Trunk injection is a targeted delivery of pesticides, insecticides, nutrients, or other plant protection materials into the stem trunk woody plants as an alternative to spraying soil drenching. has historically been used for disease and pest management high-value forest tree species ornamental when aerial applications are problematic due spatial problems health-related concerns. An interest in ...

Bovine aortic smooth-muscle cells, bovine aortic endothelial cells, and IMR-90 human embryonic lung fibroblasts were tested to determine their ability to use cysteine or cysteine metabolites as a source of sulphate (SO4). Cells were incubated in SO4-depleted medium containing [3H]glucosamine plus 0.2 mM-cystine, 0.3 mM-cysteinesulphinic acid or 0.3 mM-sulphite (SO3). The [3H]chondroitin sulphat...

A convenient and highly efficient procedure for the synthesis of 3,4-dihydropyrimidin-2-(1H)-one/thione derivatives via one-pot three-component Biginelli condensation of arylaldehydes,urea/thiourea and ethyl/methyl acetoacetate in the presence of Zn(SO4)2.7H2Oas anefficient, readily and inexpensive catalyst under solvent-free conditions have been studied. Thisprotocol ha...

The high temperature properties of Rb3H(SO4)2 have been studied by calorimetry, impedance spectroscopy and X-ray powder diffraction under moderate humidification. At ~205 °C the conductivity of Rb3H(SO4)2 increases sharply, rising from 3.3×10 −5 to 1.9×10 S/cm, suggestive of a polymorphic, superprotonic phase transition. This conductivity anomaly is accompanied by an endothermic thermal event w...

Trunk injection with penicillin has been tested to control citrus huanglongbing (HLB), but side effects and environmental safety must be assured before approval of penicillin injection can be considered. We investigated effects of penicillin injection on densities of Candidatus Liberibacter asiaticus (Las) in leaves, as well as culturable bacterial populations in rhizospheres and petioles of gr...
