Features of Buprofezin
1. Buprofezin has a strong contact action against pests and also exhibits stomach toxicity. It is particularly lethal to younger nymphs, but its effectiveness significantly decreases against nymphs older than the third instar. The recommended dosage cannot directly kill adult insects, but it can shorten their lifespan, reduce egg-laying capacity, and prevent eggs from hatching normally. Even if larvae hatch, they will die quickly, thereby reducing the population of the next generation. Buprofezin has some penetration ability in crops and can be absorbed by the leaves or leaf sheaths, but it cannot be absorbed and translocated by the root system.
2. Buprofezin is a selective insect growth regulator with strong selectivity against pests. It is widely applicable to vegetables, rice, wheat, potatoes, citrus, cotton, and tea plants. It effectively controls leafhoppers and planthoppers on rice, leafhoppers on potatoes, whiteflies on citrus, cotton, and vegetables, as well as various pests such as scale insects, armored scale insects, and mealybugs on citrus. It is highly effective against whiteflies, planthoppers, leafhoppers, and scale insects, but ineffective against caterpillars like diamondback moths and cabbage loopers.
3. Buprofezin acts slowly and is best used at the early stages of pest occurrence when densities are low. Generally, nymphs begin to die 3-5 days after application, coinciding with their molting period, and the peak mortality is typically reached 7-10 days after treatment. The direct control period for pests is around 15 days, with a total effective duration of approximately one month. When pest density is high, it should be mixed with fast-acting insecticides. Buprofezin has no cross-resistance with mainstream neonicotinoid insecticides or pyrethroid insecticides, allowing it to be combined with products such as imidacloprid, nitenpyram, lambda-cyhalothrin, bifenthrin, chlorpyrifos, and pymetrozine.

Application
1. To control vegetable whiteflies, such as the tobacco whitefly, use a 20% Buprofezin wettable powder diluted to 1000-2000 times. Spray evenly. For controlling tea green leafhoppers, black scaly whiteflies, and gall mites during the non-harvest period and early stages of the pests, use a 25% Buprofezin wettable powder diluted to 1000-1200 times. Spray evenly.
2. To control rice white-backed planthoppers and brown planthoppers, apply 50-80 grams of 25% Buprofezin wettable powder per acre, mixed with 60 kg of water for even spraying. Spray once during the egg hatching peak of the main generation and its previous generation to the peak stage of early nymphs. Focus on spraying the middle and lower parts of the plants.
3. To control citrus scale insects and whiteflies, use a 25% Buprofezin suspension agent diluted to 800-1200 times. Begin spraying before the emergence of arrowhead scales, during the early stages of nymphs, or at the onset of the initial phase of whiteflies. Ensure the solution is sprayed evenly.
