What is insecticide buprofezin?

Buprofezin is a thiadiazine insect growth regulator acting as moulting inhibitor for the persistent larvicidal action against some Coleoptera.Buprofezin is a type-1 chitin synthesis inhibitor insecticide used to control hemipteran insects.Cas 69327-76-0 Hemiptera and Acarina. Because the chemical itself is very specific to the certain insects, It is a most successful insect growth regulator in the world for Homopterous insects such as plant hoppers, whiteflies and scale insects, and is widely used in more than 80 countries. Insect growth regulators (IGRs) as third-generation insecticides have a specific mode of action on insects and a lower toxicity against vertebrates than most conventional insecticides.

Buprofezin is an insecticide used for control of insect pests such as mealybugs, leafhoppers and whitefly on vegetable crops. It is a growth regulator, acting as an inhibitor of chitin synthesis.It is banned in some countries due to its negative environmental impacts, being especially toxic to aquatic organisms as well as non-target insects, though is of low toxicity to humans and other.

Buprofezin (2-tert-butylimino-3-isopropyl-5-phenylperhydro-1,3,5-thiadiazin-4-one) is an insecticide with a thiadiazine structure. Its uses are on citrus fruit, tomato and lettuce. Buprofezin is a chitin synthesis inhibitor and it controls various pests such as whitefly and scales.

What is the function of insecticide buprofezin?

Buprofezin is an inhibitor of chitin synthesis in insects. It mainly inhibits the synthesis of chitin in insects, interferes with the normal metabolism of insects, and hinders the formation of new cuticles of insects, so that nymphs moult deformed and die slowly. It has the characteristics of strong selectivity, high insecticidal activity, long residual period, low toxicity and less dosage.

Buprofezin is a type-1 chitin synthesis inhibitor insecticide used to control hemipteran insects. It is generally considered safe for humans, but its persistent nature may become a health hazard if long-term exposure takes place.

Buprofezin a member of the buprofezin compound family, serves as an effective insecticide for the control of various pests. This synthetic pyrazole derivative exists as a white, crystalline solid. It exhibits solubility in water, ethanol, and methanol. The mechanism of action of buprofezin involves disrupting the normal functioning of the insect′s nervous system. By binding to the octopamine receptor in the insect′s nervous system, it hinders the action of octopamine, leading to paralysis and eventual death of the pest.

How to use insecticide buprofezin

(1) Buprofezin has a strong contact effect on pests, and also has a stomach poisoning effect. It has a strong poisoning ability against young nymphs, and its poisoning ability against nymphs above 3 instars significantly reduces. The recommended dose cannot directly kill adults, but it can Shorten its lifespan, reduce the amount of eggs laid, and make the eggs unable to hatch normally. Even if the larvae hatch, they will die soon, thereby reducing the number of occurrences of the next generation. Buprofezin has a certain penetration ability to crops, but absorbs and conducted by roots.

(2) Buprofezin is a selective insecticide that inhibits the growth and development of insects. It has strong selectivity to pests and widely use in vegetables, rice, wheat, potatoes, citrus, cotton, tea trees, etc., and can effectively control rice. Leafhoppers and Planthoppers on potatoes, Leafhoppers on potatoes, Whiteflyaceae on citrus, cotton and vegetables, Scaloidaceae, Scalocidae and Mealyococcus on citrus, etc., to whitefly, Planthoppers, leafhoppers and scale insects are highly effective, but it is ineffective against Lepidoptera pests such as diamondback moth and cabbage caterpillar.

(3) The action of buprofezin is slow, so it applys at the early stage of pest occurrence and when the density is low. Generally, 3-5 days after spraying, the nymphs begin to die when they molt, and the number of dead insects reaches the peak 7-10 days after spraying. Generally, the period of direct control of insects is about 15 days, and the total effective period can reach about 1 month. When the insect population density is high, it mixs with quick-acting agents. Buprofezin has no cross-resistance with mainstream neonicotinoid insecticides and pyrethroid insecticides, and can interact with imidacloprid, nitenpyram, lambda-cyhalothrin, bifenthrin, chlorpyrifos, and pyrethrin Compounds such as ketones.

(4) Buprofezin has a wide range of applications in various crops, including rice, citrus fruits, apples, grapes, cotton, tea, mangoes, and solanaceous vegetables. However, it is not suitable for cabbage and radishes.

What is the method of useinsecticide buprofezin?

(1) Buprofezin to control vegetable whitefly, whitefly, etc., use 1000-2000 times liquid of 20% buprofezin wettable powder, and spray evenly; when preventing and controlling small green leafhoppers, blackthorn whitefly, and gall mites on tea trees, it is best to use it when the tea leaves. In the early stage and the young stage of pests, 1000-1200 times liquid of 25% buprofezin wettable powder evenly.

(2) Buprofezin to control rice white-backed planthopper, brown planthopper, etc., 50-80 grams of 25% buprofezin wettable powder per mu, mixed with 60 kg of water and sprayed evenly. In the blooming stage of young nymphs, spray once each, focusing on the middle and lower parts of the plants.

(3) Buprofezin to control citrus scale insects, whitefly, etc., 800-1200 times of 25% buprofezin suspending agent , before the sting of scale insects such as scorpion or the early stage of nymph occurrence, or the early peak of whitefly occurrence Start spraying, and the liquid medicine  evenly.

What are the characteristics insecticide buprofezin

Buprofezin has strong contact and stomach poisoning effects. It is often used in the control of rice and vegetable pests and diseases. It can be used to control various fruits such as citrus, potato, rice, cucumber, wheat, tomato, planthoppers on melons, and leafhoppers. , whitefly, cotton whitefly, rice brown planthopper, scorpion, citrus mealybug, red round scale and other Homopteran pests, and has persistent killing activity on some coleopteran larvae and larvae.

Buprofezin is a chitin synthesis inhibitor, which reduces egg viability, prevents molting of nymphs, and suppresses oviposition (egg deposition) by adult females.Buprofezin reduces the total insect population in the next generation and achieves a long-lasting effect.

Buprofezin provides not only a strong contact action.Buprofezin is safe to non-target organisms such as natural enemies or beneficial insects it is an ideal active for IPM.

Features of insecticide buprofezin

1. Buprofezin is a selective insecticide that inhibits the growth and development of insects. It has a strong contact effect on pests and also has stomach toxicity. It has a certain penetration ability to crops and can be absorbed by crop leaves or leaf sheaths, but cannot be absorbed and conducted by roots. It has a strong poisonous ability to young nymphs, but its poisonous ability to 3rd and older nymphs is significantly reduced. It has no direct lethality to adults, but it can shorten its lifespan and reduce the amount of eggs laid, and most of the eggs laid are sterile eggs. Even the hatched larvae will die soon, thereby reducing the number of occurrences of the next generation.

2. It has a strong selectivity to pests, and is only effective against hemiptera whitefly, planthopper, leafhopper and scale insects, and is ineffective against lepidopteran pests such as diamondback moth and cabbage caterpillar.

3. The efficacy of the drug is slow, usually 3 to 5 days after application. The nymphs begin to die when they molt, and the number of deaths reaches the peak 7 to 10 days after application. Therefore, the drug has a long period of efficacy. Generally, the period of direct control of insects is about 15 days. It can protect natural enemies and exert the effect of natural enemies in controlling pests. Up to about 1 month.

4. It is safe to crops and natural enemies at commonly used concentrations, and is an ideal pesticide variety in integrated pest control.

5. Buprofezin is often mixed with insecticide ingredients such as monosultap, imidacloprid, beta-cypermethrin, beta-cyhalothrin, abamectin, nitenpyram, pymetrozine, etofenproxil, pyridaben, etc. Compounding, production of compound insecticides.

Mechanism of Action insecticide buprofezin

Buprofezin belongs to the type 1 chitin synthesis inhibitors.

Buprofezin exhibits strong contact and certain stomach toxicity against pests in the order Hemiptera. It is not systemic within plants but has some penetration ability and can be absorbed by leaves or leaf sheaths. It effectively controls nymphs by inhibiting their molting, with higher efficacy against younger instars. While it does not directly kill adults at recommended doses, it can shorten their lifespan, suppress female oviposition, and reduce egg hatching rates to control pest populations.

Buprofezin is harmless to most beneficial insects such as Neuroptera (lacewings) and Hymenoptera (parasitic wasps). With the assistance of natural enemies, it further aids in pest population control. However, it is ineffective against Lepidoptera and Thysanoptera insects and is not suitable for controlling these types of pests.

Main pest control targets insecticide buprofezin

Buprofezin its main targets for pest control are Hemiptera pests such as rice planthoppers, whiteflies, and scale insects. After the banning of chlorpyrifos, its use in citrus trees has rapidly increased, primarily targeting armored scales, soft scales, and mealybugs. It is also effective against aphids in vegetables and leafhoppers in tea trees.  

Agricultural Uses insecticide buprofezin

Insecticide, Acaricide, Insect growth regulator: For insect control in food crops and greenhouse ornamentals.

Buprofezin is a contact and ingested insecticide, active against Homoptera (whiteflies, leafhoppers, scale insects, etc.) in and on citrus, cotton, cucumbers, tomatoes, sweet potatoes, rice, etc.

Buprofezin is a insecticide which works as a chitin synthesis inhibitor. Buprofezin is used to control stubborn rice pests and is effective in controlling green leaf hoppers and white back plant hoppe rs for long durations.

Metabolic pathway insecticide buprofezin

Buprofezin gradually decomposes in soils under flooded and upland conditions, with half-lives of 104 and 80 days, respectively. After 150 days, five degradation products are identified as 2-tert- butylimino-5-(4-hydroxyphenyl)-3-isopropylperhydro- 1,3,5-thiadiazin-4-one, 3-isopropyl-5-phenylperhydro- 1,3,5-thiadiazin-2,4-dione, 1-tert-butyl-3-ispropyl-5- phenylbiuret, 1-isopropyl-3-phenylurea, and phenylurea. As minor products, 2-tert-butylimino-5- phenylperhydro-1,3,5-thiadiazin-4-one or buprofezin sulfoxide are found in the flooded or in the upland soils. Since neither formation of 14CO2 nor hydroxylation is observed in the sterile soils, buprofezin seems to have undergone complete mineralization in soils under both conditions through biological transformation by soil microorganisms.

Degradation insecticide buprofezin

Buprofezin was degraded under acidic conditions with half-lives (DT50) f 6-12 days (pH 4), 34 days (pH 6) and 65 days (pH 10) at 40 °C. Opening of the thiadiazinanone ring appeared to be the primary hydrolytic degradation pathway, to yield 1-tert-butyl-3-isopropyl-5-phenyl-2- thiobiuret and N-isopropyl-N-phenylurea as major products.

Buprofezin is stable to aqueous photolysis. The estimated DT50 of buprofezin in distilled water when exposed to UV light was 39 days. A more complex photodegradation pathway of buprofezin in methanol was reported recently (Datta and Walia, 1997) with DT9 values of 4 hours and 15 days under UV and sunlight irradiation, respectively.

Precautions for Buprofezin

1. Buprofezin has no systemic conduction effect, so it is required to spray evenly and thoughtfully.

2. Do not use it on cabbage and radish, otherwise there will be symptoms of phytotoxicity such as brown spots or albino green leaves.

3. It cannot be mixed with alkaline agents and strong acid agents. It is not suitable for repeated, continuous, high-dose use, generally only 1-2 times a year. When spraying pesticides continuously, pay attention to alternate or mix them with pesticides with different insecticidal mechanisms to delay the development of pesticide resistance in pests.

4. The medicine should be kept in a cool, dry place out of reach of children.

5. This medicine should only be used as a spray, not as a poisonous soil method.

6. It is poisonous to silkworms and some fishes. It is prohibited in mulberry gardens, silkworm rooms and surrounding areas.
