Buprofezin is a low-toxic biomimetic insecticide of the thiadiazine type insect growth regulator, and is also known as Falconing, Promethrin, and Dimethrin (Jing).
The product inhibits the synthesis of insect chitin and interferes with metabolism, causing young (nymph) worms to molt abnormally and die slowly, or cause abno
rmal growth and death due to abnormal growth. The effect is generally seen in 3~7 days.
1. Product features
Buprofezin is a selective insecticide that inhibits the growth and development of insects. It has a strong contact-killing effect on pests and also has a gastric toxic effect. It has certain
permeability to crops and can be absorbed by crop leaves or leaf sheaths, but cannot be absorbed and conducted by roots. The ability to kill young nymphs is strong, and the ability
to kill nymphs above 3 instars is significantly reduced. It has no direct killing power on adults, but it can shorten its life span and reduce the amount of eggs laid. Most of the eggs pro
duced are sterile eggs. Even the hatched larvae die quickly, which can reduce the number of next generations.
It has strong selectivity to pests. It is only effective against whiteflies, planthoppers, leafhoppers and scale insects of the order Hemiptera. It is not effective against Lepidoptera pests
such as Plutella xylostella and Pieris rapae.
The effect of the medicine is slow, generally 3~5 days after application. The nymphs begin to die when they molt, and the number of deaths reaches the highest peak 7-10 days after
application. Therefore, the effective period is long. Generally, the direct control period is about 15 days, which can protect natural enemies and exert the effect of natural enemies to
control pests. Up to about 1 month.
It is safe to crops and natural enemies at common concentrations and is an ideal pesticide variety in integrated pest control.
Buprofezin is often mixed with insecticide ingredients such as dimethoprim, imidacloprid, beta-cypermethrin, lambda-cyhalothrin, abamectin, nitenpyram, pymetrozine, etofenprox,
pyridaben, etc. Production of compound pesticides.
2. Control object
The scope of application is suitable for vegetables, rice, potatoes, citrus, cotton, fruit trees, tea trees, etc. The object of control has sustained larvicidal activity against some Coleoptera,
Hemiptera and Acarina, and can effectively control Cicadaceae and Planthoppers on rice, Cicadaceae on potatoes, and larvae on citrus, cotton and vegetables. The whitefly family, the
superfamily Coccidae, Coccidae and Mealcoccidae on citrus. It has a good control effect on planthoppers, leafhoppers, whiteflies and scale insects of the order Hemiptera. The efficacy
period is more than 30 days.
On vegetables, it is mainly used to control whitefly, small green leafhopper, cotton leafhopper, whitefly, long green planthopper, white back planthopper, laodelphax striatellus, lateral polyp
hagous tarsal mite (tea yellow mite), type B Bemisia tabaci, greenhouse whitefly, etc.
In fruit trees, it is mainly used to prevent and control scale insects such as blue scale insects and whitefly on citrus trees, scale insects such as mulberry white scales on peach, plum, and apricot trees, small green leafhoppers, and Japanese tortoiseshell insects on jujube trees. 3.Instructions
(1) Vegetable pests control whitefly, spray with 10% Buprofezin EC 1000 times. Or use 25% Buprofezin wettable powder 1500 times liquid and 2.5% bifenthrin EC 5,000 times liquid to
mix and spray.
(2) To prevent and treat small green leafhoppers and cotton leafhoppers, spray with 20% Buprofezin wettable powder (emulsifiable concentrate) 1000 times liquid.
(3) To control whitefly, spray with 20% Buprofezin wettable powder (emulsifiable concentrate) 1500 times.
For the prevention and treatment of long green planthopper, white-backed planthopper, Laodelphax striatellus, etc., spray with 20% Buprofezin wettable powder (emulsifiable concentrate)
2000 times.
(4) To prevent and treat yellow mites, spray with 20% Buprofezin wettable powder (emulsifiable concentrate) 2000 times.
(5) To control B-type whitefly and greenhouse whitefly, spray with buprofezin wettable powder (emulsifiable concentrate) 1000 to 1500 times.
(6) Control of fruit tree pests such as scale insects such as citrus blue scale insects and whitefly, spray with 25% Buprofezin (wettable powder) 800~1200 times liquid or 37% Buprofezin
suspension 1200~1500 times liquid . When controlling scale insects such as blue scale insects, spray the pesticide before the pests come out or at the early stage of the occurrence of
weak insects, and spray once per bag. When controlling whitefly, start spraying from the early stage of whitefly occurrence, once every 15 days, and spray twice, focusing on the back of
the leaves.
(7) To control scale insects and small green leafhoppers such as peach, plum, apricot, mulberry white scale, use 25% Buprofezin (wettable powder) 800~1200 times liquid or 37% Bupro
fezin Suspension 1200~ 1500 times liquid spray. When controlling scale insects such as mulberry scales, spray the medicine in time after the nymphs hatch to the young nymph stage, and
spray the medicine once per bag. When controlling small green leafhoppers, spray the pesticide in time at the beginning of the pest occurrence or when there are more yellow-green dots
on the front of the leaf, once every 15 days, and spray twice, focusing on the back of the leaf.
(8) Control of rice pests: White-backed planthoppers and leafhoppers: spray once at the beginning of the primary pest generation of young nymphs. Use 50 grams of 25% Buprofezin wetta
ble powder per mu, mix with 60 kilograms of water and spray evenly. Focus on spraying the middle and lower part of the plant.
(9) For the prevention and control of rice brown planthopper, spraying once in each of the egg incubation period to the young nymph period of the main generation and the previous generati
on can effectively control its damage. Use 50 to 80 grams of 25% Buprofezin wettable powder per mu, spray with 60 kg of water, and focus on spraying the middle and lower parts of the plant.
(10) When tea tree pests control tea tree green leafhopper, black thorn whitefly, and gall mites, use the medicine in the non-picking period of tea and the early stage of pests, and spray with
1000~1200 times solution of 25% Buprofezin wettable powder evenly.
Precautions
1. Buprofezin has no systemic conduction effect and requires even and thoughtful spraying.
2. Do not use on cabbage and radish, otherwise there will be brown spots or green leaves albino.
3. It cannot be mixed with alkaline or strong acid agents. It is not suitable for multiple, continuous, high-dose use, generally only 1-2 times a year. When spraying continuously, pay attention
to alternate or mixed use with agents with different insecticidal mechanisms to delay the development of resistance of pests.
4. The medicine should be kept in a cool, dry and out of reach of children.
5. This medicine should only be used as a spray, not as a poisonous soil method.
6. Toxic to silkworms and some fishes, it is forbidden to use in mulberry gardens, silkworm houses and the surrounding area to prevent the liquid from polluting water sources and river pon
ds. Water from the pesticide application field and the waste liquid from cleaning the pesticide application equipment shall not be discharged into river ponds and other waters.
