Bean Rust Control under Field Conditions with Systemic and Contact Fungicides.

Residues and Dissipation Kinetics of Two Imidacloprid Nanoformulations on Bean (Phaseolus vulgaris L.) under Field Conditions

The current study investigates the dissipation kinetics of two imidacloprid (IMI) nanoformulations (entitled: Nano-IMI and Nano-IMI/TiO2) on common bean (Phaseolus vulgaris) seeds under field conditions and compares them with 35% Suspension Concentrate (SC) commercial formulation. To do so, it sprays P. vulgaris plants at 30 and 60 g/ha within green bean stage, sampling them during the 14-day p...

Establishing systemic rust infections in Cirsium arvense in the field

An existing method to induce systemic rust infections in creeping thistles (Cirsium arvense) using an insect vector, the weevil Ceratapion onopordi, was successfully applied in the field. Urediniospores of Puccinia punctiformis were experimentally transmitted to naturally grown thistles, to our knowledge for the first time resulting in systemically infected shoots in an established thistle popu...

Cypress Canker Control with Fungicides

Cypress canker caused by Seiridium cardinale was controlled by benomyl and chlorothalonil but not by tribasic copper sulfate. Cypress canker has been present in California since 1927 where it has caused considerable damage to planted Monterey cypress, Cupressus macrocarpa (6). The popularity of this California native range and usually canker disease appears, but some uninformed people still pla...
