Is the Flower Protector effective against red spiders?
The editor is here to answer questions about floral clinic knowledge, such as whether the Flower Protector is effective against red spiders, and will next share this knowledge with everyone.
The Flower Protector is a common pesticide, and many flower enthusiasts have several boxes on hand. Many flower enthusiasts want to know if the Flower Protector is effective against red spiders? So we will discuss this with the flower enthusiasts based on their actual usage experience, using the old version of the Flower Protector as an example.
The main ingredients of the Flower Protector are imidacloprid and abamectin, with 1.6% imidacloprid and 0.2% abamectin. The instructions for use state that it is used for the prevention and control of caterpillars and aphids on cruciferous vegetables. There is no mention of red spiders. Let's first look at these two ingredients.
Imidacloprid: Mainly used for the prevention and control of sap-sucking insects (can be alternated with dinotefuran at high and low temperatures - use imidacloprid at high temperatures and dinotefuran at low temperatures), controlling pests such as aphids, planthoppers, whiteflies, leafhoppers, and thrips; it is also effective against certain pests from the Coleoptera, Diptera, and Lepidoptera orders, such as rice striped stem borers, rice leaf rollers, and潜叶蛾. However, it is ineffective against nematodes and red spiders.
Abamectin: A 16-membered macrolide compound with fungicidal, insecticidal, acaricidal, and nematicidal activities. Abamectin has stomach poison and contact insecticidal effects on mites and insects, but it cannot kill eggs. Red spiders, also known as citrus rust mites, belong to the Arachnida class and Acarina order, not insects. Therefore, abamectin has an insecticidal effect on red spiders but cannot kill the eggs.
From the ingredients of the Flower Protector, we can see that the content of abamectin is only 0.2%, so there is an insecticidal effect on red spiders, but it is not very strong. This also confirms the spraying experience of some flower enthusiasts.
Regarding the feedback on the Flower Protector's effectiveness against red spiders, some flower enthusiasts say it is effective. The editor guesses this is because there are not many red spiders and they are in the early stage, making it not difficult to kill them. For those who say the Flower Protector is ineffective against red spiders, they may be on plants with a higher number of red spiders, where it naturally has no effect.
Red spiders have strong resistance and are very stubborn. Generally, two pesticides are used alternately to kill them. Let's see what pesticides the flower enthusiasts are using.
Hexythiazox, Pyridaben, Jinmanzhi, Pyriproxyfen, Aikachan, have all been tried for a year, and I will summarize the pros and cons.
When killing red spiders, it is necessary to spray insecticides and ovicides together, both sides of the leaves, the potting soil, and the surroundings of the pot, leaving no死角. Ovicides include Pyridaben and Pyriproxyfen, both of which are good. Insecticides such as Jinmanzhi and Aikachan are also effective. Hexythiazox is not recommended because it can burn the leaves of succulents, hydrangeas, and roses...
Jinmanzhi or Aikachan alternated with Pyridaben or Pyriproxyfen, at a concentration of 3000 times, every 3 days, for 3-4 consecutive sprays, with monthly prevention, the effect is not bad, you can try it.
Red spiders must be treated with insecticides and ovicides together because red spider eggs reproduce every 3 days, and the reason for spraying every 3 days is also due to this. If you use a watering can to spray water, it may wash them away at the moment, but there will be more by the end of the day. Wait until I introduce the effects of various pesticides to you downstairs!
Hexythiazox, Jinmanzhi, and Aikachan are very effective in killing adult red spiders, while Pyridaben and Pyriproxyfen kill eggs. In summary, insecticides and ovicides must be mixed together, and everyone must spray both sides of the leaves.
