Potted plants have been reported to uptake VOCs and help “cleaning” the air. This paper presents results of a laboratory study in which two species (peace lily Boston fern) three kinds substrates (expanded clay, soil, activated carbon) were tested monitored on their capacity deplete formaldehyde CO2 glass chamber. Formaldehyde selected as indicators evaluate biofiltration efficacy 28 different ...

Pesticide-free, 3-D, spacer fabrics (Plant Armor Generation (PA Gen) 1 and 2) were investigated for proof-of-concept as an insect barrier to protect plants improve plant agronomics organic farming. The time 50% penetration (TP50) tobacco thrips, Frankliniella fusca (Hinds) adults in laboratory Petri dish bioassays was 30 175 min PA Gen 2, respectively, 12 the control (a commercially available, ...

the potato tuberworm, phthorimaea operculella (zeller), is a major pest of potato in both store and field. in this research, host preference, biology and life table parameters of this pest were studied on leaves of 12 potato germplasm including seven commercial cultivars (agria, ausonia, sprit, satina, savalan, kondor, morene) and five iranian clones (pi396156-5, pi397045-15, pi397097-2, pi3970...

Under laboratory and glasshouse conditions, the insecticidal activities of essential oil obtained from leaves tea tree plant by steam distillation was evaluated against cotton aphid, Aphis gossypii. The results showed that affected aphid population causing a higher mortality A. This study 50 μL/mL concentration caused 85.67% after 24 hrs exposure time when used as contact treatment. However, mo...

The effects of drought stress, Phytophthora cinnamomi infection and their interaction on water relations growth were examined for 28 days two year-old potted trees Eucalyptus obliqua (L’Hér.). There significant stress plant photosynthesis, stomatal conductance, biomass accumulation, potential at turgor loss point the bulk modulus elasticity. E. was successfully infected but showed only mild sym...

Camellia is a genus of evergreen shrubs or trees, such as C. japonica, sinensis, oleifera, etc. A group beneficial soil microorganisms, arbuscular mycorrhizal fungi (AMF), inhabit the rhizosphere these spp. total eight genera Acaulospora, Entrophospora, Funneliformis, Gigaspora, Glomus, Pacispora, Scutellospora, and Sclerocystis were found to be associated with plants Glomus and/or Acaulospora ...
