Imidacloprid 70% WG

Scope and Usage Method

Crop / Place Target Pest Dosage (formulation amount per mu) Application Method
Cabbage Aphid 1.5–3 g / mu Spray
Technical Requirements

Timing of application: Spray at the onset of the aphid population peak (early‑peak occurrence) to ensure effective control; make sure the spray coverage is uniform.
Application conditions: Apply when temperatures are low and wind speed is minimal—preferably in the early morning or late afternoon. On clear days, spray between 08:00 and 17:00; cease spraying if the temperature rises above 28 °C.
Crop sensitivity: The product is relatively phytotoxic to melon and bean crops. Avoid drift of the spray solution onto these susceptible crops during application.
Product Performance

This product is a systemic insecticide that exhibits both stomach‑poison and contact activity. It provides a long residual effect and offers good control of sucking‑mouthpart pests, particularly aphids.

Thiamethoxam 25% WG
Technical Requirements
Recommended application timing: Apply the pesticide at the early stage of wheat aphid infestation, generally during the wheat seedling stage and the booting and heading stage.
Ensure uniform and thorough spray coverage during use, especially on the infested and damaged sites of the target pests.
Do not apply the pesticide if strong wind is forecasted or if rainfall is expected within one hour.
The pre-harvest interval for this product when used on wheat is 14 days, with a maximum of 2 applications per growing season.
Product Performance
This product is a second-generation neonicotinoid insecticide. Its mode of action is similar to that of first-generation neonicotinoid insecticides such as imidacloprid, but it has higher insecticidal activity.
It exerts stomach toxicity, contact toxicity and systemic action against pests, and features rapid action onset and long residual efficacy.
It is applicable for controlling wheat aphids.

Cyromazine 75% WP
Technical Requirements
Dilute the product with water and spray during the period from the initial outbreak stage to the peak damage stage of Liriomyza sativae (American leafminer) on cucumber. This pest is prone to severe outbreaks during dry seasons with low precipitation, so targeted control measures should be strengthened accordingly.
Do not apply the product on windy days, or when rainfall is forecast within 1 hour.
Product Performance
This product exerts its efficacy via systemic translocation within the host plant: it induces morphological deformities in eggs and larvae, inhibits the normal metamorphosis of larvae into pupae, thereby preventing full eclosion of adults or suppressing adult emergence. It delivers the combined effects of egg sterilization, larval control, and adult fly expulsion, and can effectively control Liriomyza sativae infestations on cucumber.

Abamectin 1.8% EC

Product Performance
Abamectin is a biological insecticide and acaricide produced via microbial fermentation. It has strong stomach poison and contact toxicity against harmful mites, and features prominent translaminar activity. After being sprayed on plant foliage, the formulation rapidly penetrates leaf tissues. Mites (both adults and nymphs) will show paralysis symptoms, become inactive and stop feeding after contacting or ingesting the formulation, and die within 2 to 4 days.

Precautions
It is recommended to rotate this product with other acaricides that have different modes of action.
This product is toxic to bees and silkworms. Avoid impacts on surrounding bee colonies during application. Use is prohibited near flowering plants during their blooming period, as well as in the vicinity of silkworm rearing facilities and mulberry orchards. Keep application sites away from aquaculture areas, as this product is toxic to fish and other aquatic organisms. It is strictly forbidden to wash application equipment in rivers, ponds and other water bodies.
This product must not be mixed with strongly alkaline substances such as lime sulfur mixture and Bordeaux mixture.
Open the seal with caution to prevent splashing of the formulation. Waste packaging shall be rinsed, flattened and deeply buried, or returned to the manufacturer for proper processing or recycling.
Wear protective clothing, masks or respirators, and rubber gloves during formulation preparation and application to avoid contamination of skin and eyes. After application, change clothes promptly, and wash hands, face and any contaminated skin thoroughly.
Thoroughly clean spraying equipment before and after application. Wastewater from cleaning shall not be allowed to contaminate rivers or other water sources. Unused remaining formulation shall be sealed and stored properly.
Application is strictly prohibited in areas where natural enemies such as Trichogramma (egg parasitoid wasps, commonly known as "赤眼蜂" in Chinese agricultural context) are released.
Used containers shall be disposed of properly. They must not be repurposed or discarded arbitrarily.
