Spirodiclofen is a new type of acaricide with a new mechanism of action, with contact killing effect and no systemic property. It mainly inhibits the fat synthesis of mites and blocks the energy metabolism of mites. It is effective in all stages of development of mites, including eggs.

It works by inhibiting lipid synthesis, has no cross-resistance with current acaricides on the market, and has additional insecticidal properties.

Spirodiclofen is a chemical substance with a white powdery appearance and no special smell. It has a good killing effect on the eggs, larvae and nymphs of harmful mites, and is ineffective against adult mites, but it has the effect of inhibiting the hatching rate of female mites. effect.

Features of Spirodiclofen

1. New structure and unique mechanism of action: the active ingredient of spirodiclofen is tetrakis-diclofen, and the 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.

2. Wide spectrum of killing mites and strong adaptability: mites are very effective against red spider mites, yellow spiders, rust ticks, tea yellow mites, cinnabar spider mites and two-spotted spider mites, etc. It can be used for citrus, grapes, etc. It is suitable for the control of mite infestation of fruit trees and solanaceous crops such as eggplant, pepper and tomato. In addition, Mite Dangerous has a very good control effect on pests such as pear psyllid, elm oyster scale and leafhopper.

3. Kill both eggs and young: the effect of killing eggs is particularly excellent, and it also has a good contact killing effect on young nymphs. Although mite danger cannot kill female adult mites quickly, it has a good sterilization effect on female adult mites. 96% of the eggs laid by female adult mites could not hatch and died in the late embryonic stage after being exposed to the pesticide.

4. Long duration: Spirofen has a long duration, and it can control the damage of Panonychus citrus for 40-50 days in production. After spirodiclofen is applied to the leaves of crops, it is resistant to rain erosion, and the normal performance of the drug effect will not be affected by moderate rain after 2 hours of spraying.

5. Low toxicity, low residue, good sex. It is very harmful to crops under different temperature conditions, and has low toxicity to humans, animals and crops. Suitable for pollution-free production.

6. No mutual resistance: It can be mixed and used with most pesticides (except strong basic pesticides and copper preparations). Mixing with other acaricides with different action mechanisms can not only improve the resistance of spirodiclofen, but also facilitate the control of mite resistance.

The advantage of spirodiclofen is that it has good efficacy and long-lasting effect, but it also has a fatal weakness, that is, the quick-acting property is not good, so in most cases, spirodiclofen needs to be compounded with abamectin or bifenazate for quick-acting Sexual acaricide use.

Applications of Spirodiclofen 

1. Uniform spraying: This product controls eggs, nymphs and adult females of harmful mites through contact killing, and has no systemic properties. Therefore, when spraying with water, the product should be sprayed as evenly as possible to ensure that the liquid is sprayed on the leaves. Both sides of the fruit and the surface of the fruit can exert its medicinal effect to the maximum extent.

2. Application time: For the control of Panonychus citrus, it is recommended to apply it in the early stage of the damage of the mites, so as to give full play to the characteristics of the long-term persistence of the mites.

Spring use case 1:

When the damage of red spiders and yellow spiders reaches the control index (the number of eggs per leaf reaches 10 or 3-4 nymphs per leaf), use 4000-5000 times of uniform spray to control red spiders and yellow spiders for about 50 days. After that, if the population of red spiders and yellow spiders rises again, one-time acaricides (such as pyridaben, clofenac, abamectin, etc.) can be used.

Autumn medication:

In September and October, when the population of red spiders and yellow spiders reaches the control index, use 4000-5000 times of liquid to spray again or mix it with other chemicals according to the situation of mite infestation, so as to control the harvest of citrus and clear the garden in winter.

3. Frequency of application: Only apply once during the citrus growing season, and use it in rotation with other acaricides with different acaricidal mechanisms, which can effectively control resistant mites and reduce the risk of spider mites developing resistance to acarids

Precautions for spirodiclofen

1. If it is used in the middle and late stages of the infestation of citrus panonychia, the number of adult mites is already quite large. Due to the characteristics of mites that kill eggs and young mites, it is recommended to use acaricides with good sex and short residual effect, such as Avermectin Mixed use of antibiotics, etc., can not only quickly kill adult mites, but also control the recovery of the number of harmful mites for a long time.

2. Considering resistance management, it is recommended that in one growing season (spring and autumn), the number of times of use of mite danger should not exceed twice.

3. The main mode of action of mites is contact and stomach poisoning, and it has no systemic effect. Therefore, it should be sprayed evenly on the whole plant, especially on the back of leaves.

4. It is recommended to avoid using the medicine when the fruit trees are blooming.
