Aphids are typical piercing-sucking pests that parasitize various crops such as wheat, corn, cotton, vegetables and fruit trees all year round.
They mainly suck sap from tender shoots, young leaves and immature fruits, causing severe damage to crops.
Infested crops suffer curled, shrunken and yellowed leaves that fail to conduct normal photosynthesis, resulting in stunted plant growth,
dwarfing and poor shoot development. Meanwhile, aphids secrete large amounts of honeydew which adheres to the surface of leaves and
fruits. It not only clogs plant stomata, but also induces sooty mold disease, covering leaves and fruits with black mildew and seriously
impairing crop yield and fruit quality.
More importantly, aphids act as major vectors of crop viral diseases. While feeding on sap, they rapidly transmit viruses to healthy plants and
trigger large-scale outbreaks of viral diseases, which greatly raise the risks of yield reduction or even total crop failure.

Products Applications
When aphids break out massively, timely application of high-efficiency, low-toxicity and low-residue pesticides is recommended. Pesticides
should be used alternately to prevent aphid resistance formation. Pesticide spraying shall be conducted in key periods including the early
infestation stage, crop tender shoot stage, pre-bloom and post-bloom stages to reduce pest population density.
Available pesticides include imidacloprid, acetamiprid, thiamethoxam, beta-cypermethrin and flonicamid, which shall be diluted and sprayed
in accordance with instructions. Compound pesticides are preferred for the control of resistant aphids to achieve better efficacy
Precautions
1. Focus spraying on aphid gathering sites such as leaf undersides, tender shoots, young buds and flower buds, ensuring even and thorough
coverage without missing any area.
2. Spray pesticides on sunny days from 9 a.m. to 11 a.m. or after 4 p.m., avoiding windy, high-temperature and rainy weather.
3. Strictly follow the pesticide safety interval period. Pesticide application is prohibited before the harvest of fruits and vegetables to ensure
agricultural product safety.
4. Alternate pesticides with different modes of action to delay the development of aphid resistance.
Small in size yet highly destructive, aphids should never be underestimated. Conduct regular field inspections and carry out timely control
upon sporadic aphid occurrence. Delayed control will not only increase prevention costs, but also lead to crop yield losses.
Avoid blind pesticide application in aphid management. Adhere to the principle of priority prevention and integrated pest management, and
combine green prevention measures with scientific pesticide use. This approach can effectively eliminate aphids, protect farmland ecology
and stabilize and increase crop yields.
