Thrips on Roses

Thrips are tiny, slender insects characterized by fringed wings and unique mouthparts that are asymmetrical in shape. Most species of thrips feed on plants by puncturing them and extracting their contents, although a few species act as predators.

While some thrips species play a beneficial role as pollinators or predators of other insects and mites, many others are considered pests that pose a threat to commercially important crops. Under suitable conditions, particularly in greenhouses, thrips populations can rapidly multiply due to the absence of natural predators and their ability to reproduce asexually. This proliferation can cause annoyance to humans. Thrips are commonly found in greenhouses, as well as indoor and outdoor gardens, and they inflict damage on plants by sucking their sap and scraping fruits, flowers, and leaves. Affected plant leaves may exhibit paleness, discoloration, and a silvery appearance, ultimately leading to their demise. Injured plants display twisting, discoloration, and scarring.

Thrips are highly active insects that feed in large groups. They tend to leap or fly away when disturbed. They are attracted to a variety of host plants, including onions, beans, carrots, squash, and various other garden vegetables, as well as flowers such as gladioli and roses. Both adult thrips and wingless larvae are particularly drawn to white, yellow, and other light-colored blossoms.

Effectively managing thrips involves maintaining the garden and reducing potential breeding sites for these pests. This includes promptly removing plant debris from the ground, especially when it is still green. Thrips lay their eggs in slits they create in the stems of living plants. Vigilance is crucial, and early detection of problems is essential. Regularly check your plants for signs of damage and clusters of pests where leaves connect to stems. It is important not to delay taking action. The use of blue sticky traps is beneficial for monitoring adult thrips populations.

When addressing thrips infestations, it is recommended to utilize the safest and most proven products available.

Introducing MAGNETO® 10 EC from Magneto Greenlife:

MAGNETO® 10 EC is a powerful insecticide offering broad-spectrum control with systemic, contact, and stomach action. It is specifically designed to combat a range of pests, including aphids, thrips, whiteflies, bollworms, and mites on roses. Additionally, it effectively targets aphids, whiteflies, thrips, caterpillars, and leaf miners on snow peas.

This brand new insecticide, MAGNETO® 10 EC, is formulated with a natural herbal extract mixture containing two key active ingredients: Azadiractin and Matrine. Azadiractin, derived from the neem tree, is a naturally occurring substance that belongs to a class of organic molecules called tetranortriterpenoids. It shares structural similarities with insect hormones known as “ecdysones,” which regulate the metamorphosis process from larva to pupa to adult. Azadiractin acts as an “ecdysones blocker,” disrupting the insect’s production and release of these crucial hormones. As a result, insects are unable to molt, effectively interrupting their life cycle. Azadiractin may also function as a feeding deterrent for certain insects. While insect death may take a few days depending on the life cycle stage, insects exposed to minute quantities of Azadiractin become quiescent and cease feeding. Residual insecticidal activity can be observed for up to 7 to 10 days or longer, depending on the insect species and application rate. Azadiractin is commonly used to control various pests such as whiteflies, aphids, thrips, fungus gnats, caterpillars, beetles, mushroom flies, mealybugs, leaf miners, and gypsy moths on food crops, greenhouse crops, ornamentals, and turf.

In addition to Azadiractin, MAGNETO® 10 EC also incorporates Matrine, a natural plant agent extracted from wild medicinal plants like Sophora Flavescent. Pure Matrine, the active ingredient, is a white crystal that is soluble in water and alcohol. It exhibits slight alkalescence and maintains excellent stability as a salt. Matrine acts on the nervous system of pests, leading to breath inhibition and disrupted movement.

MAGNETO® 10 EC provides enhanced, fast, and effective control of a wide range of insect pests on both edible crops and ornamentals. It boasts 100% natural characteristics, ensuring no chemical residues remain, and offers the following benefits.

MAGNETO® 10 EC is composed of two natural herbal ingredients, Azadiractin and Matrine, making it an ideal choice for organic farming. This insecticide provides a non-persistent residual effect due to the short-lived nature of Azadiractin and Matrine, ensuring minimal concerns regarding residues and pre-harvest intervals. Its suitability for organic farming is further enhanced, offering peace of mind to growers.

Ensuring excellent food and environmental safety, MAGNETO® 10 EC is formulated using a new safe EC formulation. It exhibits extremely low acute toxicity to humans, ensuring the safety of applicators and end-users. When applied at recommended rates, it demonstrates excellent food safety, allowing growers to comply with residue Maximum Residue Limits (MRL) and Pre-Harvest Intervals (PHI). For optimal results, apply at a rate of 0.5ml per liter for foliar applications.
