How does  Spirodiclofen work?

The active ingredient of spirodiclofen is quaternary ketodiafen, and its mechanism of action is to inhibit the synthesis of fat in harmful mites. It has no cross-resistance with existing acaricides, and is suitable for controlling harmful mites that are resistant to existing acaricides

①It has a broad spectrum of killing mites, and can effectively prevent and control mites, red spiders, rust ticks, etc. on crops such as citrus, stone fruit, pome fruit, grape, strawberry, and nuts.
②It has contact killing effect on the eggs, nymphs and adult mites of spider mites, and the egg killing effect is better.
③Long-lasting effect, for example, the control time of citrus red spider is as long as 40~60d.
④The agent has strong lipophilicity and is resistant to rain erosion. After 3 hours of application, the efficacy will not be affected in the event of rain.
⑤ It is a chronic acaricide, and obvious effect can be seen after 5~7 days of spraying. Therefore, if the number of harmful mites is large, it should be combined with fast-acting acaricides (such as pyridaben, fenothrin, The mites are mixed and used in equal proportions.
