Diflubenzuron is an insecticide of the benzoylurea class. [2] It is used in forest management and on field crops [ 3 ] to selectively control insect pests, particularly forest tent caterpillar moths , boll weevils , gypsy moths , and other types of moths . [ 1 ]
The insecticidal activity of the BPUs was discovered serendipitiously at Phillips-Duphar who commericalised diflubenzuron in 1975. [1] Since then, many BPUs were commercialised by many companies. BPUs accounted for 3% of the $ 18.4 billion world insecticide market in 2018. [3] Lufenuron, was the largest selling BPU in 2016, selling for $ 112 ...
Flufenoxuron is an insecticide that belongs to the benzoylurea chitin synthesis inhibitor group, which also includes diflubenzuron, triflumuron, and lufenuron. [1] Flufenoxuron is a white crystalline powder. It is insoluble in water, is not flammable, and is not an oxidizer.
Bioactivity of novaluron is usually much greater than that of insecticides diflubenzuron and teflubenzuron and the compound is at least as active as other insecticides from its developmental generation, for example chlorofluazuron and lufenuron. [11]
Bistrifluron is an insecticide of the benzoylurea class. [1] It is used to control chewing insects such as aphids, whiteflies, caterpillars, and termites. [2] [3] [4] It is not highly toxic to mammals, but bioaccumulation may be a concern. [2]
Commercial greenhouses typically employ the insect growth regulator diflubenzuron for control of fungus gnats and their larvae. It is applied to infected soil and will kill fungus gnat larvae for 30–60 days from a single application.
Structure of N-benzoyl-N′-phenylurea was first determined in 2010. [1] Molecules in this compound are approximately flat and exhibit high charge delocalization. Within the molecule an intramolecular N−H⋅⋅⋅O hydrogen bond is present forming pseudoaromatic 6-membered ring. [2]
Pyriproxyfen is a pesticide which is found to be effective against a variety of insects. [3] It was introduced to the US in 1996, to protect cotton crops against whitefly.It has also been found useful for protecting other crops. [4]
