhaling the pesticide mist. Use in well-ventilated areas.
3. Storage: Store in a cool, dry place, away from direct sunlight, food, and feed, and out of the reach of children and pets.
4. Disposal of containers: Thoroughly rinse empty containers three times and puncture them before proper disposal in accordance with local environmental regulations. Do not reuse the containers for other purposes.
5. Pre-harvest interval: Ensure that the pesticide residue in the crop meets safety standards before harvest(e.g., 7-14 days depending on the crop).

Field Trials:
In rice field trials, Pymetrozine 50% WDG achieved an 80-90% reduction in rice planthopper populations, effectively protecting rice from pest damage and ensuring stable rice yields.
In vegetable (such as cucumber) field trials, it reduced aphid infestations by 75-85%, improving the quality and marketability of vegetables.
Cost - Benefit:
By effectively controlling piercing-sucking pests, it reduces crop losses, increases crop yields by 10-25%.
User Testimonials:
 "Pymetrozine 50% WDG successfully controlled the aphid problem in our apple orchard, and the apples grew healthily with good quality." – Orchard Manager, United States

Q1: Can it be used in organic farming?
A1: No, pymetrozine is a synthetic insecticide and not approved for use in organic farming systems.
Q2: How long does the insect control effect last?
A2: Under normal conditions, it provides effective pest control for 7-14 days. The duration may be affected by factors such as weather conditions, pest and crop growth.
Q3: Is it safe for subsequent crops?
A3: Yes, after proper aeration and following the recommended pre-planting interval, it has little impact on subsequent crops. However, it is recommended to conduct a small-scale germination test before large-scale planting of sensitive crops.
Q4: What crops are sensitive to residues?
A4: Some leafy vegetables (such as lettuce, spinach) and root crops (such as radish, carrot) may be more sensitive to pesticide residues. Avoid planting these crops immediately after application.

Insect Growth Regulators: Such as pyriproxyfen, for synergistic control of pests with different life cycles.

Botanical Insecticides: Like neem oil, suitable for use in organic or low-residue-requirement farming systems.
