Koppert adhesive cards for control and monitoring of whitefly, thrips, and fungus fly 10 cm*25 cm (10 pieces)

Koppert Horiver Yellow Sticky Cards for controlling and monitoring whitefly, thrips, fungus gnats, 10 × 25 cm – 10 pieces Koppert Horiver Yellow cards are agricultural sticky cards designed for monitoring and tracking flying insects inside greenhouses, fields, and nurseries. They are primarily used to observe whitefly, thrips, airborne mites, leaf miners, and fungus flies. These cards rely on the attractive yellow color for insects, with a sticky surface that helps capture insects when they contact the card. Sticky cards are important tools in integrated pest management programs because they are not only used for trapping but also help farmers detect early infestations and estimate insect density before they spread widely. Therefore, they are a practical choice for farmers who want continuous crop monitoring and timely pest control decisions instead of waiting for visible damage on plants. Description of Koppert Horiver Yellow Cards Horiver Yellow cards from Koppert are designed as simple and effective means to monitor flying agricultural pests. The yellow color attracts many pests moving among plants, while the strong adhesive keeps them stuck on the card surface, aiding in counting and tracking infestation levels over time. Markings or grids on the card help in estimating insect numbers easily, which is important for farmers and agricultural engineers when assessing infestation severity or monitoring control program success. The cards are equipped with holes for easy hanging on wires or supports inside the greenhouse or between plant rows.

Insects Monitored by the Cards Koppert Horiver Yellow cards are used to monitor several flying insects prevalent in crops, including: whitefly thrips airborne mites leaf miners fungus gnats some small flying insects attracted to yellow in the cultivation area Suitable Uses Yellow sticky cards are used in greenhouses to monitor insect movement between crop rows. They can also be used in nurseries and seedling production areas to detect early infestations before plants are moved to the field. They are also suitable for open farms when properly distributed in high-risk areas. These cards help farmers determine whether an infestation is in its early stages or increasing, and assist in locating insect congregations inside the greenhouse or farm. They are not just traps but also monitoring and diagnostic tools to support precise pest control decisions. Usage Method Distribute the sticky cards evenly inside the greenhouse or field between rows, hanging the card on a wire or suitable support. It is preferable to position the card near the top of the plant, about 20 to 30 cm above the plant surface, and gradually raise it as the crop grows to stay in the insect activity zone. In open fields, distribute the cards at appropriate distances based on the size of the area, infestation severity, and wind direction. Inside greenhouses, place them to cover rows and high-risk entry points such as entrances, ventilation openings, and sides of the greenhouse. Check the cards regularly, count the insects as needed, and replace them when full, dusty, or when the adhesive weakens or becomes less visible. Recommended Number of Cards for Use The number depends on crop type, cultivation area, infestation level, and location. As a general guideline, more cards are used inside greenhouses due to higher insect concentration, while in open fields, distribution depends on area, wind, and infestation zones. For monitoring, start with a limited number of cards and increase as insect numbers rise. When a clear infestation occurs, consider the cards as part of an integrated control program, not a complete substitute for other measures. Important Notices When Using Do not place the cards too low or far from insect movement. Do not leave cards for long after they are full of insects or dust. Regularly inspect the cards to evaluate infestation development. Do not rely solely on the cards during severe infestations; use them as part of an integrated pest management program. Avoid touching the sticky surface with hands to maintain adhesion efficiency. Keep the cards away from children and pets. In greenhouses, focus on entry points and ventilation openings, as these are common insect entry points. Why Are Sticky Cards Important for Farmers? Many agricultural pests start with low numbers and can spread quickly if not detected early. For example, whitefly and thrips can cause direct plant damage and may also transmit other problems between plants. Early monitoring gives farmers the chance to act before the infestation becomes widespread. Koppert Horiver Yellow cards help you see what is not easily visible during quick plant inspections. When insects appear on the cards, farmers or agricultural specialists can assess the risk level, adjust control programs, or use additional solutions before significant crop damage occurs.
