Synthesis and insecticidal activity of new bis-benzoylphenylurea compounds(Ⅱ)
A new chemical structure category of pyrethroids was synthesized. The tests in insecticidal activity was reported.
The bioassay results showed that the main insecticidal substances of these 10 testing strains were proteins.
D. insecticidal element: some actinomycetes produce antibiotics such as abamectin, sterilization element.
All of the stream sites with detectable insecticidal proteins were located within 500 metres of a corn field.
This article discusses the patterns of phosphine, the directions for USES, the correlation of ct product with insecticidal rate and sealing. Phosphine is used widely allover the world.
The result shows that the source of insecticidal and fungicidal activity strains in the symbiotic or epiphytic actinomycetes from Marine animals and plants are abundant.
A method was established for determination of a 7% d-cyphenothrin insecticidal aerosol using an ultrasound extraction pretreatment followed by gas chromatography (GC).
Extracted pyrethrins from pyrethrum dried flower by super critical CO2 . is a paste called oleoresin which isn't suitable to formulate insecticidal products either use in household or crops.
The iris is a perennial aquatic herb, it narrow leaf also contain volatile aromatic oil, is refreshing Tongqiao, bone health Xiaozhi, insecticidal sterilization.
