1. About Bifenazate
Bifenazate is a new type of selective foliar acaricide. It has a unique mode of action and was originally considered to be a type of neurotoxin, which has a unique effect on the γ-aminobutyric acid (GABA) receptors of the central nervous system of mites.
2. Product features
(1) Wide range of control targets. Bifenazate is mainly used to control harmful mites on crops such as citrus, strawberries, apples, peaches, grapes, vegetables, tea, and stone fruit trees. The control targets include two-spotted spider mites, soapberry spiders, apple spider mites, bamboo spider mites, citrus spider mites, southern small claw mites, spruce small claw mites, etc., but it is basically ineffective against rust mites, flat mites, and Guangming mites.
(2) It has a contact effect and no systemic effect. Bifenazate has no cross-resistance with other current miticides. It has both egg-killing activity and knockdown activity against adult mites. It is effective against all stages of harmful mites (eggs, nymphs, larvae, and adult mites). Mites can be seen dead after 36-48 hours. In the field, it can achieve an ideal control effect in 3 days. It has minimal impact on predatory mites and beneficial insects and is safe for plant growth.
(3) It is not sensitive to temperature and has a long lasting effect. Bifenazate is not affected by temperature and is not sensitive to low or high temperatures, which do not affect its effect. Therefore, its effect on mites is very stable. At the same time, the lasting effect of bifenazate is relatively long, up to 20-25 days.
3. Usage
(1) To control red spider mites on citrus trees, orange and grapefruit, rust mites, and panonychus mites, spray 1800-2500 times of 43% bifenazate suspension; to control two-spotted spider mites and red spider mites on apple and pear trees, spray 2000-4000 times of 43% bifenazate suspension; to control papaya red spider mites, spray 2000-3000 times of 43% bifenazate suspension.
(2) To control strawberry two-spotted spider mites and red spider mites, spray 2500-4000 times of 43% bifenazate suspension; to control watermelon and Hami melon two-spotted spider mites and red spider mites, spray 1800-2500 times of 43% bifenazate suspension; to control pepper tea yellow mites and red spider mites, spray 2000-3000 times of 43% bifenazate suspension; to control eggplant two-spotted spider mites and cinnabar spider mites, spray 1800-2500 times of 43% bifenazate suspension; to control flower red spider mites and yellow spider mites, spray 2000-3000 times of 43% bifenazate suspension.
(3) In use, bifenazate is often mixed with acaricides such as etoxazole, spirocyclofen, clofentezine, pyridaben, hexathiapyr, etc., or their mixed products are used to achieve the purpose of improving rapid effectiveness, reducing resistance, etc., and improving the control effect.
Precautions
(1) When it comes to bifenazate, many people confuse it with cypermethrin. In fact, these are two completely different products. To put it simply: bifenazate is a special acaricide (red spider), while cypermethrin also has a caricidal effect, but it is mainly used as an insecticide (aphids, cotton bollworms, etc.)
(2) Bifenazate has poor rapid effect. It is best to use it in advance when the insect population is small. If the insect population is large, it needs to be mixed with other rapid acaricides. At the same time, since bifenazate is not systemic, in order to ensure the efficacy, the spray should be sprayed as evenly and comprehensively as possible.
(3) It is recommended to use bifenazate at intervals of 20 days, and a single crop should be applied no more than 4 times a year. It is best to use it alternately with other acaricides with other mechanisms of action. It should not be mixed with organophosphates or carbamates. Note: Bifenazate is highly toxic to fish. It should be used away from fish ponds and is prohibited in paddy fields.
