Control Whiteflies with APHISTAR
Insecticide
Whiteflies are prevalent plant pests found in greenhouses and are known to transmit various plant diseases. Both adult whiteflies and their nymphs feed by piercing the phloem of plants and sucking out the fluids. Severe whitefly infestations can reduce plant vigor, causing symptoms such as stippling, leaf yellowing, drying, stunted growth, and premature leaf drop. On cucurbits, whiteflies can cause a condition known as "silver leaf" by injecting phytotoxins.
In addition to causing direct plant damage, whiteflies also play a role in spreading plant viruses. Typical symptoms of viral infection include yellow mosaics, yellow veins, curled leaves, stunted growth, and thickened veins. Moreover, whiteflies excrete excess honeydew that can disrupt photosynthesis and facilitate the growth of sooty mold.
Due to their small size, rapid reproduction, long migration distances, and high resistance to pesticides, whiteflies have become major pests in crops like tomatoes, peppers, eggplants, cucumbers, and cowpeas. Traditional pesticide spraying is often time-consuming, labor-intensive, has a short effective duration, and may not yield satisfactory results. Therefore, it is crucial to find efficient ways to control whitefly infestations.
Sunjoy Agro recommends the use of APHISTAR for foliar spraying to effectively control whiteflies. APHISTAR (106 g/L Acetamiprid+133 g/L Flonicamid OD) combines two active ingredients with different modes of action, enhanced with a methylated plant oil adjuvant. APHISTAR has excellent systemic properties, rapid action, prolonged effectiveness, and strong permeability, making it a superior choice for controlling whiteflies.
In April 2024, we conducted a field experiment on eggplants in Taizhou. The results showed that the mortality rate of pests after being treated with APHISTAR was over 90%. There were hardly any live pests visible in the field, and a layer of whitefly carcasses was scattered on the eggplant leaves and the ground.
