The insecticide bifenazate is a bifenazate-based acaricide that appears as white solid crystals. Cas 149877-41-8 bifenazate is a novel acaricide with broad control spectrum, safety, strong knockdown ability, stable performance, not affected by light, heat, etc., resistant to rain erosion, good persistence, and good against It is friendly to beneficial insects and natural enemies, and can quickly reduce the number of harmful mites. It kills both eggs and adult mites, and more thoroughly prevents harmful mites. It is more sensitive to harmful mites that are difficult to control, such as two-spotted spider mites, and has a long lasting effect. Protects crops from damage for a long time and is ideal for integrated pest management.
The insecticide bifenazate is a new type of selective foliar acaricide that is not systemic and is mainly used to control active spider mites, but it has an ovicidal effect on other mites, especially two-spotted spider mites. The mechanism of action is a unique effect on the γ-aminobutyric acid (GABA) receptor in the central nervous system of mites. It is effective at all developmental stages of mites and has egg killing activity and knockdown activity against adult mites (48-72 hours). It has minimal impact on predatory mites, has no impact on plant growth, and has long-lasting effectiveness.
Physicochemical properties of bifenazate ester 149877-41-8
Solubility (20°C): 2.1mg/L in water; in organic solvents (g/L): 24.7 in toluene, 102 in ethyl acetate, 44.7 in methanol, 95.6 in acetonitrile; distribution coefficient (n-octanol/water) :LogPow=3.5.

bifenazate 149877-41-8 usage technology
1. The insecticide bifenazate has strong ovicidal effect but poor sex. It should be used when the insect population base is small (early in the growing season). When the insect population base is large, it needs to be mixed with sex snail killers.
2. The insecticide bifenazate has no systemic properties. To ensure the efficacy, when spraying, ensure that both sides of the leaves and the surface of the fruit are sprayed evenly.
3. It is recommended to use the insecticide bifenazate at an interval of 20 days, and apply it up to 4 times per year for each crop, and use it alternately with other acaricides with different mechanisms of action.
4. It is not recommended to mix the insecticide bifenazate with organophosphorus and carbamate.
The difference between bifenazate 149877-41-8 and etoxazole
1. bifenazate
1. Function and characteristics
(1) The main effect of the insecticide bifenazate on killing mites is on the γ-aminobutyric acid receptors in the central nervous system of mites. It has a good effect on the entire developmental stage of mites. It has ovicidal activity and knockdown activity on adult mites. The action time is particularly fast. Death of mites can be observed 36 to 48 hours after application.
(2) At the same time, the duration of bifenazate is very long, and the lasting effect is 20-25 days. Difenazine has very little effect on predatory mites and has no effect on plant growth. Because bifenazine is not affected by temperature, its effect on mites is very stable. In addition, it is very safe for bees and natural enemies of predatory mites, and is environmentally friendly.
2. Prevention and control objects
The pesticide bifenazate has a particularly wide range of control targets, including: two-spotted spider mites, honey locust spider mites, apple spider mites, citrus spider mites, southern claw mites, and spruce claw mites. It has no effect on rust mites, flat mites, broad mites, etc.
2. Etoxazole
1. Function and characteristics
(1) Etoxazole can inhibit the embryogenesis of mite eggs and the molting process from young mites to adult mites. It is effective on eggs and young mites, but has no effect on adult mites, but it has a good sterility effect on female adult mites. . Therefore, the best time to control it is in the early stages of mite damage. It is highly resistant to rain and lasts for up to 50 days.
(2) When using etoxazole, 11% etoxazole suspension can be diluted 5000-7500 times with water for spraying. This will maximize the effectiveness of etoxazole.
2. Prevention and control objects
Etoxazole mainly controls red spider mites on apples and citrus. It also has excellent control effects on mites such as spider mites, Eotetranychus mites, Panonychus mites, Two-spotted spider mites, and Tetranychus cinnabar on crops such as cotton, flowers, and vegetables.

(2) The insecticide bifenazate is not fast-acting, so it is best to use it in advance when the insect population base is small. If the insect population base is large, it needs to be mixed with other fast-acting acaricides; at the same time, because bifenazate is not systemic In order to ensure the effectiveness of the medicine, the pesticide should be sprayed evenly and comprehensively when applying.
(3) It is recommended that the insecticide bifenazate should be used at an interval of 20 days, and should be applied no more than 4 times per year to a single crop. It is best to use it alternately with other acaricides with other mechanisms of action. Do not mix with organophosphorus and carbamate. Note: bifenazate is highly toxic to fish, so it should be used away from fish ponds and is prohibited from being used in paddy fields.
